The Efficacy of Combined Electroacupuncture and Auricular Pressure on Sleep Quality in Patients Receiving Methadone Maintenance Treatment.

Abstract

Previous studies have revealed that the electroacupuncture or auricular-point pressure as a single treatment approach is beneficial for relieving insomniac symptoms among patients under methadone maintenance treatment (MMT). This study is designed to evaluate the clinical efficacy of combining two treatments. This study was a randomized, controlled, crossover trial. A total of 50 participants were recruited from the Linsen Chinese Medicine and Kunming Branches of Taipei City Hospital and randomly assigned to Groups A (25 participants) and B (25 participants). In Group A (electroacupuncture at the Hegu point (LI4) and Zusanli point (ST36) and auricular-point pressure on the Shenmen point) and Group B (only auricular-point), the interventions were implemented biweekly for 4 weeks. After a 1-week washout period, a crossover of the groups was performed. Sleep quality, according to the Pittsburgh Sleep Quality Index (PSQI), and daily attendance rate of MMT were evaluated. Combined therapy significantly improved sleep quality, especially in the PSQI subscales of subjective sleep quality (60.91% vs 20.93%, P < 0.05) and sleep latency (42.59% vs 11.28%, P < 0.05). A significantly higher daily attendance rate was noted in combined therapy than single therapy (87% ± 2% vs 82% ± 2%, P < 0.001). The combination of the electroacupuncture with auricular-point pressure demonstrated high efficacy for improving sleep quality and increasing MMT adherence compared with single therapy of auricular-point pressure. Combined therapy of the electroacupuncture and auricular-point pressing should be introduced as a routine, facilitating treatment for patients under methadone maintenance. (Am J Addict 2020;00:00-00).
