    Introduction

    Upper limb congenital malformations are pretty rare but can result in severe limitation or

    loss of function in all areas of occupation because the use of arms and hands are essential for

    the performance of many activities. Children with impairment and disability, arising from upper

    limb dysfunction may require the provision of aids, equipment and other accommodations which

    can help them to successfully adapt and respond to meeting the demands of differing

    environmental contexts which they are going to encounter as they develop and grow to maturity.

    Assistive technology can be a valid means of helping to develop skills or maintain skills and can

    facilitate greater levels of independence.

    However, there appears to be little written about the lived experience of children with

    congenital upper limb dysfunction and their utilization of assistive technology for meeting self-

    care/personal activities of daily living. A key area of focus of this paper is to explore how

    assistive technology is used by adolescents with congenital upper limb dysfunction, when they

    are at an age where the desire for increasing autonomy, awareness of body image/self-identity

    and need to assert their independence away from with primary caregivers are likely to emerge as

    important factors during this transitional period. Questions being addressed include, Do

    adolescents with upper limb dysfunction have ease of access to the right types of aids which

    enable them to competently manage essential self-care routines (eg personal grooming tasks

    such as washing, drying and brushing hair and dressing activities), if so what routes are followed

    for obtaining these aids/assistive technology and how readily available are they? Do the assistive

    aids currently available make a real qualitative difference to both the main service user and their

    care givers (if applicable) in respect of factors such as time, effort and organization required for

    carrying out self-care tasks, or do alternative strategies/techniques and problem-solving bridge

    the gap in the absence of assistive technology which could make a difference in these areas?

    What are the concerns of the primary caregivers (within families) in these situations and how are

    issues of independence, during this period of transition for their child, managed?

    Before these issues can be addressed, it is important to understand the pathogenesis of

    congenital upper limb conditions and their course as these factors determine the extent to which

    the functional anatomy and biomechanics of the upper limb are likely to be affected and greatly

    influence future management and therapeutic interventions. Subsequently the next section of this

    paper provides an overview of the literature on etiology and classification of congenital upper limb

    deficiencies.

    Etiology and Classification of Congenital Upper limb Deficiencies

    Congenital anomalies are uncommon. They affect 1- 2 % of newborns. Of these

    approximately 10% of children have upper extremity irregularities (Kozin, 2003). Normal fetal

    development occurs in three stages (1) the pre-differentiation period (weeks 1 and 2), (2) the

    embryonic period (weeks 3-8) and (3) the fetal period (weeks 9 term) (Van Heest, 1996). Eight

    weeks after fertilization embryogenesis is complete and all limb structures - bones, ligaments,

    joints and muscles are in place and undergoing rapid growth. The ongoing process of normal

    skeletal ossification for the upper limb results in the formation of the long bones - clavicle,

    humerus , radius and ulna the short bones - metacarpals, proximal, middle and distal

    phalanges of the hand and flat bones the scapula and carpals. Primary centers of

    ossification are present in all fetal long bones by week 12. Most congenital anomalies of the

    upper extremity occur during the fetal phase of development (Kozin, 2003). Upper limb

    deficiencies are defined as reduction defects of the humerus, radius, ulna, hand and phalanges.

    (Ephraim et al, 2003).

    Most frequently malformations of the hand and arm result from gene variation which give

    rise to specific syndromes or with associated abnormalities of other organ systems, (Van Heest,

    3

  • 8/8/2019 Special Topics Paper 1 - For Merge

    4/38

    1996). Additionally, exposure to environmental teratogens or indeed gene- environmental

    interaction may result in limb deficiencies (Ephraim et al, 2003). However, the causes of some

    upper limb anomalies are not always known.

    Morrissey and Weinstein (2001) note that the classification of congenital limb anomalies

    has not been clearcut and most orthopedic clinicians tend to use a combination of systems to

    categorize and to precisely describe these deficiencies . However, a widely adopted system is

    that which was proposed by C.H Frantz and R. ORahilly in 1961 and augmented by A.B

    Swanson in 1976. (Froster-Iskenius & Baird, 1990). This is also now augmented by a system of

    classification developed by the International Standards Organization (ISO) and the International

    Society for Prosthetics and Orthotics (ISPO). (Morrissey & Weinstein, 2001). However for ease

    of reference this paper will use the descriptive terminology applied under the Frantz and O

    Rahilly system . This system places upper limb malformations within seven categories. These

    are as follows:

    1) Failure of formation of parts -

    2) Failure of differentiation

    3) Duplication

    4 ) Overgrowth

    5) Undergrowth

    6) Congenital Constriction band syndrome

    7) Generalized skeletal abnormalities

    1. Failure of formation of Parts:

    Failure of formation describes upper arms, forearms, wrists, hands or fingers that do not

    form completely or at all.

    Transverse deficiencies, i.e. those which extend across the entire width of the limb,

    linclude all naturally occurring congenital amputations which can apply to the shoulder, arm,

    forearm, carpals metacarpals and phalanges . The most common transverse deficiency is the

    4

  • 8/8/2019 Special Topics Paper 1 - For Merge

    5/38

    unilateral below- elbow amputation. Van Heest (1996) notes that this generally lends itself well

    to early fitting of a prosthesis . A child of between 6 12 months of age can be fitted with a

    simple paddle prosthesis initially with more sophisticated prostheses being applied as the child

    develops.

    Longitudinal deficiencies cover the gamut of deformities ranging from phocomelia, where

    the hand is attached to the trunk, to anomalies of the radius, ulnar and digits. Phocomelia is

    uncommon and is usually associated with the drug thalidomide having been taken in the first

    trimester of pregnancy. Surgery is not usually indicated in these cases and fitting of a prosthesis

    can be difficult due to the extreme shortening of the limb. (Kozin, 2003). Deficiencies of the

    radius most commonly result in partial to complete absence of this bone. The ulna in this

    instance is often subject to growth retardation and bowing. The thumb can be absent in upto

    85% of cases and remaining digits may be stiff. Hand function is reduced in these instances due

    to associated loss of thumb and digit function as well as acute deviation at the wrist joint.

    Bilateral incidence ranges from 40-60% in these cases. Unilateral deformities occur twice as

    often on the right side as on the left and boys are affected more frequently than girls in a 3:2 ratio.

    Radius deficiencies are commonly associated with named syndromes such as Holt- Oram

    syndrome or Thrombocytopenia Absent Radius (TAR) syndrome. The complete absence of

    skeletal parts of a limb is known as Amelia. (Froster-Iskenius & Baird, 1990)

    2. Failure of Differentiation

    Failure of differentiation, or separation, occurs when the basic unit is not fully formed.

