Summary
Adjustable transtibial prostheses significantly improved patient comfort and eliminated skin breakdown, a common issue with conventional sockets. This innovation offers a solution for individuals experiencing residual limb volume fluctuations.
Area of Science:
- Biomedical Engineering
- Orthotics and Prosthetics
Background:
- Conventional hard sockets for transtibial prostheses cause skin breakdown in nearly half of users.
- Residual limb volume changes frequently lead to poor socket fit, skin irritation, and breakdown, especially problematic for individuals with diabetes.
