Upper Extremity Prosthetics/ Socket Prostheses Control: Targeted Reinnervation- Surgical Outcome of 30 patients (trans-humeral or shoulder disarticulation amputees) Dr Laura Miller, USA Hyper- innervation (ie transfer large nerve fibres onto smaller muscles) Improved Activation ( to allow use of myo-electric prostheses) Adapted from L Miller et al, 13 th ISPO World Congress, 2010

Effectiveness of a Evidence Based Amputee Rehabilitation Programme Bob Gailey, PT, USA • • RCT 3 exercise sessions per week v’s waitlist control 8 week programme 16 subjects (of 345 amputees asked to participate) Age (av. ): 63 years Time since amputation (av. ): 8 years 75% PVD or DM

5 Components of Exercise Programme 1. 2. 3. 4. 5. Cardiopulmonary endurance Core strengthening & power Balance & co-ordination Weight bearing and stance control Prosthetic gait training Adapted from R Gailey, 13 th ISPO World Congress, 2010

A single blind cross-over trial of hip abductor strength training to improve gait & balance in patients with unilateral, trans-femoral amputation. T Pauley, PT, Canada Method: • Cross-over design • Min 6 months post fitting • Hip abductor strengthening machine • ACSM guidelines etc • Control used arm ergometer • 14 subjects • 2 minute walk test, timed up & go, ? balance measure

Reliability of 5 high-level activity measures established for military service members with traumatic lower limb loss. Alison Linberg, PT, USA Inter-rater & test-retest reliability of 83 amputee & 97 uninjured military personnel 1. 2. 3. 4. 5. Single leg stance Seated medicine ball put Modified Edgren side-step test T-test Illinois agility test

Speed & Agility Measures • Modified Edgren Side Step Test: measures side stepping distance over 4 metre course in 10 seconds • T-Test: measures time negotiating a 10 m forward, 10 m side to side, 10 m backwards. • Illinois Agility Test: From prone, measures time rapidly moving forward, diagonally and weaving along a 10 m x 5 m course. Adapted from I Gaunaurd, 13 th ISPO World Congress, 2010

Background • • Ceiling effect of usual measures Technological improvements Return to duty Five chosen tests commonly used in sports medicine Adapted from K Linberg et al, 13 th ISPO World Congress, 2010

Results • Excellent inter-rater reliability in both groups ( ie ICC > 0. 9) • Moderate/ good test-retest scores in normals • Good/ excellent test-retest scores in amputees • (Nb: Still need validity studies eg correlation with job tasks etc) Adapted from A Linberg et al, 13 th ISPO World Congress, 2010

Speed & agility testing of military service members with traumatic lower limb loss I Gaunaurd et al • Edgren Side Step Test, T-Test & Illinois Agility Test. • Comparison between amputees and non-amputee service members ( control). • Non-amputees performed better than TT and TF amputees. • TT amputees performed better than TF amputees. • 51% of unilateral TT amputees performed within the range of scores for the 3 tests for the non-amputees.

Improving outcomes for bilateral trans-femoral amputees Kevin Carroll, P&O, USA Phases 1. Building confidence 2. Walking on short legs ( stubbies) 3. Graduated increase in height 4. Walking on full length prosthetic legs Adapted from K Carroll, 13 th ISPO World Congress, 2010

Improving outcomes for bilateral TF cont. Increasing numbers Patients have higher expectations Teach patients how to fall and get up Practise on grass ( patients will fall!) Need micro-processor knees, especially on stairs and ramps ( less falls than standard knees & can walk step over step) • Peer support • • • Adapted from K Carroll, 13 th ISPO World Congress, 2010

Virtual Reality (VR) Based Training and Assessment in Persons with Lower Extremity Amputation. B Darter et al Method: • Amputee on treadmill • VR goggles/ markers etc • 12 sessions over 3 weeks • 3 times 10 mins VR walking/ session • Standing balance & gait training using VR • Provides real time feedback, unexpected obstacles/ stumble recovery and external focus of attention

Virtual Reality cont. Results: • 15 % improvement in metabolic cost • Marked improvement in trunk motion symmetry • Controlled environment gives patients licence to push themselves • Improved reaction times • Subtle differences in recovery strategy could be noted. • Study ongoing.

Osseointegration • Increased prosthetic use with OI. 93% use OI prosthesis. 40% use prosthesis >15 hours per day. Ongoing study. (K Hagberg) • 40% ( of 45) had some form of infection, mostly minor. Infection not an obstacle to OI. (J Tilander) • OPRA programme. Most complications can be handled without surgery. 4 of 42 implants removed because of loosening and/or deep infection. Study ongoing.
