AbstractPurpose. The aim of this study was to investigate the relationship between fatigue and communication in people with MS.Method. A phenomenological approach was used in in-depth interviews with 10 people with MS to gain insight into thelived experience of the interaction between MS fatigue and communication. Themes were derived from inductive analysis ofverbatim transcripts of the interviews.Results. Participants framed their observations around three major themes. In the first ‘revealing communication changes’an increase in the severity of communication symptoms and the onset of new communications symptoms when experiencingfatigue were reported. In the second ‘concealing and coping’ a range of covert and overt strategies employed to managefatigue and communication changes were described. Finally the complex interplay between symptoms of fatigue andcommunication, strategies employed to manage these symptoms and societal attitudes was reported in ‘barriers toparticipation’.Conclusions. Fatigue impacts on communication impairment, activity and participation. Self reports have an important roleto play in clinical assessment of fatigue and communication in MS. Multidisciplinary team input is vital for the effectivemanagement of clients with MS fatigue and communication change. Further research into the impact of fatigue on differentaspects of communication is required.
Keywords: Multiple sclerosis, fatigue, communication
Introduction
Multiple sclerosis (MS) is a demyelinating disease of
the central nervous system; between 52,000 and
62,000 people in total are estimated to live with MS
in England and Wales [1]. There is currently no cure
for MS and the life expectancy for the majority of
people with MS is not affected by this diagnosis [1].
Thus people with MS live with and manage their
symptoms for life.
Although speech disorder was included in the
original triad of symptoms identified by Charcot in
1877 [2], the communication impairments asso-
ciated with MS have only in more recent years
received detailed research attention. Dysarthria (a
motor speech impairment) is the most commonly
reported communication disorder affecting people
with MS [3], with reported prevalence varying
between 40% and 55% [3 – 6]. Reports vary regard-
ing the presence or absence of language disturbances
in MS. This may relate in part to the sensitivity of the
assessment batteries used to assess language dis-
turbance in MS [7]. Research has shown that with
sensitive assessment batteries some individuals with
MS do exhibit language difficulties such as naming
or providing definitions of words as well as difficul-
ties with cognitive communication tasks such as
problem solving or abstract reasoning [7 – 10].
In 1984, Freal et al. [11] published a seminal
article which drew attention to fatigue in MS,
indicating that 78% of their subjects reported
experiencing this symptom. Fatigue in MS differs
qualitatively and quantitatively from fatigue experi-
enced by healthy people. MS fatigue is usually
experienced daily, lasts up to six hours and worsens
in the afternoon [11]. It is a complex and subjective
symptom, described differently by individuals with
MS. This complexity is reflected in the plethora of

attempts to define it. The MS Council for Clinical
Practice Guidelines [12] define fatigue as ‘a sub-
jective lack of physical and/or mental energy that is
perceived by the individual or caregiver to interfere
with usual and desired activities’.
However, such general definitions have been
criticized, as people with MS tend to use the term
fatigue to refer to different types of symptoms.
Schwid et al. [13] advocate assessment of fatigue
by breaking it down into its component parts.
They detail means of quantitatively assessing
motor and cognitive fatigue, as well as the use of
visual analogue scales to report lassitude (defined
as ‘a subjective sense of reduced energy’).
However objective assessments of cognitive fatigue
or exercise-induced fatigue have not been found to
correlate with patients’ self reports of fatigue severity
[14,15].
It is acknowledged that MS fatigue is ‘one of the
most difficult symptoms to treat and understand’
[16]. Extensive attempts have been made to develop
a definitive description of fatigue, to understand the
pathophysiological cause of fatigue and to measure
the phenomena, but despite such work, it is widely
acknowledged that people with MS are living with
the consequences of fatigue which are far reaching
and pervade every part of their lives. Fatigue is
reported as the worst (14%) or one of the worst
(55%) symptoms of MS [17]. Fisk et al. [17] suggest
that ‘fatigue appears to be a distinct impairment
factor which, together with neurologic impairment,
plays a large role in determining the physical,
psychological and social handicaps that the MS
patient faces’. They found that 60% of their sample
reported worsening of cognitive, psychosocial and
physical symptoms when fatigued, and therefore
suggested that an assessment of fatigue is vital in
order to understand a patient’s presentation in
clinical assessment.
