Design and preliminary evaluation of a VR-based optokinetic stimuli system for vestibular rehabilitation: insights from clinical end users.
Article in Frontiers in medicine, 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
Background: Vestibular therapy is essential for treating dizziness and balance disorders. There is growing evidence supporting the benefits of incorporating Virtual Reality (VR) into vestibular therapies. Objective: To gather feedback from neuro-rehabilitation specialists on an optokinetic virtual environment (OVE). Methods: An OVE modeled after the traditional optokinetic drum was developed for commercially available VR headsets and tested by practicing vestibular therapists. Participants completed a Likert-based survey and semi-structured interviews to assess their perceptions of the OVE. Qualitative data were analyzed thematically. Results: Ten therapists with an average of 9 years of clinical experience (range: 3-15 years) participated from October 2024 to March 2025. The likelihood of using the OVE in clinical practice was rated highly, with Likert scores ranging from 6 to10 (median = 9), where 10 indicated a high likelihood. Five key themes emerged for potential improvements: (1) Clinical Usability and Setup, (2) Control and Customization, (3) Immersive Design and Realism, (4) Output and Measurement Preferences, and (5) Implementation Barriers. Conclusion: Vestibular rehabilitation clinicians expressed strong interest in utilizing VR-based optokinetic stimuli. Feedback from this study will inform iterative, user-focused application improvements. Future studies will test the improved OVE with patients to evaluate tolerance, efficacy, and usability.
