Are repositioning maneuvers effective in benign paroxysmal positional vertigo (BPPV)?
Can having someone move you around into different positions really get rid of vertigo? A group of researchers wanted to find out just that, so they analyzed studies on repositioning maneuvers. What they concluded: Yes, this treatment approach helps.
The Epley and Semont maneuvers are sequences of movements that involve turning your head and changing the position of your torso. They are used in the treatment of benign paroxysmal positional vertigo (BPPV). The aim is to get rid of vertigo caused by tiny crystals in the organ of balance. The maneuvers are thought to cause the loose crystals to stay in one place, where they no longer trigger episodes of vertigo and can be broken down by the body.
Research on effectiveness
Researchers from the Cochrane Collaboration – an international network of researchers – analyzed eleven studies on the Epley maneuver. Nearly 750 adults who had BPPV took part in these studies.
The results show that the Epley maneuver is very likely to get rid of this type of vertigo. After up to four weeks, a comparison of the two groups showed the following:
- The BPPV symptoms had gone away in 20 out of 100 people who didn’t use the maneuver,
- compared to 52 out of 100 people who did use the Epley maneuver.
This means that the Epley maneuver prevented further episodes of vertigo in an additional 32 out of 100 people.
Studies comparing the Epley maneuver with the Semont maneuver found that the two approaches are equally effective.
Because the repositioning maneuvers didn’t cause any serious complications in the studies, researchers assume that they are safe. Typical side effects include vertigo or nausea because the maneuvers sometimes lead to episodes of vertigo themselves.
