Joint range of motion based on the neutral null method, muscle strength based on manual muscle testing, and selective voluntary motor control based on selective control assessment of the lower extremity are standard parameters of a pediatric three-dimensional clinical gait analysis. Lower-limb reference data of children are necessary to identify and quantify abnormalities, but these are limited and when present restricted to specific joints or muscles.
This is the first study that encompasses the aforementioned parameters from a single group of 34 typically developing children aged 5-17 years. Left and right values were averaged for each participant, and then the mean and standard deviation calculated for the entire sample. The data set was tested for statistical significance ( < 0.05).
Joint angle reference values are mostly consistent with previously published standards, although there is a large variability in the existing literature. All muscle strength distributions, except for M. quadriceps femoris, differ significantly from the maximum value of 5. The mean number of repetitions of heel-rise test is 12 ± 5. Selective voluntary motor control shows that all distributions, except for M. quadriceps femoris, differ significantly from the maximum value of 2.
Since typically developing children do not match expectations and reference values from the available literature and clinical use, this study emphasizes the importance of normative data. Excessively high expectations lead to typically developing children being falsely underestimated and affected children being rated too low. This is of great relevance for therapists and clinicians.
基于中立零点法的关节活动范围、基于徒手肌力测试的肌肉力量以及基于下肢选择性控制评估的选择性随意运动控制是小儿三维临床步态分析的标准参数。儿童下肢参考数据对于识别和量化异常情况很有必要，但这些数据有限，且目前仅限于特定关节或肌肉。
这是第一项对34名年龄在5至17岁的正常发育儿童进行上述参数研究的实验。对每位参与者的左右侧数值取平均值，然后计算整个样本的均值和标准差。对数据集进行统计学显著性检验（<0.05）。
关节角度参考值大多与先前发表的标准一致，尽管现有文献中存在较大差异。除股四头肌外，所有肌肉力量分布均与最大值5有显著差异。提踵试验的平均重复次数为12±5。选择性随意运动控制表明，除股四头肌外，所有分布均与最大值2有显著差异。
由于正常发育儿童与现有文献及临床应用中的预期和参考值不匹配，本研究强调了规范数据的重要性。过高的期望会导致正常发育儿童被错误低估，而受影响儿童的评分过低。这对治疗师和临床医生具有重要意义。
