Objective: The aim of this study was to investigate the effects of forefoot rocker bottom shoes with metatarsal bar on gait during the stance phase of human walking. Background: In recent years, many studies related to various functional shoes have been conducted. One of the most important factors in developing the functional shoes for more efficient gait is the shoe outsole. As metatarsal bar transform the shape of the outsole as well as take forefoot rocker, more specific research related to the effects of shoe outsole structure and metatarsal bar on gait is needed. Method: Ten healthy young females participated in this study as the subjects. Each subject walked on a treadmill at a speed of 3km/h for 1 minute while under the following conditions: (1) with normal shoes and (2) with forefoot rocker bottom shoe with metatarsal bar. Muscle activities of four muscles (rectus femoris, biceps femoris, tibialis anterior, and medial gastrocnemius) were acquired by the surface electrodes, and these data were rectified and normalized to the average activity to determine relative changes in muscles during walking. Also, plantar pressure distributions were obtained by using the Pedar Insole-system and various pressure parameters (force, peak pressure, and mean pressure) were analyzed during the stance phase of walking. Results: Muscle activity in rectus femoris, biceps femoris, and medial gastrocnemius decreased significantly (p < 0.05) from initial contact to terminal stance while tibialis anterior activity decreased insignificantly during initial contact and loading response, and medial gastrocnemius activity increased during terminal stance when wearing forefoot rocker bottom shoe with metatarsal bar. The force and mean pressure increased significantly (p < 0.05) while peak pressure decreased significantly (p < 0.05) during the stance phase of gait. Conclusion: The structure of the forefoot rocker bottom shoe with metatarsal bar can help to push the ground efficiently during walking and to walk more comfortably by reducing the fatigue of muscle and reliving the peak pressure. Application: This paper might help to design the structure of shoes and evaluate various functional shoes for more efficient gait.
