Educational quality of YouTube videos on scapular dyskinesis: a cross-sectional analysis.
Article in Clinics in shoulder and elbow, 2025. 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
backgroundYouTube is a widely accessible platform that facilitates the rapid dissemination of both evidence-based and potentially misleading health-related information. This study assesses the educational quality, reliability, and comprehensiveness of the most-viewed YouTube videos about scapular dyskinesis.
methodsA systematic search was conducted on YouTube using the keywords "scapular dyskinesia" and "scapular dyskinesis." The top 100 videos for each keyword were screened for inclusion, and the metrics, sources, and content of the included videos were analyzed. Video quality and reliability were assessed using the Global Quality Scale and the modified DISCERN scale, respectively. In addition, a newly developed, non-validated tool, Scapular Dyskinesis Specific Scoring, was used to provide a condition-specific content assessment.
resultsThe analysis revealed that 48.1% of the videos were low quality, and 62.0% lacked reliability. Videos produced by health-related websites exhibited superior quality. Content focusing on treatment and diagnostic approaches demonstrated significantly higher quality than other content categories (P<0.001). A correlation analysis indicated that the Video Power Index did not correlate significantly with reliability, quality, or comprehensiveness scores. Additionally, a simple regression analysis revealed that the video upload time negatively affected the quality, reliability, and comprehensiveness metrics.
conclusionsMost YouTube videos on scapular dyskinesis were of low quality, lacked reliability, and failed to provide comprehensive and accurate information. Furthermore, high-quality and reliable content tended to receive relatively low engagement and user preference scores. These findings underscore the urgent need for well-structured, evidence-based, and regularly updated YouTube content about scapular dyskinesis. Level of evidence: IV.
