Table 2. Mean (±SD) latencies of cVEMP induced by STB and clicks (P13 and N23) and of oVEMPs induced by AC STB and BCV (AFz and mastoid; n1 and p1), in healthy subjects, 63 patients with non-operated VS (affected and intact side) and 20 patients after surgery for VS (intact side).

VEMP tests	Stimulation	Healthy subjects	Non-operated VS affected side	Non-operated VS intact side	Operated VS intact side
cVEMP latencies (ms)	AC STB P13	14.8±1.0	14.7±1.4 n = 29	14.8±1.3 n = 60	14.6±0.9
	AC STB N23	21.6±1.3	21.5±2.3	21.9±1.8	21.2±1.2
	AC clicks P13	11.9±1.1	12.7±1.9 n = 12	12.1±1.7 n = 41	12.1±1.2
	AC clicks N23	18.3±1.6	18.7±3.1	18.1±2.1	18.2±1.2
oVEMP latencies (ms)	AC STB n1	11.2±0.8	11.3±0.7 n = 12	11.2±0.7 n = 37	11.6±0.6
	AC STB p1	15.3±1.0	14.9±1.5	15.1±1.2	16.2±1.3
	AFz BCV n1	11.2±0.8	11.4±0.8 n = 17	11.2±0.8 n = 50	11.1±0.7
	AFz BCV p1	15.2±1.1	14.8±1.7	14.9±0.9	15.0±0.8
	Mastoid BCV n1	10.9±0.7	11.5±1.4 n = 25	11.15±1.3 n = 60	10.8±0.5
	Mastoid BCV p1	15.3±1.0	15.5±2.4	15.3±1.7	14.6±0.6

Note that no significant differences were detected in the latencies of P13, N23 and n1-p1 between healthy subjects and VS patients.
