Impact of Powered Knee-Ankle Prosthesis Leg on Everyday Community Mobility and Social Interaction

Running, not enrolling · Not applicable

Conditions studied: Transfemoral Amputees

In brief

The overall goal of this research is to determine the efficacy of new powered prosthetic devices for individuals with transfemoral amputations. The anticipation is that this will be a high-impact technological intervention with the potential to restore significant functionality to individuals with lower limb amputation and transform the field of lower limb prosthetics. The objective of the proposed clinical trial is to fully evaluate the biomechanical and energetic effects of using PKA prosthesis and quantify functional performance and quality of life changes.
