A Release/Relock Socket to Enhance Volume Management and Facilitate Patient Self-Care
Abstract
A motor-driven release-relock system was developed that allowed people with transtibial amputation to quickly and easily partially doff or fully doff their prosthesis. The design implemented a control system to allow users to change prosthesis states (donned, partially doffed, fully doffed) with the push of a button. The unit also recorded prosthesis use - walks, weight shifts, stationary and doffs. Testing in the lab using a scripted protocol demonstrated a significant decrease in residual limb fluid volume loss when 4-min or 10-min partial doffs were executed compared with no socket release. Take home testing showed differences in prosthesis use when release-relock was available compared with a locked control, though the activity changes varied among the participants. Prosthetist participants were excited about the collected data because it provided meaningful clinical insight about how their patients used their prosthesis, information they considered useful for insurance justification, to help set activity goals and to monitor progress.
