While widely known for its sophisticated performance, a myoelectric arm also places certain demands on upper extremity amputees. Before a fitting is even considered, an amputee must demonstrate both the ability and the inclination to use this advanced technology to its full capabilities.
Myoelectric arms meet different needs than conventional upper extremity devices.
As with any prosthesis, a myoelectric arm offers advantages while imposing certain demands. Particularly because a myoelectric device is more costly, amputees must also show the rehabilitation team and reimbursement source that the arm's benefits outweigh other considerations such as the greater care this unit requires. Electric hands provide stronger grasp and electric elbows allow easier control of raising and lowering movements. Plus, they are part of a natural-appearing, cosmetic arm. Further benefits include not needing control cables, which are uncomfortable, and which can, over time, cause nerve damage to the sound arm.
