“There is insufficient epidemiological evidence that computer work causes CTS.”
Carpal tunnel syndrome and the use of computer mouse and keyboard: A systematic review, Jane Frolund Thomsen et al., BMC Musculoskeletal Disorders, 2008, Abstract, Conclusion.
Open the original (DOI 10.1186/1471-2474-9-134)- What it measures
- All eight studies had limitations such as imprecise measurement of exposure and outcome, low statistical power or possible bias. Carpal tunnel pressure during typical computer use was below harmful levels, although one study measured potentially harmful pressure during actual mouse use.
- What it does not show
- Published in 2008 and based on few, imperfect studies. Insufficient evidence of cause is not evidence of safety, and the review does not cover other hand, wrist or forearm pain linked to computer use.
