Assessing pain perception through self-reports may not be possible in some patients, for example, sedated. Our group considered if facial electromyography (fEMG) could provide a useful alternative, by testing on healthy participants subjected to experimental pain. Activity of four facial muscles was recorded using fEMG alongside self-reported pain scores and physiological parameters. The pain stimulus elicited significant activity on all facial muscles of interest as well as increases in heart rate. Activity from two of the facial muscles correlated significantly against pain intensity. Pain perception can be assessed through fEMG on healthy participants. We believe that this model would be valuable to clinicians that need to diagnose pain perception in circumstances where verbal reporting is not possible.
通过自我报告评估疼痛感知在某些患者中可能不可行，例如镇静状态的患者。我们的团队考虑通过在接受实验性疼痛的健康参与者身上进行测试，看看面部肌电图 (fEMG) 是否可以提供一种有用的替代方法。在自我报告的疼痛评分和生理参数的同时，使用 fEMG 记录了 4 块面部肌肉的活动。疼痛刺激引起了所有感兴趣的面部肌肉的显著活动以及心率的增加。两块面部肌肉的活动与疼痛强度显著相关。健康参与者可以通过 fEMG 来评估疼痛感知。我们相信，对于那些在无法进行口头报告的情况下需要诊断疼痛感知的临床医生来说，这种模型将非常有价值。
