Without that, she says, it’s impossible to know how much patients would have improved on their own or with a placebo. Animal research and pilot human studies have shown that bimodal neuromodulation combining sound and electrical somatosensory stimulation (30), including tongue stimulation (3117), can drive, extensive plasticity in the auditory system and improve tinnitus symptoms. The reduction in symptoms is larger than other studies have found for bimodal stimulation, he says, and it’s the first evidence of such long-term effects. The tinnitus treatment device, now branded as Lenire, which was used in the study was developed by Neuromod and consists of wireless bluetooth headphones that deliver a 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 … The electrical stimulation feels a little like pop rocks candy fizzing in your mouth, Lim says. A noninvasive device that delivers sound to the ears and electrical stimulation to the tongue improved tinnitus symptoms in a trial reported in Science Translational Medicine. One potential explanation for the effect is that hearing loss causes the brain to overcompensate for the frequencies it can no longer hear. For many people, tinnitus is a disturbing ringing sound, while for others it’s a buzzing, hissing, chirping or even roaring in the ears. When he inserted a pencil-size rod covered in electrodes directly into the brains of five patients, some of those electrodes landed slightly outside the target zone – a common problem with deep brain stimulation, Lim says.

The results are “quite impressive,” Cederroth says. Hubert Lim, a biomedical engineer at the University of Minnesota, Twin Cities, hit on the role of the tongue in tinnitus by accident. If you suffer from tinnitus, this is a very effective treatment. But for many people, it’s the brain that’s to blame, perceiving sounds that aren’t there. When the team followed up after 12 months, 80% of the participants still had lower tinnitus scores, with average drops of 12.7 and 14.5 points. It’s “really important” work, says Christopher Cederroth, a neurobiologist at the University of Nottingham, University Park, who was not involved with the study. by Gurprit October 16, 2020 Health In the largest clinical trial of its kind, researchers show 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. Credit: Neuromod Devices Limited The device pairs sound with electrical stimulation on the tongue to treat tinnitus. Each participant received … One potential explanation for the effect is that hearing loss causes the brain to overcompensate for the frequencies it can no longer hear. Tinnitus – a constant ringing or buzzing in the ears that affects about 15% of people – is difficult to understand and even harder to treat. The goal of the two together was to distract the brain by heightening its sensitivity, forcing it to suppress the activity that causes tinnitus. A … And cognitive behavioral therapy, a kind of talk therapy that is currently the only clinically validated tinnitus therapy, improves severity scores by about 10 points on average. Around 10-15 percent of the population may have tinnitus. Now, scientists have shown that gently stimulating the tongue – combined with a carefully designed sound program – can reduce symptoms of the disorder for up to one year. studied the effects of bimodal neuromodulation using a device that delivers electrical stimulation to the tongue and sound to the ears. And they saw an average drop of about 14 points on a tinnitus severity score of one to 100, the researchers report today in Science Translational Medicine. 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 … This bimodal approach is based on the postulate that tinnitus is, in some, linked to a dysfunction of the brain, certain neurons activating abnormally and causing the perception of parasitic noise. A few years ago, he experimented with using a technique called deep brain stimulation to restore his patients’ hearing. And cognitive behavioral therapy, a kind of talk therapy that is currently the only clinically validated tinnitus therapy, improves severity scores by about 10 points on average. It’s “really important” work, says Christopher Cederroth, a neurobiologist at the University of Nottingham, University Park, who was not involved with the study. In a 2015 study on guinea pigs, his lab showed that by stimulating the ear or tongue of an animal, along with playing sound to activate the auditory centers of the brain, they were able to change brain activity patterns in a way that might treat tinnitus or other brain disorders. There is no universally effective treatment for tinnitus, phantom perceived sound, or ringing in the ears. Neuromod Devices Limited This device provides stimulating pulses to 32 electrodes on the tip of the tongue. The tinnitus treatment device consisted 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 embedded in a small non-invasive device placed on the tip of the tongue.

Conlon et al. *Correction, 7 October, 4:05 p.m.: An earlier version of this story stated the tongue was the best part, rather than one of the best parts, to shut off tinnitus in guinea pigs. More than 80% of those who complied with the prescribed regimen saw an improvement. And they saw an average drop of about 14 points on a tinnitus severity score of one to 100, the researchers report today in Science Translational Medicine. In the team’s experiment, 326 people with tinnitus sat for up to 1 hour at a time with a small plastic paddle on their tongue. The technique, which combines sound and electrical stimulation of the tongue, could offer hope for the huge numbers of people (thought to be as much as 15 per cent of the global population) who suffer from the condition. 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 … Users will listen to white noise and what sounds like electronic music while a peripheral provides electronic stimulation to the tongue. Each person heard a rapidly changing series of pure tones at different frequencies, against a background noise that sounds “kind of like electronic music,” Lim says. “The brain can only pay attention to so many things,” Lim says. Patient usage, logged by the device, was used to classify patients as compliant or noncompliant. I can’t hear my tinnitus,” Lim recalls. For instance, there might be repeated muscular contractions in the ear, Lim says. The breakthrough device, called Lenire, combines electrical stimulation on the patient’s tongue with a sequence of sounds delivered to a Bluetooth headset. The findings could potentially help millions of people since tinnitus … But for many people, it’s the brain that’s to blame, perceiving sounds that aren’t there.

He and colleagues tested the ears, neck, limbs, and “you know … other places,” he says, eventually concluding the tongue was the best target. With certain kinds of tinnitus, people hear real sounds. Your email address will not be published. Over the 12 weeks of treatment, the patients’ tinnitus symptoms improved dramatically. The tonguetip is provided for tongue stimulation to investigate the therapeutic effects of bimodal stimulation compared to acoustic-only stimulation and to provide participants with a stimulation setting that is expected to improve tinnitus during the 12-week treatment period based on findings from TENT-A1. Each person heard a rapidly changing series of pure tones at different frequencies, against a background noise that sounds “kind of like electronic music,” Lim says. Still, University of Oxford neuroscientist Victoria Bajo notes there was no control group in the trial. Over the 12 weeks of treatment, the patients’ tinnitus symptoms improved dramatically. Research has shown that it can reduce the symptoms associated with tinnitus by up to 50%. It further said that the sound and electrical stimulation of the tongue resulted in therapeutic effects on tinnitus patients, and soothed the symptoms over a prolonged period of time. A few years ago, he experimented with using a technique called deep brain stimulation to restore his patients’ hearing. In the team’s experiment, 326 people with tinnitus sat for up to 1 hour at a time with a small plastic paddle on their tongue. and somatosensory stimulation was delivered via electrical stimulation of the tongue. A 2018 paper that stimulated the skin on the neck and cheek over a shorter time improved patients’ tinnitus, but there was a smaller dip in severity scores, he notes, of only about seven points. Tinnitus—a constant ringing or buzzing in the ears that affects about 15% of people—is difficult to understand and even harder to treat. Further testing in guinea pigs revealed the best body parts to stimulate to shut off tinnitus, Lim says.
