After evaluating 165 insomniacs, 48 psychophysiologic insomniacs were randomly assigned to one of the following four groups: electromyographic (EMG) feedback, combined EMG and theta feedback, sensorimotor rhythm (SMR) feedback, and no treatment (control). Sleep evaluations by home logs and in the laboratory were done before and after biofeedback and nine months later. No feedback group showed improved sleep significantly more than did the controls. The amount of feedback learning correlated significantly with sleep improvement for the SMR group but not for the other groups. Initial tension of the insomniacs correlated positively with sleep improvement for the EMG group, but negatively with sleep improvement for the SMR group. Those treated with the biofeedback that seemed appropriate for their specific deficiencies showed significant sleep improvements, while those who received inappropriate feedback did not. Appropriate biofeedback methods may be effective for specific types of insomnia, but these procedures offer no panacea for all poor sleep.
在对165名失眠症患者进行评估后，48名心理生理性失眠症患者被随机分配到以下四组之一：肌电图（EMG）反馈组、EMG与θ波反馈联合组、感觉运动节律（SMR）反馈组和无治疗（对照组）。通过家庭日志和实验室检查在生物反馈前后以及九个月后进行睡眠评估。无反馈组的睡眠改善情况并不比对照组显著。反馈学习量与SMR组的睡眠改善显著相关，但与其他组无关。失眠症患者的初始紧张程度与EMG组的睡眠改善呈正相关，但与SMR组的睡眠改善呈负相关。接受针对其特定缺陷的生物反馈治疗的患者睡眠有显著改善，而接受不适当反馈的患者则没有。适当的生物反馈方法可能对特定类型的失眠有效，但这些方法并不能解决所有睡眠不佳的问题。
