Preliminary Evaluation of a Diagnostic Tool for Prosthetics
Abstract
The purpose of this research was to integrate a novel limb fluid volume measurement instrument into clinical prosthetics, andthen to evaluate its effectiveness to enhance prosthetic design and fitting. The instrument is a portable, custom, bioimpedance analysis system specifically developed for trans-tibial residual limb fluid volume measurement. An observational cohort study and a randomized control trial were conducted. Participants with transtibial amputation were tested before they underwent prosthesis modification/replacement by their prosthetist and after their prosthetic fitting was completed. Results demonstrated that participants who underwent socket replacement had higher self-reported outcomes than those who had socket modification. The residual limb fluid volume loss measured by the instrument during a scripted testing protocol before treatment compared with after treatment was related to participant self-reported outcome, and thus may be a useful metric to gauge the need for socket replacement.
