The biggest rehabilitation problem after myocutaneous nerve injury is biceps paralysis, which has a greater impact on daily life and work, so the treatment should focus on restoring the function of the biceps. This muscle is superficial, the patient can see its contraction activity, and the method of muscle strength exercise is relatively simple and easy for the patient to master. In the early stages, when the muscle strength is below grade 3, weight-reduction elbow training can be performed using a skateboard or on a smooth table. When the muscle strength is above level 3, resistance exercises, such as dumbbells, sandbags, spring tensioners, and even household items such as buckets can be used. To prevent elbow extension contracture, a flexion sling can be applied. Apply physical therapy as appropriate. If the biceps recovery is poor and slow, the radial nerve innervated brachioradialis muscle can be trained to compensate for the flexion of the elbow.
