Analysis of YouTube content as an information source for femoroacetabular impingement rehabilitation

This study aims to evaluate the content, reliability, and quality of YouTube videos related to the rehabilitation of Femoroacetabular Impingement (FAI). A systematic evaluation of YouTube videos was conducted, assessing video attributes and upload sources. Two physiotherapists independently classified the videos as either useful or misleading. The comprehensiveness of the videos was analyzed using a 10-item scale, reliability was assessed with the 5-point modified DISCERN (mDISCERN) scale, and overall quality was evaluated using the Global Quality Scale (GQS). A total of 74 videos were included in the analysis, of which 26 (35.1%) were categorized as useful, while 48 (64.9%) contained misleading information. The useful videos exhibited significantly higher mean scores in comprehensiveness, reliability (mDISCERN), and overall quality (GQS) compared to misleading videos (p < 0.05). Furthermore, a significant difference in mDISCERN scores was observed between videos uploaded by health professionals and non-health professionals (p = 0.042). However, no statistically significant differences were found in comprehensiveness (p = 0.245) or quality (p = 0.068) scores. This study highlights the substantial prevalence of misleading information in YouTube videos related to FAI rehabilitation. To mitigate this issue, healthcare professionals, including physiotherapists and physicians, should actively contribute by producing accurate, evidence-based video content to ensure the dissemination of reliable and high-quality information on this topic.
