Most videos (82%) provided accurate time spent on each position. The researchers rated almost two thirds of the videos (64%) as accurate demonstrations of the maneuver. That video, along with 4 others, accounted for 85% of hits for all videos. The most widely viewed video (with 802,471 hits) was produced in 2008 by the Practice Parameter on BPPV of the American Academy of Neurology (AAN). The total number of hits for all videos was 2,755,607. Most seemed to have been made by healthcare providers, including physicians and physical therapists, but some were likely made by patients in their home. ![]() ![]() The videos appeared to come from a number of different sources, said Dr. Researchers also determined whether the videos included diagnostic information and were accurate in the time spent on each position of the maneuver (most should last at least 20 seconds). They categorized the videos as demonstrating guided treatment or self-treatment, and as showing the maneuver for right-sided BPPV, left-sided BPPV, or both. “There haven’t been that many studies looking at this, but every one of them suggests that this maneuver is underutilized.” It is possible that physicians recommend the maneuver but just do not record it, he said.Īfter performing a systematic search and selecting videos that demonstrated the entire Epley maneuver and that were available on YouTube up to August 30, 2011, researchers abstracted information from each video, including its duration, posting date, and number of views, and related comments from viewers. Kerber, however, this treatment is not widely used. “If you want to treat someone effectively, this is it.”Īccording to Dr. The maneuver has been proven effective in rigorous randomized trials and is included in guidelines on treating BPPV, said Dr.
