Repetitive strain injuries — encompassing carpal tunnel syndrome, tendinitis, trigger finger, and a range of other musculoskeletal disorders caused by repeated motions — are among the most prevalent and costly occupational health conditions in the United States. As computer-intensive work expands and remote work removes ergonomic safeguards common in corporate offices, RSI rates in knowledge workers have climbed. The statistics below come from BLS, OSHA, NIOSH, NIH, and peer-reviewed occupational medicine research.

Frequently Asked Questions

How many people suffer from RSI in the U.S.?

Over 1.8 million U.S. workers are affected by RSI and repetitive motion disorders annually, according to BLS and NIOSH data. Carpal tunnel syndrome alone accounts for approximately 900,000 new cases per year, with 4–10 million Americans living with the condition.

What jobs have the highest RSI risk?

Meat packing and food processing workers (19.3% RSI rate), manufacturing/assembly workers (15.1%), and healthcare support workers (12.4%) have the highest rates. Among office workers, those using computers more than 4 hours per day have 3x higher carpal tunnel risk.

How much does RSI cost U.S. employers?

RSI and repetitive motion disorders cost U.S. employers an estimated $20 billion annually in workers' compensation, medical costs, and lost productivity. A single carpal tunnel case requiring surgery can cost an employer $30,000+ in total burden.

Can ergonomic keyboards and mice prevent RSI?

Yes. Research shows ergonomic keyboards reduce wrist strain by 30–50%, and vertical ergonomic mice reduce forearm pronation stress by up to 75%. Combined with microbreak schedules, comprehensive ergonomic interventions reduce RSI symptoms by 56% in office workers.

What is the most common type of RSI?

Carpal tunnel syndrome (CTS) is the most common diagnosed RSI, affecting approximately 4–10 million Americans. Tendinitis, trigger finger, and lateral/medial epicondylitis (tennis/golfer's elbow) are also common RSI conditions in computer-intensive and manual labor settings.
