[Clinico-electromyographic evaluation of the state of motor units of the hand muscles replanted after traumatic amputation].

Needle electromyography was used to study motor units of the muscles leading away the thumb and little finger, replanted after traumatic amputation of the large segment of the upper limb in 34 patients. A direct relationship was discovered between the time of the appearance of action potentials of motor units (PMU), recovery of the movements, and trauma level. The appearance of clear PMU associated with movement recovery was recorded not earlier than 6-7 months after trauma. Analysis of PMU is a reliable criterion for the recovery of the own movements of the muscles and function of the neuromotor apparatus in patients with the replanted upper limb segment.
