ClinConnect Summary

This clinical trial is exploring the use of biofeedback to help individuals with above-knee amputations improve their walking patterns. Biofeedback is a technique that uses wearable sensors to track the movements of patients in real-time. When patients walk, the system gives them feedback through gentle vibrations on their skin, letting them know when they reach the right movements. The goal is to see if this method can help patients learn to walk more effectively and whether those improvements last even after the training is done.

To be eligible for the study, participants must have had a leg amputation between the knee and hip at least a year ago and have experience walking with their current prosthetic leg for at least three months. They should be able to walk for at least 25 minutes with little rest and be classified as community ambulators (K2 and K3 levels). Participants can expect to undergo a single session of biofeedback training, where researchers will measure their walking ability before, during, and after the training. This research may lead to new ways for patients to continue their rehabilitation at home, making it easier for them to access care and improve their mobility.
