A Chinese study suggests that acupuncture compares favourably with benzodiazepine drugs for improving sleep quality and daytime functioning in insomnia patients. A total of 180 patients with primary insomnia were randomly assigned to one of three groups. The verum group received verum acupuncture and a placebo drug; the estazolam group received the drug estazolam and sham acupuncture; and the sham group received sham acupuncture and a placebo drug. All three groups showed significant improvement in sleep quality scores compared with pretreatment baseline. Compared with the other two groups, the verum group reported significantly improved sleep quality and vitality, along with decreased daytime dysfunction and sleepiness.
