Details and patient eligibility

About

Objective: To understand the personal experience of schizophrenia patients following repetitive transcranial magnetic stimulation (rTMS) and its connection with changes in mental symptoms, thereby enhancing the overall understanding of TMS.

Method: The investigators selected eligible schizophrenia patients for fixed-parameter rTMS treatment. A self-experience checklist post-TMS treatment and positive and negative symptom scales (PANSS) were applied to evaluate the treatment.

Full description

The investigators recruited male subjects admitted to who met the criteria. They were divided into a control and a treatment group. A double-blind approach was adopted. The subjects were unaware of whether real/pseudo stimulation was applied, and the evaluators did not know the grouping specifics. All of the enrolled cases were tested for stimulation thresholds in the bilateral prefrontal cortex. The TMS treatment device was a Magstim RAPID2 neuromagnetic stimulator (Magstim) with an "8"-type coil. The study group was administered real stimulation. The treatment parameters were as follows: frequency range, 20 Hz; 90% motion threshold; 3 s of stimulation; a 57 s interval; 15 min of stimulation for each side, five times per week for a total of 20 times. For the control group, a 60% motion threshold was set; the remaining parameters were consistent with the study group but with no stimulating energy output. The therapeutic instrument model, appearance, operation process, and sounds when effecting treatment were the same for both groups. A self-experience checklist post-TMS treatment and positive and negative symptom scales (PANSS) were applied to evaluate the treatment.
