This study is to investigate whether the dominance of the hand and leg influences the plantar pressure distribution in the standing position. The dominant hand and leg of 44 young people were studied and classified by using the HN and Chapman's test. There was a correlation between the dominant hand and leg, and 72% of the group having a right dominant leg showed a significant weight load on their left leg rather than on their right and the 41.2% of the group having a dominant left leg showed weight load on their left leg. 80% of the subjects who had a dominant right leg were classified as the LH type having the center of pressure (COP) in their left foot on their heel side and the COP in the right foot on their tip toe side. On the other hand, the percentage of the subjects having a dominant left leg classified to be of the LH type was 47.1% and was more than the percentage of the subjects of the same group classified to be of the opposite RH type (41.2% of the group). The weight load ratio and the COP position of the group having a dominant right leg indicated there is a clear role difference between the left and right side of the foot for balancing the body weight, whereas such a clear difference was not apparent in the group having a dominant left leg.
