Randomized single-blind multicenter trial comparing the effects of standard and augmented acupuncture protocols on sleep quality and depressive symptoms in patients with depression.

The study was aimed to compare the effects of standard and augmented acupuncture on depressive symptoms and sleep disturbances in patients with depression. This is a randomized, single-blind, multicenter trial. 140 subjects with clinical insomnia (score of ≥ 7 on the Pittsburgh Sleep Quality Index (PSQI)) were randomized to the standard (LI4, LIV3, EX-HN3, and GV20) or augmented (LI4, LIV3, EX-HN3, GV20, LU7, and KID6, including intradermal needles for sustained treatment) acupuncture groups. Participants received two sessions weekly for six weeks. In trial, The primary outcomes were improvements in PSQI and the Hamilton Rating Scale (HAMD). Secondary outcomes were treatment credibility and adverse events. Outcomes were assessed at baseline, week 3, end of treatment, and 4-week follow-up. From the 105 randomized patients, 89 completed the trial and were included in the final analyses. Better efficacy was observed in the augmented group compared with the standard acupuncture to improve the PSQI and HAMD at week 3, end of treatment, and 4-week follow-up (all p < .05). The HAMD scores improved with time, except between end of treatment and 4-week follow-up, while in the standard group, HAMD scored improved from baseline to week 3, and stopped improving thereafter. The PSQI scores improved with time in the two groups, except between end of treatment and 4-week follow-up. Compared with the standard protocol, the augmented acupuncture protocol had a better efficacy to treat depression and to improve sleep quality of patients with depression.
