摘要: Long weekly hours of keyboard use may lead to or aggravate carpal tunnel syndrome. The effects typing on fluid pressure in the tunnel, a possible mediator syndrome, are unknown. Twenty healthy subjects participated laboratory study investigate at different wrist postures right hand. Changes flexion/extension angle (p = 0.01) and radial/ulnar deviation 0.03) independently altered pressure; deviations extension radial were associated with an increase pressure. activity elevated 0.001) relative static hand held same posture. This information can guide design keyboards workstations order minimize while typing. findings also be useful clinicians ergonomists management patients syndrome who keyboard.
