NCT04264741

Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Self-report drug use and urine test

    Patients will be asked to report their drug use for 16 weeks every day and do urine tests once a week for 16 weeks. Loss of visit or rejecting to report or rejecting to do urine tests will be treated as drug use positive (relapse).

    16 weeks

Secondary Outcomes (3)

  • Change of Craving assessed by Visual Analog Scale

    12 weeks

  • Cognitive function assessed by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS)

    12 weeks

  • Functional magnetic resonance imaging

    4 weeks

Study Arms (2)

rTMS treatment group

EXPERIMENTAL

For rTMS treatment, we will stimulate the dorsal lateral prefrontal cortex of each patients using the iTBS pattern everyday. Treatment will lasted for 4 weeks.

Device: repetitive transcranial magnetic stimulation (rTMS)

sham rTMS treatment group

SHAM COMPARATOR

For sham rTMS treatment, we will stimulate the dorsal lateral prefrontal cortex of each patients using the sham iTBS pattern and sham coil everyday. Treatment will lasted for 4 weeks.

Device: sham repetitive transcranial magnetic stimulation (rTMS)

Interventions

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.
