摘要

背景:许多通过心理手段研究疼痛减轻的研究混淆了认知因素和运动因素。我们进行了两个实验来研究有意识的运动能在多大程度上减轻实验性疼痛。方法在实验1中,测量非优势手在眼运动和手指运动两种运动条件下的冷压疼痛耐受性和强度。在实验2中,测量了视觉注意指向优势手和视觉注意指向受有害刺激的非优势手两种手指相互运动条件下的耐受性和强度。结果发现,当视觉注意力被引导到或远离有害刺激的空间位置时,对侧肢体手指的反向运动导致耐受性时间显著延长,疼痛强度评分显著降低。结论实验结果证实,对侧的肢体运动可以减轻实验性疼痛。需要进一步的研究来确定运动是否能减轻非实验性疼痛。

Contralateral limb movement modulates cold pressor pain

Background

Many studies investigating the attenuation of pain by psychological means have confounded cognitive factors with motoric factors. Two experiments were performed to investigate the extent to which intentional movements alone can attenuate experimental pain.

Methods

In experiment 1, tolerance and intensity of cold pressor pain administered to the non-dominant hand was measured for two movement conditions, reciprocal eye movements and reciprocal finger movements of the dominant hand. In experiment 2, tolerance and intensity was measured for two reciprocal finger movement conditions, when visual attention was directed to the dominant hand and when visual attention was directed to the location of the noxiously stimulated non-dominant hand.

Results

Reciprocal finger movements of the limb contralateral to a noxiously stimulated limb were found to result in significantly longer tolerance times and significantly lower pain intensity ratings when visual attention was directed to and away from the spatial location of the noxious stimulation.

Conclusion

These results confirm that movement of the limb contralateral to a noxiously stimulated limb attenuates experimental pain. Further research is required to ascertain whether movement alone attenuates non-experimental pain.