    Synostoses, (or the joining of two bones by the ossification of connecting tissues) of the radius

    and ulna, carpus and metacarpals are examples of a lack of complete differentiation of parts in

    the upper limb. Van Heest (1996) notes that Syndactyly, or fusion of two fingers, is the most

    common congenital upper limb condition in the United States. Syndactyly can be successfully

    treated via surgical intervention providing this conducted when the child is between 6-18 months

    5

    6/38

    of age in order to avid tethering of skeletal growth and to facilitate subsequent normal digital

    development (Van Heest, 1996)

    3. Duplication

    Duplication, or polydactyly most commonly involves an extra thumb or little finger and

    central polydactyly is rare ( Morrissey & Weinstein, 2001). Polydactlyly of the little finger, without

    complications, can usually be successfully treated with excision during the newborn phase with

    normal hand function being preserved but more complex polydactylies may necessitate excision

    and reconstruction. Because of the functional importance of the thumb preaxial polydactyly

    (thumb duplication) surgery is not usually effected within the first year of birth as excision can

    easily disrupt thenar musculature and damage collateral ligaments. Central polydactyly will either

    entail leaving the digits conjoined, or attempting reconstruction to a five digit hand. However,

    even with reconstruction the involved digit may be subject to poor alignment and is likely to be

    smaller, weaker and stiffer. (Morrissey and Weinstein, 2001)

    4. Overgrowth

    A section of the hand or arm may be too large or too small affecting joint structure and

    function. However overgrowth deformities may affect the entire limb, forearm, hand, or digits.

    Most commonly, macrodactyly - non-hereditary enlargement of a digit - will result in seventy

    percent of children having an adjacent digit affected. (Van Heest, 1996)

    5. Undergrowth

    Van Heest (1996) states that undergrowth, or hypoplasia denotes complete formation of

    a part during the embryonic period of gestation but incomplete growth during the fetal period.

    The whole limb or any of its parts may be affected and can also occur with longitudinal anomalies

    of adjacent parts. The thumb is most commonly affected and hypoplasia in this instance can

    range from minor diminution with full function to total absence. Hand surgeon consultation is

    necessary to determine gradation of involvement and most appropriate procedures.

    6. Congenital Constriction band syndrome

    This results from tight bands of tissue around the arm, forearm, wrist or fingers. It can

    range from being mild to severe. If severe, part of the hand may be lost with amputation arising

    distal to the constricting band. Surgical interventions are recommended for all types of banding

    except those which present as amputations. (Morrissey & Weinstein, 2001). If a secondary and

    severe deformity is present such as gross distal lymphedema then interventions may occur when

    a child is still neonate otherwise surgical interventions within first 18 months is appropriate. (Van

    Heest, 1996)

    7. Generalized skeletal abnormalities

    This category covers a spectrum of malformations but includes congenital dislocations

    such as those occurring at the elbow. These may arise, for example from ulnar abnormalities and

    limitations in motion and reduced function of the forearm will result ( Morrisey & Weinstein,

    2001). In this instance the shoulder, wrist,or trunk need to be used to compensate and facilitate

    recreational activities and activities of daily living. This presentation is very uncommon and may

    not always be remedied by surgical interventions although elbow reconstruction might be feasible

    in some case.

    Abnormalities which involve limited proximal and distal radial physeal growth result in

    wrist deviation and bowing of the ulna . (Morrisey & Weinstein, 2001). Additionally with radial

    skeletal malformations there may be paralleled soft tissue deficiencies on the preaxial side of the

    hand, wrist and forearm and wrist extensors, pronator-flexor muscles, radial nerve and radial

    artery may all be severely affected. Children with longitudinal deficiencies of the radius may

    need to compensate for the absence of opposition by using spherical grip and lateral pinch and

    application of adaptive techniques for managing hygiene, feeding, and dressing are often

    necessary.

    The congenital abnormalities previously described highlight how performance in key

    activities of daily living are likely to be impaired from such malformations and the long-term

    effects of these pervasive conditions. However, surgical, medical and therapeutic interventions

    can potentially and substantially lessen deformity and improve function. Although failure of

    formation anomalies appear least common they are probably the most likely to have most impact

    on upper limb and hand function and are subsequently the main focus of this paper.

    Global Incidence of Upper Limb Deficiencies

    Morrissy & Weinstein (2001) note that in general there is little information on the

    incidence of congenital limb deficiencies. However, Giele et al (2001) in an eleven year

    population study of Western Australia found the prevalence of babies born with upper anomalies

    was 1 in 506. 46% of these had another nonhand congenital anomaly, 51% had bilateral hand

    anomalies, and 17% had multiple different hand anomalies. The most frequently occurring

    irregularities resulted from failures of differentiation (35%) duplications (33%), and failures of

    formation (15%). Upper limb anomalies were more frequent for boys, preterm and post-term

    births, multiple births and older mothers. No significant differences were found for ethnic groups,

    left and right sides or in babies who survived birth or those who died shortly after birth.

    Current and accurate data regarding the global incidence for all congenital disorders

    which affect the upper limb is difficult to gain. In the developed world national registries are

    maintained which provide statistics pertaining to incidence and epidemiology and focus in the

    literature in this field highlights concerns about management of surgical amputations arising

    from diseases such as diabetes and cancer or traumatic injury and implications for subsequent

    rehabilitation. (Ephraim et al, 2003). However, trying to find information pertaining to incidence

    of congenital malformations in the developing world is more difficult. Little could be found by way

    of statistical data for these populations and they do not appear to be well represented in research

    literature. There may be a number of reasons for this. Historically all types of birth defects have

    8

  • 8/8/2019 Special Topics Paper 1 - For Merge

    9/38

    been considered by multiple cultures to be stigmatizing or to be punishments for misdeeds and

    sins and a visitation of evil upon the child and family (Brent, 2004). In cultures where such belief

    systems still persist children with these birth defects are less likely to come to the attention of

    health and medical authorities/organizations who are a main source for keeping records.

    Additionally, where resources are scarce there may not be the commitment or infrastructure to

    support collection of data for these relatively rare conditions. True incidence of upper limb

    congenital malformations may also not be known due to non- recording of stillbirths or pre-natal

    detections of such deformities which may result in terminations.

    Brief Overview of the Functional anatomy of the Upper Extremity

    The upper limb is a remarkable and complex example of natural biomechanical

    engineering. A fully developed and unimpaired arm is comprised of multiple structures which

    allow smooth, efficient movements to occur. Hand motions are made more effective through

    proper positioning via the elbow, shoulder joint and shoulder girdle. Greatly simplified, the upper

    limb comprises of the shoulder girdle complex, the shoulder joint, the three long bones of the

    humerus, radius and ulnar , elbow and radioulnar joint, wrist and hand. The hand itself consists

    of 27 bones, 30 joints and 33 muscles and is innervated from three peripheral nerves. (Stanley &

    Tribuzi, 1992).

    The upper extremity is connected to the trunk via the sternum and skeletal attachment

    occurs at the sternoclavicular joint. (McMinn et al, 1993). However, most arm movements are

    facilitated by the combined actions of the three joints of the shoulder which consist of the

    sternoclavicular joint, the acromioclavicular and glenohumeral joint which is a lax, multi-axial ball

    and socket joint. It is supported by a network of muscles, ligaments and soft tissue and is one of

    the most mobile joints of the body. (Hamill & Knutzen, 1995). The sternoclavicular joint in

    isolation has little stability but acts as an axis for rotation of the shoulder girdle and absorbs

    lateral shock. (Jacobs, 1999). The acromioclavicular joint facilitates elevation and depression of

    9

  • 8/8/2019 Special Topics Paper 1 - For Merge

    10/38

    the scapula. (Hamill & Knutzen, 1995). The range of motion at the shoulder joint is extensive. It

    allows the arm to be moved through approx 180 degrees of flexion or abduction, 60 degrees of

    hyperextension, 75 degrees of hyper-adduction, 90 degrees of internal and external rotation, 135

    degrees of horizontal flexion and 45 degrees of horizontal extension. (Hamill & Knutzen,1995).

