Trial summary

Tinnitus is the perception of sound in the absence of corresponding external sound. Tinnitus affects approximately 10-15 % of the population. The prevalence increases with age and it is estimated that more than 20 % of the older people have tinnitus. Read more about this study

About this study

Official title: Treatment of Tinnitus With Transcranial Magnetic Stimulation

Tinnitus is the perception of sound in the absence of corresponding external sound. Tinnitus affects approximately 10-15 % of the population. The prevalence increases with age and it is estimated that more than 20 % of the older people have tinnitus. Approximately 10-15 % of tinnitus patients have clinically relevant, disabling tinnitus causing for example anxiety, depression and sleep disturbances. The treatment of chronic tinnitus is difficult and most therapies focus on alleviating the condition rather than treating the cause. Pathophysiology of tinnitus still remains incompletely understood. Functional brain imaging data in tinnitus patients and animal models suggest that tinnitus is associated with increased neuronal activity, increased synchronicity, and functional reorganization within the auditory cortex either uni- or bilaterally, but there are also functional alterations in brain areas outside the auditory system. Transcranial magnetic stimulation (TMS) is a neuromodulation technique based on the principle of electromagnetic induction of an electric field in the brain by means of magnetic pulses given to the scalp. TMS is a non-invasive, painless, and safe method for modulation of cortical activity. TMS pulses given at low frequencies (≤ 1 Hz) have been shown to decrease cortical excitability both in experimental settings and humans, which forms the basis for using low frequency rTMS to treat chronic tinnitus patients, in whom hyperactivity of the auditory cortex has been observed in functional brain imaging studies

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • E-fied navigated rTMSDevice

    1 hz on the superior temporal gyrus contralateral/left side with E-field navigated rTMS (Nexstim) targeted at the tonotopic representation area of the main frequency content of tinnitus

  • non-navigated rTMSDevice

    1 hz on the superior temporal gyrus contralateral/left side with non-navigated rTMS according to external landmarks (between T3/T4 and P3/P4 EEG-electrode locations)

  • sham E-field navigated rTMSDevice

  • Navigated rTMSDevice

    1 hz on the left superior temporal gyrus with (MRI) navigated rTMS (Visor)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The change of loudness and pitch of the tinnitus is psychophysically measured, VAS questionnaires, Tinnitus Handicap Inventory, Tinnitus diary

    Measured: Change from baseline and 2-3 days after treatment period

Questions about this trial

What is this clinical trial studying?

A study testing E-fied navigated rTMS, non-navigated rTMS and Navigated rTMS in people with Tinnitus, run by Turku University Hospital at 1 site in Finland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Finland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The change of loudness and pitch of the tinnitus is psychophysically measured, VAS questionnaires, Tinnitus Handicap Inventory, Tinnitus diary (time frame: Change from baseline and 2-3 days after treatment period). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01929837, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Aug 2016.
