Tracking training evolution: patient with upper limb amputation above the elbow.

This article describes a patient training evolution to achieve myoelectric control in the remnant limb. The methodology is divided in two main stages: (i) the training procedure, where the patient is submitted to a protocol for educating the muscles of the remnant limb, and (ii) myoelectric signal acquisition and analysis, in order to measure the patient evolution to reach different contraction levels along the training sessions. After three training stages, the results suggest that the patient gradually achieved strength control over the muscles of the remnant limb.
