Movements and Factors Contributing to Tennis Elbow
Demographics and Prevalence
- Tennis elbow primarily affects adults aged 40 and older, involving the dominant arm 75% of the time, highlighting the role of repetitive use in its development 1
Common Causative Movements
- Repetitive wrist extension against resistance is the primary movement pattern that leads to tennis elbow, particularly in racquet sports and occupational activities 1
- Occupations demanding repetitive forearm pronation and supination combined with wrist extension 1
- Computer mouse use and typing that involves sustained wrist extension 2
Biomechanical Factors
- Movements that cause microtrauma at the lateral epicondyle where the forearm extensor muscles originate 1
- Forceful gripping with simultaneous wrist extension creates significant stress on the common extensor origin 2
Warning Signs and Aggravating Movements
- Pain during activities that require stabilizing the wrist in extension while the elbow is straight 2
- Pain exacerbated by shaking hands or opening doors 2
