The authors compared the efficacy of a self-applied modified Semont maneuver (MSM) with self-treatment with a modified Epley procedure (MEP) in 70 patients with posterior canal benign paroxysmal positional vertigo. The response rate after 1 week, defined as absence of positional vertigo and torsional/upbeating nystagmus on positional testing, was [size=130]95% in the MEP group[/size] (n = 37) vs 58% in the MSM group (n = 33; p < 0.001). Treatment failure was related to incorrect performance of the maneuver in the MSM group, whereas treatment-related side effects did not differ significantly between the groups.
