New study aims to take the guesswork out of prosthetic fit for amputees
NCT ID NCT07521891
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how well a prosthetic leg socket fits people who have a below-knee amputation. Researchers will measure the movement between the socket and the leg while participants walk and do other tasks. Twenty volunteers will test three different suspension systems during one lab visit. The goal is to help doctors and prosthetists choose the best fit for each person.
