正常人清醒和催眠状态下痛阈的自身对照研究

目的 研究健康正常人催眠静息状态和清醒安静状态痛阈差异，以及催眠敏感性与痛阈和痛阈变化的相关性。方法 用痛阈测试仪分别测定清醒安静状态和催眠静息状态的痛阈，比较两者的差异；用斯坦福敏感性量表C式测试受使者的敏感性。结果 催眠静息状态的痛阈明显高于清醒安静状态的痛阈（P=0．018）；催眠敏感性与催眠静息状态痛阈和痛阌变化成正相关（P〈0.01）。结论 催眠静息状态时的痛阈明显提高，痛阈增高可以作为催眠状态界定的一个客观指标。

A self comparison of the pain threshold of healthy people in the alert state and hypnotic state

Objective: To study the difference of pain threshold of healthy people in the alert state and hypnotic resting state , and the relationship of susceptibility to the baseline pain threshold and the change of pain threshold were analyzed. Methods: Healthy people underwent the assessments of susceptibility with Stanford Hypnotic Susceptibility Scale - C and pain threshold at the alert state, and pain threshold measurement at the hypnotic state . with the pain threshold machine. Their pain thresholds were compared between the two states,. Results: Pain threshold at hypnotic state was significantly increased when compared with that at alert state( P < 0. 05) , and the susceptibility was positively correlated to the baseline pain threshold and the change of pain threshold ( P <0. 01). Conclusion: Pain threshold at hypnotic state was significantly increased. Increasing pain threshold may be regarded as an objective index at hypnotic state.