    The elbow joint is comprised of the distal end of the humerus, the proximal end of the

    ulna and the proximal end of the radius. whilst the radioulnar joint consists of proximal, distal and

    middle joints stabilized by ligaments.

    The wrist joint is made up of the distal ends of the radius and ulna and two rows of carpal

    bones and its movements are flexion, extension, radial deviation and ulnar deviation. (Jacobs,

    1995).

    The combination of shoulder and elbow/radioulnar joint movements, in concert with the

    hand, enables us to effect a myriad of movements essential for participation in occupations that

    require prehension, that is to say the use of the hand and fingers to grasp or pick up objects.

    (Anderson et al, 2002). Without this capability actions required for dexterously and precisely

    manipulating tools and utensils, catching a ball or fine motor tasks such as rolling a bead between

    the fingers are not possible. The wrist and hand are capable of precision and power because of

    multiple joints being controlled by a large number of muscles which originate in the forearm and

    enter the hand as tendons. Additionally the hand communicates a wealth of sensory information

    and feedback and deficits to the hand can result in loss of tactile discrimination and absence of

    capability for discerning the nature of objects by the sense of touch.

    The Challenges of Upper limb Deficiency and the Facilitation of Occupational Adaptation

    Due to the rarity of congenital upper limb deficiencies many clinicians and healthcare

    professionals may have limited or no experience of these conditions. However it is important that

    patients are able to access organized programs where knowledge and experience is available.

    10

    11/38

    The management of pediatric limb deficiency is a specialized and complex area of clinical

    practice. A multi-disciplinary team approach to these patients and families requires effective

    communication and ideally teams working with this type of presentation should be comprised of a

    physician, surgeon, prosthetist, physical therapist, occupational therapist, social worker or child

    psychologist who have knowledge of normal child development and are aware of the deviations

    from the norm which will occur as the child develops. With upper extremity deficient children

    there are many factors which come into play for influencing interventions. Therefore, assessment

    and treatment planning need to focus on function, growth, cosmetic deformity and the concerns of

    the family and child if successful outcomes are to be achieved. (Morrissey & Weinstein, 2001;

    Meier & Atkins, 2004).

    Function

    Interventions aimed at improving function for congenital upper limb or hand problems

    should address the ability to place the limb and hand in space, deficiencies in grasp, release, or

    pinch capabilities and improvement or maintenance of skin sensibility and mobility, and giving

    consideration to the degree to which physeal abnormalities are likely to affect musculoskeletal

    deformity both short-term and long-term. In some cases non-operative care may be indicated

    whilst in others reconstructive surgery or amputation may be advised as a means of optimizing

    function but much will depend on the condition being presented and the associated

    complications. (Waters, 2001).

    If a decision is made to fit a child born with congenital upper limb absence with an initial

    passive prosthesis, subsequent to amputation, then this can be made as early as when the infant

    is three months old . This is the age at which they begin to sit up and start to use their hands

    together for gripping activities and is also when the device can start to begin to become

    incorporated as part of their body image by parents thereby increasing the likelihood of their

    acceptance of the prosthetic.(Stark, 2001) However, before proceeding with the construction of

    any prosthesis there will always need to be a full evaluation and examination of the limb to

    determine current shape, extent of any scarring and bony areas which are likely to affect design,

    11

  • 8/8/2019 Special Topics Paper 1 - For Merge

    12/38

    comfort and flush fit. Children are potentially likely to have a series of prosthetic fittings as they

    grow and as their needs change. If a child retains a prosthesis it is likely to be activated when

    they are about 18 months of age for below elbow amputee and about 3 years of age for an above

    elbow amputee. As a child grows greater considerations need to be given for balancing function

    with cosmetic concerns. It is at subsequent evaluations that advantages and disadvantages

    about component parts are likely to be discussed with both the child and parents. Outcomes of

    these discussions will determine the composition of terminal devices, wrist, elbow, hinges, control

    mechanisms, harnessing and socket fitting. Assessments of range of motion and muscle

    strength will be recorded to determine how best to make the socket so that it causes least

    restriction of movement and facilitation of prehension with a terminal device should be a primary

    objective. (Stark, 2001)

    Growth

    A childs physical and emotional status constantly changes as he or she develops.

    Consequently the rehabilitation approach must be responsive to these maturational changes with

    regards to congenital upper limb deficiencies because developmental milestones are used as a

    guide when prescribing prosthetic devices. (Jain, 1996; DiCowden 1990). In the first year of life

    a child is physically developing strength proximo-distally and is learning to co-ordinate

    movements of trunk, and head with gross motor functioning of the limbs. For transradial

    unilateral and transverse forearm anomalies, Initial fitting of a light-weight supracondylar

    prosthesis, with a self-suspending socket, may be effected from 3 9 months of age to assist in

    gross motor development tasks, such as creeping and pulling to standing for example. At two

    years of age a child is attuned to processing information through the five senses, is able to

    ambulate and is beginning to develop manual dexterity. If initial fitting is made at this stage

    however, there may be a rejection of the prosthesis because the child is already starting to

    develop compensatory techniques by using their feet or trunk but these may be counter-

    productive to the development of normal movement patterns if left unchecked (Jain, 1996).

    Children with bilateral deficiencies also require early fitting but may not always benefit more from

    12

  • 8/8/2019 Special Topics Paper 1 - For Merge

    13/38

    bilateral prostheses unless they can be an adjunct to improving sitting and standing balance and

    the weight and complexity of hardware can be a major source of frustration for a child.

    Unilateral fitting in these instances may still be advisable with this being applied to the side where

    the child has developed a leading foot pattern (if this is known). However, children between 2- 6

    years of age can usually be fitted with a myoelectric or body-powered prosthetic with a terminal

    device providing that they do not have other cognitive and developmental limitations which might

    interfere with understanding 2-step commands, attention span or the ability to relate to

    bimanual prehension activities. The ability to use a prosthesis competently by age 2 is

    significant because at this stage of development the child is asserting some degree of self-

    sufficiency. Effort is concentrated in self-feeding, independent toileting, obtaining objects in the

    environment unassisted and gaining self-control over the body. This process can be delayed if

    the child is necessarily having to remain dependent on a caregiver for these seminal tasks and

    they may be significantly below their age level in relation to motor skill development an

    subsequent intellectual growth (DiCowden, 1990).

    Children with an amputation at the elbow level can generally be fitted with a lock and unlock

    elbow cable operated or switch control prosthetic, which acts as an assisting limb, at between 35

    -48 months if they can demonstrate understanding of the relationship between objects and the

    immediate environment but the Utah Myolectric elbow is not suitable for children under 14 (Jain,

    1996). At around 3 4 years of age children are going to become more aware of their limb

    deficiency and of the visible difference between themselves and other children but will not yet

    have capacity for building their own coping strategies. (Tonnacour and Shorgan, 2004) . This

    can be a difficult phase as the child may display social discomfort just as they are about to

    commence school.

