YouTube as a resource for Parkinson's disease exercise education: an evaluation of video quality and reliability.
Article in BMC medical education, 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
backgroundYouTube is a common platform for sharing exercise content related to Parkinson’s disease (PD) and is increasingly used as an informal educational resource for patient education and health professional learning.
methodsA cross-sectional, video-based study was conducted between October and November, 2025. Using the keyword ‘Parkinson’s disease exercise’, the first 50 eligible videos were analyzed after minimizing bias. Each video was categorized by source and rated for educational accuracy as “useful,” “misleading,” or “harmful” in the context of exercise education. Viewer metrics (views, duration, likes, comments, subscriber count etc.) were recorded. Educational quality and reliability were assessed using the Modified DISCERN tool, JAMA benchmarks, HONcode, and the Global Quality Scale (GQS). Two researchers independently evaluated videos, with correlation, ICC, and ROC analyses applied to assess consistency.
resultsOf the 50 videos, 34 (68%) came from institutional channels, 13 (26%) from health professionals, and 3 (6%) from other sources. Regarding educational accuracy, 29 (58%) videos were classified as useful educational resources, 18 (36%) as misleading but not harmful, and 3 (6%) as potentially harmful for PD exercise education. The mean number of views was 292487.38 ± 672016.99, with an average duration of 19 min. The mean educational quality scores were 2.4 for mDISCERN, 2.3 for JAMA, 2.3 for GQS, and 8.2 for HONcode. ICC showed good-to-excellent agreement (0.771–0.955). ROC analyses indicated that mDISCERN (AUC: 0.843–0.917) and GQS (AUC: 0.759–0.818) effectively distinguished useful videos, while JAMA and HONcode were less discriminative.
conclusionMore than half of the videos were identified as potentially useful educational resources for PD exercise education, particularly those produced by institutional or health professional sources; however, many lacked sufficient evidence-based structure to support effective patient or professional education. mDISCERN and GQS emerged as the most effective tools for evaluating the educational quality of exercise-related video content.
