儿童倒走足底压力的分布特征研究

为探讨倒走锻炼相对于正常向前行走在足底压力分布方面的特征，对12名 健康男性小学生正、倒走足底压力分布进行采集. 然后对足底10个区的最大压力和冲量进行 分析. 结果表明，儿童正、倒走足底压力分布差异明显. 与正走相比，倒走时足弓、 第4,5趾骨区的压力均变为较高压力区域，而大拇指、第1,2趾骨区变为较低压力区域. 该结果提 示，倒走足底压力分布特征可能是倒走所具有的锻炼、康复特殊效果主要原因之一.

PLANTAR PRESSURE DISTRIBUTIONS OF CHILDREN DURING BACKWARD WALKING

It was believed that plantar pressure might play an important role in the beneficial effect of backward walking exercise on health. Plantar pressure distributions of 12 healthy boys during normal and backward walking were collected. The sampling rate was 250\,Hz. The maximum force, pressure, and impulse of different regions during backward and normal walking were compared. The plantar foot plane is divided into 10 regions, including first, 2nd, 3rd, 4th, 5th metatarsal head (MTH), great toe (GT), lesser toes (LT), midfoot (MF), lateral heel (LH), medial heel (MH). The plantar pressure distributions of normal and backward walking were found significantly different. Compared with normal walking, the loading of the MF, 4th, and 5th MTH during backward walking were significantly greater, whereas those of the first and 2nd MTH were significantly smaller. These results suggest that plantar pressure distributions during backward walking may contribute to the improvement effects of backward walking exercise in fitness and rehabilitation.
