Background: Online health-related information has become increasingly popular. Social media platforms have great potential to support and change patients’ perspective. Plantar fasciitis (PF) is a common disease that is one of the most frequently researched subjects among foot problems. This study aimed to assess the content, quality, and reliability of YouTube videos related to PF and to evaluate whether they reflect current PF treatment guidelines.
Methods: The descriptive cross-sectional study analyzed the most viewed 79 YouTube videos retrieved by using the keyword “plantar fasciitis.” The quality, reliability, and content of the videos were analyzed using Global Quality Scale (GQS), the modified DISCERN instrument, the Journal of the American Medical Association instrument, and a content scoring system by two independent physiotherapists. The analyzed videos were divided into three groups according to their GQS score as high, intermediate, and low quality. Also, video parameters were compared between the useful and misleading groups.
Results: Of the 79 analyzed videos, 26 (32.9%) were of low quality, 29 (36.7%) were of intermediate quality, and 24 were of (30.3%) high quality. Most high-quality videos were uploaded by allied health professionals (39.4%). The view ratio and video power index scores were highest in patients. There were significant differences between useful and misleading videos in terms of DISCERN, GQS, and Journal of the American Medical Association scores (P = .000, P = .000, and P = .020, respectively). Almost all of the evaluated videos contain at least one treatment approach.
Conclusions: This study demonstrates that the vast of majority of YouTube videos on PF are useful and comprehensive; also, our results may lead us to propose that the vast majority of the videos reflect current treatment guidelines. Video-based information about PF may provide valuable insight to patients, especially in the absence of direct access to health care by stakeholders.
