Development of Adaptive Vacuum Suspension to Improve Prosthetic Fit and Residual Limb Health
Abstract
The overall objective of proposed study is to develop an adaptive socket system that detects in-socket residual limb motion and dynamically adjusts internal socket negative pressure to optimize fit and performance. Specific Aim 1: Test relationship of pressure variance waveforms with residual limb movement in-socket.Hypothesis 1: Pressure data will detect distal displacement and lateral shift of the residual limb inside the socket. SpecificAim 2: Characterize the effects of residual limb movement in-socket on residual limb health. Hypothesis 2: Increased socket motion decreases residual limb perfusion and disrupts skin barrier function. Specific Aim 3: Compare the long-term effects of adaptive Elevated Vacuum Suspension (EVS) to pin-locking and suction suspension systems. Hypothesis 3.1: Adaptive EVSimproves amputee performance and residual limb health as compared to pin-locking/lanyard, suction, and static EVS.Hypothesis 3.2: Adaptive EVS improves functional performance, pistoning control, and user comfort as compared to pinlocking/lanyard, and static EVS.
