Abstract
Abstract To clarify the magnitude of shape change during walking, the shapes of four cross-sections (Forefoot, Instep, Navicular, and Heel) of the right foot during standing and walking were measured using a four-dimensional measurement system we developed (14 Hz) with an accuracy of ±0.5 mm. Images of the sole were measured using a high-speed video camera (120 Hz). Cross-section shapes and derived dimensions were compared between the standing condition, first peak (P1), and midstance valley of two peaks (MSV) of vGRF during walking. Heel and Navicular cross-sections were more laterally inclined during walking than during standing by 6° on average. Compared to a...
