“Multidisciplinary rehabilitation following lower limb amputation plays an important role in restoring function for activities of daily living, work and recreation. Amputee rehabilitation service models and clinical practice guidelines for prosthetic prescription

vary widely throughout the world and have been developed largely from expert consensus.1 and 2 ATR inhibitor In Western Australia, patients achieve independent transfers and wheelchair mobility during inpatient rehabilitation while prosthetic gait retraining is performed as an outpatient service.3 Limited research exists on long-term outcomes in relation to prostheses following discharge from rehabilitation. In particular, there is a lack of quality evidence to inform clinical decisions that may impact on the continued use of prostheses following lower limb amputation.4, 5, 6, 7, 8 and 9 In their literature review, Sansam et al5 called for further investigation of predictive factors to more accurately estimate walking potential because the studies they reviewed reported different predictors; this was probably due to differences in methodology, outcome measures and definitions of prosthetic rehabilitation success. Some studies have quantified prosthetic rehabilitation and success relative to surgery-related outcomes, the duration that the prosthesis

is worn as opposed to functional use, or short-term outcomes while individuals were still participating in rehabilitation; other studies have limited their analyses to cohorts with limited rehabilitation potential.8, 9, 10 and 11 None of these quantify long-term functional prosthetic use following discharge, which is important in understanding the quality of life of these people. In general, for those with atraumatic causes of amputation there is a decline in health status following discharge and 5-year mortality as high as 77%.9, 12, 13 and 14 In some cases, prosthetic gait may impair health and wellbeing through associated morbidity (eg, falls, myocardial infarction) and many individuals stop using their prosthesis within 12 months of discharge.12 and 15 Factors associated with prosthetic outcome have been considered in univariate analyses.
