팔자걸음 중년여성의 보행 중 다리근육의 활성도 및 보행 패턴의 변화

Abstract

This study investigates the changes in muscle activity of lower limb and walking pattern during gait in middle-aged women with toeing-out gait. Participants were assigned to toeing-out gait group (TOG, n=7) and control group (CON, n=9). TOG were recruited from greater than foot angle 15°. Both groups were measured for body composition (weight, body fat, BMI, WHR), muscle activity of lower limb (Vastus lateralis muscle; VL, Vastus medialis; VM, Tibialis anterior muscle; TA, Gastrocnemius lateralis muscle; GL) during gait and walking pattern (surface, foot angle, maximum pressure, average pressure, step duration). Muscle activity of VL(p.001), VM(p.05), TA(p.01) and GL(p.001) during gait showed significantly different between groups, respectively. Foot angle of left (p.01) and right (p.01) during gait showed s ignificantly different between groups, respectively. However, surface, maximum pressure, average pressure and step duration were not significantly different between groups, respectively. These results indicate that middle-aged women with toeing-out gait lead to the changes in muscle activity of lower limb during gait and it effect the foot angle.