    From six through to puberty children continue to develop co-ordination and social skills

    which may be demonstrated in involvement with scholastic endeavors, sports and other extra-

    curricular activities. This is the stage of development where Piagets concept of concrete

    operations is formalized by the individual being able to make connections between concrete

    13

  • 8/8/2019 Special Topics Paper 1 - For Merge

    14/38

    relationships. For instance they more readily understand mathematical quantities and proportions

    and can relate to basic scientific principles. Additionally, according to Eriksons theory of lifespan

    development feedback from peers , as well as adults, begins to have significance at this age

    and the child can achieve sense of competency with attaining age appropriate tasks or can have

    feelings of inferiority if they are not able to develop skills and to be recognized.

    DiCowden (1990) highlights that rehabilitation needs to actively take account of the needs of

    the child with congenital deficits or chronic at each particular age stage because disability can

    have dramatic developmental impact upon the child. Dicowden (1990) also advocates for

    multidisciplinary rehabilitation services being set up which assess and treat children all the way

    from infancy to late adolescence and which provide comprehensive evaluations taking into full

    consideration intellectual and psychosocial functioning in addition to physical and medical factors.

    The use of prescribed prosthetics, or other assistive technology is therefore subject to the

    childs different stages of development which will inherently bring them changing needs and

    challenges. Certainly, as children with congenital deficits reach adolescence they may need to

    deal with a number of psychosocial issues around independence, self-identity and body-image

    and these are discussed in a later section of this paper.

    Cosmetic Deformity

    Upper limb anomalies are a very apparent visible difference. As such individuals can be

    subject to stigma and negative perceptions associated with disfigurement with subsequent

    consequences of poor body image and loss of confidence. Depending on the nature and extent

    of the anomaly, some deformity may possibly be diminished through surgical interventions either

    through amputation or reconstruction. However, all children will gradually become aware of how

    socially orientated society is and by the time of adolescence most children do not want to be seen

    as different from their peers. However, children with this pronounced type of upper limb

    impairment need to come to terms with their difference whilst also being expected to be become

    more independent. Therefore challenges exist for rehabilitation teams to be able to provide

    14

  • 8/8/2019 Special Topics Paper 1 - For Merge

    15/38

    prosthetic devices which when in use are not only functional but also look aesthetic and lifelike.

    Additionally, any other assistive devices or technology used also has a requirement to be age

    appropriate and appealing for this group.

    FamilyConcerns

    The parents of an infant born with congenital upper limb dysfunction are likely to initially

    experience a sense of grief and guilt, in addition to lacking information about the nature of the

    cause and likely progression of their childs condition and how this will influence future

    development. Therefore, it is imperative that they have access to guidance from professionals

    who can provide education and advice which will enable them to make informed decisions about

    their child at each stage of growth. These decisions will have lifelong consequences for the child

    as they have a condition which they will need to adapt to and accommodate rather than having an

    illness that has an end point or a cure. In some circumstances functional use of a childs upper

    limb may be enhanced by amputation but this may be a difficult recommendation for parents to

    accept. DiCowden(1990) states that the family is the most important mediator of a childs

    development, and subsequently if parents remain grieved by their childs difficulties they cannot

    give the necessary feedback and guidance required for rehabilitation.

    Parents may benefit from counseling, psychotherapy and referral to support groups where

    they can be introduced to families who have gone through similar experiences. This can help

    allay fears and anxieties about the future, begin to give resolution to feelings of loss and

    disappointment whilst leading them to a point of acceptance and realistic hope that their child can

    reach their full potential. (Morrissy, Giavedoni, & Coulter O Berry ,2001) .

    Although initially born dependent, normally developing children, gradually move to greater

    independence and are capable of demonstrating considerable physical and psychological

    adaptability. Loss of upper limb function can greatly impact on all areas of occupational

    performance but children born with congenital disabilities affecting this extremity can also thrive if

    15

  • 8/8/2019 Special Topics Paper 1 - For Merge

    16/38

    they are provided with the right resources, assistive devices, technology and accommodations.

    The utilization of adapted performance techniques can also enable them to acquire skills and

    strategies for developing competence and mastering the environmental contexts in which they

    are placed. However, if a child does not have access to the appropriate remediations reduced

    opportunities for developing skills and autonomy is likely to result in diminished sense of personal

    causation, self-efficacy and self-esteem (Stoller, 1998).

    Children with a unilateral upper limb congenital deficiency are likely to cope well in most

    situations without a prosthesis or other assistive devices. They can learn to use their intact hand

    for most activities whilst often using their deficient, or shorter arm for steadying. Anomalous

    limbs are often still functional but orthoses and limb reconstruction are options for maximizing

    function. However, sometimes amputation maybe indicated but the goal should be to create the

    most functional limb possible which allows the individual to gain most life-satisfaction. (Carroll &

    Edelstein, 2006)

    Celikyol (1984) notes that problem-solving and the pursuit of sometimes unorthodox

    solutions are crucial strategies for effectively interacting with the environment and for facilitating

    the management and performance of activities of daily living when prosthetic aids may not

    always be wanted or feasible. Individuals with bilateral upper-limb absence, as in the case of

    phocomelia, may prefer to use their feet as arm substitutes for functional activities rather than

    cope with prostheses.

    The Thalidomide Society has highlighted some of the difficulties which can be experienced

    as a result of congenital bilateral upper limb loss. Many of these individuals have become adept

    at using their feet and toes as substitutes for arms and legs but are now finding that over-use of

    their lower limbs are resulting in knee and hip problems arising from joint degeneration which is

    affecting their ability to manage some tasks. Many thalidomide impaired people report that the

    length of time take for personal tasks such as washing and drying hair and dressing may take

    16

  • 8/8/2019 Special Topics Paper 1 - For Merge

    17/38

    four times longer than for anyone else. Even slight Injury (such as a stiff shoulder) can often

    result in not being able to carry out personal care activities until the injury has healed. Meal

    preparation can also be difficult and dangerous. For instance the cutting of vegetables, and the

    carrying of hot dishes, or lifting and moving of pans is often done in close proximity to the body

    because of reduced arm length and the lack of thumb and fingers means reduced grip and

    strength. Where hands are articulated at the shoulder it may not be possible to carry items at all.

    Additionally medication bottles or blister packs may be difficult to open because of a lack of a

    thumb or fingers. Also the lack of the fine pincer grip movements makes the picking up of small

    items such as coins and pills difficult to achieve.

    However, perhaps one the greatest challenges for children with this type of presentation as

    they grow older is learning to accept themselves as they are irrespective of the physical

    difference created by the upper limb deficiency.

    Psychosocial Issues and Adolescents with Congenital Upper Limb Dysfunction.

