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 < 0.001, Fisher's exact test). ST as a 3rd maneuver also yielded a higher rate of liberatory signs than Ep (12%, versus 3%, P < 0.02, Fisher's exact test).

	Maneuver sequences
	Epley (n = 113)	Semont-Toupet (n = 113)
Liberatory signs after 1st maneuver	Ep: 45 (40%)	ST: 65 (58%)
Liberatory signs after 2nd maneuver	Ep: 13 (12%)	ST: 14 (12%)∗∗∗
Liberatory signs after alternate maneuver	ST: 14 (12%)∗	Ep: 3 (3%)
No liberatory signs after alternate maneuver	41 (36%)	31 (27%)

^∗∗∗ P < 0.001, proportion of liberatory signs after one or two ST versus Ep maneuvers, Fisher's exact test.

^∗ P < 0.05, proportion of liberatory signs after alternate ST maneuver versus Ep, Fisher's exact test.
