cVEMP: An Introduction

[@ott2732]

You’re helping me so much with your videos!

[@InteracousticsTV]

Glad to hear they can be of use! ☺

[@monikalamanda3864]

This is a very great video to understand c-VEMP, thankyou so much

[@InteracousticsTV]

Thanks Monik, glad you enjoyed it :)

[@taimasalem2558]

I want to ask if functional head impulse device available in interacoustics and how much it cost???

[@MukeshKumar-py9sv]

What do you mean by recording window ? and what is the scale to know that patient is contacting muscle sufficiently (Video 25:50)?

[@ЕкатеринаСеливерстова-ч2ш]

You placed the reference electrodes on the SCM? Is that correct?

[@InteracousticsTV]

Thank you for your question. For cVEMP measurement the Interacoustics Eclipse system uses the RIGHT and LEFT reference electrode sites to measure both the EMG activity of the SCM, and the myogenic response triggered by the stimulus activiating the VCR. The active electrode is placed on the sternoclavicular joint, and is used for both the RIGHT and LEFT measurements.

@@InteracousticsTV Sorry to disagree. In electroneurodiagnostics the convention is the active electrode would be the place you want to record a response from, this test would be the LSCM + RSCM. The reference electrode would be an area near but less active than the active recording electrode, this test would the clavicular joint.

[@مريمالمطيري-م7ح]

What type of electrode used???

Hi! Ambu Neuroline 720: www.sanibelsupply.eu/ambur-neurolinetm-720-electrodes-25-pcs Best regards, Shane

[@bharathkadiriaudiologist8248]

Sir what is the normal amplitude ratio

[@InteracousticsTV]

Hi Bharath, I recommend reading section 6.2 in this paper: www.sciencedirect.com/science/article/pii/S2467981X19300095 Best regards, Shane

[@bharathkadiriaudiologist8248]

@@InteracousticsTV sir that is a asymmetric ratio up to 35 it's normal but I want a rectified amplitude muvolts like I will share you the screen

[@bharathkadiriaudiologist8248]

Please provide your what's app number I will share you my???
