Clinical effect analysis of pulsed electromagnetic fields on primary insomnia

Abstract

Objective To investigate the therapeutic effect of pulsed electromagnetic fields (PEMFs) on primary insomnia. Methods A total of 120 patients with primary insomnia admitted to the The First Hospital of Hebei Medical University from January to December 2021 were randomly divided into conventional treatment and sham stimulation group (control group) and conventional treatment and PEMFs stimulation group (PEMFs group), with 60 patients in each group. Before and after 2 weeks of treatment, Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the sleep quality, and Insomnia Severity Index (ISI) was used to evaluate the severity of insomnia. Results The total effective rate of PEMFs group was higher than that of control group [81.67% (49/60) vs. 41.67% (25/60); χ2 = 20.306, P = 0.000]. After treatment, the total PSQI score (F = 228.729, P = 0.000), sleep quality (F = 87.291, P = 0.000), time to fall asleep (F = 181.842, P = 0.000), sleep time (F = 143.355, P = 0.000) and ISI score (F = 361.348, P = 0.000) of the 2 groups were significantly lower than those before treatment. PSQI total score (F = 13.297, P = 0.000), sleep quality (F = 7.573, P = 0.007), time to fall asleep (F = 9.776, P = 0.002), sleep time (F = 8.566, P = 0.004), and ISI score (F = 5.350, P = 0.000) in PEMFs group after treatment were significantly lower than those of the control group. Conclusions PEMFs are safe and effective in the treatment of patient with primary insomnia, which can significantly improve the sleep quality, and can be used as a non ⁃ drug treatment for patients with primary insomnia.
