'Sick worker' malady may be early RSI sign-study

RSI may be responsible for more than wrist pain ...

"Early nerve damage caused by repetitive motion on the job can cause "sick worker" syndrome, a fatigue or depression that can be mistaken for poor work performance, according to a study published in this month's Journal of Neuroimmunology.

The study done on rats found that nerve injuries caused by low-force, highly repetitive movement -- common to typists, pianists and meatpackers, among other professions -- can be blamed on increased production of proteins known as cytokines.

The researchers theorized that as cytokines first appear in the newly injured nerve of workers who perform the same physical movement over and over, signs of "sick worker" syndrome begin.
