Reviewing the contents of youtube hemiplegia exercise videos

Our study was carried out in order to examine the content of hemiplegia exercise videos on the YouTube video sharing platform and to evaluate their quality. In the study, 180 videos scanned with the keywords 'hemiplegia exercises', 'hemiplegia rehabilitation' and 'hemiplegia physiotheraphy' were evaluated. 37 videos which are in English with meaningful audio were included in the study. For each video duration, to the length of time since its publication, video power index, number of likes, number of dislikes, source, number of comments, number of views and view rate were recorded. The quality of the videos was evaluated via the Global Quality Scale (GQS) and the videos' reliability via the Journal of the American Medical Association (JAMA) by three physiotherapists having different professional experiences. ( physiotherapist 1 (3 years), physiotherapist 2 (5 years), and physiotherapist 3 (10 years)). According to the GQS, the videos were separeted into 2 groups as low, medium and high quality. According to the sources who uploaded the videos, they were divided into 2 different categories. In addition, the correlation level of the JAMA and GQS scores given by the evaluators was checked. As a result of the study, 43.24% of the videos were found to be low quality, 56.75% medium quality and high quality. It was seen that quality of all videos (GQS) median is 3 (1-4), which is high, and the reliability of all videos (JAMA) median is 2 (0-4), which is low. In the validity of the giving answers for the GQS and JAMA scores inter evaluators, ICC=0,766 and ICC=0,793 were founded high. The number of the comments in the videos, which have high and medium quality, the physiotherapist 2's GQS score (p=0,023 is high considering the low quality videos. The physiotherapist 2 JAMA score (p=0,001), and the number of comments on the videos, which were loaded by physiotherapists, are high considering the sources, however, the elapsed time after the video loading (p=0,001) is low. There was no significant difference between the other parameters of the videos (p>0.05). YouTube Hemiplegia exercise videos have low reliability and may not be appropriate as a reliable source for patients. Healthcare professionals are required to publish videos that meet GQS and JAMA, and YouTube is required to publish videos with filtering. Keywords: YouTube, Hemiplegia, Exercise, Content, Reliability
