Abstract
Background: Exercise is a widely recommended non-pharmacological approach to improve physical function and quality of life in individuals with multiple sclerosis (MS). With the growing use of digital platforms, YouTube has become a popular resource for health-related information and exercise guidance. This study aimed to evaluate the content quality and reliability of YouTube videos offering exercise guidance for individuals with MS. Methods: This search was conducted using relevant keywords, and videos were screened based on inclusion criteria. Content quality was assessed using the mDISCERN scale, Global Quality Score (GQS), and Journal of the American Medical Association (JAMA) benchmarks. Video characteristics, including duration, number of views, and uploader type, were also recorded. A total of 95 videos met the criteria. Results: Among included videos, 18 % were rated low quality, 37 % moderate, and 45 % high quality. The most common upload sources were commercial accounts (n = 28), non-commercial organizations or community groups (n = 19), and physiotherapists (n = 16). Significant differences were found in mDISCERN and JAMA scores between low-, moderate-, and high-quality groups (p < 0.001 and p = 0.008, respectively). Strengthening exercises (n = 21), informational videos (n = 16), and other exercises (n = 15) were the most frequently presented. Conclusion: In conclusion, while YouTube serves as an accessible platform for MS-related exercise content, the variability in video quality and presence of non-expert uploads may mislead viewers with low e-health literacy. High-quality, evidence-based content provided by professionals is essential to support safe and effective exercise in individuals with MS.
