Effects of photobiomodulation associated with vestibular rehabilitation in the treatment of patients with vestibular symptoms and tinnitus: a triple-blind randomized clinical trial.
Trial report in CoDAS, 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
purposeTo analyze the effects of photobiomodulation (PBM) associated with vestibular rehabilitation (VR) in adults with vestibular symptoms and tinnitus, compared to VR combined with placebo PBM, regarding the reduction of tinnitus discomfort and improvements in vestibular function, postural balance, and dynamic visual acuity.
methodsRandomized, triple-blind clinical trial with 20 volunteers diagnosed with vestibular hypofunction and chronic tinnitus. Participants were allocated into two groups: research group (RG), which received VR combined with active PBM; and control group (CG), which received VR combined with placebo PBM. Both groups underwent ten intervention sessions, twice a week, over five weeks. Pre- and post-intervention assessments included: Tinnitus Handicap Inventory (THI), Dizziness Handicap Inventory (DHI), Visual Analog Scale (VAS), dynamic visual acuity (DVA) test, and posturography. Data were analyzed using Student's t-test and the Mann-Whitney test (p<0.05).
resultsIn the post-intervention comparison between groups, the RG showed significant improvement in VAS for tinnitus (p=0.046), and in the functional (p=0.003), emotional (p=0.002), and total (p=0.000) scores of the THI. The Sensory Organization Test parameter showed a significant pre- and post-treatment difference (p=0.003) only in the RG. VAS for vestibular symptoms, DHI scores, and the Composite Equilibrium Score improved in both groups, with no significant difference between them.
conclusionPBM combined with VR significantly reduced tinnitus discomfort and showed superior performance in vestibular function analysis. VR alone did not demonstrate any effect on tinnitus reduction.