Referral of people with MS to Speech and
Language Therapy services is not always routine
[18] therefore communication impairments asso-
ciated with MS and the impact of fatigue on
communication impairments have not always re-
ceived focused clinical intervention or the compre-
hensive research required to underpin evidence
based practice. In addition the World Heath
Organization’s (WHO) International Classification
of Functioning, Disability and Health (ICF) [19]
urges clinicians to look beyond issues of impairment
to consider the impact of health conditions such as
MS on an individual at the levels of activity
(execution of tasks) and participation (involvement
in life situations). While such frameworks have been
used to discuss and report communication change
and interventions in a range of client groups [20,21]
little is know about communication activity or
participation in MS or the impact of fatigue on
levels of communication activity or participation.
Yorkston et al. [22] used interviews to report on
the insider’s experience of living with MS and
associated communication change. Whilst fatigue
was not the focus of this research, schema was
developed to summarize the various factors which
participants reported to impact on communicative
participation. These included impairment level
factors such as cognition, vision and notably fatigue.
The results emphasize the need for all clinicians to
explicitly recognize the influence of fatigue on a
range of impairment factors, and highlight the need
for Speech and Language Therapists (SLTs) to be
aware of the interplay between a range of impairment
factors, including fatigue, on any communication
activity.
The Multiple Sclerosis National Clinical Guide-
lines, (MSNCG) [1] suggests that ‘Each professional
in contact with a person with MS should consider
whether fatigue is a significant problem or a
contributing factor to their current clinical state’.
However the specific impact of fatigue on commu-
nication has not been comprehensively investigated.
Some studies have examined the impact of fatigue on
the speech production system in normal populations
[23 – 26]. Others have reported the muscles of
speech production to be subject to the impact of
fatigue in MS [27], or provided general reference to
the exacerbation of speech symptoms in MS with the
onset of fatigue [28]. However, few studies compre-
hensively report on the impact of fatigue on
communication in people with MS, or look beyond
its impact at the level of impairment to its impact on
communication activity or participation.
Hartelius et al. [29] reported on the relationship
between fatigue and communication in participants
with MS. They used the Fatigue Impact Scale (FIS),
a self-report questionnaire that attempts to measure
the impact of fatigue on activities of daily living.
However, the FIS does not address the impact of
fatigue on communication. Therefore they devised
an addition to the FIS, the Communication Scale
(CS), which consisted of 20 statements concerning
the impact of fatigue on communication. MS
participants reported significantly greater commu-
nication problems caused by fatigue than controls.
Interestingly in this study clinical assessment of
communication using standard language and
speech assessment batteries was not found to be
sensitive to the communication problems reported
by participants.
The importance of the insider’s experiences of MS
is now firmly established in the literature. The
outcomes of such research have been used to develop
an understanding of MS and to evaluate MS
clinical practices [22,30,31,32]. The results of such

qualitative studies have implications for interpreting
and understanding the experiences of people with the
condition and have the potential to influence clinical
management of symptoms. The expert, the person
with MS, has a role to play in the education of
clinicians and researchers. They can provide for us
valid and valuable insights into the lived experience
of fatigue and communication, which have the
potential to direct clinical assessment and interven-
tion and further research.
The purpose of this study was to explore and
understand the insider’s perspective of the impact of
fatigue on communication in MS; to highlight
relevant issues for clinical intervention and finally
to provide a focus for further research in fatigue and
communication in MS.
Method
This research was approved by the Office for
Research Ethics Committees in Northern Ireland.
