1. Upper Limb Prosthetic Adaptation/Redesign
Group 6
Cassie Edwards, Meg Stevenson, Amy Thomas, Meagan Williams
Advisor: Dr. Mark Richter

2. Project Objectives
Design or modify an already existing design for an upper limb prosthetic for a boy with upper limb deformities
Create an upper limb prosthesis

3. Existing Device
Drawbacks: Taking prosthesis on and off takes considerable amount of time and effort
Redesign existing prosthesis to make it more functional for an active 8-year-old boy

4. Goals for New Device Short-term Goals Long-term Goals
Dress independently
Go to the bathroom on his own
Long-term Goals
Be able to live independently
i.e. – drive a car, cook for himself, use standard household items, etc.

5. Work Completed
Started working with Aaron Fitzsimmons, a local prosthetist
Learned how to make a cast and discussed ideas for making the prosthesis functional
Made a cast of Matt’s arm and
took measurements of his
extremities

6. Ideas for the Prosthesis
Humeral cuff with Velcro closure
Stump sock interface over humerus
External elbow hinges
Myobock hand with myoelectric interface
Figure 9 suspension
system

7. Current Work
Going to get a Myoboy from Aaron in order to test the electrical activity in Matt’s arm muscles
Obtaining a positive mold of Matt’s arm from Aaron
Use Matt’s arm measurements in order to choose correct sizes for device components

8. Future Work
Start designing a device based on whether or not Matt has enough electrical activity in his muscles
Obtain the parts needed to create the functioning prosthesis
Begin building the device and testing its functionality
