Are Your Ears Ringing From Tinnitus? This Non-Invasive Nerve Stimulation Could Help Millions

In the largest clinical trial of its kind, researchers have shown that combining sound and electrical stimulation of the tongue can significantly reduce tinnitus, commonly described as “ringing in the ears.” They also found that therapeutic effects can be sustained for up to 12 months post-treatment.

The findings could potentially help millions of people since tinnitus affects about 10 to 15 percent of the population worldwide.

The research was recently published as the cover story of the top peer-reviewed journal Science Translational Medicine.

 

 

The study represents the largest and longest followed-up clinical trial ever conducted in the tinnitus field for a medical device with 326 enrolled participants, providing evidence regarding the safety, efficacy, and patient tolerability of bimodal neuromodulation for the treatment of tinnitus.

 

About 86 percent of treatment compliant participants reported an improvement in tinnitus symptom severity when evaluated after 12 weeks of treatment, with many experiencing sustained benefit 12 months post-treatment.

“I am truly proud of our company’s ability to perform such a large-scale randomized clinical trial in two countries,” University of Minnesota Associate Professor Hubert Lim said. “This study tracked the post-treatment therapeutic effects for 12 months, which is a first for the tinnitus field in evaluating the long-term outcomes of a medical device approach. The outcomes are very exciting and I look forward to continuing our work to develop a bimodal neuromodulation treatment to help as many tinnitus sufferers as possible.”

Thought the study, which was sponsored by Neuromod Devices, there were were consistent therapeutic outcomes across both clinical sites, with no serious adverse events.

The tinnitus treatment device used in the study, now branded as Lenire®, was developed by Neuromod Devices and consists of wireless (Bluetooth®) headphones that deliver sequences of audio tones layered with wideband noise to both ears, combined with electrical stimulation pulses delivered to 32 electrodes on the tip of the tongue by a proprietary device trademarked as Tonguetip®.
