Abstract
PURPOSE: This study examined the changes in the kinematic variables during walking on a downhill ramp according to the shoe heel height.
METHODS: The subjects were 10 adult women with no history of musculoskeletal disorders who agreed to participate in the study. Data were collected using a motion analysis system (VICON) consisting of six infrared cameras. The slope was 120 ㎝ in width, 200 ㎝ in length, and 15 in inclination. To confirm the change in gait parameters (stride length, gait speed) and lower extremity joint angle according to the heel heights of the shoes, flat, 5 ㎝, and 10 ㎝ heel shoes were prepared and walked alternately.
RESULTS: As a result, both the stride length and walking speed showed significant differences according to the heel height between flat and 10 ㎝ (p<.05). In the sagittal plane, there was no significant difference in the hip joint and knee joint, but a significant difference was observed in all events in the ankle joint on all heel heights (p<.05). In particular, the heel strike and mid stance events showed significant differences among all height conditions (p<.05). No significant difference was observed in any of the joint angle changes in the frontal plane (p>.05).
CONCLUSION: As the shoe heel height increased, the instability increased and efforts to secure the stability were made, leading to a shortened stride length, walking speed, and angle of the ankle joint.
