Assessment of vestibulo-ocular reflex function in people with Parkinson's disease: a cross-sectional study in a rehabilitation setting using the video head impulse test.
Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
backgroundParkinson's disease (PD) is a neurodegenerative, progressive disorder known for motor and non-motor symptoms. The vestibular system, via the vestibulo-ocular reflex (VOR), is crucial for maintaining dynamic gaze stability, and its role in PD is raising interest among researchers. Indeed, vestibular dysfunction in PD may exacerbate postural instability and gait disturbances; however, the prevalence of vestibular dysfunctions remains unclear. This study aims to objectively investigate the VOR function in people with PD using the video head impulse test.
methodsThis is a cross-sectional study conducted in a neurorehabilitation hospital. People with PD were included if they had no cognitive impairment and the ability to walk without physical assistance. The video head impulse test was used to assess the VOR function across all six semicircular canals, using both the Head Impulse Paradigm (HIMP) and the Suppression Head Impulse Paradigm (SHIMP) paradigms.
results35 people with PD (mean age: 69.9±8.4; 11 females) with moderate motor symptoms (MDS-UPDRS-part III: 27.7±6.8) were included. Using normative cut-offs, 69% of the participants had at least one dysfunctional canal (60% hypo-gain, 9% hyper-gain). The prevalence reached 83% when both the HIMP and SHIMP paradigms were considered.
conclusionThere is a high prevalence of vestibular dysfunction in people with PD. The instrumental assessment of VOR gains could reveal undiagnosed vestibular dysfunctions and, in the future, lead to more specific rehabilitation management of people with PD.
