Low back pain (LBP) is a global issue involving biological, psychological, and social factors. Pain-related fear has been shown to influence movement behavior, however, its association with some measures of movement behavior, such as spinal movement variability, remains inconclusive. To further investigate this, spinal kinematics during various activities of daily living (i.e., walking, running, lifting, and stair climbing) of 49 patients with chronic LBP and a group of 51 sex-, age-, and BMI-matched healthy controls were used to calculate lumbar spine movement variability which was quantified using different indices (i.e., coefficient of variation, coupling angle variability in vector coding, deviation phase of the continuous relative phase and an angle-angular velocity variability). General and task-specific pain-related fear was assessed using the Tampa Scale of Kinesiophobia and the Photograph Series of Daily Activities-Short Electronic Version, respectively. Linear regression analyses showed no significant association between movement variability and pain-related fear, however, the sample consisted of younger individuals with moderate disability and with low levels of pain and pain-related fear. In addition, the different variability indices were weakly correlated and varied greatly depending on the method used and the task performed. Therefore, comparisons between studies with different movement variability calculation methods or different activities should be treated with caution.
腰痛（LBP）是一个涉及生物、心理和社会因素的全球性问题。与疼痛相关的恐惧已被证明会影响运动行为，然而，其与一些运动行为指标（如脊柱运动变异性）之间的关联仍无定论。为了进一步研究这一点，对49例慢性腰痛患者和51名性别、年龄和体重指数匹配的健康对照者在各种日常生活活动（即行走、跑步、提举和爬楼梯）期间的脊柱运动学进行分析，以计算腰椎运动变异性，该变异性使用不同指标（即变异系数、矢量编码中的耦合角变异性、连续相对相位的偏差相位和角-角速度变异性）进行量化。分别使用坦帕运动恐惧量表和日常活动照片系列-简短电子版评估一般和特定任务的与疼痛相关的恐惧。线性回归分析显示运动变异性与与疼痛相关的恐惧之间无显著关联，然而，样本由残疾程度中等、疼痛及与疼痛相关的恐惧水平较低的年轻个体组成。此外，不同的变异性指标之间相关性较弱，并且根据所使用的方法和执行的任务而有很大差异。因此，对采用不同运动变异性计算方法或不同活动的研究进行比较时应谨慎对待。
