Repetitive motion injuries are among the most frequent types of on-the-job injuries. Otherwise called repetitive stress, or continuous trauma or continuous trauma injuries, they come about from tendon overuse that results in inflammation and swelling. Some of the most common of these painful injuries are carpal tunnel and tennis elbow (lateral epicondylitis).

The former is the result of repetitive motion, whether coming about from the wrist, hands or fingers. Through this overuse, arteries, nerves and tendons that surround the bone and ligament structure develop irritation, inflammation and cause significant pain.

Tennis elbow, is a similar affliction of the elbow — it becomes irritated and/or tender resulting from overuse and strain.
