LegUp Prosthetics
The Challenge
For below-the-knee amputees, the socket is crucial to the comfort and function of transtibial prosthetics. Due residual limb volume fluctuation, the use of traditional rigid sockets causes discomfort. For children, this issue is amplified by rapid growth, requiring frequent adjustments. In low-resource settings, limited access to fitting services worsens these challenges.
Our Solution
We aim to create a modular, adjustable transtibial prosthetic for children, with interchangeable parts that accommodate growth and ensure comfort.

Our Team Structure
Our team is divided into three subteams for focused development:​
​​
-
Design: Responsible for developing and iterating on the prosthetic socket’s mechanical structure. This includes CAD modeling, socket geometry, strap systems, adapter integration, and overall fit. Learn more →
-
Testing: Focuses on validating the strength, comfort, and functionality of our prototypes. This includes adhesive strength testing, load-bearing evaluations, and pressure distribution studies using finite element analysis. Learn more →
-
Materials: Researches and sources appropriate foams, adhesives, fabrics, and 3D-printing materials. They evaluate each component for durability, comfort, biocompatibility, and cost-effectiveness. They also lead development of the inner socket interface, including foam layering and mesh integration. Learn more →
