Assessment of YouTube Videos on Frozen Shoulder: A Quality Analysis Using DISCERN and JAMA Scoring Systems

Abstract

Aim: Frozen shoulder, characterized by synovial inflammation and joint capsule fibrosis, impacts shoulder mobility and comfort. With the rise of online health information seekers, assessing the credibility of YouTube videos on frozen shoulder is crucial. This study aims to explore potential differences between physician and non-physician contributors by assessing the quality of Youtube videos using the DISCERN and JAMA scoring systems. Methods: The first 50 YouTube videos found by searching with the word "Frozen shoulder" were examined; Short, repetitive titles and non-English content were not included in the study. Videos were categorized by content type, uploader, and key metrics of the videos were recorded. Two observers independently scored the videos using DISCERN and JAMA systems.Statistical analysis was performed, including Mann-Whitney tests and Spearman correlation.. Results: While 45 of the 50 videos contained real images, 5 were animations. Physiotherapists were the most contributing group (40%), and 60% of the videos contained general information about frozen shoulder. Considering the average DISCERN and JAMA scores, videos were mostly rated poor in quality. No statistically significant differences were found between the videos uploaded by physicians and non-physicians. Observer agreement was excellent. Conclusion:Internet users searching for information about frozen shoulder face difficulties in distinguishing reliable content. Healthcare professionals should share videos with accurate information and direct patients to reliable online resources..
