Efficacy Analysis of Transcutaneous Auricular Vagus Nerve Stimulation Combined With Tailor-Made Notched Music Therapy in the Treatment of Chronic Subjective Tinnitus

28 de agosto de 2026 actualizado por: Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University

Efficacy Analysis of Transcutaneous Auricular Vagus Nerve Stimulation Combined With Tailor-Made Notched Music Therapy in the Treatment of Chronic Subjective Tinnitus: A Multicenter, Randomized, Double-Blind Controlled Clinical Trial

The goal of this multicenter, randomized, double-blind clinical trial is to compare two treatments for adults with chronic subjective tinnitus. Researchers will determine whether transcutaneous auricular vagus nerve stimulation (taVNS) plus Tailor-Made Notched Music therapy (TMNMT) provides greater relief than the same music therapy combined with sham taVNS.

A total of 444 participants aged 18 to 70 years will be enrolled at multiple study centers. Participants will be randomly assigned in a 1:1 ratio to receive taVNS plus TMNMT or sham taVNS plus the same TMNMT. The treatment period will last 3 months.

Experimental: taVNS + TMNMT Group
Participants receive active transcutaneous auricular vagus nerve stimulation (taVNS) combined with Tailor-Made Notched Music therapy (TMNMT) for 3 months. taVNS is administered at 0.1 Hz, with a pulse width of 250-1000 ms and an intensity of 0-0.5 mA.

Comparador falso: Sham taVNS + TMNMT Group
Participants receive sham transcutaneous auricular vagus nerve stimulation (taVNS) combined with the same Tailor-Made Notched Music therapy (TMNMT) as the experimental arm for 3 months. The initial sham stimulation parameters are 0.1 Hz, a pulse width of 250-1000 ms, and an intensity of 0-0.5 mA.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Effective Rate of Tinnitus Improvement at 3 Months
Periodo de tiempo: Baseline and 3 months after treatment initiation
Treatment response was defined as a reduction of ≥7 points in the THI score from baseline after 3 months of treatment (based on the internationally recognized minimal clinically important difference threshold). Effective rate (%) = (Number of responders / Total number of patients in the corresponding group) x 100%.
Baseline and 3 months after treatment initiation

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Effective Rate of Tinnitus Improvement at 6 and 12 Months
Periodo de tiempo: Baseline, 6 months, and 12 months after treatment initiation
Treatment response was defined as a reduction of ≥7 points in the THI score from baseline after 6 and 12 months of treatment (based on the internationally recognized minimal clinically important difference threshold). Effective rate (%) = (Number of responders / Total number of patients in the corresponding group) x 100%.
Baseline, 6 months, and 12 months after treatment initiation
Change in Visual Analog Scale (VAS) Score for Tinnitus Loudness
Periodo de tiempo: Baseline, 3 months, 6 months, and 12 months after treatment initiation
Change in tinnitus loudness assessed using a 10-point Visual Analog Scale (VAS), ranging from 0 (barely perceptible) to 10 (unbearably loud). The change score (ΔVAS) is calculated as the difference between post-treatment/follow-up scores and baseline. Higher scores indicate greater perceived loudness; a decrease in VAS score indicates improvement in loudness perception.

Change in Acoustic Tinnitus Match Loudness
Periodo de tiempo: Baseline, 3 months, 6 months, and 12 months after treatment initiation
Change in acoustic tinnitus match loudness assessed using a calibrated audiometer in a standard sound-proof environment. The change in loudness threshold is calculated relative to baseline. Assessment method: audiologist-assessed.
Baseline, 3 months, 6 months, and 12 months after treatment initiation
Change in Beck Anxiety Inventory (BAI) Score
Periodo de tiempo: Baseline, 3 months, 6 months, and 12 months after treatment initiation
Change in anxiety symptoms assessed using the Beck Anxiety Inventory (BAI), a 21-item self-reported questionnaire measuring the severity of anxiety symptoms over the past week. Higher scores indicate greater anxiety severity. The change score (ΔBAI) is calculated as the difference between post-treatment/follow-up scores and baseline. Assessment method: self-reported.
Baseline, 3 months, 6 months, and 12 months after treatment initiation
Change in Beck Depression Inventory (BDI) Score
Periodo de tiempo: Baseline, 3 months, 6 months, and 12 months after treatment initiation
