ClinConnect Summary

This clinical trial is studying a new type of gait training for people who have had an above-knee amputation or knee disarticulation on one leg. Because losing the knee joint can make walking uneven, unstable, and tiring, this study is testing a special system that uses real-time motion capture and visual feedback to help improve walking patterns. The system shows a live image of the person’s walking on a screen, allowing them to see and adjust their movements instantly. The goal is to help participants walk more smoothly and confidently by giving clear, easy-to-understand feedback about their joint movements and walking symmetry.

People who might be eligible to join are adults between 18 and 65 years old who have one above-knee amputation or knee disarticulation, use a prosthetic leg for at least 3 hours a day, and have been using it for more than six months. Participants should be able to walk on their own for at least 5 meters without help, have no pain from their prosthetic fit, and pass a simple cognitive test. The study is not yet recruiting participants, but if you qualify, you can expect to participate in gait training sessions using this motion capture system that aims to help improve both your walking mechanics and how you feel about walking. This innovative approach may offer a more precise and user-friendly way to support better walking after amputation.
