Touching lives, making an impact

"Be the legend", the motto of the Hong Kong EastAsian Games (EAG) 2009, has been the spirit of thegames. The Hong Kong team finished the EAG with flying colours and our athletes have written a newpage in history, winning a total of 110 medals, 26 of which were gold. But as well as this tribute toour athletes, we should also note the hard work donebehind the scenes by the various supporting teams,including a group of sports physiotherapists andphysiotherapy students from the Hong KongPolytechnic University (PolyU).

In response to the request from the HomeAffairs Bureau to our Faculty requesting on-fieldphysiotherapy support to the badminton, tennis,hockey, volleyball and rugby sevens teams at theEAG, we formed a support team for these events.Thanks to backup from the Hong Kong PhysiotherapyAssociation, who provided personnel, and financialsupport from our Faculty as well as from the HongKong Jockey Club Sports Medicine and the Health SciencesResearch Centre, we recruited 44 experienced sports

physiotherapists and 120 undergraduate physiotherapy studentsfor the Games. Thanks must go to Quentin Yau, Elton Ng, Chris Chan, Eric Chow and Billy Cheung for liaising with the physiotherapists, and Shirley Fong for supporting the studenthelpers. Their effective coordination, efficiency in responding to contingencies and thoroughness in following up the matchesthroughout the entire EAG was a key factor in our success in providing the on-field physiotherapy service. Even though not all the athletes used our services throughout the EAG, ourpresence was certainly visible and appreciated. The rapport webuilt with the teams and our demonstration of professionalismwill be pivotal in securing our role in the sports arena.

The EAG have come to a successful conclusion, and weare proud to have been a part of the legend. The flame of theGames might have departed, but its light and heat is still felt inmany of our hearts. May both persist in our society, and may thelegacy of the EAG be the beginning of another legend for HK inthe years to come.

Building on their successful collaboration in theEAG, the Faculty of Health and Social Sciences (FHSS)of the PolyU has extended its association with theJudo Association of Hong Kong, China (JAHKC) asannounced on 13 January 2010.

Judo has been identified by the SportsCommission as an up-and-coming sport. TheDepartment of Rehabilitation Sciences (RS) in FHSSsent a team of professional experts including Dr AmyFu, Assistant Professor, and Miss Phoebe Cheuk,Clinical Associate and Sports Physiotherapist, to helpthe HK Judoists to clinch one gold and one bronzemedal in the EAG. As invited by the JAHKC, ourDepartment will continue to provide professional consultation and advice to identify elite athletes aswell as assist them to prepare for the 16th AsianGames to be held in Guangzhou in November 2010.

In the coming months, a team of physiotherapy professionals from our Departmentwill continue to conduct a series of scientific andsport-specific assessments of athletes. This will focuson a Judo-specific comprehensive musculoskeletal assessment, including but not limited to the evaluation of shoulder IR and ER strength and tests of flexibility, lower limb power and core stability. These arebased on the clinical evidence that Judo requires its

practitioners to have speedy reactions, explosive power andmuscular endurance over a five-minute, highly intensivecompetitive encounter.

The aim of this musculoskeletal screening is toidentify physical deficiencies and formulate an individualized

injury prevention and performanceenhancement programme for each of the elite HK Judo athletes. Each will be closely monitored.Injury prevention, acute injury management and rehabilitationwill also be implemented as needed during the preparationphase. From the start of thescreening to the end of the preparation phase, all steps takenare important in assisting the athletes to maximize their potential to achieve the best possible performance at the Asian Games. This is a comprehensive programme tailor-made for the competitors in Judo, and we hope to help our HK Judoists to continue thelegend in the forthcoming Asian Games.

The Hong Kong Occupational TherapySymposium 2010

Dr Kenneth Fong (Assistant Professor and Chairman of the Scientific CommitteeHong Kong Occupational Therapy Symposium 2010 )

This symposium was the most worthwhile and successful event for the occupational therapy (OT) profession in the year 2010, or indeed ever - particularly as it broke the record for the number of participants over thepast decade. Held on 30th January 2010 in the Hong KongPolytechnic University (PolyU), the event was organized bythe Hong Kong Occupational Therapy Association (HKOTA) in partnership with the Department ofRehabilitation Sciences of PolyU.

Health care in Hong Kong (HK)has undergone a steady shift and nowfocuses principally on the promotion ofhealth and healthy lifestyles, and the prevention of disabilities. Primary healthcare has rapidly gained public attentionever since the government put it on theagenda in the health care reforms of twoyears ago. Since then, occupational therapists have increasingly been asked to move beyond their traditional hospital-based roles and work in community or primary care settings.Responding to this trend, the theme of this symposium was "New Frontiers ofOccupational Therapy in Primary HealthCare and Community Rehabilitation". As aprofession which focuses on the wellbeingof people with disabilities, the Hong Kong OccupationalTherapy Symposium 2010 allowed our colleagues to presenttheir work of the past two years and demonstrate their success and efforts as health agents.

