Tinnitus retraining therapy Tinnitus retraining therapy Tinnitus retraining therapy (TRT) is a form of habituation therapy designed to help people who suffer from tinnitus, a ringing, buzzing, hissing, or other sound in the ears when no external sound is present. Two key components of TRT directly follow from the neurophysiological model of tinnitus. One of these principles includes directive counseling aimed at reclassification of tinnitus to a category of neutral signals, while the other includes sound therapy which is aimed at weakening tinnitus related neuronal activity. The goal of TRT is management of tinnitus; there is no evidence that TRT can attenuate or
Tinnitus retraining therapy with tinnitus have a comorbid psychological injury or illness (e.g., post-traumatic stress disorder, depression, anxiety, obsessive compulsive disorder, stress, dysfunction of the temporomandibular joint, etc.) that can exacerbate the tinnitus. It has been proposed that tinnitus is caused by mechanisms that generate abnormal neural activity, specifically one mechanism called discordant damage (dysfunction) of outer and inner hair cells of the cochlea. The psychological basis for TRT stems from the fact that the brain exhibits a high level of plasticity. In turn, this allows it to adjust to any sensory signals as long as they do not lead to negative effects.
