What Causes Tennis Elbow and Who Is at Risk?
Tennis elbow typically develops when the forearm extensor tendons — particularly where they attach at the lateral epicondyle — are subjected to more load than they can comfortably manage over time. This can happen gradually through sustained repetitive effort or more suddenly following a change in activity level or technique.
Common contributing factors include:
- Repetitive gripping, twisting, or wrist extension in occupational tasks
- Racquet and paddle sports — tennis, pickleball, squash — particularly with technique or equipment issues
- Trades and manual work including carpentry, plumbing, electrical, and landscaping
- Prolonged desk work involving mouse-heavy tasks without adequate ergonomic support
- A sudden increase in training volume, a new hobby, or an unfamiliar physical project
In Ottawa, our clinicians regularly work with office professionals, tradespeople, active adults, and athletes at all levels who have developed tennis elbow from the demands of their daily lives. Managing both the symptoms and the underlying loading pattern is essential for durable improvement.
