What Is a Repetitive Strain Injury?
A Repetitive Strain Injury is a work-related musculoskeletal condition that develops when repeated movements, sustained positions, or ongoing force place stress on the same tissues. Symptoms may affect muscles, tendons, nerves, or joints. Common affected areas include the hands, wrists, elbows, shoulders, neck, and lower back.

Key Takeaways About Repetitive Strain Injury
- Repeated force or motion links the condition to work demands.
- Symptoms may develop gradually during routine tasks.
- A repetitive strain injury is not the same as a sudden accident.
How Repetitive Strain Injury Works

Repetitive Strain Injury develops when a body area receives repeated physical demand without enough recovery. Typing, gripping tools, lifting, reaching, or holding one posture can place ongoing stress on tissues. The affected area may become painful, stiff, weak, or unusually sensitive during or after work.

Assessment focuses on the work task, the body area involved, symptom patterns, and changes in movement. A clinician may ask how symptoms began and whether certain duties increase them. Ergonomic Assessment can help identify workstation or task features that add strain. Range Of Motion testing can show how symptoms affect movement.

From the Arrowhead Clinic Chiropractor Garden City team
When we review a work-related repetitive strain injury, we ask which tasks bring on symptoms and whether posture, force, grip, or repeated motion plays a role. We also consider movement and nearby body regions so the work pattern receives proper context.
