UPPER LIMB PROSTHETICS-E. TRANSHUMERAL HARNESS SUSPENSION

SUMMARY

1. In addition to suspending the prosthesis from the shoulders, the transhumeral harness must transmit power to flex the prosthetic forearm, to lock and unlock the elbow unit, and to operate the terminal device.

2. The harness designs most frequently used for transhumeral prostheses are modifications of the basic figure-8 and chest-strap patterns used with transradial prostheses.

3. Body-Powered Control Cable System in transhumeral prostheses uses the dual-control (fair-lead control) cable system for elbow flexion/locking & terminal device operation.
