HI. Thanks for your informative lecture .I have an inquiry regarding your OVEMP norms. Why your Ovemp has very late latency ? should be expect N1around 10 ms and P1 around 16 ms. Thanks
@e3MedAcousticsIncАй бұрын
I think if you invert the polarity of the oVEMP waveform you will see the latencies you are expecting.

Oh, I’ll add that I have balance issues (sometimes hold walls to stay upright (not fall) - more rare .. and doing vestibular exercises with the sensory integration therapist, like sitting on a yoga ball moving back and forward and side to side (not holding the ball and having to balance), then told to go sit on the couch 🛋️- in about 20 seconds I suddenly feel like I’m falling and there’s a spinning sensation and it lasts about a minute? - I am also autistic, they believe I have autistic catatonia - meaning all auto issues become severe and then u can lose all abilities (have done 2x) .. and that includes a severe heightening of my sensory sensitivities and I also can’t manage conversations with people for very long .. as il start to shut down. - that’s some of my annoyingly large history that possibly relates. Thank you 🙏

The ocular VEMP is hard to measure on some people. An absent oVEMP does indicate a vestibular problem. If you also have systems, more testing is needed. VNG and vHIT are two test procedures that can be done.
@e3MedAcousticsInc Жыл бұрын
@@beckacheckaenterprises7294 The vestibular exercise will help this patient. She has probably had the VNG and vHIT tests. But let's respond like this: Sorry to hear about your vestibular difficulties. The vestibular exercises will continue to help. If you have not already had them, we definitely feel that adding the VNG and vHIT tests will help to pin down the cause of your vestibular symptoms.

Did Greg Sr take any classes at Tech from Marshall Leach or Gene Patronis? If they were still around, they'd rap his knuckles! All kidding aside, when it comes to ABR rigs, there’s the Vivosonic Integrity… And then there’s everything else (unless you test in a Faraday cage). Yes, they had 802.15 (Bluetooth) teething problems, as almost everybody did (except Apple) at the time the stack came out; but by 2012 when I first tried one at a conference, they had it all sorted out, as at the time all of the other ABR rigs had long leads to the ADC’s. →The MRI RFI/EMI issue is something I’ve never run into-Good catch! [With regard to the Anniston AM radio station, a few carefully-placed .01 & .001µF bypass caps would have fixed the problem. Although the broadcast station (or in my case in high school, ham radio station WB2UBQ) is not responsible for neighborhood RFI/EMI problems, if you ask the Chief Engineer nicely, he’ll help you hunt down and swat the problems.] Also, the biggest issue when you buy a premade sound room is the floor you put it on: That 5,700 lb 6x6 *single wall* box will give you a floor loading of about 160 lbs/ft², and if you’re not on a concrete pad, you can run into Serious Problems, especially in multi-story buildings. As a rule-of-thumb, you need 200 lbs/ft² floor loading capacity to run a forklift on it; so if the floor can’t handle that, call in a Structural Engineer as it may be a close call. [Don’t ask me how I learned about THAT one!]

I do have two questions. 1) If I want to use a horizontal montage do I place the cz electrode on the mastoid, earlobe or where? 2) I recently attempted to test a patient and all of my electrodes indicated greater than 25 kohms. I have never had that happen. Any ideas? Thanks and great presentations. I have learned a ton from them and will continue to do so.

Kelly, For a horizontal montage, I put the “CZ electrode” (-) in the test ear and other electrode (+) in the other ear, with the ground on the forehead. Use one-channel mode. Get better impedance by both abrading the ear canal with new NuPrep and cleaning with alcohol.

Hi greg.., in cases of sensory hearing loss.. how would it affect the wave v latency intensity plot… thanks
@e3MedAcousticsInc2 жыл бұрын
In the case of sensorineural hearing loss, the latency-intensity plot will not run parallel to the normal range. Instead, the wave 5 latency may be in the normal area (or close to it) at high intensities (80-90 dB) but raises quickly out of the norm area and continues to raise, more and more, outside and above the normal area, as you run curves at the lower intensities. If you have a good repeatable wave 5 ABR curve at 90 dB, continue to run curves, and lower the intensity by 10 dB each time, until you can no longer get a decent and repeatable wave 5. Hope that helps.

@e3MedAcousticsInc3 жыл бұрын
Reproducibility is repeatability. It means always averaging at least two waveforms. They are said to repeat if they have the same absolute and inter-wave latencies and the same basic morphology. A true AEP response can only be said to exist when it is repeatable. Hope this helps.

ASSR is a very low level response. It is overwhelmed by the EEG if the patient is not sedated. Even with ABR, it is best for the pediatric patients to be sleeping or sedated. This is especially true when doing tone bursts.

@e3MedAcousticsInc3 жыл бұрын
To estimate thresholds in infants, you can use either Tone Burst ABR, Narrowband CHIRP ABR, or ASSR. The patient will need to to sedated or sleeping to do ASSR. Most pediatric audiologists would opt for tone burst (or Chirp) ABR done at a time that the baby is likely to be sleeping. Hope that helps.

A conductive hearing loss delays Wave V due the resistance it imposes to the transmission of sound energy through the middle ear. It is best to look at the Wave V latency-intensity plot to identify a conductive loss. The plot will run above and parallel to the normal area. Hope that helps.

@e3MedAcousticsInc4 жыл бұрын
Yes, wave five can be pushed to the right of normal (delayed) with a conductive loss. However, the best way to determine a conductive loss is with a latency-intensity plot of wave five. It will be quite different from a sensory loss plot. (It will run parallel to the normal range, but separated from it.) Also use bone conducted ABR, and note the air-bone gap as well as tympanometry.

1000 Hz typanometry is used on babies from birth through about 6 months to avoid a false negative due to ear canal compliance. If a valid type B Tymp is found in both ears, a conductive hearing loss is likely. It will be more pronounced in the low frequencies, and could be up to around 40 dB at 500 Hz, decreasing at 1,000 Hz and higher. Patient should be referred to an petiatric ENT facility.
