Trial Outcomes & Findings for Repetitive Transcranial Magnetic Stimulation to Reduce Tics (NCT NCT01258790)

NCT ID: NCT01258790

Last Updated: 2014-07-01

Results Overview

The tic severity score based on Yale Global Tic Severity Scale ranges from 0 - 50. A person who has no tics would have a score of 0. High score means a person has severe tics.

Measure
Active Repetitive Transcranial Magnetic Stimulation
In the active arm, patients received 8 sessions of active continuous theta burst stimulation (cTBS) over 2 consecutive days. Four 40-second cTBS sessions were given over a 75-minute period (0, 15, 60, 75 minute marks) for each day. We used Magstim 70mm figure-8 TMS coil, placed over SMA, with the coil handle pointing towards the occiput.
Sham Repetitive Transcranial Magnetic Stimulation
In the sham arm, patients received 8 sessions of active continuous theta burst stimulation (cTBS) over 2 consecutive days. Four 40-second cTBS sessions were given over a 75-minute period (0, 15, 60, 75 minute marks) for each day. We used Magstim sham 70mm figure-8 TMS coil, placed over SMA, with the coil handle pointing towards the occiput.
