The objective of study was to compare biomechanical parameters between normal and arch building gait in healthy subjects. A total of 40 feet from 20 healthy adults were evaluated in this study. The participants were asked to walk on a treadmill comfortably at 2 km/hr for 30 seconds. Then, they were asked to walk after making arch building through raising arches with their feet by pulling the big toe toward the heel. Gait parameters such as geometry, center of pressure, maximum force, and maximum pressure were measured in normal and the arch building gait using a gait analysis system equipped with pressure sensor. Arch building gait demonstrated significantly (p<0.01) decreased forefoot maximum force but significantly (p=0.024) increased heel maximum force compared to normal gait. Maximum pressures of the midfoot and heel were also significantly (both p<0.01) increased. However, the maximum pressures of the forefoot were not significantly (p>0.05) different between the two conditions. Geometry, phase, and time parameters were not significantly (p>0.05) different between the two conditions, either. Although forefoot and midfoot maximum force were significantly decreased in arch building gait compared to those in normal gait, the maximum pressure of forefoot was not significantly changed, indicating decreased area of forefoot contact during arch building gait. The arch building gait moves the center of presser to the hind foot and redistributes the contact area, thus changing the distribution of maximum pressure.
