In the source's own words
“Studies have not proved that carpal tunnel is caused by typing on a computer, using a mouse, or repeating movements while working, playing a musical instrument, or playing sports.”
Carpal tunnel syndrome: MedlinePlus Medical Encyclopedia, MedlinePlus, U.S. National Library of Medicine, 2025, Causes.
Open the original- What it measures
- The same passage says these activities may cause tendinitis or bursitis in the hand, which can narrow the carpal tunnel and lead to symptoms, and that vibrating hand tools may lead to the condition. MedlinePlus still advises frequent breaks when typing.
- What it does not show
- Not proven is different from proven safe: typing can still contribute to hand and wrist pain from other conditions, and people who already have symptoms may find typing aggravates them.