Ten participants with a diagnosis of MS were
recruited in response to advertisements placed with
MS support organizations in N. Ireland. The
advertisement indicated that potential participants
should experience fatigue and communication
change which they associated with their diagnosis
of MS. They were invited to contact the researchers
by post, telephone or email. Participants were
required to be over 18 years old with, a confirmed
diagnosis of MS, capacity to provide informed
consent and ability to convey their opinions at
interview (e.g., use of speech, writing, or use of an
augmentative communication device), and as indi-
cated above, to report communication changes and
fatigue which they associated with their diagnosis of
MS. Potential participants were excluded if they had
any other neurological condition, serious illness or
significant hearing loss.
For participant details see Table I.
A phenomenological approach was used in
this study to discover the lived experiences of
individuals from their own unique perspective.
Such an approach was considered particularly useful
for deriving insights into symptoms such as fatigue
and communication, which are subjective in nature
and inseparable from the context in which they occur.
Interview One
Written consent was obtained for participation in the
research and audio-recording of the interview. Each
participant met with the first author twice. During
the first meeting fatigue was measured with admin-
istration of the Modified Fatigue Impact Scale
(MFIS). This is a 21-item self-report questionnaire
developed by the United States National Multiple
Sclerosis Society [33], which addresses the impact of
fatigue on physical, cognitive and psychosocial
functioning, (but has no specific reference to com-
munication). All items are scored so that higher
scores indicate a greater impact of fatigue on a
person’s activity; scores can range form 0 – 84.
Participants also described their major communica-
tion symptom(s) (see Table I), before being inter-
viewed regarding the impact of fatigue on
communication. Participants were reminded that
they could withdraw from the research at any time.
Nine of the ten participants chose to be interviewed in
their homes. At his request the tenth participant (CU)
was interviewed in a private office in his work place.
Interviews were used to facilitate the participants
to describe, without constraint, their unique experi-
ence and perspective. Interviews started with a
statement that the participant was viewed as the
expert in their unique condition. This was followed
with a review of the purpose of the interview. The
interview opened with the question: ‘Tell me in
detail about your experiences of communicating
when fatigued’. Questions and probes used during
the interview were open, neutral, and were used to
elicit in-depth descriptions of the participants’
experiences, and to clarify unclear points. For
example when a participant referred to a broad term
such as ‘being tired’ they were asked for clarification,
such as ‘tell me what you mean by ‘‘being tired’’’, or
‘tell me about a time when you were tired’, or ‘if I
was with you when you were tired what would I
notice?’. Thus participants were encouraged to give
examples to illustrate their experiences and feelings.
Questions were also used to guide the participant
back to the focus of the interview when they strayed
from the topic.
Data analysis
Interviews were transcribed, verbatim. Accuracy of the
transcripts was verified by random sampling of three
interviews. Each transcript was then read multiple
times in order to establish a sense of the whole
interview. This initial step was completed separately by
both authors. Next, key experiences referred to by the
participants were identified for example, ‘I knew what
I wanted to say but I just could not find the words’.
These were labelled meaning units. Code words were
attached to each meaning unit. The code words used
were concrete and descriptive of the ideas expressed in
the text, so for the example above, the code words
attached were ‘Word Retrieval Difficulty’. This second
level of analysis was completed separately by each of
the authors.
The next stage was completed collaboratively by
both authors and involved comparison and debate of
the meaning units. As these were debated and

discussed the meaning units were also clustered into
common categories or themes. Again in the example
above the theme which evolved was ‘revealing
communication change’.
Next, a summary of each participant’s transcript
was prepared. All meaning units relating to each
thematic heading were colour coded within the text
and then listed for each participant, thus establishing
an audit trail.
Further joint discussion then took place regarding
the themes. This involved returning to the original
transcripts, agreeing themes, and debating potential
blind spots of each of the researchers. Themes were
then updated to ensure that the essence of the
transcripts had been captured.
