초록

Purpose: The purpose of this study is to compare lower extremity muscle activities and ankle joint angles between differentfoot strike patterns (forefoot strike, heelfoot strike) during stair ascent walking.
Methods: The subjects of this study were 22 males who walked in each foot strike pattern on ascent stairs at a speed of 85beats/min. During stair walking with the two types of foot strike patterns, the muscle activities of the rectus femoris, tibialis anterior,medial gastrocnemius, hamstring, and gluteus medius were measured. Additionally, ankle joint angles for inversion, eversion,dorsi flexion, and plantar flexion were recorded. Each participant underwent the experiment three times, with the foot strike patternrandomized. Results were averaged according to the foot strike pattern.
Results: Significant differences in ankle angles were observed across all phases according to foot strike pattern. Muscle activitiesin the lower extremities showed significant differences in all phases except the swing 1 phase. Moreover, differences in footmovement trajectory were noted depending on the foot strike pattern.
Conclusion: Walking on ascent stairs elicited differences in lower extremity muscle activities and ankle joint anglesbased on foot strike pattern. These findings can serve as foundational data for selecting a suitable foot strike patterntailored to individual patient conditions when training patients in walking on ascent stairs.
