Vemp test left side abnormal halp
my right ear OVEMP was weird ! but scans showed nothing. what did it end up being for you?
Why you have marked P1 in downward....... In my opinion it must be N10 instead of P1. Please clear my doubt......
Hello! As we have used montage where active electrodes were connected to the minus channels of the device we got positive polarity (P) orienting downward and negative polarity (N) orienting upward. If you will connect active electrodes to the plus channels you will get positive polarity orienting upward and negative polarity (N) orienting downward. In cervical VEPM we register two main peaks: firstly P1 (the same as P13) and after it N1 (the same as N23).
