TRANSFEMORAL AMPUTATION

This study tests whether a powered, computer-controlled prosthetic knee helps people with above-knee amputations use less energy while walking on flat and sloped surfaces compared to their usual prosthesis. Researchers will measure oxygen use, balance confidence, and perceived ef…

This study tests whether a powered prosthetic knee (the Ossur Power Knee) helps people with above-knee amputations walk better than a standard passive knee. About 20 adults aged 45-75 who have used a prosthetic leg for at least a year will take part. Researchers will measure walk…

This study compares a new adjustable prosthetic socket to a standard one in 40 veterans with below- or above-knee amputations. The goal is to see if the adjustable socket improves walking, comfort, and satisfaction. Participants will try both sockets so researchers can find the b…

This study tests whether an AI system (called RISE) can help doctors and prosthetists personalize a robotic prosthetic leg more quickly and effectively than current manual methods. About 24 adults with above-knee amputations will walk on different terrains while their prosthetic …

This study tests a smart prosthetic leg that uses muscle signals from the user's thigh to control the knee and ankle. Ten adults with above-knee amputations will try the device on flat ground, stairs, and other real-world tasks. Researchers will measure how well the leg moves, ho…
