摘要

Forearm support during keyboard use has been reported to reduce neck and shoulder muscle activity and discomfort. However, the effect of forearm support on wrist posture has not been examined. The aim of this study was to determine the effect of forearm support on posture, muscle activity and discomfort of the forearm/hand and neck/shoulder during keyboard use. In a laboratory study of 13 subjects, forearm support resulted in significantly less ulnar deviation, more time spent in a neutral wrist posture and less reports of discomfort than the traditional "floating" posture. The findings for the neck and shoulder were consistent with previous findings. These positive findings indicate that forearm support may be preferable to the traditional "floating" posture adopted by keyboard users.