    The formation of a coherent personal identity is, in accordance with theories of

    psychosocial development, a primary task of adolescence. The model of life span development

    as posited by Erikson (1963) considers that during this period of transition failure to reach this

    goal may result in confusion relating to sexual identity, choice of employment and other roles

    performed as an adult. This stage of life may also be characterized by turmoil and stress as

    adolescents experience the physical changes of puberty, and increasing expectations from

    society at large as well as from family and peers as to how they should behave. The process of

    puberty often carries with it concerns and anxieties over physical appearance and body image

    and a desire to fit in with peers whilst also striving for a sense of ones own uniqueness and

    17

  • 8/8/2019 Special Topics Paper 1 - For Merge

    18/38

    forging adult relationships away from parents and the family. Over the past thirty years there

    has been a large amount of research interest in adolescent development. However this is in

    relation to the general population. Chamberlain and Kent (2005) state that this process maybe

    all the more challenging when childhood is marred by congenital or acquired disability. Rumsey

    and Harcourt (2004) also note that transitional periods including changing schools, jobs or

    neighbourhood can be particularly challenging for those with a physical difference because they

    need to develop new strategies for dealing with the reactions of unfamiliar people and for forming

    new relationships which go beyond initial encounters. Children with disability may experience

    less exposure to everyday events and therefore have fewer opportunities to learn and explore in

    the same ways as their age-related peers. Hostler et al (1989) affirm that the literature

    concerning psychosocial outcomes for children with disabilities points to themes of poor social

    adjustment, a sense of isolation and loneliness, fewer same-sex and opposite sex friends of

    similar age, increased dependence on others, less assumption of responsibility and less than

    average knowledge of sex.

    Adamson (2003) however, notes that overall, research literature regarding the

    psychosocial development, and personal experiences of adolescents with physical disabilities, is

    sparse and this appears to be particularly apt for individuals with congenital upper limb

    dysfunction. Adamson also highlights that there needs to be further exploration of the ways in

    which young persons with disabilities perceive and evaluate themselves.

    Van Dortsten (2004) also reports that current reviews of the literature fail to identify

    particular recommendations or innovations for guiding and integrating psychological, medical

    evaluation and treatment approaches for limb loss. However, young children are not initially

    intellectually aware of physical differences. In fact it is most likely the parents who will have

    difficulty adjusting to their childs disability. Initial reactions are likely to be those of shock,

    anxiety, guilt and fear for the future, and there maybe some difficulty with the initial bonding

    process (Rumsey and Harcout, 2004) . Parents may be concerned about the reactions of other

    18

  • 8/8/2019 Special Topics Paper 1 - For Merge

    19/38

    people and how this will affect childs feelings and level of self-acceptance as they develop.

    (Carroll & Edelstein, 2006). Families can vary considerably in their strategies for coping with a

    child with a physical difference. These may range from open discussion , denial of its existence

    or over-protection. (Rumsey and Harcourt, 2004). Parental concerns, however, may in turn be

    transmitted to the child and assimilated with subsequent consequences for the childs own

    perceptions of emerging body image and feeling of self-worth (Rumsey and Harcourt, 2004).

    The child themselves may at some stage indeed begin to experience some degree of self-

    consciousness as they progress towards puberty and may also be more vulnerable to teasing

    and bullying from peers. It is at this time that some children may try to hide their deficiency,

    particularly if they feel the effects of social stigma, even though may they have accepted the

    appearance of the arm/hand previously. There may, for the first time, be signs of resentment and

    a feeling of injustice about their disability. Again, however, there is little in the academic

    literature which highlights how adolescents with this presentation deal with issues of body image

    at this stage of the life span. Van Dorsten (2004) notes that no data exists to clarify whether body

    image issues are greater for individuals with congenital limb loss, or for persons with acquired

    limb loss arising from traumatic accident or vascular disease.

    Parental support at times of transition in a childs life is always important but it is likely to

    be crucial for the child who may have experienced various limb fittings (if prostheses are

    involved) surgical procedures and other therapeutic interventions, which call for them to develop

    adaptive coping styles. Biddiss et al (2007) highlight that strong social support networks

    consisting of parents, teachers, friends and classmates have a positive impact on the

    psychosocial health of children with disability. In fact peer acceptance of individuals with upper

    limb loss generally appears to be good for children and adults alike. In terms of personal

    adjustment and adaptation children with congenital limb loss have a higher level of social

    adjustment in contrast to adults with acquired upper extremity deficiencies. This may be

    attributed to the fact that persons with a congenital condition have a lifetime of incorporating their

    disability into their identity. Persons born with disabilities begin to shape meanings ascribed to

    19

  • 8/8/2019 Special Topics Paper 1 - For Merge

    20/38

    assistive technology early on and are more likely to consider it to be a means for facilitating

    performance of tasks which they might not otherwise be able to undertake. (Louise - Bender

    Pape et al, 2002). Those individuals with an acquired impairment, or amputation which has

    arisen from sudden trauma or a state of acute, or even progressive disease are likely to have to

    make more significant and critical changes in lifestyle, employment and social roles. In such

    instances the use of assistive aids and prostheses maybe viewed as an inadequate substitute

    and may not compensate for the loss of function of the limb and serve as a negative reminder of

    this for the individual. However there is evidence which suggests that upto 19% of adolescents

    with upper limb deficiencies are likely to reject prostheses and aids.

    There are a possible range of reasons for this. Postema et al (1999) and Biddess et al

    (2007) note that there is a shift in functional needs, from motor skills necessary for play and

    exploration, to cognitive skills at this stage of development which exact less extensive use of the

    hand, but more importantly if parents have negative expectations of their childs prosthesis then

    the likelihood of it being rejected is higher in this instance. Biddiss et al (2007) also note that for

    older pediatric users cosmesis has higher priority as a design feature than functional utility.

    Secondly, adolescents may negatively reassess the role of their prosthesis as they form a more

    autonomous identity. This is also a time when image counts for dating and appearance is tied in

    with self-worth. De Tonnacour and Shorgan (20004) note that grief for the absence of a perfect,

    symmetrical body can be intensely felt at this stage and can become an important element adding

    to the normal crisis of adolescence. Subsequently adolescents with a visible difference or

    disfigurement may be more susceptible to lowered sense of self worth which may turn to

    depression. (Rumsy and Harcourt, 2004). Louise- Bender Pape et al (2002) emphasize that the

    extent to which assistive technology and other devices are perceived as acceptable and helpful

    tools depends on the individuals point in the life cycle, their place and role within the family,

    cultural heritage and the social consequences of assistive technology use. Bad fitting

    experiences which have resulted in pain may also contribute to non-use of a prosthesis. (Carroll

    & Edelstein, 2006).

    Factors Affecting use of Assistive Technology Devices for the Upper Limb, with Specifc

    Reference to Prostheses

    Stoller (1998), states that in relation to human occupation assistive devices can be influential

    in a number of ways. Firstly, assistive devices and technology can facilitate the undertaking of

    tasks which may previously not have been possible. Furthermore, assistive devices can

    remediate or compensate for deficits in developmental skills with results of the individual being

    better able to organize existing skills into occupational behaviors which meet with societys

    expectations and the external demands of the environment. Additionally, assistive devices can

    significantly reduce the amount of time and effort expended in undertaking tasks which adds to

    efficiency and performance competence. However, assistive technology is not without its

    limitations and it is important for both the users and providers of assistive technology to have

    realistic expectations of what can be achieved. Although assistive technology can be a powerful

    remediation tool it may not always be feasible to apply it for effecting full restoration of lost

    functional capabilities. This is pertinent in relation to loss of function with the upper limb.

