[Purpose] This study showed the effects of different computer typing speeds on
acceleration and peak contact pressure of the fingertips during computer typing.
[Subjects] Twenty-one male computer workers voluntarily consented to participate in this
study. They consisted of 7 workers who could type 200–300 characteristics/minute, 7
workers who could type 300–400 characteristics/minute, and 7 workers who could type
400–500 chracteristics/minute. [Methods] This study was used to measure the acceleration
and peak contact pressure of the fingertips for different typing speed groups using an
accelerometer and CONFORMat system. [Results] The fingertip contact pressure was increased
in the high typing speed group compared with the low and medium typing speed groups. The
fingertip acceleration was increased in the high typing speed group compared with the low
and medium typing speed groups. [Conclusion] The results of the present study indicate
that a fast typing speed cause continuous pressure stress to be applied to the fingers,
thereby creating pain in the fingers.
