This trial tests a new type of prosthetic liner that lets moisture escape, aiming to reduce the sweating and heat that often build up inside a traditional airtight liner. Adults with above-knee amputations who already use a direct socket will wear the breathable liner and socket …

This trial tests the Nike Sport Sole, an accessory that attaches to the Cheetah Xceed running prosthetic foot. The sole comes in two versions: a traction sole for general running and a spike pad for track use. Researchers will have three people with below-knee amputations use the…

This study tested whether a new prosthetic foot called the Pro-Flex Pivot helps people with below-knee amputations move better than a standard energy-storing foot. Thirty adults who already use a standard foot wore each type for four weeks and reported their mobility and comfort.…

This study tested a new microprocessor-controlled prosthetic knee called NAVii in 14 people with leg amputations. Participants tried the new knee and then their usual knee, and researchers compared how satisfied they were walking downstairs and how far they could walk in six minu…

This study tested a motorized, computer-controlled knee (Mobili Knee) in 6 people who had a leg amputation above the knee and used a prosthetic. Participants performed walking and balance tests with their usual knee and with the powered knee. The goal was to see if the powered kn…

This study tested a new powered prosthetic knee called Power Knee in 17 people with above-knee amputations. The goal was to see if it reduces effort during walking compared to their usual microprocessor knee. Participants walked for 6 minutes and rated their exertion. The study a…

This study tested a new microprocessor-controlled prosthetic knee (Navii Knee) in 11 people with above-knee amputations. Participants used the new knee for 4 weeks at home, and researchers measured satisfaction with stair and ramp descent, walking, balance, and overall quality of…

This study evaluates how long a new thermoplastic elastomer (TPE) material lasts when used in prosthetic liners and sleeves. People with below-knee amputations who already use such liners will wear the investigational device as their primary prosthesis for up to 6 months. Researc…

This study tested a new prosthetic foot for children with leg amputations or birth defects. Thirteen kids walked with the device and gave feedback on stiffness and performance. The goal was to gather ideas to improve future foot designs.
