Abstract

There is some evidence that repetitive transcranial magnetic stimulation (rTMS) can alleviate the experience of chronic pain. The mechanisms by which rTMS may induce pain relief, however, are unknown. The present study examined whether a session of rTMS would produce sensory threshold changes in healthy individuals. Detection and pain thresholds for cold sensations were compared following low frequency (1 Hz) (Experiment 1) and high frequency (20 Hz) (Experiment 2) repetitive TMS. While cold detection threshold was significantly lowered by both rTMS rates, only high frequency rTMS produced a significant change in cold pain threshold. In contrast, sham rTMS did not alter thresholds for cold stimuli. These findings provide evidence that sensory thresholds can be influenced by repetitive transcranial magnetic stimulation.

摘要

有证据表明,重复经颅磁刺激(rTMS)可以缓解慢性疼痛。然而,rTMS缓解疼痛的机制尚不清楚。本研究调查了一次rTMS是否会使健康个体的感觉阈值发生变化。在低频(1Hz)(实验1)和高频(20Hz)(实验2)重复经颅磁刺激后,比较了冷觉的检测阈值和疼痛阈值。虽然两种rTMS频率都显著降低了冷觉检测阈值,但只有高频rTMS使冷痛阈值产生了显著变化。相比之下,伪rTMS并未改变冷刺激的阈值。这些发现证明感觉阈值会受到重复经颅磁刺激的影响。
