  • 在包括慢性疼痛患者在内的各种参与者群体中验证拟议的基于EEG的指标.

主要方法:

  • 收集了健康参与者 (带有和没有诱导疼痛) 和慢性疼痛患者的EEG数据.
  • 利用希尔伯特变换来提取EEG信号的上层外.
  • 计算了β频段 (Piqβ) 上层包裹的平均变化系数作为疼痛指标.

主要成果:

  • 建立了10%的Piqβ值来表明疼痛的存在 (Piqβ≥10%).
  • 在较高的Piqβ值和疼痛强度增加之间有直接的相关性.
  • 通过Piqβ测量成功识别和量化慢性疼痛患者的疼痛.

结论:

  • Piqβ作为基于EEG的客观指标,用于识别和量化慢性疼痛患者的疼痛.
  • 这种神经生理学测量为客观疼痛评估提供了有价值的工具,支持临床决策和疼痛管理.
  • Piqβ的发展有助于推进客观疼痛监测和治疗策略.
