Repetitive Transcranial Magnetic Stimulation (rTMS) in the Treatment of Obsessive Compulsive Disorder
September 7, 2022 updated by: Zhen Wang, Shanghai Mental Health Center
A Randomized Clinical Trial of Repetitive Transcranial Magnetic Stimulation (rTMS) Treatment for Obsessive-Compulsive Disorder
This study will evaluate the possible therapeutic effects of repetitive transcranial magnetic stimulation(rTMS) in obsessive-compulsive disorder (OCD) in OCD patients who have not fully responded to pharmacotherapy, and the underlying neural mechanism by EEG.

Detailed Description
The purpose of study is to examine the efficacy of rTMS over different brain areas, including the bilateral supplement motor Area (SMA), the right dorsal lateral prefrontal cortex (DLPFC) and SMA+DLPFC in the treatment of OCD. 120 OCD patients will be randomized into four groups.
Continuous theta burst stimulation (cTBS) stimulation will be performed once a day, five times a week, for four weeks.
The investigators will assess improvement after four weeks of cTBS.
Though the study, Yale-Brown Obsessive Compulsive Scale(Y-BOCS), the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS), the Barratt Impulsiveness Scale-11 (BIS-11), the Beck Depression Inventory(BDI), the Beck Anxiety Inventory (BAI), Perceived Stress Scale(PSS), Pittsburgh sleep quality index(PSQI), the Obsessive-Compulsive Inventory-Revised(OCI-R) and side effects will be obtained by a trained investigator.
The patients will also receive magnetic resonance imaging scan and electroencephalography (EEG).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Group1: rTMS(bilateral SMA)
Continuous theta burst stimulation (cTBS) stimulation will be applied over the bilateral SMA once a day, 5 days/week, for 4 weeks.
|
50Hz of 90% MT for 3 pulses train over will be repeated at 200ms for the 40s, 600 pulses
|
Experimental: Group2: rTMS(right DLPFC)
Continuous theta burst stimulation (cTBS) stimulation will be applied over the right DLPFC once a day, 5 days/week, for 4 weeks.
|
50Hz of 90% MT for 3 pulses train over will be repeated at 200ms for the 40s, 600 pulses
|
Experimental: Group3: rTMS(right DLPFC+bilateral SMA)
Continuous theta burst stimulation (cTBS) stimulation will be applied over the right DLPFC and bilateral SMA once a day, 5 days/week, for 4 weeks.
|
50Hz of 90% MT for 3 pulses train over will be repeated at 200ms for the 40s, 600 pulses
|
Sham Comparator: Group4: shame rTMS
The sham rTMS will be applied over the bilateral SMA once a day, 5 days/week, for 4 weeks.
|
The sham coil has been specifically developed to mimic the real one but is not associated with a stimulus sensation compared to the coil delivering real stimulation cTBS.
