Abstract

Objective

The primary objective was to compare the difference in autonomic nervous system (ANS) response between motor imagery (MI) group and action observation (AO) group. Both consisted of two subgroups: the control subgroup (CG), which consisted of asymptomatic individuals, and the patient subgroup (PG), which consisted of patients with chronic low back pain (CLBP). The secondary objective was to assess ANS activity during AO and MI training according to the fear-of-movement levels of the PGs.

Methods

Sixty participants were randomly assigned. The autonomic outcome measures included skin conductance (SC), respiration rate (RR), and heart rate (HR).

Results

Results showed that intergroup differences in RR were higher in the PG, with a large effect size (p = .007, d = 1.71). Only the PGs showed intragroup differences in SC (p <.05). In terms of ANS activity during the training, there were no statistically significant intergroup differences (p <.05). However, the strongest intragroup differences were among the AO_PG with greater levels of kinesiophobia. For the SC and HR variables, only this condition showed significant differences between baseline and the first and second movements, with a large effect size (p <.001 and p = .002, respectively, and d >.80).

Conclusions

The results showed that AO and MI training in the PG and CG resulted in similar but not identical ANS activation, with slightly higher activation in the PG. The differences in the PG could be associated with kinesiophobia when visually exposed to low-back movements that could be interpreted as hazardous or unsafe.

健康个体和慢性腰痛患者运动表征过程中自主神经系统反应的比较分析：一项前瞻性队列研究

摘要

客观的

主要目的是比较运动想象 (MI) 组和动作观察 (AO) 组之间自主神经系统 (ANS) 反应的差异。两者都由两个亚组组成：控制亚组 (CG)，由无症状个体组成，患者亚组 (PG)，由慢性腰痛 (CLBP) 患者组成。次要目标是根据 PG 的运动恐惧程度评估 AO 和 MI 训练期间的 ANS 活动。

方法

60 名参与者被随机分配。自主神经结果测量包括皮肤电导 (SC)、呼吸率 (RR) 和心率 (HR)。

结果

结果显示 PG 的 RR 组间差异更大，效应量大（p = .007，d  = 1.71）。只有 PG 显示出 SC 的组内差异 ( p <.05)。就训练期间的 ANS 活动而言，没有统计学上显着的组间差异 ( p <.05)。然而，最强的组内差异出现在具有更高程度的运动恐惧症的 AO _PG中。对于 SC 和 HR 变量，只有这种情况在基线与第一次和第二次运动之间显示出显着差异，具有较大的影响大小（分别为p <.001 和p = .002，d > .80）。

结论

结果表明 PG 和 CG 中的 AO 和 MI 训练导致相似但不相同的 ANS 激活，PG 中的激活略高。当视觉上暴露于可能被解释为危险或不安全的下背部运动时，PG 的差异可能与运动恐惧症有关。
