effective treatments for dizziness after bppv: a clinical study

Conditions: BPPV; Residual Disease; Vestibular Disease

Summary: this clinical study aimed to evaluate how effective vestibular rehabilitation therapy (vrt) and theta binaural beats (t-bb) are in reducing dizziness and anxiety in patients who continue to feel unsteady after successful treatment for a common inner ear condition called bppv. a total of 56 adult patients were divided into three groups, each receiving different types of home-based exercises: cawthorne-cooksey exercises (cce), brandt-daroff exercises (bde), or cce combined with t-bb. the study measured both physical balance and emotional symptoms such as anxiety. results showed that all treatments helped, but patients who received cce with t-bb showed the most improvement in both balance and anxiety levels. the findings suggest that combining physical and audio-based therapy may be especially helpful for people with ongoing dizziness after bppv.

residual dizziness (rd) is a common yet often overlooked condition that can persist after successful canalith repositioning procedures (crp) for benign paroxysmal positional vertigo (bppv). despite the resolution of vertigo, many patients continue to report imbalance and anxiety, which may affect their quality of life. this study investigated whether vestibular rehabilitation therapies-specifically cawthorne-cooksey exercises (cce), brandt-daroff exercises (bde), and cce combined with theta binaural beats (cce+t-bb)-could improve balance and reduce anxiety in patients experiencing rd. fifty-six adults aged 18-60 who reported dizziness for at least 20 days after crp were enrolled. participants were assigned to one of the three intervention groups based on auditory sensitivity. the interventions were home-based, guided by digital content through the moodle platform, and lasted four to six weeks depending on the protocol. the cce+t-bb group also received 10-minute daily auditory stimulation designed to modulate brainwave activity and support emotional regulation. the study used both objective (sensory organization test - sot) and subjective (dizziness handicap inventory - dhi, state-trait anxiety inventory - stai) tools to assess outcomes before and after the interventions. all groups showed improvements, but the cce+t-bb group demonstrated superior gains in balance, especially under visually and vestibular-dependent conditions. both cce-based groups had significant reductions in trait and state anxiety, while the bde group only showed improvement in trait anxiety. these findings suggest that structured vestibular rehabilitation improves balance and reduces anxiety in patients with residual dizziness. furthermore, adding auditory neuromodulation (t-bb) to cce may enhance postural adaptation and emotional regulation, supporting a multimodal, non-pharmacological approach to rd management. this research represents the first clinical evaluation of theta binaural beats as an adjunct to vestibular therapy and offers a promising direction for personalized rehabilitation.
