About this study

Official title: 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.

Read the 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).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Continuous theta burst stimulation (cTBS)Device

    50Hz of 90% MT for 3 pulses train over will be repeated at 200ms for the 40s, 600 pulses

  • shame rTMSDevice

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Symptom improvement assessed by the Yale-Brown Obsessive Compulsive Scale

    The responder on Y-BOCS is defined as a Y-BOCS decrease at least 25% from the baseline at post-treatment

    Measured: Up to 6 months

Secondary outcomes (9)
  1. The Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS)

    The DY-BOCS self-report is composed of an 88-item self-report checklist, designed to provide a detailed description of obsessions and compulsions that are divided into six different OC symptom dimensions.

    Measured: Up to 6 months

  2. The Barratt Impulsiveness Scale-11 (BIS-11)

    It is is an important tool for measuring impulsivity.

    Measured: Up to 6 months

  3. The Beck Depression Inventory(BDI)

    It is a 21-item self-report measure scored on a 4-point Likert-type scale to summarize recent symptoms of depression.

    Measured: Up to 6 months

  4. The Beck Anxiety Inventory (BAI)

    It is a 21-item self-report inventory that is used for measuring the severity of anxiety.

    Measured: Up to 6 months

  5. State-trait Anxiety Inventory(STAI)

    It has 20 items for assessing trait anxiety and 20 for state anxiety.

    Measured: Up to 6 months

  6. Perceived Stress Scale(PSS)

    It is to measure the degree to which situations in one's life are appraised as stressful.

    Measured: Up to 6 months

  7. Pittsburgh sleep quality index(PSQI)

    It is a self-report questionnaire that assesses sleep quality over a 1-month time interval.

    Measured: Up to 6 months

  8. The Obsessive-Compulsive Inventory-Revised(OCI-R)

    It's a self-report designed to measure the principal dimensions which characterise obsessive-compulsive disorder.

    Measured: Up to 6 months

  9. side effects

    It measures side effects including dizziness, headache, itching and so on.

    Measured: Up to 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Continuous theta burst stimulation (cTBS) in people with Obsessive-Compulsive Disorder, run by Shanghai Mental Health Center at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Symptom improvement assessed by the Yale-Brown Obsessive Compulsive Scale (time frame: Up to 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 May 2025; AzTrials last refreshed its copy on 8 Nov 2026.
