플립-플롭(Flip-flops) 보행이 건강한 성인의 시-공간적 변수와 발목 관절 움직임에 미치는 영향 = Effects of Wearing the Flip-flops on Spatio-temporal Gait Parameter and Ankle Motion in Healthy Young Individuals

다국어 초록 (Multilingual Abstract)

Background: The flip-flop, popular for its light design and convenience, has practical advantages, but is unstable compared to closed shoes. This feature of the flip-flop causes a change in walking patterns. In previous studies, there are many studies on the kinetic and kinematic characteristics of flip-flop walking; however, there are various conclusions on the effect of flip-flop walking on temporal and spatial parameters, and ankle motion change during flip-flop walking.
Objectives: The purpose of this study was to investigate the effect of flip-flop walking on spatio-temporal variables and ankle motion compared to sneakers walking.
Methods: Twenty-one healthy subjects were participated. Xsens-DOT was used to track body movements. Steplab was used to analyze, visualize, and quantify tracked data. Participants were instructed to walk naturally in sneakers that fit their feet, and 50 steps were measured, five steps later for adaptation. In the same way, the measurement was performed wearing flip flops. The paired t-test was used to investigate the difference between sneakers walking and flip-flop gait. Statistical significance levels were set to α = 0.05.
Results: There was no statistically significant difference in walking speed and stride length in spatio- temporal parameter. However, compared to sneakers walking, the maximum toe distance during flip-flop walking decreased statistically significantly (p < 0.05). The ankle motion was significantly reduced in both toe off angle and heel contact angle during flip-flop walking (p < 0.05).
Conclusions: Walking wearing flip-flops increases the risk of falls and reduces push off capacity. Therefore, people who are fatal to falls and vulnerable to fatigue should not walk wearing flip-flops.
