ABSTRACT
OBJECTIVES: Elderly amputees are a specific clientele because of the interaction of this disease with the ageing process. The objective of this study was to determine the impact of prosthesis rehabilitation on the functional capacity of elderly with lower-limb amputation (LLA) in short and long time. MATERIALS AND METHODS: A quasi-experimental study was developed. The sample consisted of 29 elderly with LLA who finished the prosthesis rehabilitation programme. Gait capacity was evaluated by Functional Ambulation Classification Scale (FAC), ability to perform basic activities of daily living (ADL) was evaluated by Barthel Index (BI) and Pfeffer Questionnaire was used to evaluate the capacity to execute instrumental ADL. Statistical inference was done by t-test, t-student test and chi-squared test. The significance level was fixed at 5% (p < 0.05). RESULTS: In the transtibial group (n = 15) no difference (p = 0.108) was found between BI score before amputation and after 3 months of follow up. The transfemoral group (n = 14) improved significantly (p = 0.045) the FAC before starting and after 3 months of discharge from ambulatory rehabilitation. Both groups increased the time of prosthesis use during the day after 3 months of follow up. However, no group has achieved FAC and Pfeffer Questionnaire pre-amputation performance. CONCLUSION: Although elderly with LLA improved functional capacity after 3 months of a prosthesis rehabilitation programme, they did not achieve their pre-amputation functionality.Implications for rehabilitationLower-limb amputation causes a significant socioeconomic impact and decreases functional capacity, autonomy and quality of life. Elderly people with a lower-limb amputation impose a heavy burden on health resources, requiring extensive rehabilitation and long term care. The specific presentation of elderly persons with lower-limb amputation, with multiple physical, psychological, cognitive, and social comorbidities, imposes unique challenges to ongoing care. The potential bias from the inclusion of younger patients into a study with an elderly population with lower-limb amputation supports the need for independent investigation.In our study we verified that although elderly with transfemoral or transtibial amputation have improved their functional independence after lower-limb prosthesis rehabilitation, they could not achieve their functional capacity before amputation. This improvement especially occurred for the basic activities of daily living, however elderly patients with transfemoral amputations presented greater difficulty in improving functional capacity.These results support that being able to better select elderly by their mobility potential and environmental barriers, is an important goal for future research to aim toward those who will achieve and maintain prosthetic walking or those who could better focus on regaining nonprosthetic mobility.
