Before any care is done to the prostheses, the amputee must know exactly how to use it. Special instructors must give instruction to them. These instructing periods will only take a couple hours or a couple weeks. Many times, the amputees become wonderful trainers themselves.
When caring for the prosthesis, it is essential that the inside socket is clean. But, no matter how good you take care of a prosthetic device, it is subjected to reasonable wear and tear. Artificial limbs with joints must be lubricated. Looseness of joints and cracks must be fixed immediately. Prosthetic legs shouldn't be worn without shoes because this will cause excessive wear on both the stump and the artificial part.
For artificial hands and arms, the amputee must remember not to use the prostheses for anything they wouldn't do to a real hand.