Interview Two
At interview two each individual participant’s origi-
nal written transcript was presented. Each high-
lighted meaning unit and its interpretation with
reference to the key themes was discussed. Partici-
pants had the opportunity to review how their words
had been interpreted ensuring that understanding
between the researcher and participant had occurred
[34]. Where interpretation of a meaning unit was
disputed participants were invited to elaborate. Their
elaboration or interpretation was recorded directly
onto the written transcript. For example at interview
one a participant discussed using written notes, at
interview two she clarified that this was a covert
strategy not widely know to people in her environ-
ment. Thus it was linked to the covert strategies
thematic heading. After interview two, any altera-
tions to the links between meaning units and
thematic headings were updated on the summary of
each participant’s transcript.
Results
Participants framed their observations regarding
communication and fatigue around three major
themes, revealing communication changes, conceal-
ing and coping and finally barriers to participation.
Revealing communication changes
The first theme described variability in communica-
tion symptoms, which participants attributed to the
impact of fatigue. Fatigue was reported to exacerbate
communication symptoms and also to result in new
communication symptoms becoming apparent. De-
scriptions reflected an acute awareness of the specific
communication impairments impacted by fatigue.
The impact of fatigue was to unmask communication
symptoms and so reveal communication impairment
to listeners.
Fatigue increases the frequency and severity
of communication symptoms
Participants reported increases in the frequency or
severity of cognitive communication symptoms,
language-processing deficits and/or motor speech
symptoms (see Table I for details) with the onset of
fatigue.
MO described the differences in her cognitive and
language skills with and without fatigue:
My memory’s much better first thing in the morning
before the fatigue really hits me and I’d say my speech is
much better . . . . Saying the wrong word, but I do that at
the best of times. Yeah, but the more fatigued I get, the
worse, the worse I would get. Yes, definitely, I would
still . . . I might be going to say car and I could say door.
But it would be worse when I am fatigued.
EN noted that her speech became more slurred with
fatigue:
If I was really tired, I would be really slurred . . . you
would nearly think I was drunk.
US also noted that her speech was the symptom of
her condition most sensitive to fatigue:
Sometimes I can slur words, you know. I have noticed
that and maybe sort of four o’clock to six or seven
o’clock say, I’ll slur words, you know. I’ll sound like I’ve
had a few to drink and I haven’t! But I talk like this
[referencing her mild dysarthria at the time of interview]
most of the time, but just . . . sometimes . . . when I must
be tired or something, my speech starts to go down,
yeah. Yeah. And that would be the one thing that you
would . . . one symptom you would notice, or I would
notice, you know? My speech would be sort of laboured
at that time.
New communication symptoms become apparent
Half of the participants reported the onset of new
communication symptoms which they were aware of
only when experiencing fatigue, these included both
language processing difficulties and dysarthria.
Common to all five was the onset of dysarthria (see
Table I).
MO reported an increase in the severity of her
cognitive and language impairments with the onset of
fatigue (above) but also reported the onset of a new
symptom, dysarthria, which she experienced only
when fatigued:
But slurring is a different thing. When I’m tired . . . when
I’m really tired . . . my speech gets really slurred. And
later on in the day, if I don’t get my rest, the worse I get.

Listeners become more aware of communication
symptoms
Participants described how the interplay between
fatigue and communication led to communication
symptoms becoming more apparent to listeners. They
reported that the resulting communication did not
reflect how they would like to represent themselves.
CU (who reported experiencing communication
symptoms only when fatigued) described how fatigue
impacted on communication skills at work making it
difficult for him to present his true meaning and
feelings:
It can be quite an effort. At times I feel like, I’d rather go
away and sit down or read a book or just sleep, but
getting through it . . . because you can’t get the word you
want and you use simple words, it reduces the impact of
what you’re saying and when you can’t use the word you
want and you use baby words for it, you’re not getting
your true meaning or feeling across.
Common to all participants was some reference
to listeners’ perceptions of them as drunk or lazy
or the need to protect themselves from such an
interpretation. NC described the frustration around
trying to communicate with her daughter during a
period of fatigue.
. . . is it like a drunken slur you get when you’re tired? I
remember one night, I was really quite angry . . . and she
was only joking, and she said, ‘Have you been on the
bottle?’ and, I mean, she was only having a laugh with
me but I thought, if you only knew! – I really was slurred
that evening. I really was very, very tired that evening
and I could feel, as you were talking, you could feel that
one word was slipping into the next word.
