Factors that influence the level of activities in persons with lower extremity amputation.

This study explored the problems of prosthesis use in four dimensions of activity in 122 males and 9 females, aged 24 to 90 years, with lower extremity amputations. Comparisons were made between persons with above-the-knee amputation and those with below-the-knee amputation. A four-dimensional prosthetic problem inventory scale developed by the investigators was used. Results of this study provide a framework for identifying and addressing problematic areas in the use of prostheses.
