Nature:

Repetitive strain injury (RSI), also known as occupational overuse syndrome (OOS), is an umbrella term covering all kinds of work-related injuries to the muscles, nerves, and tendons of the upper limbs. RSI is a condition involving pain and swelling in the hands, arms and shoulders suffered by someone working long hours using continuous wrist and hand motions, notably at a computer keyboard and screen.

Incidence:

According to the USA Department of Labour, RSI cost American businesses $20 million in 1992, an eightfold increase from 1982. In 1991, approximately 331,000 people needed wrist splints, anti-inflammatory medication or rest to recover from the ailment. About 100,000 people also underwent surgery to cut the ligament and relieve pressure on the nerve (although this causes loss of hand strength in some people). 2000 lawsuits have been filed in the USA against computer manufacturers by individuals claiming keyboard injury. In 1994, one computer manufacturer put warning labels about the risk of RSI on its keyboards. In the UK and Australia, employers have been sued for not protecting their employees adequately.

Claim:

The existence of known pathological symptoms such as tenosynovitis (inflammatory condition in the tendon sheaths of the wrist) and peritendonitis crepitans (where the former was at the musculo-tendonous junction of the forearm muscles) are well-recognized as caused by repetitive use and overworking. Both conditions have clear clinical signs and a definite pathology.

 

Counter Claim:

Experts are deeply divided about the condition known as RSI. RSI has no medical meaning in that it has no pathology and no clinical symptoms that could be pointed to as confirming a patient suffered from it. The term RSI serves only to confuse and lead to speculation, not only as to what the patient was suffering, but also as to its causation. Ergonomists are well-meaning but too ready to define the causation.
