Document Summary
Lateral epicondyle attachment site for wrist flexors. Supinator muscle (doesn"t attach directly to epicondyle but still functions with flexors) Tennis elbow: epicondylitis or tendinopathy, we"re dealing with a tendinopathy, chronic failure of the tendons attaching to lateral epicondyle, extensor carpi radialis brevis (ecrb, extensor digitorum communis (edc, radial head closest structural relationship to ecrb & edc. Prominent, tendons stretch around it and are subject to compression within their joints. (most subject to tendinopathy: acute to chronic progression. Chronic degenerative process: elite tennis players are more likely to have shoulder problems than elbow. Back hand swing needs scapula retractor muscles: teres major, deltoid. If these muscles are weak, then the forearm will have to contract more, making it more prone to tennis elbow. Factors to consider: exercise prescription, grip strength; might weaken due to tendinopathy, therefore work on this, eccentric wrist extensors; maximize this strength as it will help prevent and treat tennis elbow.
