Youtube As A Source Of Information For Otago Exercises

Abstract This study aimed to assess the quality and reliability of the most-watched YouTube videos on Otago exercises. The keywords “Otago exercise” and “Otago exercise program” were searched between December 15-30, 2023. Sixty videos were selected for each keyword, sorted by number of views. Video metrics and upload sources were documented. The modified (m) DISCERN score and the Global Quality Score (GQS) were used to evaluate the reliability and quality of the videos, respectively. Out of the 34 videos reviewed, the majority (47.1%) were shared by physiotherapists. The median mDISCERN score was 2, indicating that a significant proportion (79.4%) of the videos exhibited low reliability (p<0.05). The median GQS score was 3, with 64.7% of videos classified as intermediate or high quality. However, no statistical differences in quality were observed (p>0.05). Although no statistical difference was noted, it was evident that physiotherapists uploaded a higher percentage of reliable and high-quality videos compared to other sources. Analysis of the video metrics among the quality groups revealed significant differences only in video duration (p<0.05). Positive correlations were found between certain video metrics and mDISCERN (video duration, number of comments) and GQS (video duration) scores. YouTube videos on OTAGO exercises demonstrate insufficient reliability and quality. Collaboration with professional organizations in geriatric rehabilitation is recommended for YouTube to produce high-quality and reliable videos aligned with their evolving health content policy.
