Summary

This study tested a new digital system for creating prosthetic sockets while the person is standing (weight-bearing). The goal was to see if this method leads to a better fit, more comfort, and improved skin health compared to traditional non-weight-bearing methods. Ten adults with below-knee amputations who walk well participated. The results may help amputees have healthier residual limbs and better rehabilitation outcomes.
