Two methods of relaxation therapy, electromyograph biofeedback and autogenic training, were compared to a nonrelaxation treatment, electrosleep therapy, in reducing sleep latency among 22 chronic, sleep-onset insomniacs. While none of the electrosleep patients improved on all-night laboratory electroencephalographic sleep records or daily home sleep logs, approximately one-half of the relaxation-treated patients showed marked improvement, which was sustained over a 1-month follow-up period. Although some sleep and treatment variables differentiated relaxation therapy responders from nonresponders, external stress appeared to be the most salient factor. Successful and unsuccessful patients could not be differentiated on any of the psychological variables studied.
在22名慢性入睡性失眠症患者中，对两种放松疗法（肌电图生物反馈疗法和自生训练法）与一种非放松疗法（电睡眠疗法）进行了比较，以减少睡眠潜伏期。在整夜实验室脑电图睡眠记录或日常家庭睡眠日志方面，接受电睡眠疗法的患者均无改善，而接受放松疗法的患者中约有一半显示出明显改善，且在1个月的随访期内持续存在。尽管一些睡眠和治疗变量区分了放松疗法的应答者和无应答者，但外部压力似乎是最突出的因素。在研究的任何心理变量上，成功和不成功的患者都无法区分。
