Motor recovery after bilateral brachial plexus injury using motor irradiation: a case report

Abstract

Background/Aims Brachial plexus injuries impair functionality, interfere with the performance of activities and affect participation in social events, thus decreasing an individual's quality of life. In cases where there is a total loss of muscular strength, complete rehabilitation is challenging. Motor irradiation is a basic proprioceptive neuromuscular facilitation procedure that is used to activate weak muscles. It is a promising procedure for rehabilitation following brachial plexus injuries, mainly in those with total loss of muscle strength. Methods The patient in this case study had suffered bilateral brachial plexus injuries as a result of mechanical restraint during a psychiatric episode. He presented with decreased muscle strength in the proximal segments of the upper limbs, no movement of the wrists and fingers, tactile hypoesthesia and no pain sensation. Motor irradiation was the main intervention used to improve motor function. Findings At the end of treatment, complete and partial recovery of muscle strength was observed in the proximal and distal segments, respectively. Conclusions The efficacy of motor irradiation in improving muscle strength following brachial plexus injuries should be investigated in future clinical trials.