    Given the complexities and intricacies of the anatomical structures and physiology of the

    upper limb it is not possible to replicate all the movements of the natural hand and arm and any

    mechanical replacement is a poor imitation. Society in general, appears to be better at

    accommodating lowerlimb disability whereas there appear to be less environmental adaptations

    eg lever-type faucet handles, for those with upper-limb deficiency. There is also the issue of

    providing devices tailored to meeting the self-care needs of individuals with upper limb difficulties.

    Manufacturers may be deterred from committing funds and resources for improving components,

    materials, and investing in research for this relatively small but specialist market. (Carroll &

    Edelstein, 2006) However, the most widely available assistive technology devices available for

    21

  • 8/8/2019 Special Topics Paper 1 - For Merge

    22/38

  • 8/8/2019 Special Topics Paper 1 - For Merge

    23/38

    prescribed and accepted by individuals with a below elbow amputation. They have the

    advantages of requiring less natural energy being expended by the recipient, and the need

    for harnessing is reduced or eliminated but they are very costly. (Carroll & Edelstein,

    2006). However, they have the benefit of appearing more life-like and yield more grip

    strength when required for functional activities. (Herr et al. n.d)

    A Terminal device (TD) is the part of a prosthesis which substitutes for the anatomic hand.

    Many TDs are commercially manufactured and can easily be removed from or added to a

    prosthesis with a rapid disconnect wrist unit. Additionally by placing a rubber washer or O-ring

    on the threaded screw at the base of the TD, a user can gain better control over incremental

    rotation of the hand and this of benefit in sports such as baseball, basketball, or other recreational

    activities such as photography or the playing of musical instruments. Some units also allow two

    angles of wrist flexion to occur and this is benefit to anyone who cannot reach the midline of the

    body. Furthermore, wrist flexion is particularly essential for helping with feeding, dressing, oral

    and facial hygiene and toileting (Carroll & Edelstein, 2006).

    Future TDs are likely to incorporate sensory feedback. Long-term goals of present research

    in this area are to integrate prostheses directly into the bodys sensory nervous system and to

    design TDs which can replicate multiple grasp patterns and wrist movements. Additionally,

    electrodes may be implanted into muscle or attached directly and in conjunction with

    microprocessor technology the user may be able to select pre-programmed series of movements.

    For instance a person with a shoulder disarticulation could wear a prosthesis which is

    programmed for facilitating eating. The hand would hold a fork, whilst the wrist rotates and the

    elbow would flex to bring the food to the mouth with only one signal being required to trigger this

    sequence of movements. (Carroll & Edelstein, 2006)

    Brenner (2002) notes that electronic technology has made significant strides in the field of

    prosthetics but has subsequently led to increasing complexity and a greater range of options

    23

  • 8/8/2019 Special Topics Paper 1 - For Merge

    24/38

  • 8/8/2019 Special Topics Paper 1 - For Merge

    25/38

    Clinical funding is still a requirement to ensure that new or modified assistive technology

    aids and advices -prosthetics or otherwise - can actually be properly tested, applied and

    accessed by appropriate patient groups and evaluated for their efficacy as treatment techniques

    and for meeting the individual needs of users.

    Irrespective of these technological innovations, children as they develop, may opt to only

    use a prosthesis only for certain specific sporting activities or social events. Indeed some of the

    most popular adaptive and prosthetic designs have been developed by individuals who wanted to

    find better ways of participating in their favorite sports and recreational activities. The choice of a

    prosthetic aid depends on many factors which need to be assessed for by a clinical team.

    Principally these are in the domains of concordance, comfort of the device, particularly in relation

    to socket configuration, cosmesis and physiological and psychosocial factors of upper-limb

    disability as these are very pertinent to the issue of rejection of a device which tends to occur

    after one or two years of successful usage. Certainly an interesting and consistent finding in

    relation to adolescent prosthesis wearers is that they do opt to abandon use of prostheses at this

    stage of their life but there are few studies which have actively addressed the design priorities,

    and personal factors influencing device usage, of the pediatric and population via qualitative

    comments and reflective feedback (Biddiss, Beaton and Chau, 2007). More longitudinal

    research studies and methodological approaches which more readily incorporate service user

    opinion, for example focus groups could help bridge this limitation.

    Whatever the perspective of the team or level of advancement in technology, it is the

    childs wishes, where they are able to start expressing these, which should always be seen as

    paramount. Patience, compliance and participation are often increased with greater

    understanding but the best device in the world is of no use at all if a person does not engage with

    it (Carroll and Edelstein, 2006). Higher levels of prosthesis acceptance may be anticipated

    where the device is inexpensive to produce, lightweight and fit for purpose, biomechanically

    sound, durable and easy to repair or replace and cosmetically acceptable. As expectations of

    25

  • 8/8/2019 Special Topics Paper 1 - For Merge

    26/38

    technology grow, and patients become more informed of what might be available to them,

    providers of assistive devices, whether this is a prosthetist or indeed an occupational therapist,

    will need to stay abreast of new products and techniques.

    The Role of the Occupational Therapist with Adolescents with Upper Limb Difference

    In many respects the Occupational Therapist who works with adolescents with upper limb

    will, at varying times assume the roles of educator, advocate and researcher on behalf of the

    user. A key aim of intervention with this client group is to maximize function and autonomy,

    whilst also enhancing quality of life via the appropriate access to, and utilization of, assistive

    technology devices and aids. The therapist is likely to educate and train both parents and the

    adolescent about the strategies, techniques and equipment which might enable greater

    independence and efficiency of energy to be achieved regarding self-care activities such as

    feeding, toileting, grooming and dressing whilst also bearing in mind the developmental and

    physiological changes which may be occurring at particular times. (Celikyol,1984). Many

    children with congenital upper limb differences have, by the time they reach adolescence, learnt

    to use problem-solving strategies for carrying out essential activities of daily living and can be

    remarkably adaptable in most situations but consideration needs to be given to personal care,

    health, social, economic and leisure choices. This is particularly relevant for individuals who

    experience bilateral upper limb loss (Stoeker, 2004).

    Adolescent clients may prefer to adapt or modify how something can be accomplished

    rather than use equipment because this may reduce feelings of dependency. Mutual problem-

    solving which involves parents is keyas their attitudes, participation and interest shapes and

    influences training programs and treatment interventions. In fact there is likely to be lesser need

    26

  • 8/8/2019 Special Topics Paper 1 - For Merge

    27/38

    for specific interventions in many areas but the therapist may help adolescents and their families

    deal with specific personal, social and vocational effects of upper limb disability and issues which

    arise at times of transition. For instance these may include progression to high school, leaving

    home for the first time which brings expectations of being more independent of family, and

    obtaining employment.

    It is essential for the therapist to work collaboratively and holistically with the adolescent. In

    order to establish an occupational profile and design interventions which reflect their priorties and

    life situation the therapist should aim to use age-appropriate assessment instruments for

    gathering information, identifying the current strengths as well as potential problem areas.

