YouTube Videos Might Help Ease Form of Vertigo

MONDAY, July 23 (HealthDay News) — Videos posted on YouTube
might come to the rescue of people suffering from a common cause of
vertigo, a new study shows.

Vertigo is the sensation that everything around you is moving or
spinning, even though you’re stationary.

This study looked at benign paroxysmal positional vertigo (BPPV), an
inner ear disorder that is a common cause of this type of dizziness. It
often goes untreated by doctors even though it’s easily and quickly
remedied with a simple technique called the Epley maneuver.

BPPV occurs when loose calcium carbonate crystals move into the sensing
tubes of the inner ear. The maneuver uses gravity to move the calcium
crystals out of the sensing tube and into another inner chamber of the
ear, where they do not cause symptoms.

U.S. researchers found that accurate video demonstrations of the
maneuver are readily available on YouTube, according to the study in the
July 24 issue of the journal Neurology.

“It was good to see that the video with the most hits was the one
developed by the American Academy of Neurology when it published its
guideline recommending the use of the Epley maneuver in 2008 and then
posted on YouTube by a lay person,” study author Dr. Kevin Kerber, of the
University of Michigan Health System in Ann Arbor, said in a journal news
release.

“But it was also good that the majority of the videos demonstrated the
maneuver accurately,” he added.

The researchers also found that some comments accompanying the videos
show that health care providers are using the videos as a prescribed
treatment for BPPV or to help patients learn the Epley maneuver.

“One shortcoming of the videos was that they did not include
information on how to diagnose BPPV, and some of the comments indicate
that people who do not have BPPV may be trying these maneuvers because of
dizziness from other causes,” Kerber said. “Despite this, we found it
encouraging to think that YouTube could be used to disseminate information
about this maneuver and educate more people about how to treat this
disorder.”

Another expert agreed that a physician’s diagnosis is key.

“The Epley Maneuver is, indeed, an effective treatment for BPPV [and] a
‘do-it-yourself’ video may increase the number of patients treated, ” said
Dr. Ronald Kanner, chair of neurology at Long Island Jewish Medical Center
in New Hyde Park, N.Y. and North Shore University Hospital in Manhasset,
NY.

But he added that, “for a procedure to be effective, the diagnosis
needs to be made correctly and the treatment applied appropriately. While
the authors helpfully describe what is likely to become a significant
trend, we must exercise caution in self-diagnosis and self-treatment.
Furthermore, patients may experience extreme dizziness, following the
procedure and it should not be done without a watchful eye to protect the
patient.”
