Comfort perception assessment in persons with transfemoral amputation

Historically, the design and fitting of prostheses had to rely on a slow process of trial and error, depending on the expertise of the prosthetist. Therefore, a clear definition of the concept of comfort and clear knowledge of its contributing factors are important when designing comfortable prostheses. However, there are currently no standardized methods to adequately measure prosthesis-related comfort. The aim of this study is to identify the factors that underlie the concept of comfort with prosthesis use in transfemoral amputees. Forty-one transfemoral amputees completed a questionnaire to evaluate the perception of comfort and to analyze the influence of six factors. It found a significant model that correctly classifies 84.9% of the cases. It can predict whether the patient feels comfort while using the prosthesis. Although all of the factors were significant, the factors with the greatest influence on the perception of comfort were functionality and pain.
