There were two purposes of this study. The first was to research the effects of standard andfixed-split keyboards on wrist posture and movements during word processing. The second was to selectoptimal computer input devices in order to prevent cummulative trauma disorder in the wrist region. Thegroup of subjects consisted of thirteen healthy men and women who all agreed to participate in thisstudy. Kinematic data was measured from both wrist flexion and extension, and wrist radial and ulnardeviation during a 20 minute period of word processing work. The measuring tool was an electrical goniometer,and was produced by Biometrics Cooperation. The results were as follows: 1. The wrist flexionand extension at resting starting position were not significantly different (p>.05), however the angle ofradial and ulnar deviation were significaltly different in standard and split keyboard use during wordprocessing (p<.05). 2. In the initial 10 minutes, the dynamic angle of wrist flexion and extension were notsignificantly different (p>.05), however the dynamic angle of radial and ulnar deviation was significantlydifferent in standard and split keyboard use during word processing (p<.05). These results suggest thatthe split keyboard is more optimal than the standard keyboard, because it prevented excessive ulnar deviationduring word processing.
