PURPOSE
To examine the effects of different torsional flexibilities of shoes on gait and stability in children who are newly walking.
METHODS
Twenty-five children walking 5 months or less were evaluated barefoot and in 4 shoes with different torsional flexibilities (UltraFlex, MidFlex, LowFlex, and Stiff). Gait pattern was assessed using GaitMatII. Stability was determined by the number of stumbles/falls during functional tasks.
RESULTS
Stance time was shorter barefoot compared with all shoe conditions (P = .000). Stance time was shorter in UltraFlex than in LowFlex (P = .000). Step width was wider in UltraFlex than in MidFlex and LowFlex (P = .028). Velocity, step length, and the number of stumbles/falls did not differ significantly across shoe conditions. Children walking for 2 months or less had significantly more stumbles and falls than children walking more than 2 months (P = .003).
CONCLUSIONS
Stance time and step width differ across shoe conditions. Stability does not differ across shoe conditions.
目的
研究不同扭转灵活性的鞋子对刚开始学步儿童步态及稳定性的影响。
方法
对25名学步时间在5个月及以内的儿童进行评估，分别为赤脚状态以及穿着4种具有不同扭转灵活性的鞋子（超灵活型、中等灵活型、低灵活型和僵硬型）进行评估。使用GaitMatII评估步态模式。通过功能性任务期间绊倒/跌倒的次数来确定稳定性。
结果
与所有穿鞋状态相比，赤脚时的站立时间更短（P = .000）。超灵活型鞋子的站立时间比低灵活型鞋子短（P = .000）。超灵活型鞋子的步宽比中等灵活型和低灵活型鞋子宽（P = .028）。不同鞋子状态下的速度、步长和绊倒/跌倒次数无显著差异。学步2个月及以内的儿童比学步超过2个月的儿童绊倒和跌倒次数显著更多（P = .003）。
结论
不同鞋子状态下站立时间和步宽存在差异。不同鞋子状态下稳定性无差异。
