Outcome Measures

Primary Outcomes (1)

  • Symptom improvement assessed by the Yale-Brown Obsessive Compulsive Scale

    The Yale-Brown Obsessive Compulsive Scale is a test to rate the severity of obsessive-compulsive disorder symptoms, which measures obsessions separately from compulsions. The scale includes 10 items, the first 5 items are evaluated obsessions, the rest are assessments compulsions. Each item 0-4 points, a total of 40 points. The lower the score, the better the outcome.

    up to 1 months

Secondary Outcomes (5)

  • Stop-Signal Task

    pre-treatment; 1 day post-treatment

  • Task Switch

    pre-treatment; 1 day post-treatment

  • Wisconsin CardSorting Test

    pre-treatment; 1 day post-treatment

  • Hanoi Tower

    pre-treatment; 1 day post-treatment

  • Symptom improvement assessed by the Padua Inventory-Washington State University Revision

    up to 1 months

Study Arms (2)

Real Stimulation

ACTIVE COMPARATOR

The repetition transcranial magnetic stimulation(rTMS) lasted 30 mins and delivered at 1 Hz with 1s duration, a total of 1800 pulses at 110% of the rest motor threshold (RMT) . MRI dataset should be acquired before the first rTMS session and after the last rTMS session.

Device: transcranial magnetic stimulation with real coil

Sham Stimulation

SHAM COMPARATOR

The procedure of this protocol was performed by a placebo coil, lasted 30 mins and delivered at 1 Hz with 1s duration, a total of 1800 pulses at 110% of the rest motor threshold (RMT). No actual magnetic stimulation was applied on the head of the volunteers. MRI dataset should be acquired before the first rTMS session and after the last rTMS session.

Device: transcranial magnetic stimulation with sham coil

Interventions

TMS with real coil is a noninvasive technique to activate and modify the activity of the neurons

Real Stimulation

TMS with sham coil is a placebo

Sham Stimulation
