In medicine, a prosthesis, is an artificial device that replaces a missing body part, which may be lost through trauma, disease, or congenital conditions. Prosthetic amputee rehabilitation is primarily coordinated by a prosthetist and an inter-disciplinary team of health care professionals including physiotherapists.

A person’s prosthesis should be designed and assembled according to the patient’s appearance and functional needs. For instance, a patient may need a transradial prosthesis, but need to choose between an aesthetic functional device, a myoelectric device, a body-powered device, or an activity specific device. Depending on the patient’s economical capabilities, they may have the option to choose more than one device.
