Repetitive Motion / Cumulative Trauma Injury Attorney in Van Nuys, CA
Not every work injury happens in a single moment. California workers’ compensation specifically recognizes “cumulative trauma” or repetitive motion injuries — conditions that develop gradually from repeated physical activity on the job, such as typing, lifting, standing, or repetitive assembly work. Common examples include carpal tunnel syndrome, tendinitis, rotator cuff damage, and degenerative back and joint conditions linked to years of physical work.
Key Points
- The claim deadline for cumulative injuries generally runs from when you knew, or should have known, the condition was work-related — not from a single accident date
- Medical evidence connecting the condition to specific job duties over time is central to these claims
- You can file a cumulative trauma claim even after leaving the job where the repetitive activity occurred, within the applicable time limits
- Multiple employers over the relevant period can sometimes share liability for a single cumulative injury
Considerations
- These claims are often disputed on medical causation grounds — insurers may argue the condition is due to age, a hobby, or another non-work cause
- A detailed work history, including specific tasks, frequency, and duration, strengthens the medical-legal case
- Waiting to report symptoms can allow an insurer to argue delayed reporting undermines the claim’s credibility
California Law Note
California Labor Code § 3208.1 defines cumulative injury as one “ocurring as repetitive mentally or physically traumatic activities extending over a period of time, the combined effect of which causes any disability or need for medical treatment” — a definition specifically written to cover gradual-onset conditions.

How do I know if my injury is covered by workers’ compensation?
Most injuries and illnesses connected to your job duties are covered, whether from a single accident or from repeated activity over time (cumulative trauma). Coverage questions are fact-specific — the most reliable way to find out is a free case evaluation, where the facts of how and when the injury happened can be reviewed directly.
