A double-blind, randomised controlled pilot clinical trial was conducted to assess the potential effectiveness and safety of low-charge electrotherapy (LCE) for patients with schizophrenia. Bitemporal LCE (approximately 2.8 Joules) was administered three times a week. The Positive and Negative Syndrome Scale score was set as the outcome measure. Any adverse event (AE) was recorded. Three visits occurred at baseline, post-treatment, and after one month of follow-up. Twelve patients were randomised to the electroconvulsive therapy (ECT) group or LCE group (6 patients in each group). No patient withdrew during the study. The LCE group did not experience seizures during the trial. Patients in both groups showed significant improvements in clinical measures after treatment, and the reduction of all scale scores between the two groups was nonsignificant. The LCE group experienced significantly fewer AEs than the ECT group. Compared with ECT, LCE exerts similar antipsychotic effects while causing fewer AEs. Thus, LCE has the potential to be a safe and effective treatment for patients with schizophrenia, but further research is needed.
