As a model, we observed predictors that were significant (cVEMP AR and oVEMP AR).
The results showed that oVEMP AR was the only significant diagnostic indicator of recurrence (77.8% sensitivity, 94.9% specificity, p=0.002) (Table 7, Fig.
A significant increase in the amplitude on the affected side occurred after repositioning procedure at oVEMP points to the return of detached otoconia just in the area of utricle.
From the clinical point of view, oVEMP appears to be better suited for testing PC-BPPV than cVEMP (27).
According to our results, the oVEMP AR was the only significant diagnostic predictor of recurrence.
The increase in the oVEMP amplitude on the affected side after successful repositioning procedure confirmed the hypothesis on the return of otoconia into the area of the utricular macula.
A "standard" OVEMP recording (using our usual clinical protocol described above) without looking at the number of sweeps to test for the recordability of the OVEMP from the participant.
OVEMP recording with twice as many sweeps (54 sweeps).
The amplitudes of the OVEMP recordings under each collection parameter are shown in Table 2.
The present study demonstrates that OVEMP latencies do not change when different numbers of sweeps are used.
It has also been shown in both guinea pigs  and humans  that there are potentially deleterious effects of prolonged noise exposure at the level required to perform the OVEMP assessment.
Our main study demonstrates that OVEMP amplitude is larger with fewer stimuli, and if comparative stimuli from side to side are used to measure asymmetry, this method is helpful in preventing attenuation and perhaps disappearance of the response due to overstimulation.