TW described how she felt her speech betrayed her
attempt to present herself as able and competent:
Well, how your speech sounds. I mean, to look, you
wouldn’t think there’s much wrong with you, because
people always say, ‘And you look so well!’ but it’s not
that, it’s when you open your mouth and try to talk.
Communication is a sensitive gauge of level of fatigue
Participants also reported that familiar listeners used
the participants’ voice and communication as a
gauge of their level of fatigue.
GG reported that his speech was noted by friends
and family to be susceptible to fatigue:
. . . anyone that knows me says, ‘Your speech is a wee bit
(down) there, it’s slow or slightly slurred’. They’ll just
say, ‘you sound very tired’.
MO and EN similarly reported how listeners use
communication as a sensitive indicator of levels of
fatigue.
Well, people have told me, maybe when I’m speaking on
the phone . . . they’ve said my speech gets very slurred
when I’m tired . . . they would say . . . they would know I
was tired because my speech would have got very slurred. I
might not even have been aware of it. It was a friend of
mine was on the phone one day and she said, ‘You must
be tired, your speech has got very slurred’. (MO)
My eldest daughter, if she phoned, you know, she would
say, ‘You’re exhausted, I know by your voice’. (EN)
Concealing and coping
In the second theme concealing and coping strategies
were reported to operate on two levels. Firstly covert
strategies were employed behind the scenes, and
operated to keep interactions looking as normal as
possible on the surface, without the need to openly
acknowledge any underlying impairment. Partici-
pants themselves took responsibility and ownership
of such strategies. On a second level overt strategies
were used in collaboration with interlocutors to
achieve successful outcomes in communication
activities.
Working behind the scenes/covert strategies
Common to all participants was the enormous effort
and pre-planning that remains hidden from commu-
nication partners. Planning behind the scenes included
consideration of problems such as word finding and
memory difficulties. However, in common these plans
and strategies were covert or hidden from partners and
were concerned with keeping interactions operating as
normally as possible on the surface.
The two participants in employment (CU and
MC) noted that they used a range of behind-the-
scenes strategies in the work context to prevent their
communication symptoms becoming apparent. MC
described how she had developed a crib sheet of
potential phrases for standard letters to compensate
for her word retrieval problems at work:
. . . because I’m maybe writing to a mortgage company
and you have to phrase it in a certain way, and I would
maybe be sitting at my desk and I just can’t think . . . you
know, it’s ‘an agreement in principle’, you know, and it
just won’t come to me, and you know, but because I’ve
got now a big list on the computer. No, nobody would
know, but I always sort of think, ‘what is that word?’,
you know, ‘what is that phrase I’m meant to use?’ and I
go to my list and I sort of go down it until I get the
one . . . and it clicks, you know, once I see it, I know what
it is.

MC emphasized the fact that no one at work was
aware of the strategies she was employing:
I mean, my boss wouldn’t even know that I have it
there . . . nobody would know even know that I was
doing that.
Similarly in preparation for teaching CU noted
that he put material on overhead slides so that he had
a prompt or cue for recalling words, and also noted
that his meticulous planning meant that he had not
had to explicitly acknowledge his communication
symptoms at work.
By the way [laughs], there’s nobody over at my college, I
don’t think, that has twigged on to this yet.
Behind-the-scenes preparations were not re-
stricted to the workplace, but were consistently
employed across contexts and participants. MO
described a similar circumstance involving pre-
planning for a visit to her physician:
I would have to write it down to make sure that I would
remember what I was going to say, you know? Because I
might not ask the right questions . . . or give the right
answers.
Again MO referred to the fact that this effort
remains hidden from potential listeners:
There’s a lot of planning going on there that nobody is
aware of. Even the people living with you don’t realize it.
