As discussed in the podcast, the Epley Maneuvers can be used and have been shown to be helpful in the treatment of benign paroxysmal positional vertigo (BPPV).
They found 33 videos demonstrating the Epley maneuvers, but only 21 (64%) of the videos were deemed accurate. They also noted that a large number of comments under the videos were from patients with the condition self treating by watching the video, and commented that YouTube offered an interesting way to disseminate "effective interventions such as the EM" to patients. I think it is safe to say the EM community figured out the utility of YouTube and social media in education some time ago.
Here is the video they deemed mot often used and most accurate (from the American Academy of Neurology).
Here is a claymation video I find more entertaining.
