About this trial

Tinnitus - the awareness of sound without any outside source - affects around 15% of people and can cause anxiety and depression. Treatment options are limited and do not address tinnitus directly (e.g., reduce its loudness). To do that, we must change brain activity causing tinnitus. Low-dose electrical stimulation, using a technique called transcranial Direct Current Stimulation (tDCS), is a promising approach. The technique is safe and easy to administer. Several small studies have tested tDCS for tinnitus showing some benefits.

To assess whether these benefits will generalise to other patients, we need to conduct a randomised controlled trial - a large, rigorously controlled experiment based on prior agreed procedures. Clinical trials are expensive and time-consuming to run and thus require meticulous pilot work to establish the most effective treatment regimens and the most sensitive measures of treatment outcome. The current study aims to provide such pilot information for a clinical trial of tDCS treatment of tinnitus. Using a total of 40 patients, we will establish how to best to administer tDCS and measure resulting changes in tinnitus perception and associated brain activity.

The current study is a crucial first step towards determining whether or not tDCS can effectively treat tinnitus.

Trial outcomes

Primary outcomes

1

Proof of concept

Measured by protocol compliance and attrition

Time frame
Assessed at study end (anticipated as 1 year after study start)

Secondary outcomes

1

Tinnitus symptom severity

Measured by Tinnitus Functional Index (TFI); maximum score: 100, higher score indicates greater tinnitus symptom severity

Time frame
Before first intervention session, after final intervention session and at 3-month follow-up
2

Tinnitus loudness

Measured by 10-point visual analogue scale, higher score indicates higher tinnitus loudness and by audiometric tinnitus loudness matching, with higher dB indicating higher loudness

Time frame
Before first intervention session, after each intervention session and at 3-month follow-up (VAS). Before first intervention session and after final intervention session (loudness matching)
3

Depression

Measured by Patient Health Questionnaire (PHQ-9) scores can range from 0 to 27 with a higher score indicating more severe symptoms

Time frame
Before first intervention session, after final intervention session and at 3-month follow-up
4

Anxiety

Measured by Generalised Anxiety Disorder Assessment (GAD-7) scored from 0 to 21, with a higher score indicating more severe anxiety

Time frame
Before first intervention session, after final intervention session and at 3-month follow-up