Fifty-eight abstracts, in the physical, psychosocialand paediatric fields, were submitted to the conference and 43 were accepted for oral presentation. Of the record-breaking 300 delegates, 36 were from the Philippines(University of the Philippines, University of Santo Tomas andthe Cebu Doctors' University), 5 from Japan (the TrainingCentre for Disabled Children of Urayasu and the SaitamaPrefectural University), and a few from each of the mainland,Macau and Singapore. A further 60 OT students were recruited as helpers. Moreover, we were glad to haveProfessors of OT, Gary Kielhofner and Renee Taylor, both ofthe University of Illinois at Chicago (UIC) as our invitedguests to set out their vision for developing primary health

care, particularly in terms of psychosocial practice. Bothspeakers are known for their work in developing the knowledge base in IT. Professor Keilhofner is particularlywell-known to OTs worldwide, having developed the Model of Human Occupation (MOHO), one of the most important theoretical frameworks in OT, in the 1980s and early 1990s.The anniversary dinner of the HKOTA was also held

immediately after the symposium with over 90 guests,including the Honourable Dr York Chow, Secretary for Foodand Health of the Government of the HK SpecialAdministrative Region (HKSAR).

The symposium also incorporated a discussionforum in which several well-known occupational therapists,who are also stakeholders in the government and NGOs,were invited to share their views on the direction and development of OT in different primary care sectors. For now, with increasing attention on how we can reduce theincidence of disease and injury in the general public bymeans of health promotion and protection, OTs may be looking to a new role in health promotion programmes, especially educational programmes for seniors and community activities for people with chronic disease.

The topic of client-centred practice has becomeincreasingly important in OT. Nevertheless, in our

Enhancing our Leading Edges

At the beginning of 2010, our Department held a retreat at theClearwater Bay Golf and Country Club, withthe theme "Enhancing our LeadingEdges". Not only was this held in a placewith breathtaking views, overlooking theClearwater Bay, but it also started with alist of breathtaking questions: "How manystaff's English first name starts with 'S'?Name 4 of them"; "How many PT and OTare there in the Rehab Clinic? Name all ofthem"; "Name the staff member who is going to receive theLong Service Award this year". Laughter as well as thoughtfullooks filled the room as we sought the answers from each other.

After this warm-up brainstorming activity, every one ofus was ready for the more serious business including discussionsrelated to the departmental review, postgraduate education andresearch development. There was a lot of insightful sharing anddiscussion of these topics.

On the afternoon of the first day, Associate VicePresident, Professor Judy Tsui, shared with us the University'sstrategic direction on Internationalization and brought us goodnews about the number of international students we could enrol

in the coming academic year. Mrs WinnieEley, Director of the International AffairsOffice, enlightened us on the scope of thesupport the University offers to realizethe goal of Internationalization. Winniealso joined in our subsequent discussionsand further clarified the support availablefrom the University.

As well as these serious discussions, we also held a teambuildingactivity to strengthen our team spirit.

"Looker", "Runner" and "Builder" - each one of us played one ofthese roles in a creative teambuilding activity. The rebuilding of amodel that resembled the original depended on the 3Cs - com-munication, cooperation and comprehension. Yet, the secrets ofsuccess seemed to be associated with the presence of heavy-weight (that is, influential) people in the team.

One of the highlights of the retreat was the conceptionof the "Dragon" programme plan, which vividly summed up the discussions regarding the integration and progression of thedifferent levels of academic program.

The retreat ended with a delicious seafood dinner in acosy local restaurant.

On December 17th 2009, we had our annual OccupationalTherapy (OT) mini-retreat at the CEO club on our PolyU campus. OT faculty members shared theirthoughts and ideas aboutcollaboration with universities in mainlandChina and the developmentof our existing OTpostgraduate programmesin the future.

One of the highlights of the discussionwas the new strategies andinitiatives on modes ofteaching such as blendedlearning, block teaching onweekends, an interactivelearning platform and ateleconferencing clinical teaching module. A postgraduateprogramme in Mental Health was proposed with a broader

Occupational Therapy Mini-Retreat2009-2010

scope covering crisis intervention in the family and alternative medicine using traditional Chinese techniques,

hypnosis and Qi-gong. In addition,

many of our dedicatedfaculty membersshared their personalexperiences andvisions in collaboration withmainland partnerssuch as the ChinaRehabilitationResearch Centre inBeijing, the FuijianUniversity of TCM, theKunming MedicalUniversity, theSichuan University,

the Sun Yat-Sen University and lastly, but not least, theDeyang Project in conjunction with the HK Red Cross.

