The aim of this study was to compare training effects on postural control using two different unstable shoe constructions.
Twenty-nine healthy subjects participated in this study and were randomly divided into three groups. Two experimental groups (10 subjects in each group) were assigned to a 6 week training program of specific sensorimotor exercises with unstable shoe constructions, one group using MBT(®) shoes and one group wearing Reflex Control(®) shoes (RC). Subjects in the control group (9 subjects) did not perform balance training.
Postural control was measured in one-leg stance in two testing conditions. We recorded postural sway on a force plate (static testing situation) and displacements of a moveable platform (dynamic testing situation) before and after the training period.
There were no effects of training with unstable shoe constructions on postural sway in the static testing condition (for comparison of groups: p = 0.990 and p = 0.119). However, the RC group showed statistically significant improvements in the dynamic testing situation (p = 0.014 compared to control subjects). In the MBT group improvements were not significantly different in comparison to control group (p = 0.518).
Our results indicate that exercises using unstable shoe constructions, particularly the RC, improve postural control only in dynamic conditions.
本研究旨在比较两种不同不稳定鞋结构在姿势控制训练效果上的差异。
29 名健康受试者参与了本研究，并随机分为三组。两个实验组（每组 10 名受试者）接受了为期 6 周的特定感觉运动练习与不稳定鞋结构的训练计划，一组使用 MBT（®）鞋，一组穿着 Reflex Control（®）鞋（RC）。对照组（9 名受试者）未进行平衡训练。
在两种测试条件下测量单腿站立时的姿势控制。我们在力板上记录姿势摆动（静态测试情况）和可移动平台的位移（动态测试情况），并在训练前后进行测量。
不稳定鞋结构的训练对静态测试条件下的姿势摆动没有影响（组间比较：p=0.990 和 p=0.119）。然而，RC 组在动态测试情况下表现出统计学上显著的改善（与对照组相比，p=0.014）。MBT 组与对照组相比，改善程度无显著差异（p=0.518）。
我们的结果表明，使用不稳定鞋结构的练习，特别是 RC，可以仅在动态条件下改善姿势控制。
