Abstract

Objective

This study aims to explores the physiological and psychological mechanisms of exercise-induced hypoalgesia (EIH) by combining the behavioral results with neuroimaging data on changes oxy-hemoglobin (HbO) in prefrontal cortex (PFC).

Methods

A total of 97 healthy participants were recruited and randomly divided into three groups: a single dance movement therapy (DMT) group, a double DMT group, and control group. Evaluation indicators included the pressure pain threshold (PPT) test, the color-word stroop task (CWST) for wearing functional near-infrared spectroscopy (fNIRS), and the self-assessment manikin (SAM). The testing time is before intervention, after intervention, and one hour of sit rest after intervention.

Results

1) Repeated measures ANOVA revealed that, there is a time * group effect on the PPT values of the three groups of participants at three time points. After 30 min of acute dance intervention, an increase in the PPT values of 10 test points occurred in the entire body of the participants in the experimental group with a significant difference than the control group. 2) In terms of fNIRS signals, bilateral DLPFC and left VLPFC channels were significantly activated in the experimental group. 3) DMT significantly awakened participants and brought about pleasant emotions, but cognitive improvement was insignificant. 4) Mediation effect analysis found that the change in HbO concentration in DLPFC may be a mediator in predicting the degree of improvement in pressure pain threshold through dance intervention (total effect β = 0.7140).

Conclusion

In healthy adults, DMT can produce a diffuse EIH effect on improving pressure pain threshold, emotional experience but only showing an improvement trend in cognitive performance. Dance intervention significantly activates the left ventrolateral and bilateral dorsolateral prefrontal cortex. This study explores the central nervous system mechanism of EIH from a physiological and psychological perspective.

舞蹈动作疗法的镇痛效果：一项 fNIRS 研究。

研究目的本研究旨在通过将行为学结果与前额叶皮质氧血红蛋白（HbO）变化的神经影像学数据相结合，探讨运动诱导低痛感（EIH）的生理和心理机制：方法：共招募了 97 名健康参与者，并将其随机分为三组：单人舞蹈动作疗法（DMT）组、双人舞蹈动作疗法组和对照组。评价指标包括压痛阈值（PPT）测试、佩戴功能性近红外光谱仪（fNIRS）的彩色文字笔划任务（CWST）和自我评估人体模型（SAM）。测试时间为干预前、干预后和干预后静坐休息一小时：1）重复测量方差分析显示，三组参与者在三个时间点的 PPT 值存在时间 * 组别效应。经过 30 分钟的急性舞蹈干预后，实验组参与者全身的 PPT 值增加了 10 个测试点，与对照组相比差异显著。2) 在 fNIRS 信号方面，实验组的双侧 DLPFC 和左侧 VLPFC 通道被显著激活。3) DMT 能明显唤醒参与者并带来愉悦的情绪，但认知能力的改善并不明显。4）中介效应分析发现，DLPFC 中 HbO 浓度的变化可能是预测舞蹈干预对压痛阈值改善程度的中介因素（总效应 β = 0.7140）：结论：在健康成年人中，DMT可产生弥漫性EIH效应，改善压痛阈值和情绪体验，但仅表现出认知能力的改善趋势。舞蹈干预能明显激活左侧腹外侧和双侧背外侧前额叶皮层。本研究从生理学和心理学角度探讨了 EIH 的中枢神经系统机制。

期刊介绍： NeuroImage, a Journal of Brain Function provides a vehicle for communicating important advances in acquiring, analyzing, and modelling neuroimaging data and in applying these techniques to the study of structure-function and brain-behavior relationships. Though the emphasis is on the macroscopic level of human brain organization, meso-and microscopic neuroimaging across all species will be considered if informative for understanding the aforementioned relationships.
