Effect of repetitive transcranial magnetic stimulation combined with cognitive behavioral therapy on insomnia in menopausal women / 中华行为医学与脑科学杂志

ABSTRACT

Objective:To explore the effect of repetitive transcranial magnetic stimulation(rTMS) combined with cognitive behavioral therapy for insomnia(CBT-I)for menopausal women with insomnia.Methods:A total of 76 menopausal women with insomnia who were hospitalized from April 2020 to October 2021 were enrolled.Then they were randomly divided into observation group and control group, with 38 cases in each group.Both observation group and control group were treated with CBT-I. Meanwhile, the patients in observation group were treated with low-frequency repetitive rTMS, on the contrary, the patients in control group were treated with sham rTMS.The intervention lasted for 4 weeks.Insomnia severity index (ISI), Pittsburgh sleep quality index (PSQI) and polysomnography (PSG) were all recorded at baseline and 4 weeks after intervention, as well as adverse events. Data was analyzed by SPSS 22.0 software. Data which was normally distributed, was compared by independent t-test and paired t-test. Results:(1)The scores of ISI (16.39±4.03, 15.66±4.89) and the PSQI(14.97±2.70, 14.11±3.60) in observation group and control group at baseline were not significantly different( t=-0.716, -1.190, both P>0.05). After treatment, the ISI and PSQI scores of the observation group (10.08±3.65, 9.58±1.73)were lower than those of the control group (12.82±4.47, 12.13±2.32), and the differences were statistically significant ( t=2.926, 5.440, both P<0.05). (2) After treatment, all sleep parameters were significantly improved from baseline in observation group (all P<0.05). Sleep efficiency, wake time during sleep, and number of awakenings were significantly improved from baseline in control group(all P<0.05). Compared with control group((70.38±12.99)%, (17.39±11.75)%, (13.98±6.35)%), the observation group reported a greater statistically improvement in sleep efficiency, N3% and REM%((79.52±9.31)%, (22.80±6.05)%, (18.78±6.68)%, respectively)( t=-3.526, -2.524, -3.212, all P<0.05). Neither group had serious adverse effects. Conclusion:The rTMS combined with CBT-I can significantly improve the sleep quality in menopausal women with insomnia. With its high safety rTMS combined with CBT-I may be a recommended non-drug therapy among menopausal women with insomnia.