    Appropriate assessments include the Adolescent Role Assessment (ARA), The Occupational

    Circumstances Assessment Interview Rating Scale (OCAIRS) and The School Setting

    Interview (Henry, 2003). The ARA is a semi-structured interview procedure which covers areas

    of childhood play, family and peer socialization, school functioning, occupational choice and

    anticipated worker role as an adult. The OCAIRS focuses more specifically on occupational

    participation and adaptation and addresses personal causation, values and goals, interests, roles,

    habits, and skills. The SSI can be used to identifying any unmet needs for school environment

    accommodations.

    In the context of working with adolescents with upper limb difference the therapist also

    needs to remain updated on the providers of assistive technology products, and to be aware of

    resources, agencies/organizations and latest developments which the client might need to be

    directed to in order to make informed choices about what is available and is going to best meet

    needs. At times, there may be the necessity for a client to make use of both simple and

    complex devices in order to meet functional needs and to satisfactorily undertake key everyday

    tasks. Artificial hands, Prostheses and individually designed orthoses are definitely examples of

    more complex devices but other widely available items can be utilized or adapted for domestic,

    self-care/personal and other instrumental life skills. However, where amputation is effected in

    27

  • 8/8/2019 Special Topics Paper 1 - For Merge

    28/38

    adolescence the occupational therapist is likely to have considerable involvement in providing

    instruction in the control and use of prosthetic devices. In relation to prosthetic controls training

    emphasis may be placed on body control motions, grasp/release and co-ordination of movements

    using a TD and in relation to wider prosthetic usage focus will be on activity based training

    pertaining to self-care, recreation and home, work or school evaluations as needed. (Carroll &

    Edelstein, 2006).

    To illustrate the range of assistive technology currently available, for assisting adolescents

    to maximize their ability to undertake basic personal/ self-care tasks and reduce the need for

    physical assistance from other, some appropriate devices, aids and techniques are now

    mentioned. Additionally assistive technology may be required to lend educational and vocational

    support for this group of adolescents as they transition to adulthood and some current advances

    in computer technology are also outlined in addition to reference to environmental controls .

    Devices for self-care and dressing - In the case of unilateral impairment, there may be

    reliance on use of the residual limb and the other fully functional limb for carrying out tasks

    mostly one-handed . For bilateral amputees feet may adeptly be used in place of the upper limb

    for many activities. Dressing can be made easier through use of items such as shoes with

    Velcro laces that can be closed with one hand, shirts/blouses with Velcro fastening instead of

    buttons or us of a PantClip (available from Sammons Preston) that can help unilateral upper-

    extremity amputees pull-up and button their own pants. Button loops/hooks can help upper

    extremity amputees more readily guide buttons through buttonholes and dressing sticks can also

    be used to position garments.

    For meeting grooming and hygiene needs commercially available dental floss holders can

    aid with dental hygiene and battery operated toothbrushes can be used by. Body/hair washing

    drying and brushing can be problematic but ingenuity, trial and error learning and perseverance

    are often factors which contribute to independent success in these areas. For instance showers

    can be adapted with Hygenic body washers (large rectangular pads that attach to the wall with

    28

  • 8/8/2019 Special Topics Paper 1 - For Merge

    29/38

    suction cups) and hair brushes can be strategically wall-mounted and brushed up against and

    hair-driers might similarly be wall-mounted. (Bowers, 2001).

    Toiletting for bilateral upper-extremity amputees can be challenging. Installed bidets for use

    with a commode can be useful in the home and there are more sophisticated, but also more

    expensive toilet systems, such as the Closomat which combines a water stream for cleansing and

    air for drying. The control handles can be manipulated using a mouth stick with a long metal

    hook (Bowers, 2001). However, physical assistance may sometimes be needed in some

    circumstances when the individual is away from the home environment.

    Feeding and Meal Preparation - Light-weight, combination knife and fork Cutlery sets (such

    as those available from Maddak,Inc) allow for one-handed users to utilize a single device for

    cutting and eating food. A device called The Eatery (also available from Maddak Inc) is also a

    relatively simple device that enables bilateral upper-extremity amputees to eat independently

    without using prostheses. At the other end of the spectrum switch activated systems such as the

    Winsford Feeder (available from Sammons Preston) which is operated by head or chin

    movements and brings a spoon from food to the mouth of the user, may be a means of helping

    individuals with no arms to eat independently. Being able to cook and make meals for oneself is

    an important life skill which adolescents may begin to experiment with prior to leaving home for

    the first time. For meal-preparation spiked cutting/chopping boards can be invaluable for one

    handed users and automatic can-openers such as the one touch can-opener can ease

    frustration of trying to open cans. Jars can be opened a variety of ways with modified techniques

    and devices. For instance a unilateral upper limb amputee who is fitted with a prosthesis can

    grasp the middle of the container with the terminal device and then use the sound hand to

    unscrew the lid. Alternatively if only one hand is being used, the jar can be secured with a piece

    of dycem under it, and then the hand pushes down on the lid and then turns it. There are other

    commercial aids to assist with this task, but are best being tried first wherever possible before

    being purchased to see if they work for the particular individual user.

    Technology for facilitating educational participation for Adolescents with Upper limb

    Differences

    In many instances there may not be the need to use specific complex technological or

    assistive devices with children with upper limb difference but this will depend upon the extent and

    type of presentation which will affect how the adolescent is able to participate in school activities.

    Some adolescents with unilateral limb loss may require only minor accommodations in the

    classroom which then enable them to fully engage with the curriculum. These students, may for

    example, be very capable of performing hand-writing tasks without specific remediation and can

    be proficient at one-handed typing, or using standard keyboards rather than requiring adapted

    versions. Likewise some students with bilateral limb absence, may be able to use writing

    instruments dexterously with their toes, but may not want to do so in front of their school peers,

    and so assistive devices and computer technology may be preferable and appropriate for

    increasing access to the learning environment for these students. Where prostheses and

    terminal devices are in use, they should enable the student to have functional grasp and strength

    for pencil and paper work, keyboarding and being able to hold and place items (such as

    backpacks, cans of soda) effectively. Any re - fittings occurring at this time are likely to include

    requests from both parents and the child for prostheses which combine cosmesis with function.

    (Ramdial, Wierzba, Kurtz and Hubbard, 1997) However, in addition to the personal preferences

    and skill levels of individuals, the technology required always needs to be based on assessment

    of needs, cost and training requirement considerations and what can realistically be provided in

    relation to facilitating inclusion and engagement for the student in question.

    Computers

    Computer technology can open up the world for individuals with upper limb absence and

    gives them access to a social life, information, support and even employment which becomes a

    major area of focus when adolescents are on the brink of leaving school and deciding what they

    become in their adult life. Some competence with computing skills is expected with most jobs

    30

  • 8/8/2019 Special Topics Paper 1 - For Merge

    31/38

    these days and personal computers are also used routinely for managing aspects of our everyday

    lives, such as online banking and shopping in addition to being a source of leisure activities, but

    for many people with no hands, or only one-hand, typing, using a keyboard and a mouse may be

    difficult. (Bowers, 2001) Major advances have been made in computer technology and many

    products have been developed which can allow computers to be operated totally hands-free

    (Bowers, 2001) . Such products include foot-controlled mouse consoles, or headmouse devices

    which are activated by movements of the users head. A sip/puff switch or software is used to

    perform the click function. Additionally, other integrated infrared/sound/touch switches can make

    it possible for users to operate numerous devices and software with just an eye blink or other type

    of body movement. Several speech recognition/ voice activated software packages (such as

    Dragon Speaking 9) are now also available for providing access to the internet and facilitating

    written applications on the computer.

