Tennis Elbow
Tennis elbow, also known as lateral epicondylitis, is a painful condition affecting the outside of the elbow, caused by overuse and inflammation of the tendons that connect forearm muscles to the bone.
Sign and Symptoms
- Overuse and Repetitive Activities: The core cause is repetitive stress on the wrist and arm. While the name suggests a link to tennis (specifically the backhand stroke with poor technique), many other activities are more common culprits.
- Occupational Risks: Jobs that involve repetitive arm movements are a major factor. This includes professions like plumbing, painting, carpentry, butchery, and cooking. Extensive use of a computer mouse and keyboard can also be a cause.
- Sports: Besides tennis, other racquet sports like squash and racquetball can lead to this condition. Throwing sports (e.g., javelin) and activities like weightlifting can also be triggers.
- Hobbies: Activities such as gardening, knitting, or playing musical instruments like the violin can cause the necessary strain.
- Age: It is most common in adults between the ages of 30 and 50.
- Improper Technique or Equipment: Using incorrect form during sports or work activities, or using equipment that is the wrong size or weight (like a tennis racket), can put excessive stress on the elbow tendons.
- Weak Muscles: Having weak forearm or shoulder muscles can contribute to the development of tennis elbow as the tendons are forced to absorb more of the strain.
