[Use of the Myo Plus system in transradial amputation patients].

Upper limb amputations are uncommon but cause severe disability. It is usually of traumatic origin and in young males less than 40 years-old, and active. The frequency of amputation at transradial level is around 35% of cases, with the myoelectric prosthesis achieving greater functionality. Around 25% of the patients give up using of the prosthesis, due to its complexity of use by means of 2 conventional electrodes, one of the most common causes for giving up. The Myo Plus system with an 8-channel electromyograph helps the patient to control the prosthesis using the phantom limb and achieving the closing, opening, and pronation-supination patterns of the hand in a time less than the conventional one and more easily. It also leads to less rehabilitation time, decreasing costs and unnecessary travel, without increasing the time for the manufacture of the socket.
