Description

[Purpose] We examined the movements of the lower leg, calcaneus and forefoot during gait and analyzed the relations of each segment in the limb, the relations with right and left leg movements of each subject, and the relations with arch height ratio. [Subjects] We examined 23 legs of 12 healthy adult males. [Method] Using a 3D motion analysis system, we measured the gait of subjects at their chosen walking speed. The analysis focused on varus and valgus of the movement. [Results] Regarding the relationships of each segment in the same limb, there was no correlation between heel valgus immediately after initial contact and forefoot valgus in the late stance phase. There was a high correlation in each individual between the movements of the left and right calcaneus as well as both forefeet. There was no correlation between the arch height ratio and calcaneus valgus or forefoot valgus. [Conclusion] There are a variety of movements of the foot during gait; however, from the results we understand that there is symmetry of movement in the right and left legs of an individual.<br>
