Study Summary
Prospective two group cross over investigation, comparing the investigational device (Power Knee, a powered microprocessor controlled prosthetic knee) and subjects prescribed microprocessor prosthetic knee (MPK). The primary objective was to evaluate the efficacy of the investigational device in reducing exertion during walking compared to passive MPKs. Additionally to evaluate the efficacy of the investigational device in the short and long term compared to passive MPKs and previous versions of the Power Knee, during daily living activities i.e. walking on level ground, in stairs and inclines, rising from and sitting down to a chair as well as performance of gait functions and ease of set up for average to highly active transfemoral/knee disarticulation amputees and Certified Prosthetists/Orthotists (CPOs).
Primary Outcome
Mean difference in perceived exertion on the Borg rating scale of perceived exertion before and after 6 minute walk test (6MWT) (see outcome 2) with investigational device (Power Knee) compared to comparator (prescribed device). Subjects are asked how exerted they feel on a scale of 0-10 (0 indicating no exertion and 10 indicating the most exertion) at rest before they carry out the 6MWT, and after carrying out the 6MWT, the difference is recorded. The Borg Category Rating 10 scale (CR10) is a
