This study looks at whether microprocessor-controlled prosthetic knees (MPKs) — knees with a built-in computer — can reduce fall-related health problems in adults who use an above-knee artificial leg. About 100 participants who already use a standard non-computerized knee will be…

This study tests a wearable device that uses gentle vibrations to help reduce phantom limb pain in people who have lost a leg. Twenty participants will use the device daily for 3 weeks and report their pain, walking ability, and quality of life. The device is already certified as…

This study tests whether a non-invasive treatment called TENS (gentle electrical pulses through the skin) can reduce phantom limb pain and improve balance and walking in people who have lost a leg. Fifteen adults with above- or below-knee amputations will attend 20 sessions over …

This study aims to understand what happens inside the tissue after a leg amputation above the knee. Researchers will use a tiny probe (microdialysis) to measure chemicals related to blood flow, inflammation, and antibiotics in the stump. The study includes 20 adults with and with…
