One hundred twenty-four children with intoeing and 80 age-matched controls were investigated with the Kistler force plate. Tr2, reflecting the maximum external rotational ground reaction torque, is reduced by 30% to 40% in all intoeing children. There also is an appreciably shorter pathway of the point of application of the ground reaction force in the Y-direction (from 20% to 25%) and an obvious medial shift of the point of application of the ground reaction force in the X-direction (from 105% to 290%), from heel strike to toe-off as compared with controls. In spontaneous correction of intoeing, point of application of the ground reaction force in the X-direction becomes more close to normal. The "foot progression angle," which can easily be calculated from the force plate measurements to judge the degree of intoeing, is different from the values in the literature.
对124名内八字儿童和80名年龄匹配的对照组儿童使用奇石乐测力板进行了研究。反映最大外部旋转地面反作用力矩的Tr2在所有内八字儿童中降低了30%至40%。与对照组相比，在足跟触地到足趾离地过程中，地面反作用力作用点在Y方向上的路径也明显缩短（从20%至25%），在X方向上地面反作用力作用点明显向内侧偏移（从105%至290%）。在内八字自然矫正过程中，地面反作用力在X方向上的作用点变得更接近正常。“足前进角”可根据测力板测量结果轻松计算得出，用于判断内八字程度，其与文献中的数值不同。
