Trial Outcomes & Findings for Transcranial Magnetic Stimulation Effects on Nicotine Craving (NCT NCT01690130)

NCT ID: NCT01690130

Last Updated: 2020-04-01

Results Overview

Seventy highly palatable scenic images, forty neutral control images) and forty cigarette smoking cue images were presented in four blocks. Immediately after viewing each block of cue images, participants completed a 10 question computerized visual analog scale (CVAS) designed to assess craving. Each question is followed by a CVAS (range 0 - 100) 0 means least amount of craving and 100 means the maximum amount of craving. After 15 minutes of real or sham rTMS, participants viewed the images again and rated their cravings. At each visit, participants were blind to the rTMS condition (real or sham) and the order was randomized.

Measure
Transcranial Magnetic Stimulation, Then Sham
Transcranial magnetic stimulation (TMS) is a noninvasive (and relatively painless) brain stimulation technology that can focally stimulate the brain of an awake individual.The brain stimulation techniques could theoretically improve the efficacy of smoking cessation. Treatment was standardized at 100% magnetic field intensity relative to the participant's resting MT, at 10 pulses per second (10 Hz) for 5 seconds, with an intertrain interval of 10 seconds. Treatment session lasted for 15 minutes with 3000 pulses. Transcranial Magnetic Stimulation (Neuronetics): Transcranial magnetic stimulation is a noninvasive brain stimulation that can focally stimulate the brain of an awake individual. A TMS pulse focally stimulates the cortex by depolarizing superficial neurons which induces electrical currents in the brain.
Sham Transcranial Magnetic Stimulation, Then TMS
Sham-TMS procedures: After rMT determination and DLPFC cortex localization, participants were fitted with two electrodes on the scalp just below the hairline. Electrodes were connected to an Epix VT® Transcutaneous Electrical Nerve Stimulation Device (Empi; St. Paul, MN, USA) Transcranial Magnetic Stimulation (Neuronetics): Transcranial magnetic stimulation is a noninvasive brain stimulation that can focally stimulate the brain of an awake individual. A TMS pulse focally stimulates the cortex by depolarizing superficial neurons which induces electrical currents in the brain. Sham Transcranial Magnetic Stimulation: The electrical current of the sham system is titrated to a level matching participants' ratings of active TMS.The sham-TMS scalp discomfort will be matched to that of active TMS.
