Most repetitive stress injuries, including tennis elbow, are caused by tendonitis, an inflammation of the fibrous tissue that connects muscles to bones. Carpal tunnel syndrome, another type of repetitive stress injury, is caused by nerve inflammation in the wrist. Doctors usually treat these conditions with anti-inflammatory drugs, including steroid injections in severe cases. For carpal tunnel syndrome, surgery to "release" pressure on the nerve is sometimes recommended.

Chiropractic, a more conservative approach, is effective for virtually all types of repetitive stress disorders. Adjustments to realign joints and improve range of motion can reduce pressure on tendons and nerves. The movements also improve lymphatic drainage, which reduces inflammation, improves circulation and accelerates healing.
