AbstractThis case report presents a patient who developed right shoulder pain following strenuous upper-extremity exercise. Approximately 6 weeks later his pain resolved, he noticed persistent right upper-extremity weakness. He was referred to physical therapy for evaluation and treatment. Physical therapy evaluation revealed isolated serratus anterior muscle paralysis. A long thoracic neuropathy was subsequently confirmed by electromyographic testing. The etiology, pathophysiology, and pathokinesiology of serratus anterior muscle paralysis are reviewed. A case is presented, illustrating how the clinical decision making is based on the pathokinesiology and pathophysiology. The patient was followed over the course of 17 months and has recovered full right shoulder active range of motion. His serratus anterior muscle strength has increased to Good minus, and he reports significantly improved functional use of the upper extremity.
