Brief Summary:
This study aimed at verifying whether sessions of repetitive transcranial magnetic stimulation over a certain brain area (the supplementary motor area) could be useful in the relief of Obsessive-Compulsive Disorder symptoms.

Condition or disease Intervention/treatment Phase
Obsessive Compulsive Disorder Device: Repetitive Transcranial Magnetic Stimulation (rTMS) Device: Sham repetitive transcranial magnetic stimulation Phase 2

Detailed Description:
Patients were randomly administered either real (n = 12) or sham (n = 10) rTMS, once a day, 5 days a week, for 2 weeks. Randomization was performed according to a computer-generated schedule. Subjects and scale-rater physician were blind to treatment status of individuals. Only the rTMS administrator was aware of group allocations. Treatment response was assessed by self-and clinician-rated scales before treatment, immediately after treatment and 3 months thereafter, with the same examiner following a subject throughout the study. All patients included in the study had failed adequate pharmacological treatment for at least 2 antiobsessional drugs. Their prescription drugs were continued without change in dosage regimens throughout the study.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 22 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Randomized Double-blind Trial of Repetitive Transcranial Magnetic Stimulation in Obsessive -Compulsive Disorder With Three Months Follow-up
Study Start Date : May 2011
Actual Primary Completion Date : September 2011

Arm Intervention/treatment
Active Comparator: Transcranial Magnetic Stimulation
Actual transcranial magnetic stimulation of supplementary motor areas bilaterally.
Device: Repetitive Transcranial Magnetic Stimulation (rTMS)
rTMS was administered by means of a NEURO-MS (NEUROSOFT LTD®, Russia) with a focal 8-shaped 70 mm coil. Stimulation parameters were 1-Hz, 20-min trains (1200 pulses/day) at 100% of resting MT, once a day, 5 days a week, for 2 weeks.
Other Name: Neuro-MS Transcranial Magnetic Stimulator

Sham Comparator: Sham Transcranial Magnetic Stimulation
Sham transcranial magnetic stimulation over the supplementary motor areas.
Device: Sham repetitive transcranial magnetic stimulation
The sham treatment was performed using the Neurosoft ® sham coil. A metal plate placed inside this coil prevents the magnetic field from stimulating the cortex. This coil looks and sounds like an active coil.
Other Name: Neurosoft sham coil

Primary Outcome Measures :
  1. Changes in Y-BOCS scale scores relative to baseline [ Time Frame: assessments were at baseline, at 2 weeks and at 3 months ]
    Y-BOCS: Yale-Brown Obsessive-Compulsive Scale
