Can YouTube be used as an educational tool in lymphedema rehabilitation?
Okan Küçükakkaş, Buğra İnce
PMID 35236412WHAT IT FOUND
Most YouTube videos on lymphedema rehabilitation were low quality, with poor sourcing and missing safety information.
Educational videos for professionals and those from universities scored higher than patient videos or manufacturer ads, but overall reliability remained insufficient for safe self-guidance.
Key findings
01The average educational quality score was 2.7 out of 5, and reliability was 2.2 out of 5, with only 6 videos rated excellent.
02Videos uploaded by universities and educational videos for healthcare professionals had significantly higher quality and reliability scores compared to patient information videos and manufacturer content.
03Most videos failed to cite valid sources or address areas of uncertainty, with only 10 of 90 videos citing valid sources.

What it does not show
There are no validated tools for assessing video quality, so the GQS and modified DISCERN scores rely on subjective judgment. The search was limited to the first three pages of results sorted by relevance, which may be influenced by YouTube's algorithm and advertisements. The study represents a snapshot in time (April 2021); video availability and quality change frequently as content is added or removed. Only English-language videos were included, limiting the generalizability to non-English speaking populations.
Declared interests
The study did not include any human participants. No specific funding sources or conflicts of interest were declared in the provided text.
The easy way to misread this
Do not interpret the correlation between view counts and quality as evidence that popular videos are accurate. The study found that high-quality videos were rare, and the most viewed video was not necessarily the most reliable, so popularity is not a proxy for safety in lymphedema care.
