Abstract
With 22 healthy persons as subjects, we investigated the effect of measurement location on agility and synchronization of the upper limbs. The task was tapping as fast as possible and synchronous with a 4 Hz audible signal with both fingers and hands and we determined the tapping time interval and its variation. In comparison of the dominant and non-dominant side hands, the dominant hand values for tapping time interval and variation were significantly lower. There was no significant difference in tapping time interval in finger tapping, but the variation was significantly lower on the dominant side. The hand joints of the dominant side had lower tapping time intervals and variation than those of other locations. These results suggest that the dominant hand in hand tapping shows the best performance.
