Abstract—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 95% in the MEP group (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.
