Transfemoral amputation

This study compares a new adjustable prosthetic socket to a standard rigid socket in 40 veterans with leg amputations. Participants will walk on a treadmill at different speeds while researchers measure how evenly they walk and how comfortable the socket feels. The goal is to fin…

This study tests whether a powered, computer-controlled prosthetic knee helps people with above-knee amputations walk more efficiently than their usual prosthesis. Researchers will measure oxygen use during walking on flat and sloped surfaces, along with balance confidence and ef…

This study compares a powered prosthetic knee (Ossur Power Knee) to a standard microprocessor knee in 20 people with above-knee amputations. Participants will use each knee for a month, then researchers measure walking speed, energy use, and sit-to-stand movements. The goal is to…

Researchers are studying how muscle strength, balance, and walking ability differ in people with an above-knee amputation. The study measures strength at the hip, knee, and ankle of the intact leg, tests balance on a force platform, and records how far participants walk in six mi…

This study tests a new AI system that helps doctors and prosthetists quickly tune robotic prosthetic legs for people with above-knee amputations. 24 participants will compare AI-guided tuning against manual tuning to see which is faster and leads to better walking. The goal is to…

This study tests a bionic leg that uses muscle signals from the user's residual limb to control the knee and ankle. Ten people with above-knee amputations will compare walking with this smart prosthesis versus their regular one. The goal is to see if the bionic leg feels more lik…
