Headache patients and healthy controls underwent alpha-EEG feedback training in 12 sessions. The present study does not support the literature which reports alpha increase by feedback training. The study included a patient group receiving feedback, a patient control group receiving pseudofeedback, and a volunteer group receiving feedback. Increase of alpha EEG was observed under feedback and pseudofeedback. However, there was always more alpha during baseline times than during training times. Alpha increase over time is suggested to be a habituation effect. Headache pain decreased with training (within the boundaries of a placebo effect), and there was no difference in headache decrease between feedback and pseudofeedback patients.
头痛患者和健康对照者接受了为期12节的α脑电反馈训练。本研究不支持文献中所报道的通过反馈训练使α波增加的观点。该研究包括一个接受反馈的患者组、一个接受伪反馈的患者对照组以及一个接受反馈的志愿者组。在反馈和伪反馈情况下均观察到α脑电的增加。然而，基线期的α波总是比训练期更多。α波随时间增加被认为是一种习惯化效应。头痛疼痛随训练而减轻（在安慰剂效应范围内），反馈组和伪反馈组患者在头痛减轻方面没有差异。
