Speed's test is a special test meant to identify tendonitis in the bicep. The bicep muscle has two tendons that connect it to the shoulder bone. It also has one to connect it with the radius bone in the forearm. Overuse from activities like golf, tennis, and weight-lifting can cause tiny tears in these tendons. This often leads to tendonitis. To perform the Speed's Test, the examiner places the patient's arm in shoulder flexion, external rotation, full elbow extension, and forearm supination; manual resistance is then applied by the examiner in a downward direction. A positive Speed's test result is usually thought to suggest inflammation or lesions related to the biceps/labral complex.
