特发性脚趾行走(ITW)，在3岁后被认为是异常的，是医学专业人员，特别是骨科外科医生和理疗师常见的症状。特发性足趾行走的分类将有助于更好地了解病情，区分真正的特发性足趾行走者与其他情况的患者，并允许分配严重程度分级，从而指导ITW的治疗。这项研究的目的是描述特发性脚趾行走，并在大样本儿童中开发脚趾行走分类方案。三个主要标准，存在第一个脚踝摇摆，存在早期第三个脚踝摇摆，和主要的早期踝关节时刻，被用来将特发性脚趾行走分为三个严重组：类型1轻度；类型2中度；类型3重度。还分析了基于踝关节活动范围、矢状面关节功率、膝关节运动学和肌电数据的支持数据。对133例特发性足趾行走儿童(266足)的前瞻性步态分析数据进行分析。受试者年龄范围为4.19~15.96岁，平均8.80岁。合并右足和左足数据，40只脚被归类为1型，129只被归类为2型，90只被归类为3型。7只脚无法分类。对构成主要标准的连续变量的统计分析表明，脚趾行走严重程度分类能够区分脚趾行走严重程度的三个级别。这种分类可以定量描述特发性脚趾行走模式，并可以描述三种不同类型的ITW患者(轻度、中度和重度)。(C)2006爱思唯尔B.V.保留所有权利。
Idiopathic toe walking (ITW), considered abnormal after the age of 3 years, is a common complaint seen by medical professionals, especially orthopaedic surgeons and physiotherapists. A classification for idiopathic toe walking would be helpful to better understand the condition, delineate true idiopathic toe walkers from patients with other conditions, and allow for assignment of a severity gradation, thereby directing management of ITW. The purpose of this study was to describe idiopathic toe walking and develop a toe walking classification scheme in a large sample of children. Three primary criteria, presence of a first ankle rocker, presence of an early third ankle rocker, and predominant early ankle moment, were used to classify idiopathic toe walking into three severity groups: Type 1 mild; Type 2 moderate; and Type 3 severe. Supporting data, based on ankle range of motion, sagittal joint powers, knee kinematics, and EMG data were also analyzed. Prospectively collected gait analysis data of 133 children (266 feet) with idiopathic toe walking were analyzed. Subjects' age range was from 4.19 to 15.96 years with a mean age of 8.80 years. Pooling right and left foot data, 40 feet were classified as Type 1, 129 were classified as Type 2, and 90 were classified as Type 3. Seven feet were unclassifiable. Statistical analysis of continuous variables comprising the primary criteria showed that the toe walking severity classification was able to differentiate between three levels of toe walking severity. This classification allowed for the quantitative description of the idiopathic toe walking pattern as well as the delineation of three distinct types of ITW patients (mild, moderate, and severe).
