Harness System
A network of straps and cables worn around the torso or shoulder girdle to suspend and/or control an upper-limb prosthesis.
Full Definition
A harness system is a body-powered suspension and control interface consisting of straps, figure-of-eight or figure-of-nine configurations, and Bowden cables. It anchors an upper-limb prosthesis to the body and transmits shoulder or scapular motion to operate terminal devices or elbow units. Editors frequently encounter the term in clinical notes, prescription forms, and insurance appeals. It should not be confused with the suspension system of a lower-limb prosthesis, which operates on different mechanical principles. Capitalisation is not required unless part of a proprietary product name.
Usage
Usage note: Specify the harness configuration (figure-of-eight, figure-of-nine, chest strap) when editing clinical or billing documents, as each configuration has distinct L-Code implications.