Preplanning of communication activities related
not only to what might be considered purely
communication symptoms. Participants described
considerable effort put into preparing a setting
conducive to communication, attempting to control
as many variables as possible in order to reduce
distractions or complications. CU referred to having
to think first about practicalities so that he could
make himself available for communication:
One strategy is, if you know you’re going somewhere and
you know you’re going to be there about an hour, go to
the toilet! You’ve got to make sure you’re not called away
when you’re there, if I’m going anywhere, I sort of work
out what I’ve got to do so that I don’t get embarrassed.
Overt coping strategies
Participants reported on a wide range of overt coping
strategies employed to manage their fatigue and
communication changes and so promote success-
ful communication activity. In contrast to covert
strategies, they were openly acknowledged and often
required collaboration in order to be successful.
Energy efficiency
The onset of fatigue was reported in the first theme
(revealing communication changes) to increase the
range and severity of communication symptoms
experienced. In this context energy efficiency strate-
gies were described by all participants as a means of
managing fatigue and the associated communication
changes.
Reduce activity. Participants reported that one coping
strategy was reduction in their overall activity level.
CU reported that he had reduced his working hours
in order to cope with his fatigue and communication
changes:
One of the things; I don’t work past 1 o’clock in this place.
Others reported on the importance of targeted
activity TW:
Well, I would be inclined to be a lot quieter and would
only talk when I needed to.
Schedule activity. Participants reported schedul-
ing activity over the course of the day or week in
order to successfully engage in or complete activities.
MO said:
Well, I try not to be doing anything in the evening time
because I’m too tired. It would either have to be in the
morning or early afternoon.
All participants referred to the importance of rest
periods built into the daily routine. CU said:
. . .but when I get home, I’d be going home about one
o’clock today probably . . . when I make it home, there’ll
be nobody in the house so I can sit. What I will
do . . . what I do is I lie down and sleep for maybe an
hour or so, get some energy going.
Humour
Humour was reported as a positive coping strategy
and was frequently employed when communication
impairment was apparent. It was used as a means of
acknowledging the communication symptom while
allowing conversation and activity to move on while
preventing discord with the listener.
Now, I was in the Post Office on Monday . . . I meant to
say to the girl, ‘Thanks very much’ but it came
out . . . and I can’t remember what way it came out . . .
but it came out all jumbled, and I just smiled and she
smiled back! [laughs]. . . So if I make a blunder on the
phone, you know, I laugh it off, you know, whoever I’m
talking to. (EN)

Similarly NC and TW reported how humour was
used within the family to allow communication
impairments to be acknowledged in a non-threaten-
ing way.
My youngest daughter, she would laugh with me, you
know, she would come in and say ‘oh, are we talking like
this today?’. (TW)
Similarly NC described how her family used
charade actions in a joke to negotiate meaning when
her speech was slurred:
and it used to be the joke with my husband and my son
and daughter, and they’d be saying [mimes charades]
doing this sort of thing.
Explain, acknowledge, educate
The group fell into two camps regarding the value of
explicitly acknowledging and explaining their MS
symptoms. Some participants felt that openly
acknowledging their symptoms was important and
that they had an important role to play in the
education of the public. TW said:
I would explain that I have MS and my speech is
affected.
Similarly, GG said:
It’s just a matter of letting them know that . . . not to be
afraid, that in the majority of cases that they’ll be dealing
with are not contagious [laughs] and, as usual, the main
point to get across is that people with a disability have a
right to expect the same rights and dignity and treatment
as anybody else, you know.
But on the other hand, some participants while
they wanted to protect themselves from the potential
misperceptions of the listeners also felt that they did
not owe the listeners any explanation.
I don’t let it bother me, you know . . . if . . . if . . . if the
other person looks at me funny, I’ll go to myself well,
that’s your problem . . . . I’m not going to stand and
explain what’s wrong with me. Well that’s their problem
if they think I’m not right in the head. (EN)
Notes for communication and memory
Written notes were described above as a covert
strategy, used to manage communication and mem-
ory difficulties. They were used behind the scenes, to
pre-plan and so in some instances, to prevent
communication symptoms coming to the fore.
