Effect of Repositioning Maneuver Type and Postmaneuver Restrictions on Vertigo and Dizziness in Benign Positional Paroxysmal Vertigo

Table 2

Comparison of liberatory signs in Epley (Ep) and Semont-Toupet (ST) maneuver sequences. The sequence was stopped after vertigo and nystagmus. These signs more frequently observed after ST than after Ep (70% versus 51%, 𝑃 < 0 . 0 0 1 , Fisher’s exact test). ST as a 3rd maneuver also yielded a higher rate of liberatory signs than Ep (12%, versus 3%, 𝑃 < 0 . 0 2 , Fisher’s exact test).
