In evoked potential testing, there are various ways to measure residual noise. But which one should you use? The fully objective and perhaps easiest method is to use the automated residual noise calc…
How much masking should we use in this ABR case example? We tested a 7-month old baby with a bilateral conductive hearing loss. We wanted to check whether we need to mask or not. The not-masked heari…
The Dix Hallpike test is the most well known positioning test as it is used to diagnose posterior canal BPPV, the most common variant of BPPV. There are other positioning tests and diagnostic movemen…
No, the Eclipse does not have a notch (i.e. band-stop) filter. A challenge of these tools is that the line noise is only selectively eliminated with very steep slopes (sharp cut-offs) on either side…
It’s difficult to answer the question about how close you can get to threshold using eABR. eABR testing allows us to record a threshold on the equipment, and this is then used to set the T level on t…
Question I read this new article, which is pretty positive about the Eclipse ASSR (Sininger et al 2018). But it raised a question about clinical practice which is not clear to me. Is it necessary to…
For caloric testing, I am just thinking if we can do cold or warm water alone, why we need to do bithermal beside the benefit of better averaging. Answer: Well your question already encapsulates one…
This video demontrates a live recording of the ocular VEMP, and the identification of the biphasic response, and the marking of the waveform. Transcript Darren Whelan: Now that we have our patient pr…
