Development of Sub-Ischial Prosthetic Sockets with Vacuum-Assisted Suspension for Highly Active Persons with Transfemoral Amputations
Abstract
The purpose of this project is to develop a highly flexible sub-ischial prosthetic socket with assisted-vacuum suspension for highly active persons with transfemoral amputation. The Specific Aims are to: A1. Develop a highly flexible socket with sub-ischial trim lines; A2. Develop durable liners and sealing sleeves; A3. Develop/identify an appropriate vacuum pump; A4. Evaluate system performance with military amputees; and A5. Develop education materials. During Year 3, for Aims 1 and 2, we have developed a process for automated fabrication of the socket. For Aim 3, we have created a working prototype of the hybrid mechanical-electrical pump design. For Aim 4 we have enrolled 4 of the 6 subjects and testing is underway. For Aim 5, we have continued development of education materials to facilitate dissemination of this technique.
