The Effects of Electrode Montage on the Amplitude of Wave V in the Auditory Brainstem Response to Maximum Length Sequence Stimuli
The use of maximum length sequence (MLS) stimuli to elicit an auditory brainstem response (ABR) has been limited, in part, by the observation that these stimuli reduce ABR wave amplitudes. This study recorded ABR waveforms from 14 normally hearing adults using MLS click stimuli (maximum stimulu...

| Summary: | The use of maximum length sequence (MLS) stimuli to elicit
an auditory brainstem response (ABR) has been limited, in
part, by the observation that these stimuli reduce ABR wave
amplitudes. This study recorded ABR waveforms from 14
normally hearing adults using MLS click stimuli (maximum
stimulus rate = 250 clicks per second) at stimulus levels of 70,
60, 50, 40, 30 and 20 dB nHL, with a vertical and then an ipsilateral
electrode montage. The vertical electrode montage
produced significantly larger (p ! 0.05) wave V amplitudes,
with no change in wave V latencies (p 1 0.05), at all stimulus
levels. This result suggests a vertical electrode montage
could be used to counter some of the loss in wave V amplitude
observed when using MLS stimuli. |