However, notes were also employed explicitly by
eight of the ten participants to aid communication
and memory in an explicit way. In this context notes
were viewed as an extension of normal note taking
and written recording was carried out openly. The
two participants who did not refer to this strategy did
not have sufficient hand control for writing.
KT said:
What I do actually, at the kitchen table where I sit a lot, I
keep a pencil and paper in front of me and write things
down or else I just forget them.
Similarly NC said:
I keep a pad beside my bed and I write down things that
I wanted to say or maybe I was talking on the phone –
just somebody’s name or whatever.
Barriers to participation
In the final theme participants described barriers to
communication participation. While participants
reported barriers to be, in part, related to the
symptoms and strategies reported in the first two
themes, barriers were not perceived to directly result
from any single MS impairment such as fatigue or
communication. Barriers were the outcome of a
complex interplay between the range of impairments
experienced by an individual, the coping strategies
employed and people’s attitudes.
CU described how casual opportunities to socia-
lize could not be capitalized on due to the interplay
between impairments:
When I was coming along here, down the corridor,
another lecturer came along that I hadn’t seen in ages
and he started walking with me, and the thing is that
walking and talking is difficult. If I’m going anywhere
walking, I prefer to be on my own, so that I’m not
speaking to anybody. So really, every step I take, I’m
thinking about it but when I’m trying to speak at the
same time . . . I’m more than likely to trip.
All participants reported how their social circle had
become depleted since their diagnosis, and so the
opportunities for communication had become redu-
ced. Participants related this depletion in their social
opportunities due, in part, to the barriers created by
the attitudes and anxieties of those around them relat-
ing to confronting or dealing with MS and disability.
TW said:
It would be strangers or outsiders; they would be
inclined to talk to whoever is with you.
TW also discussed how family members’ embarrass-
ment acts as a barrier to participating in social
outings:

Well, my mother’s aspect of it would be . . . I had actually
two weddings to go to. I had one in June and one if
August and my mother would say, ‘Oh well, I hope your
speech comes back’, you know? In other words, you
don’t want to be going and talking like that and then I
just say, ‘Well, whether it comes or whether it doesn’t,
I’m still going’, you know?
Discussion
In the first theme, revealing communication changes,
participants provided detailed and cogent descriptions
of communication change and the interplay between
fatigue and communication. They reported an in-
crease in the frequency/severity of communication
symptoms with the onset of fatigue, and the onset of
new communication symptoms which were only
apparent during periods of fatigue. Participants
described a differential sensitivity to fatigue across
cognitive, language and motor domains of commu-
nication. Dysarthria was common to all participants
who reported the onset of new communication
symptoms when experiencing fatigue.
The detailed descriptions provided by participants
are arguably more useful than communication
assessment batteries which have been shown to lack
sensitivity to the subtle impairments associated with
MS [7,32] and which fail to consider the interplay
between fatigue and communication, and than
fatigue assessment tools which make no specific
reference to communication.
The differential in communication presentation
related to fatigue means that communication assess-
ment at times of fatigue versus assessment at times of
no or low fatigue, potentially results in different
clinical presentation, different clinical diagnosis of
communication symptoms and different severity
ratings of communication symptoms. Such fatigue
induced variability in communication may along
with, reliance on insensitive assessment tools, con-
tribute to the varied reports of incidence and
prevalence of communication impairments in MS.
Further research is required to examine the impact of
fatigue across communication domains. The results
of such research have the potential to provide
insights into the pathophysiological cause of MS
fatigue.
Self reports in this study described in detail the
individual’s experience of communication change
which covered issues of impairment, activity and
participation. Thus, self reports provide a more
comprehensive picture of communication than any
single clinical assessment battery currently delivers.
The MSNCG [1] suggest that professionals need to
improve their ‘acknowledgement that people with
MS have expertise and have views that should be
taken into account’. In the context of MS fatigue,
clinicians may comply with this guidance by giving
self reports of communication symptoms a more
prominent role in clinical assessment.
