Do Adaptable Sockets Improve Military Performance?
Abstract
The focus in Year 3 was on data collection. A total of 4 participants completed all three protocols (locked, manual, and auto modes) in the CAREN and FCE-M. Three additional participants have been consented and are partway through socket fabrication. Project logistics were improved at both UW and CFI so that we now have a steady stream of participants proceeding through the study. Collection of bio impedance data was dropped because of instrumentation issues and because sensed distance data from the posterior mid-limb locations provided comparable information. Data analyzed from CAREN testing on two participants to date demonstrated a reduced socket fit error when participants wore the socket in auto mode compared with the locked and manual modes. For FCE-M activities that involved walking, socket fit error was reduced for the auto mode compared with the locked and manual modes. Weight carrying activities caused participant residual limbs to sink deeper into the socket, to which auto mode adjusted to stabilize socket fit.
