Repetitive Transcranial Magnetic Stimulation as a Treatment for Tinnitus (rTMS)

October 8, 2018 updated by: Seoul National University Hospital

Verification of the Usefulness of the Repetitive Transcranial Magnetic Stimulation in the Treatment of Chronic Tinnitus

Efficacy of different protocols of transcranial magnetic stimulation for the treatment of tinnitus

Study Overview

Status

Unknown

Conditions

Intervention / Treatment

Detailed Description

Repetitive transcranial magnetic stimulation (rTMS) of the dorsolateral prefrontal cortex has an add-on effect for primary auditory cortex rTMS in improving tinnitus-related distress. The investigators aimed to investigate whether rTMS of the dorsolateral prefrontal cortex and primary auditory cortex are capable of reducing tinnitus loudness.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Active rTMS1
Combined low frequency frontal and temporal repetitive transcranial magnetic stimulation of left primary auditory cortex and left dorsolateral prefrontal cortex
Device: Active rTMS 1
repetitive transcranial magnetic stimulation (Figured 8-Coil Cool-B65): 1000 stimuli of 1Hz rTMS over the left dorsolateral prefrontal cortex (110% motor threshold) followed by 2000 stimuli of 1 Hz rTMS over the left primary auditory cortex (110% motor threshold), each consisting of 4 days of rTMS treatment. (20 subjects).
Active Comparator: Active rTMS2
Temporal low frequency repetitive transcranial magnetic stimulation of left primary auditory cortex
Device: Active rTMS 2
repetitive transcranial magnetic stimulation (Figured 8-Coil MCF-B65): 3000 stimuli of 1 Hz rTMS over the left temporal cortex (110% motor threshold), each consisting of 4 days of rTMS treatment. (20 subjects)
Active Comparator: Active rTMS3
Frontal low frequency repetitive transcranial magnetic stimulation of left dorsolateral prefrontal cortex
Device: Active rTMS 3
repetitive transcranial magnetic stimulation (Figured 8-Coil MCF-B65): 3000 stimuli of 1 Hz rTMS over the left dorsolateral prefrontal cortex (110% motor threshold) each consisting of 4 days of rTMS treatment. (20 subjects)
Sham Comparator: Sham Condition
Combined low frequency frontal and temporal repetitive transcranial magnetic stimulation of left primary auditory cortex and left dorsolateral prefrontal cortex
Device: sham condition
Sham rTMS, applied with the same combination of parameters as active rTMS, except for the number of stimulations per session. (20 subjects)
