Low-dose transcranial direct current stimulation (tDCS) for tinnitus

Transcranial Direct Current Stimulation (tDCS) for Tinnitus - Effects of Multiple Treatment Sessions: a Randomised-controlled Pilot Study

NA · University of Nottingham · NCT06628414

This study will test whether low-dose transcranial direct current stimulation (tDCS) can reduce how loud or distressing tinnitus is for adults with subjective tinnitus.

What this trial studies

This pilot study will apply low-dose tDCS to adults with subjective idiopathic tinnitus to identify the most effective stimulation regimens and the most sensitive outcome measures for future trials. Eligible participants who can safely undergo tDCS and provide informed consent in English will receive controlled stimulation sessions following predefined procedures, with randomisation and blinding used where feasible. The primary focus is on safety, tolerability, and detecting a signal of clinical benefit rather than providing definitive proof of efficacy. The work is conducted at the University of Nottingham and is intended to guide a larger, definitive randomised trial.

Who should consider this trial

Good fit: Adults aged 18 or over with subjective idiopathic tinnitus who can consent in English and are medically eligible for tDCS are the ideal candidates.

Not a fit: People with objective tinnitus, those under 18, individuals unable to safely undergo tDCS, or those who cannot provide informed consent in English are unlikely to benefit or be eligible for this study.

Why it matters

Potential benefit: If successful, this approach could reduce tinnitus loudness or distress and improve daily functioning for some patients.

How similar studies have performed: Several small previous studies of tDCS for tinnitus have reported some benefit, but the evidence is limited and inconsistent, so larger pilot work is needed.
