Abstract

Background

Motor control exercise is commonly applied in people with chronic low back pain (CLBP), but possibly not all people with CLBP have motor control impairments. We suggest movement precision as measure to identify motor control impairments. Movement precision has been operationalized as trunk movement variability (TMV) and as trunk tracking error(s) (TTE). Objectives: To compare the known-group validity and the responsiveness of TMV and TTE.

Design

We used a case-control comparison (Healthy controls (n = 30) vs CLBP (n = 60)) to assess the known-group validity. A cohort study, (measurements in week 3 and week 12 of treatment), was used to assess responsiveness.

Methods

TMV (temporal (CyclSD) and spatial (MeanSD)) was analyzed during standing, repetitive flexion and rotation tasks (35x). TTE was measured during movement target tracking tasks, again in flexion and rotation. Participants with CLBP followed a multidisciplinary intervention and both measures were assessed in week 3 and week 12 of treatment. 2-way MANOVA and 2-way ANOVA were used to assess the effect of Group (CLBP vs healthy controls) and direction (flexion vs rotation) on TMV and TTE. For responsiveness, 2-way MANOVA and 2-way ANOVA were used to assess the effect of treatment and direction on both measures.

Findings

At baseline, TMV was not different between groups, while TTE was higher in the people with CLBP (p = 0.005, n_p² = 0.09). Treatment strongly decreased temporal TMV (p = 0.025, n_p² = 0.33) and TTE (p < 0.001, n_p² = 0.844).

Conclusions

These results demonstrate that TTE is more sensitive to CLBP and more responsive to treatment than TMV.

慢性腰痛患者躯干运动的精确性

背景运动控制训练通常用于慢性腰背痛（CLBP）患者，但可能并非所有慢性腰背痛患者都有运动控制障碍。我们建议将运动精确度作为识别运动控制障碍的指标。运动精确度可操作为躯干运动变异性（TMV）和躯干跟踪误差（TTE）。研究目的设计我们采用病例对照比较法（健康对照组（n = 30）vs CLBP（n = 60））来评估已知组的有效性。方法在站立、重复性屈曲和旋转任务（35x）中分析TMV（时间（CyclSD）和空间（MeanSD））。在运动目标跟踪任务中测量了 TTE，同样是在屈曲和旋转时。CLBP患者在接受多学科干预后，在治疗的第3周和第12周对这两项指标进行评估。双向 MANOVA 和双向方差分析用于评估组别（CLBP vs 健康对照组）和方向（屈曲 vs 旋转）对 TMV 和 TTE 的影响。研究结果基线时，各组间的 TMV 无差异，而 CLBP 患者的 TTE 较高（p = 0.005，np2 = 0.09）。治疗后，颞叶 TMV（p = 0.025，np2 = 0.33）和 TTE（p < 0.001，np2 = 0.844）显著下降。
