Many women wearing high-heeled footwear are at high risk of falls. Past studies have examined the balance on level ground or balance during walking. We measured the standing balance on the ground and side slopes for 18 healthy women.
Body sway was evaluated based on the center of pressure (COP) while participants stood on level ground on a side slope. The total locus length as well as rectangular and outer peripheral areas were then measured using a Zebris system. Measurements were compared under bare feet, normal shoe, and high-heeled shoe conditions.
On level ground, there were no significant differences among the three conditions. On the side slope, the total locus length (TLL), rectangular area (RA) and outer peripheral areas (OPA) were significantly greater for the high-heeled shoes than for the bare feet and normal shoes. Standing on the side slope caused larger body sway than on the level ground, along with a higher risk of falling.
In TLL, OPA, and RA, the COP moved outside substantially when participants stood on a slope in high heels than in shoes. High heels were highly unstable for standing on a slope since the ankle joint of one leg is in plantar flexion, the foot is pronated, and the other side is plantarflexed at the ankle with pronation of the foot.
High-heeled shoes significantly alter a person's balance when standing on a side slope, suggesting a high risk of falling.
许多穿高跟鞋的女性都有跌倒的高风险。过去的研究已经检查了在平地或行走时的平衡。我们测量了 18 名健康女性在平地和侧坡上的站立平衡。
参与者站在侧坡上的平地上时，根据压力中心 (COP) 评估身体摆动。然后使用 Zebris 系统测量总轨迹长度以及矩形和外周区域。在赤脚、正常鞋和高跟鞋条件下进行了比较。
在平地上，三种条件之间没有显着差异。在侧坡上，高跟鞋的总轨迹长度 (TLL)、矩形面积 (RA) 和外周面积 (OPA) 明显大于赤脚和正常鞋。站在侧坡上比站在平地上会导致更大的身体摆动，跌倒的风险更高。
在 TLL、OPA 和 RA 中，当参与者穿着高跟鞋站在斜坡上时，COP 明显向外移动。高跟鞋在斜坡上站立非常不稳定，因为一只腿的踝关节处于跖屈位，脚处于旋前位，另一侧踝关节处于跖屈位，脚处于旋前位。
高跟鞋在人站在侧坡上时会显着改变其平衡，表明跌倒的风险很高。
