Prosthetic training

1. What is the basic motion for opening the terminal device on a transradial prosthetic?
2. What are activities that are important to practice for a unilateral transradial amputee?
3. How is elbow flexion and extension achieved in a transhumeral prosthetic?
4. How is the TD operated with a transhumeral prosthetic?

Answers:
1. Forward flexion of the humerus.
2. Two handed activities such as cutting food or tying shoelaces.
3. Flexion of the elbow is achieved by humeral flexion, and extension of the elbow is achieved by elbow extension back to neutral.
4. When the elbow is locked, use additional humeral flexion to open or close the TD.