While clinicians are experienced in probing the
impact of factors such as relapse or remission or
neurological involvement on variability in presenta-
tion of symptoms, probing the impact of fatigue in
clinical assessment needs to become routine. There-
fore a clinical assessment tool to guide clinicians
through an assessment of the impact of fatigue on
communication would be a valuable resource.
However, in the absence of a comprehensive tool
Table II poses probe questions relating to the themes
which emerged from the participants’ transcripts.
These probes could be used as a starting point in
order to elicit self reports on pertinent fatigue and
communication issues. This may be of particular
value where the client experiences communication
and or fatigue problems but, as reported in the
second theme, works strenuously to keep those
symptoms hidden from friends, family and profes-
sionals. Since it has been reported that clients with
MS are not always routinely referred to SLT services
[18] such guide questions may be useful for a range
of rehabilitation professionals. Those who are reg-
ularly in contact with these clients or who deliver
regular reviews could use the response to such
questions to facilitate appropriate referral for symp-
toms which may remain covert during routine
clinical examination.
In other client groups presenting with commu-
nication problems, such as aphasia, it has been
reported that compensatory strategies developed by
patients themselves not those ‘trained’ by the SLT,
tend to be employed most frequently [35]. In the
second theme participants reported on a range of
strategies which they had developed to deal with the
impact of fatigue and communication changes.
These strategies included the use of energy efficiency
strategies and humour. However, recent reviews of
impairment and interaction strategies to deal with
motor speech and language processing symptoms
associated with MS [36,37] do not focus on such
strategies. Instead the strategies recommended by
SLTs typically focus on language processing, repair-
ing communication breakdown, the interlocutor
skills or the communicative environment. In view
of the impact of fatigue on severity and onset of
communication symptoms reported in this study,
clinicians can learn from the experts with MS, who
suggest that focusing on fatigue and how it impacts
on communication is an effective strategy to impact
on every day communication.
At present no medicines have been identified that
are recommended to specifically target fatigue in
MS [1]. However, fatigue management programmes
are gaining increased popularity as a means of

addressing fatigue with this client group. Such
programmes tend to be based on energy conserva-
tion principles and are frequently run by MS
specialist nurses and Occupational Therapists
[28,38,39,40]. While participants in the current
study reported on the impact of energy conservation
strategies on communication, reports in the litera-
ture of the outcomes of such programmes rarely
make specific reference to their impact on commu-
nication. Further research is required to determine
the specific impact of fatigue management pro-
grammes on communication and in particular their
impact on communication symptoms that come to
the fore only at times of fatigue. Given the
complexity of the communication impairments
associated with MS and the lack of sensitivity of
standard communication assessment tools to com-
munication problems associated with MS, the SLT
would be a key member of the team to involve in
such evaluations.
The World Health Organization [19] urges
healthcare professionals to intervene at levels
beyond impairment, to examine the context of
activities and to promote participation. Participants
in this study were asked to focus on fatigue and
communication but through their interviews urged
us to look beyond impairment issues drawing our
attention in the third theme to the need to focus on
barriers to communication participation. Barriers
related to complex interactions between impair-
ments, coping strategies and attitudes to disability
prevalent in society which when combined lead to
reduced opportunities for communication participa-
tion. Thus, reported barriers to communication
participation often included a range of factors such
as fatigue, mobility, and family attitudes which at
first glance are not the traditional domain of the
SLT or indeed of any single rehabilitation profes-
sional. Crayton et al. [41,42] refer to a cycle of
interrelated symptoms, where untreated symptoms
lead to increases in other symptoms. They suggest
that a ‘comprehensive integrated therapy model
offers the greatest opportunity for success in
addressing quality of life issues for patients with
MS’ [42]. Such an approach emphasizes the
importance of multidisciplinary management of
people with MS. The MSNCG [1] include the
SLT as a key member of the specialist team
required to address the needs of MS patients.
However, while clinical practice often sees the SLT
contributing to specialists teams, frequently they do
not have the opportunity to work as a full time
integrated member of the team where complex
issues and interplays between symptoms such as
those reported by the participants in this study can
be effectively addressed.
