Dorsal root ganglion stimulation (DRGS) has become a popular neuromodulatory treatment for neuropathic pain. We used magnetoencephalography (MEG) to investigate potential biomarkers of pain and pain relief, based on the differences in power spectral density (PSD) during varying degrees of pain and how these oscillations change during DRGS-mediated pain relief.

背根神经节刺激对慢性疼痛患者的脊髓上作用

背根神经节刺激 (DRGS) 已成为治疗神经性疼痛的流行神经调节疗法。我们使用脑磁图 (MEG) 来研究疼痛和疼痛缓解的潜在生物标志物，基于不同程度疼痛期间功率谱密度 (PSD) 的差异以及这些振荡在 DRGS 介导的疼痛缓解期间如何变化。
