A Blinded, Controlled Randomized Clinical Trial on the Efficacy of Neck Muscle Vibration in Patients with Post-Stroke Spatial Neglect.
Trial report in Neurorehabilitation and neural repair, 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 AND
aimUnilateral spatial neglect (UN) impairs patients' ability to detect and respond to stimuli on the contralesional side, severely limiting functional recovery after right-hemispheric stroke. Neck muscle vibration (NMV) has been shown to be a bottom-up, proprioceptive intervention to modulate spatial neglect. Although preliminary studies found promising effects, the isolated efficacy of NMV for neglect rehabilitation has not yet been tested in a randomized, blinded controlled trial. This study aimed to evaluate whether NMV alone improves neglect symptoms and activities of daily living (ADL).
methodsTwenty patients with right-hemispheric stroke and UN were randomly assigned to receive either active or placebo NMV (combined, but not simultaneously with computer-based training) over 2 weeks (5 sessions/week, 20 minutes/day). In the computer training, the placebo NMV group completed neglect-specific modules (standard neglect therapy [SNT], e.g., visual exploration training), while the active NMV group performed only general cognitive tasks unrelated to neglect. This allowed the isolated effect of NMV to be examined. Assessments included standard neglect diagnostics (e.g., Letter Cancellation), the Free Exploration Test (FET), and 2 ADL-based measures (NET, CBS), conducted before, immediately after, and (NMV group only) 1 month post-treatment.
resultsThe active NMV group showed significant improvements in 3 of 4 standard neglect tests, exploration behavior (FET), and ADL performance, with effects remaining stable at 1-month follow-up. The SNT group with placebo NMV showed comparable gains in ADL outcomes but improved in 1 standard neglect test only. Between-group analyses revealed no statistically significant differences, suggesting similar efficacy of both interventions.
conclusionNMV alone yields clinically meaningful and lasting improvements in neglect symptoms and ADL, comparable to SNT. Its passive nature makes it a promising tool, particularly for early rehabilitation.
