[22] The present study demonstrates a decrease in vertiginous symptoms among the control group with time, although the controls did not demonstrate a corresponding resolution of the Dix-Hallpike test. It is therefore theorized that the resolution of vertigo in untreated patients is the result of avoidance of vertigo-producing head positions. In other words, these patients still have BPPV but have reduced their freedom of movement to remain asymptomatic (Liu, Wang, Zhang, and
