Summary

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.

Conditions

  • Methamphetamine Abuse

Interventions

DEVICE

repetitive transcranial magnetic stimulation (rTMS)

The iTBS group received 900 pulses per day: 3-pulse 50-Hz bursts given every 200 ms (at 5 Hz), 2 s on and 8 s off for 5 min, at 100% resting motor threshold (rMT), over the left DLPFC (F3, EEG system) (4 weeks, 20 daily sessions). A figure-8-shaped Cool-B70 stimulation coil from MagPro X100 device (MagVenture, Farum, Denmark) was used for accurately targeted stimulation. Motor threshold was determined over the left motor cortex, by finding the lowest intensity that produced a motor response in the right abductor pollicis brevis muscles (APB), which produced five motor-evoked potentials responses of at least 50 uV in 10 trials.

DEVICE

sham repetitive transcranial magnetic stimulation (rTMS)

The sham iTBS group received sham stimulation over the left DLPFC (F3, EEG system) (4 weeks, 20 daily sessions). A figure-8-shaped sham Cool-B70 stimulation coil from MagPro X100 device (MagVenture, Farum, Denmark) was used for accurately targeted stimulation. Motor threshold was determined over the left motor cortex, by finding the lowest intensity that produced a motor response in the right abductor pollicis brevis muscles (APB), which produced five motor-evoked potentials responses of at least 50 uV in 10 trials.
