Repetitive Stress Injuries and Workers' Comp

Not all workplace injuries happen in a single dramatic accident. Repetitive stress injuries (RSIs) — also called cumulative trauma disorders — develop gradually from performing the same motions day after day. These injuries are fully compensable under workers' compensation, though they can be harder to prove than acute injuries.

What Are Repetitive Stress Injuries?

Repetitive stress injuries result from repeated microtrauma to muscles, tendons, nerves, and joints. Common work-related RSIs include carpal tunnel syndrome (wrists/hands), tendinitis (shoulder, elbow, wrist), epicondylitis (tennis elbow or golfer's elbow), de Quervain's tenosynovitis (thumb/wrist), trigger finger, bursitis, and thoracic outlet syndrome. Jobs with high RSI risk include assembly line work, meat processing, construction, office work, and healthcare.

When Did the Injury "Occur"?

Unlike acute injuries with a specific date, RSIs develop over time. For workers' comp purposes, the "date of injury" is typically when you first knew or should have known that your condition was work-related and significant enough to require medical attention. This date matters because it starts the statute of limitations clock. Document when your symptoms first appeared and when you connected them to your job duties.

Proving Work Causation

The key challenge in RSI claims is proving your condition was caused or significantly contributed to by your job duties. You need a physician who will document: the specific repetitive tasks you perform, the frequency and duration of those tasks, and a medical opinion that your condition is causally related to those work activities. An occupational medicine physician or orthopedic specialist familiar with workers' comp is ideal.

Employer Defenses in RSI Claims

Employers and insurers commonly argue that RSIs are caused by personal activities (hobbies, sports) rather than work, that the condition is purely degenerative, or that the worker failed to report the injury promptly. Counter these defenses by keeping a detailed work log, limiting outside activities that could be blamed for the injury, and reporting symptoms to your employer and doctor as soon as they develop.

Benefits for Repetitive Stress Injuries

Workers' comp covers the full range of treatment for RSIs — conservative care (bracing, therapy, injections), surgery when necessary, and wage replacement during recovery. If an RSI permanently limits your work capacity, you're entitled to permanent disability benefits. Many RSI cases settle for $15,000–$60,000 depending on severity and occupation.
