One hundred twenty-four intoeing and 80 age-matched normal children were studied using the Kistler force plate. Intoeing gait was usually caused by increased femoral anteversion (IFA), internal tibial torsion (ITT), or metatarsus adductus (MAD). Thirty-five children showing spontaneous correction and a return to normal gait (COR) were singled out. Our results confirmed that there were variations of the ground reaction force (GRF) in three directions in the different groups, particularly in the vertical and medial-lateral components. Alterations of magnitude of GRF or duration of stance phase was found to be significant compared with normal subjects. On this basis, we suggest that dynamic forces are related to the remodeling of the epiphyseal plate or respond to actions of the plantar flexors, although we could not discern a specific correlation between them.
使用Kistler测力板对124名内八字儿童和80名年龄匹配的正常儿童进行了研究。内八字步态通常由股骨前倾增加（IFA）、胫骨内旋（ITT）或内收足（MAD）引起。挑选出35名显示自发矫正并恢复正常步态（COR）的儿童。我们的结果证实，不同组在三个方向上的地面反作用力（GRF）存在差异，特别是在垂直和内外侧分量上。与正常受试者相比，发现GRF大小或站立期持续时间的改变具有显著性。在此基础上，我们认为动力与骨骺板的重塑有关或对跖屈肌的作用有反应，尽管我们无法辨别它们之间的具体相关性。
