What is a common adjustment made to accommodate a TH amputee’s shoulder strength limitations?

Using lightweight prosthetic materials is a common adjustment made to accommodate a transhumeral (TH) amputee's shoulder strength limitations. Transhumeral amputees often experience reduced shoulder strength and stability due to the loss of the upper arm. As a result, using lightweight materials in prosthetic design helps to minimize the overall weight of the device. This reduction in weight alleviates the strain on the shoulder muscles, making it easier for the user to lift and maneuver the prosthesis effectively.

Moreover, by utilizing materials such as carbon fiber or other advanced composites, prosthetists can create devices that are both strong and lightweight. This enhances the comfort and usability of the prosthetic limb, allowing for a more functional experience for the amputee.

On the other hand, adjustments involving a heavier elbow lock may increase the load on the shoulder rather than relieve it, and incorporating pulley systems might not always be practical or effective for all users. Changing to a lighter terminal device can also help, but if the overall weight of the prosthetic is not addressed by using lightweight materials, it may not be sufficient to fully accommodate the shoulder strength limitations faced by transhumeral amputees.
