LegUp Prosthetics
The Challenge
For below-the-knee amputees, the socket is crucial to the comfort and function of transtibial prosthetics. Due to residual limb volume fluctuation, the use of traditional rigid sockets causes discomfort. In low-resource settings, limited access to fitting services worsens these challenges.
Our Solution
We aim to create a Graphical User Interface (GUI) to help patients in low-resource settings receive access to prosthetic fitting services. Additionally, we aim to design a pressure-sensing network incorporating a 3D-printed socket to collect interface pressure data with participants in order to better fit their socket to their limb.
What We've Accomplished ​
-
Researched ideal dimensions and features for a transtibial prosthesis
-
Developed an adjustable socket system
-
Developed a preliminary Foot and Pylon
-
Researched possible materials to utilize for the fabrication of the prosthesis
-
Built a load-testing setup to evaluate prosthetic components
Current Goals​
-
Build and test the second prototype
-
Test the prototype for functionality and durability
-
Establish a repeatable manufacturing process
-
Develop an orthotic cuff to be used to test a force-sensing network
-
Build, test, and implement the force-sensing network using force-varying resistors
