Lightweight Powered Knee-Ankle Prosthesis for Community Ambulation
W81XWH2110037 – T. Lenzi (PI)
Department of Defense, Congressionally Directed Medical Research Program (CDMRP-DMDRP-JC8- RESTORE)
04/01/2021-03/31/2025 – $1,498,000
Description: The objective of this project is to provide the first demonstration of a powered knee-ankle prosthesis at home and in the community. To this end, we will develop a new version of our powered knee-ankle prosthesis that satisfies ISO standards for structural testing, select the optimal prosthesis configuration through preclinical, laboratory testing with individuals with above-knee amputation and conduct a pilot clinical trial with three individuals with an above-knee amputation using our lightweight powered leg at home.
