Repetitive Transcranial Magnetic Stimulation (rTMS) for Tinnitus

June 29, 2011 updated by: UMC Utrecht

Effectiveness of Repetitive Transcranial Magnetic Stimulation (rTMS) Treatment in Patients With Chronic Tinnitus

Tinnitus is a phantom auditory perception of meaningless sound, meaning that there is registration of sound in the absence of an external or internal acoustic stimulus. It is a common problem (prevalence 7-19%) which may interfere with the ability to lead a normal life. Unfortunately, it is a very difficult symptom to treat because there are hardly any therapeutic options for the cause of tinnitus. Most therapies focus on alleviating the condition rather than treating the cause. Tinnitus is thought to be generated in the brain, as a result of functional reorganization of auditory neural pathways and tonotopic maps in the central auditory system, following damage to the peripheral auditory system. Repetitive Transcranial magnetic stimulation (rTMS) is a therapy, based on this concept of reorganization in the auditory cortex. It uses a pulsed magnetic field to disrupt the neural circuit and to thereby (temporarily) excite or inhibit certain brain areas, leading to the suppression of tinnitus.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Triple

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: 1
Neuronavigated rTMS will be applied bilaterally to the auditory cortices, which will be identified through a structural MRI scan. Stimulation will be performed with 1 Hz frequency and an intensity of 110% motor threshold for 2000 stimuli (32 minutes) on each side, on five subsequent days.
Other Names:
  • Magstim rapid2
Sham Comparator: 2
The official sham stimulator for the magstim rapid2 will be used. Sham stimulation will follow the same placement protocol and will also last 2x32 minutes on five subsequent days
