Final answer:
The muscles affected in tennis elbow attach to the lateral epicondyle of the humerus, which are the extensor muscles of the posterior forearm. This condition is often due to the repetitive motion and stress related to certain sports activities like tennis, causing pain and tenderness in the elbow region.
Step-by-step explanation:
The group of muscles affected in a patient with tennis elbow, which attaches to the lateral epicondyle of the humerus, includes the extensor muscles of the posterior forearm. These muscles are primarily responsible for the extension of the wrist and fingers. In the context of tennis, these muscles are frequently engaged during backhand strokes and can lead to overuse injuries.
The lateral epicondyle of the humerus serves as an attachment point for several muscles involved in the extension and manipulation of the forearm and hand. Repetitive movements and excessive strain, especially from sports activities like tennis, can lead to irritation and inflammation of these tendons, resulting in the condition known as tennis elbow, which is characterized by pain and tenderness over the lateral epicondyle region.
Preventing 'tennis elbow' and ensuring proper racquet selection, technique, and training can help to minimize the risk of developing this condition. Additionally, it is important for athletes to balance exercise with proper rest to allow for muscle recovery. If a player is experiencing symptoms of tennis elbow, medical consultation and potential physical therapy may be recommended.
