Abstract The supinator muscle is susceptible to the development of myofascial pain syndrome. This pain is most often the result of repetitive microtrauma to the muscle caused by such activities…

Abstract The anconeus muscle is susceptible to the development of myofascial pain syndrome. Stretch or impact injuries to the anconeus muscle sustained while playing tennis or with overuse such as…

Abstract Ulnar nerve entrapment at the elbow is one of the most common entrapment neuropathies encountered in clinical practice. Causes include compression of the ulnar nerve by an aponeurotic band…

Abstract Tennis elbow (also known as lateral epicondylitis) is caused by repetitive microtrauma to the extensor tendons of the forearm. The pathophysiology of tennis elbow initially involves microtearing at the…

Abstract Rotator cuff tears are a common cause of shoulder pain and dysfunction. A rotator cuff tear frequently occurs after seemingly minor trauma to the musculotendinous unit of the shoulder….

Abstract The teres major muscle is susceptible to the development of myofascial pain syndrome. Stretch or impact injuries to the teres major muscle sustained while playing sports or in motor…

Abstract The biceps muscle and tendons are intimately involved in shoulder and upper extremity function and are susceptible to trauma and to wear and tear. Biceps tendon tear is usually…

Abstract The deltoid muscle is susceptible to the development of myofascial pain syndrome. Flexion-extension and lateral motion stretch injuries or impact injuries to the deltoid muscle during football or repeated…

Abstract Scapulocostal syndrome is an overuse syndrome caused by repeated improper use of the muscles of scapular stabilization—the levator scapulae, pectoralis minor, serratus anterior, rhomboids, and, to a lesser extent,…

Abstract The supraspinatus muscle is susceptible to the development of myofascial pain syndrome. Flexion-extension and lateral motion stretch injuries to the neck, shoulder, and upper back or repeated microtrauma secondary…
