Increased plantar cutaneous afferent information may improve postural control.
To compare postural control measures between balance conditions with and without textured insoles.
crossover trial.
Research Laboratory.
33 healthy subjects (27.4 +/- 9.1 yrs, 172.6 +/- 10.3 cm, 75.4 +/- 16.4 kg).
INTERVENTION(S): Subjects performed 24, 10-second bipedal and unilateral stance balance trials with eyes opened and eyes closed, with and without a textured insole in subjects' shoes.
Average velocity and area of center of pressure (COP) excursions.
We observed an interaction among balance conditions during bilateral stance, but not during unilateral stance. On average, subjects exhibited greater area and velocity of COP excursions with eyes closed compared to eyes opened. Significant differences in area and velocity of COP excursions were observed during bilateral stance only when subjects were not wearing textured insoles. There were no significant differences while subjects balanced in bilateral stance with textured insoles.
Increased afferent information from textured insoles improves postural control in bilateral stance.
增加足底皮肤传入信息可能会改善姿势控制。
比较使用和不使用纹理鞋垫时平衡状态下的姿势控制测量结果。
交叉试验。
研究实验室。
33名健康受试者（27.4±9.1岁，172.6±10.3厘米，75.4±16.4千克）。
受试者进行24次、每次10秒的双足和单足站立平衡试验，试验时睁眼和闭眼，鞋子穿或不穿纹理鞋垫。
压力中心（COP）偏移的平均速度和面积。
我们观察到双侧站立时平衡状态之间存在相互作用，但单足站立时没有。平均而言，与睁眼相比，受试者闭眼时COP偏移的面积和速度更大。仅在受试者不穿纹理鞋垫时，双侧站立期间观察到COP偏移的面积和速度存在显著差异。当受试者穿着纹理鞋垫进行双侧站立平衡时，没有显著差异。
来自纹理鞋垫的传入信息增加可改善双侧站立时的姿势控制。
