title: Musculocutaneous nerve entrapment in the upper arm.
abstract: Wasting and weakness of the biceps and brachialis muscles can occur when the musculocutaneous nerve is compressed as it passes through the coracobrachialis muscle; there may also be impairment of sensation on the lateral aspect of the forearm. In our patient, symptoms appeared after strenuous exercise which included more than 500 press-ups each day. Electromyography and telethermic examination confirmed the diagnosis. He was advised to stop his strenuous exercises and within 3 months muscle strength and sensation had returned.
