Objective: In this study, we aimed to investigate reliability and utility of videos accessed with ‘Senior Physical Therapy’ term on YouTube in terms of medical information.

Material and Method: ‘Senior Physical Therapy’ term was screened on YouTube. The non-english videos, advertisements, videos shorter than 45 seconds, repeated two or more times,
and the videos with an irrelevant content were excluded, and the most viewed 50 videos were evaluated by two independent orthopedists according to DISCERN (Quality Criteria for Consumer Health Information) and JAMA (Journal of the American Medical association) scoring systems. The correlation between the observers was assessed with Spearman Correlation Analysis, and the compliance with Krippendorff α. According to the normality results, non-parametric Kruskal-Wallis Variance Analysis test was applied. p<0.05 values considered statistically significant (p<0.017 values at Bonferroni-Correction Mann-Whitney U test).

Results: The videos was most commonly upload by health channels (66%) and physiotherapists (14%). A strong statistically significant correlation was found between DISCERN (r:0.971, p<0.001) and JAMA (r:0.808, p<0.001) scores of the observers. The compliance between two observers was high in DISCERN scores (Krippendorff α.: 0.970) and moderate in JAMA scores (Krippendorff α.: 0.792). DISCERN scores of the videos uploaded by physiotherapist were highest. Of the 50 videos, 70% was determined as poor, 28% very poor and 2% fair in terms of the information content.

Conclusion: Preparation of the videos with medical contents by specialized person and based on references may increase the quality of information obtained via the social media.
