Summary

The purpose of this study is to determine whether rTMS are effective in the treatment of tinnitus

Detailed description

Repetitive transcranial magnetic stimulation (rTMS) of the dorsolateral prefrontal cortex (DLPFC) has an add-on effect for primary auditory cortex rTMS in improving tinnitus-related distress. We aimed to investigate whether rTMS of the dorsolateral prefrontal cortex and primary auditory cortex are capable of reducing tinnitus loudness. Linked to a neuronavigation system that is guided by magnetic resonance imaging (MRI) of the frontal and temporal, rTMS can suppress areas of cortical plasticity. This cortical reorganization can be demonstrated by magnetoencephalography (MEG)

Conditions

• Tinnitus

Interventions

Type	Name	Description
DEVICE	1	repetitive transcranial magnetic stimulation (Figured 8-Coil MCF-B65): 1000 stimuli of 1Hz rTMS over the left DLPFC (110% motor threshold) followed by 2000 stimuli of 1 Hz rTMS over the left temporal cortex (110% motor threshold), each consisting of 4 days of rTMS treatment. Participants will have an MRI scan and MEG recoding at the performed a week before rTMS. And MEG recording after 7day the application of rTMS
DEVICE	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. Participants will have an MRI scan and MEG recoding at the performed a week before rTMS. And MEG recording after 7day the application of rTMS.
DEVICE	3	repetitive transcranial magnetic stimulation (Figured 8-Coil MCF-B65): 3000 stimuli of 1 Hz rTMS over the left frontal cortex (110% motor threshold) each consisting of 4 days of rTMS treatment. Participants will have an MRI scan and MEG recoding at the performed a week before rTMS. And MEG recording after 7day the application of rTMS.
DEVICE	4	Sham rTMS, applied with the same combination of parameters as active rTMS, except for the number of stimulations per session. Participants will have an MRI scan and MEG recoding at the performed a week before rTMS. And MEG recording after 7day the application of rTMS.