    Electronic Aids for daily Living and Environmental Controls

    Electronic technology in rehabilitation has created further potential for increasing

    independence for individuals with upper limb loss in the form of environmental control. Through

    environmental control systems it is possible to operate for example lights, telephones, and

    televisions, in a living or work area by use of residual control motions to activate either

    microswitches, pneumatic switches or voice- controls. Mouth sticks, universal cuffs or

    splints/orthotics may assist with accessing the systems but may not always be appropriate or

    necessary. Before recommending any Electronic Aids for Daily Living (EADL) thorough

    evaluation should take into account all environments where the EADL will be used, access

    methods, feedback mechanisms and requirements, flexibility and regularity of use, installation

    and cost. (Bain, 2003).

    Driving Adaptations

    The ability to drive may be of importance to the adolescent at this time and can be a major

    asset for independence. The occupational therapist can give vital information and advice about

    31

    32/38

    possible vehicular modifications that can be made and can refer parents and the child to the

    appropriate agency responsible for carrying out driving evaluations. (Morrissey et al, 2001).

    Many individuals with upper limb deficiencies drive successfully and sometimes without

    adaptations being made to vehicles. This is easier when cars are automatic transmission.

    However, modifications can be made which may include spinning knob conversions being made

    to steering columns, and windshield wiper controls and signal indicators being foot-operated

    switches/pedals.

    Implications for Future Practice and the importance of Increasing Occupational Therapy

    training and Awareness of Assistive Technology applicable to Upper limb Loss

    This paper has explored an area of congenital physical disability which is generally

    unfamiliar to most occupational therapists unless they develop expertise in upper limb

    dysfunction. Whilst occupational therapists may at some points in their practice come into

    contact with the adult amputee population it has been highlighted that children born with upper

    limb loss are, by the very nature of the rarity but also complexity of their conditions, seldom seen

    routinely in occupational therapy clinical settings. Children with upper-limb deficiencies are

    usually managed long-term by specialist multi-disciplinary facilities which are equipped to

    address the numerous assessment and treatment considerations needing to be given to factors

    of age, effects of maturation on function and level of deficiency of the limb, possible surgical

    interventions, and psychosocial influences which can have a significant impact on body image,

    successful management of transitions, rehabilitation programs, and outcomes for positive

    occupational adaptation. A key aim of this paper was to investigate how adolescents with

    congenital upper limb limb loss utilize assistive technology in their everyday contexts with

    particular emphasis on managing self-care activities of daily living.

    At the beginning of the paper a number of questions were posed which appear not to

    have been addressed in mainstream occupational therapy journals or healthcare research

    32

  • 8/8/2019 Special Topics Paper 1 - For Merge

    33/38

    literature pertaining to the adolescent population with this type of upper limb deficit and their

    particular needs in this area of occupational performance. These questions were directed at

    establishing if current assistive technology options can fully meet functional requirements for

    activities of daily living and if they dont then what alternative strategies/techniques bridge the gap

    which could make a difference in these areas.

    There are numerous factors which shape personal preference choices for assistive

    technology and some of these have been described in this paper . Although overgeneralizations

    cannot be made about all adolescents who comprise this treatment population it has become

    apparent from undertaking this inquiry that there are usually two clear paths which teenagers

    with congenital upper limb deficiencies ultimately chose between. These are either the use of

    customized and functional myoelectric prostheses which can be adapted for purpose with

    differing terminal devices, or actual rejection of mechanical and complex devices in favor of

    problem-solving approaches and some utilization of simpler aids, modifications and

    environmental adaptations. With regards to the former, children whose deficiencies are terminal

    transverse, for example below- elbow or above elbow, and who have had early initial and

    successful fittings of prostheses as infants, at around 6 months of age, are good candidates

    (Wenner, 1995). In relation to the latter, rejection most often occurs where children are either

    bilateral amelic or phocomelic. If children with this level of deficiency are taught early on to use

    their feet as hand substitutes they develop a high level of prehension, strength, flexibility and

    sensibility and can accomplish most activities successfully and independently. Irrespective of

    whatever route is taken, it is most important that children with upper limb difference cultivate a

    strong self-identity and body image as they develop. Lack of this is acknowledged within the

    prosthetics literature to be a probable contributory factor for rejection of prostheses in

    adolescence but as yet has remained largely unexplored in research studies.

    Further research for gaining the service user-perspective for this group is pertinent.

    Unless it is known what these adolescents think themselves about the assistive technology

    33

  • 8/8/2019 Special Topics Paper 1 - For Merge

    34/38

    available and their relationships to it as active users and consumers, can occupational therapists,

    truly say that they are providing the best evidence-based practice, treatment interventions

    rehabilitative approaches, for this pediatric population?

    Biddiss & Chau (2007), comment that conducting good quantitative studies in this area is

    challenging because of the heterogeneous population characteristics and the difficulty of

    recruiting sufficiently sized populations on which to draw results. However, in relation to

    looking at the personal factors which shape use of assistive technology qualitative and descriptive

    research methods, such as case studies and in-depth interviews can be more appropriate for

    gaining insights and information about the lived experience.

    Healthcare professionals involved with considering the role of assistive technology for this

    client group need to stay informed and aware of the alternatives which most appropriately and

    beneficially meet needs. However, due to the infrequent nature of congenital upper limb loss

    there is a paucity of experienced clinicians whether prosthetists, physicians, therapists or

    psychologists with a depth of understanding of this area of pediatrics. Presently, occupational

    therapists in training receive little instruction in relation to assistive technology, biomechanics and

    specific upper-limb devices as they relate to the pediatric population. Although Occupational

    Therapy is crucial in the rehabilitation of amputees and other upper limb conditions most

    occupational therapy students seldom encounter children with the presentations described in

    this paper or prosthetic users during their fieldwork or training experiences. Post-qualification

    there appear to be limited opportunities for advancing theoretical knowledge and gaining practical

    competencies in this field. One or two-day intensive workshops being run at OT schools by

    OT practitioners specializing in this field and continuing education programs which address skills

    in this area would appear to be necessary in order to increase the knowledge base of therapists

    who may at some point encounter children with upper limb difference, outside of their usual

    arena of practice.

    In conclusion, this paper has highlighted the different means by which assistive technology

    can be an important adjunct to the facilitation of independence for those who experience differing

    degrees of upper extremity limb loss and the attendant limitations and physical dysfunction which

    can arise from this presentation. However, assistive technology should fit with the person

    rather than vice versa and ultimately decisions made as to how this is purposefully incorporated

    , into real life everyday contexts ultimately rest with the individual.
