Intensity of contralateral associated movements (AMs) is a measure of movement quality assessed using frequency and degree of AMs. A sample of 593 right-handed participants without disability (286 males, 307 females; aged 5y-18y 6mo) was studied with the Zurich Neuromotor Assessment (ZNA). The ZNA is a standardized testing procedure which assesses performance on standardized motor tasks according to timed performance and frequency and degree of AMs. In contrast to frequency and degree, intensity of AMs allowed the calculation of centiles which were quasi-continuous. Centile curves of contralateral AMs for the ZNA and data on inter- and intraobserver reliability are presented. The significance of age, sex, and side differences are discussed. Intensity of AMs offers clinical and scientific advantages for measurement of movement quality. There is a decrease of AMs with age depending on the complexity of tasks. Females showed consistently fewer AMs than males, whereas only minor side differences were shown.
对侧关联运动（AMs）的强度是一种通过AMs的频率和程度来评估运动质量的指标。使用苏黎世神经运动评估（ZNA）对593名无残疾的右利手参与者（286名男性，307名女性；年龄5岁至18岁6个月）进行了研究。ZNA是一种标准化测试程序，根据定时表现以及AMs的频率和程度来评估标准化运动任务的表现。与频率和程度不同，AMs的强度允许计算近似连续的百分位数。给出了ZNA对侧AMs的百分位数曲线以及观察者间和观察者内信度的数据。讨论了年龄、性别和侧别差异的意义。AMs的强度在运动质量测量方面具有临床和科学优势。根据任务的复杂性，AMs会随着年龄增长而减少。女性的AMs始终比男性少，而仅显示出较小的侧别差异。
