Home-based Transcranial Electrical Stimulation (TES) in Patients With Chronic Tinnitus

A Preliminary Clinical Trial for Efficacy of Non-invasive Home-based Transcranial Electrical Stimulation (TES) Therapy in Patients With Intractable Chronic Tinnitus

The investigators applied home-based transcranial electrical stimulation (TES) for neuromodulative treatment in patients with intractable chronic tinnitus.

For treatment of motor and psychiatric disorders, transcranial electrical stimulation including transcranial direct current stimulation (tDCS), transcranial magnetic stimulation (TMS), or transcranial random noise stimulation (tRNS) are in use worldwidely. The investigators applied these neuromodulation techniques into patients with intractable chronic tinnitus for symptom relief. Experimental groups with 60 subjective tinnitus subjects will be consisted of three different treatment groups which are: TES group, TES with sham stimulation group, and control group. Subjects will be given 1.0 milliampere (mA) TES on bifrontal areas for neuromodulation.

Inclusion Criteria:

• Research volunteers with intractable chronic tinnitus who agreed to participate in the clinical trial were gathered from the tinnitus clinic of the Department of Otorhinolaryngology Head-and-Neck Surgery, Seoul National University Bundang Hospital

Exclusion Criteria:

• psychoactive drug user
• implanted material
• pacemaker user
