背景：翻转鞋被认为提供了一个增强的表面，身体可以更容易地滚动。本研究的目的是调查翻转鞋的影响上的翻转功能的步行。方法：20名受试者走在三个条件：（i）MBT鞋（马赛赤脚技术）的特点是一个坚硬的鞋底在前后方向圆形;（ii）替代翻转鞋（Scholl STARLIT的原型）的特点是前后方向呈圆形的坚硬鞋底;（iii）扁平控制鞋。收集下肢运动学和地面反作用力数据。以下肢侧倾形状半径和末端双肢支撑持续时间表征步行的侧倾功能。结果：在3种鞋型条件下，足-鞋、踝-足和膝-踝-足翻转形状的整体和中部半径均显著小于（P < 0. 05），而弯曲鞋底半径与翻转形状半径的关系显著小于（P < 0. 05）。e.更弯曲）的MBT（范围从12%到81%小）和翻转鞋（范围从2%到69%小）与平底鞋相比（p < 0.05）。与平底鞋相比，MBT的双支撑时间显著减少了12%，翻转鞋减少了7%。结论：穿MBT鞋和翻转鞋时，足-鞋、踝-足和膝-踝-足翻转形状更弯曲，体重转移更快。然而，研究结果也表明，静态鞋底曲线不是唯一的因素影响步态摇杆功能。
Background: Rollover footwear is assumed to provide an enhanced surface over which the body can roll more easily. The aim of this study was to investigate the effects of rollover footwear on the rollover function of walking.Methods: Twenty subjects walked in three conditions: (i) a MBT shoe (Masai Barefoot Technology) characterized by a stiff sole rounded in the anterior-posterior direction; (ii) alternative rollover shoe (a prototype of Scholl STARLIT) characterized by a stiff sole rounded in the anterior-posterior direction; (iii) a flat control shoe. Data on the lower limb kinematics and ground reaction force were collected. The rollover function of walking was characterized using the radii of lower limb rollover shapes and duration of terminal double limb support. These data were compared between the three shoe conditions and the relationship between the radii of the curved shoe sole and the radii of the rollover shapes investigated.Results: The radii of the whole and middle part of foot-shoe, ankle-foot and knee-ankle-foot rollover shapes were significantly smaller (i. e. more curved) for MBT (ranging from 12% to 81% smaller) and the rollover shoe (ranging from 2% to 69% smaller) compared with flat shoe (p < 0.05). Double support time decreased significantly for MBT similar to 12% and rollover shoe similar to 7% compared to the flat shoe. For both MBT and rollover shoes, there were positive correlations (r = 0.42-0.60) between the sole radii and radius of foot-shoe rollover shape (p < 0.05).Conclusion: Wearing MBT and the rollover shoe resulted in more curved foot-shoe, ankle-foot and knee-ankle-foot rollover shapes and faster weight transfer. However, the results also indicate that static sole curve is not the only factor influencing the gait rocker function.
