This study tested whether osteopathic manual therapy—gentle hands-on techniques for muscles and joints—can reduce the discomfort and loudness of tinnitus in people whose symptoms change with movement. Fifty-four adults with tinnitus for at least six months received either real os…

This study tested whether playing specific sounds can temporarily reduce the loudness of tinnitus (ringing in the ears). Forty-five adults with chronic tinnitus listened to personalized sound clips for 3 minutes and 20 minutes. Researchers measured how much the tinnitus quieted d…

This pilot study tested a non-invasive white noise device called TinniSoothe in 20 UK veterans with persistent tinnitus. Participants wore the device around their neck during the day and docked it at night for at least one month. The goal was to see if it reduces tinnitus symptom…

This early study tested a new implant device for people with severe tinnitus (ringing in the ears). Nine adults received the implant to see if it was safe and could reduce their symptoms. The study measured side effects and used questionnaires to track changes in tinnitus severit…

This completed study tested whether manual therapy (hands-on treatment) on the neck can reduce tinnitus in people whose ringing ears are linked to neck pain. 31 adults with somatic tinnitus received either manual therapy or neck exercises. The goal was to see if treating the neck…

This study tested whether injections of incobotulinum toxin A (similar to Botox) into muscles around the ear can relieve tinnitus, a persistent ringing in the ears. Forty-one adults with tinnitus for at least two months received either the drug or a placebo injection. The main go…

This study tested whether combining mild electrical brain stimulation (tRNS) with white noise can temporarily reduce tinnitus symptoms. 35 adults with chronic tinnitus received either the combined treatment or brain stimulation alone. Researchers measured changes in tinnitus loud…

This study tested an herbal compound in 108 adults who had trouble sleeping and tinnitus (ringing in the ears) but did not want to take sleeping pills. Participants took either a low dose, high dose, or placebo daily for 3 months. Researchers measured changes in sleep quality and…

This study tested whether people with tinnitus can tell if they are receiving real or fake ultrasound stimulation of the vagus nerve in the ear. Twenty adults with constant tinnitus for at least six months took part. The goal was to see how well the blinding worked and what side …

This study tested whether a smartphone app could provide the same relief for chronic tinnitus as face-to-face counseling. 42 adults with constant ringing in their ears received either app-based or in-person counseling over six weeks. The goal was to see if the app could reduce th…
