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

Abstract

Background: 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 employs DISCERN and JAMA scoring systems to evaluate video quality and explores potential differences between physician and non-physician contributors. Methods: The study screened the first 50 YouTube videos containing "frozen shoulder" in titles, excluding short, repetitive, and non-English content. Videos were categorized by content type, uploader, and key metrics recorded. Two observers independently scored videos using DISCERN and JAMA systems. Statistical analysis, including Mann-Whitney tests and Spearman correlation, assessed differences and agreement. Results: Among 50 videos, 45 featured real images, while 5 were animated. Physical therapists contributed the most (40%), and 60% focused on general information. Mean DISCERN and JAMA scores indicated predominantly poor quality. No significant differences were found between physician and non-physician videos. Observer agreement was excellent. Conclusion: Patients accessing YouTube for frozen shoulder information face challenges in discerning reliable content. Health professionals should contribute accurate videos, guiding patients to trustworthy online resources. Further research in orthopedics and other medical fields is essential to enhance the quality of health-related video content.
