5.3.1 Edit Tab

Under the Edit tab, it is possible to view the EMG contractions for single curves or for the right and left ear
VEMP partners (indicated by 95a on the curve handle). All EMG contractions over a waveform recording can
be displayed here and printed out.
1. Marking peaks
Peaks and troughs can be marked during and after testing in the Record tab and in the Edit tab. Simply right
click on the curve and the window below will show up. From here it is possible to set P1, N1, P1', and N1'.
The P1 and N1 markers are available for marking the positive and negative peaks of the wave. In addition,
P1' and N1' markers are available when multiple tracings of the same intensity have been run. Since laten-
cies are highly variable between patients we have opted to use P1 and N1 instead of P13 and N23. Absolute
latency and amplitude data are displayed on the left hand side of the screen after waves have been marked.
The cVEMP response is well documented in the literature and is said to be represented by two distinct
peaks; P1 occurring at approximately 13ms and N1 occurring at approximately 23 msec.
The oVEMP response is also well documented in the literature and is said to be represented by two distinct
peaks; N1 occurring at approximately 10ms and P1 occurring at approximately 15ms.
