![]() In two prospective randomized tri-national studies, it was demonstrated that the SM+ is superior to (A) the regular SM: in the 194 patients analyzed, it took 2 days (median, mean: 3.6 days) for recovery with SM and 1 day (median, mean: 1.8 days) with SM+ (p=.001, 2-sided Mann-Whitney-U-test and In this way, the otoconia move 60°+ further in the direction of the utricle, which should theoretically increase the effectivity. Based on these findings, the Semont-Plus (SM+) was developed: the patient’s body is moved towards the affected side 60°+ below earth horizontal. A biophysical model and computer simulations showed that during the rotation of the labyrinth the crystals move about 25° less than the rotation of the canal. However, a meta-analysis concluded that many patients suffer longer and are more impaired than previously assumed. For its treatment, there is Level 1 evidence that the Semont maneuver (SM) and the Epley maneuver (EM) are effective. ![]() Most often the posterior canal is affected: pcBPPV.
