Compensatory differences at the trunk and shoulder in transradial body-powered prosthesis users

While body-powered prostheses are the preferred devices following transradial limb loss, the compensatory strategies they elicit are currently not well understood. This study aims to identify at which upper body joints compensation occurs. Based on the findings, body-powered prosthesis users compensate primarily at the trunk and maintain near normal range of motion at the shoulder. This could be explained by the harness system, restricting movement at the shoulder.
