催眠已被证明在一系列临床条件下有效，包括慢性疼痛的管理。然而，并不是所有的人都能进入催眠状态，从而限制了这种技术的临床应用。我们试图确定是否可以使用三种被认为有助于放松的方法来增加催眠的敏感性，特别是对EEG神经反馈协议的兴趣，该协议提高了θ与α的比率。这与渐进式肌肉放松和自我催眠进行了比较。10名具有中等敏感性水平的受试者（2-7/12）被随机分配到每种条件下，并在10次训练之前和完成时评估催眠敏感性。催眠易感性增加后的培训在所有群体中，提供了进一步的证据，操作性控制的θ/α比是可能的，但与我们的预测相反，海拔θ/α比证明没有更成功的比其他干预措施。尽管如此，所有三种技术都成功地增强了一半以上参与者（17/30）的催眠易感性，与使用其他方法报告的发生率相似。如前所述，大多数对修饰不敏感的人处于较低的敏感性水平，并且更大的增加往往发生在更敏感的受试者中。然而，在这里，在一些低水平的增强被公开，并发现达到高水平的能力，这两个功能通常没有报告。进一步的研究是必要的。(c)2006爱思唯尔公司All rights reserved.
Hypnosis has been shown to be efficacious in a range of clinical conditions, including the management of chronic pain. However, not all individuals are able to enter a hypnotic state, thereby limiting the clinical utility of this technique. We sought to determine whether hypnotic susceptibility could be increased using three methods thought to facilitate relaxation, with particular interest in an EEG neurofeedback protocol which elevated the theta to alpha ratio. This was compared with progressive muscle relaxation and self-hypnosis. Ten subjects with moderate levels of susceptibility (2-7/12) were randomly assigned to each condition and assessed for hypnotic susceptibility prior to and upon completion of 10 sessions of training. Hypnotic susceptibility increased post-training in all groups, providing further evidence that operant control over the theta/alpha ratio is possible, but contrary to our predictions, elevation of the theta/alpha ratio proved no more successful than the other interventions. Nonetheless, all three techniques successfully enhanced hypnotic susceptibility in over half of the participants (17/30), a similar incidence to that reported using other methods. As previously reported, the majority who were not susceptible to modification were at the lower levels of susceptibility, and the greater increases tended to occur in the more susceptible subjects. However, here enhancement was disclosed in some at low levels, and capability was found of reaching high levels, both features not typically reported. Further research is warranted.
