Targeted Vestibular Rehabilitation Accelerates Symptom Relief by Promoting Vestibular Compensation in BPPV Patients With Residual Symptoms: Evidence From Resting-State fMRI.
Article in Brain and behavior, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimsResidual dizziness (RD) is commonly observed in patients with benign paroxysmal positional vertigo (BPPV) following successful canalith repositioning procedures. Targeted vestibular rehabilitation therapy (tVRT) is a novel strategy designed to address specific vestibular deficits. This study aims to investigate whether tVRT can accelerate the vestibular rehabilitation process in patients with RD of BPPV and explore its neural mechanisms.
methodsNinety-four BPPV patients with RD were enrolled and received a 4-week tVRT program tailored to utricular deficits. A rs-fMRI subgroup (n = 43) was used to assess brain activity and functional connectivity (FC) before and after successful intervention.
resultsThe tVRT group demonstrated significantly lower DHI and SAS scores and higher ABC score. rs-fMRI revealed that tVRT increased ALFF in the right superior temporal gyrus (STG), positively correlated with ABC scores, and enhanced ReHo in the right anterior cingulate cortex (ACC). The tVRT group showed enhanced STG-cerebellar tonsil connectivity, along with reduced STG-posterior cingulate cortex connectivity. Using right ACC as seed, FC between the ACC and lingual gyrus was increased. STG-cerebellar tonsil FC was negatively correlated with RD duration.
conclusiontVRT accelerates vestibular compensation in patients, which may be mediated by enhanced neural activity and reorganization of brain networks involved in vestibular processing.