Fall Prevention Programme for Older Peoplewith DiabetesIt has been estimated that 10% of the general HK population suffers from diabetes, with a prevalence of over20% in people aged 65 or above. Our earlier research hasfound that the muscle strength and tactile sensation of thefoot region in people with diabetes are significantly reducedwhen compared to age-matched control subjects. We alsofound that the soft tissue of the foot-ankle complex hadthickened, and the plantar soft tissue was significantly stiffened, in people with diabetes. Due to sensory and motordeficits, plus altered biomechanics in the foot-ankle region,this group of clients is prone to poor postural control andthus has an increased risk of falling.

A community based project entitled "Evidence-Based Community Fall Prevention Programme for OlderPeople with Diabetes" will shortly be launched with the

support of the Food and Health Bureau of the HKSARGovernment. This project aims to set up a specific exerciseprogramme targeting fall prevention for people with diabetesin HK. Participants will be recruited from the community.They will receive balance training, attend educational talksand benefit from a home assessment conducted by a registered physiotherapist.

On completion of this exercise programme, participants are expected to have improved muscle strength,flexibility and coordination, all of which can subsequentlyimprove their balance control. In particular, our health education and exercise training focus on fall prevention. Wehope this programme can encourage participants to build upa daily exercise habit and promote a healthy lifestyle in orderto prevent further complications.

professional lives it is often difficult to articulate what thismeans. Client-centred practice can be achieved across all OT sectors despite the different characteristics, outlooks,impairments and life circumstances experienced by clients.Over 56 participants registered for the pre-symposium workshop, "Achieving True Client-Centred Practice", conducted by Professors Kielhofner and Taylor. This workshop made use of multiple case studies covering various therapy circumstances, to illustrate how to achieveclient-centred practice at all times. Furthermore, 25 participants attended the 2 half-day post-symposium workshops on the evidence-based practice of health Qigong,and OT in health promotion: strategies and practice, both ofwhich were lectured by local experts.

Student's Activities

Clinical Placement in CANADA forPhysiotherapy StudentsWe are glad that we were granted this valuable opportunity to have our placement in Canada for six weeks. It was an enjoyable and unforgettable experience for both of us.We worked in two differentsettings: the PhysiotherapyOutpatient Services of theSt. Mary's of the LakeHospital and the PhysicalTherapy Clinic of theQueen's University.

As it is the practicein Canadian physiotherapyprogrammes that each clinical educator will haveonly one student per placement, we had the

opportunity to learn individually and according to our own pace.Under the guidance of our highly experienced clinical educators,

Mr Kris Riseling and Mr Michael Ranger, our skills - especially in assessment and clinical reasoning - were sharpened. In addition, we hadthe chance to put our knowledge into practice,using techniques which benefited our patients.Our clinical educators and the staff of the hospitaland clinic were friendly and made our learningprocess an enjoyable one.

During the weekends, we were able to explore the beautiful country in Ontario andalso visited a few towns. The English-style architecture, the spectacular landscape of thefarms, the unforgettable silhouette of maple treesagainst the sunset and, of course, the wonderfullearning experience will always be in our memories.

Joint PolyU OT/Harvard University Project 2009

This August, four OT students and one recent graduate hada hot and lovely summer in Hunan, serving the children wholive in the orphanages run by International China Concern(ICC). We worked alongside two interns from Harvard ChinaCare who are also students at Harvard University. We spentour first week in Changsha, and stayed with the children in acentre called the Light House. In the Light House, there was a little workshop where the older children made souvenirs asgift to their friends in ICC or for fundraising purposes. Wespent most of the time playing games, dancing and doing artwork with the younger children. They enjoyed going to thepark near the Light House to run around and explore the surroundings. They were all very excited! On our last day, we cooked a meal and ate it in the house of one of theteenagers who used to live in the Light House.

After this, we spent our remaining time at the centre in Hengyang where the children are relatively more disabled. As well as doing assessment and training withthem, using the knowledge we had learnt so far, we all helped with the regular conductive education class run by the centre for children with cerebral palsy. More importantly,we had lots of fun with the lovely children there; we swam,sang, played, drew and had birthday parties with them.

Their big smiles lightened up our days there!We had a good time not just with the children, but

also among ourselves. We explored the area and went sightseeing, playing, eating, singing karaoke and mountainclimbing together during the weekends. We talked about ourlifestyles and values in HK and the US. The whole trip was anawesome and amazing experience.
