Repetitive strain injury (RSI) refers to a group of conditions characterized by gradual onset and worsening symptoms affecting the musculoskeletal and nervous systems following repetitive activities. RSIs are also known as repetitive motion injuries and cumulative trauma disorders. Repetitive motion, prolonged fixed or awkward positioning, forceful exertions, vibrations, and mechanical compression are RSI risk factors.
- Symptoms are present in body parts used most for the activity.
- RSIs are linked to serious conditions affecting the neck, back, shoulders, arms, and hands.
