Repetitive transcranial magnetic stimulation (rTMS) has been used to treat opioid and methamphetamine addiction in previous studies, while no evidence was proved for patients methadone maintenance therapy with methamphetamine abuse. The aim of this study is to evaluating the effectiveness and safety of rTMS treatment for methamphetamine abuse in patients with methadone maintenance therapy.


First, a multicenter, double-blind, randomized control study is going to be carried out. 100 recruited patients will be randomized assigned to the intervention group and the control group, receiving either 4-week of repetitive transcranial magnetic stimulation (rTMS) treatment or 4-week of sham rTMS treatment. Both groups will receive 16-week urine drug test (1 time per week, 4 weeks before rTMS, 4 weeks during rTMS and 8 weeks after rTMS). Negative rate of urine test for methamphetamine is set as primary outcome. Cognitive function and craving are also evaluated before and after the intervention. Functional magnetic resonance imaging (fMRI) is applied to investigate the potential neurobiological mechanism of rTMS treatment. This study will be very helpful to develop an evidence-based rTMS treatment protocols for methadone maintenance therapy with methamphetamine abuse and decrease risk of relapse for both the patients and their families.
