Do Microprocessor Knees Improve Outcomes in Early Prosthetic Rehabilitation Compared to Nonmicroprocessor Knees

Microprocessor knees have great potential to improve rehabilitation following transfemoral amputation. However, there is little evidence to direct prosthetic care, including prosthetic knee prescription, in the early stages of rehabilitation. The goal of this project is to evaluate the effect of microprocessor and non-microprocessor knees on overall function, health, and quality of life following amputation. A pilot randomized controlled trial is underway to compare falls, step activity, balance confidence, mobility, health-related quality of life, and community integration of people with recent transfemoral amputation in two prosthetic knee conditions a microprocessor knee with control of stance phase and a non-microprocessor knee that is appropriate for people in early rehabilitation. Through this pilot study, we will better understand prescription criteria for use of MPKs in early rehabilitation, and identify characteristics of patients who are most likely to benefit from different knee technologies.
