Neurophysiology of how muscles recruit

[@dersma1]

Thanks a lot Dr. Simon.
It's a nice video. I am a beginner in learning EMG. Is it actually possible to notice only from hearing, how many MUPs are recruited?
If yes, how to practice my ears to get it?
Thanks. I appreciate your effort.

Thanks! Its difficult to do past 6 or 7 MUPs because the Interference Pattern becomes too full to distinguish between them. However, you can certainly train your ears with practice to pick out the repeating units going at higher than expected rates. In the next video (axonal loss and regeneration which I hope to publish next week) there will be an example of this, as well as at the end of the Neurophysiology for Neurologists with the EMG from a Myasthenic muscle. There are some dedicated methodologies to estimate motor unit numbers using MUNE / MUNIX. Good luck and nothing beats experience - so keep at it! Best wishes, Simon

Sir ... Pls do a video on selection of muscles for emg in case of radiculopathy

Dr Simon I have a query.

[@apurvasharma4367]

please make a video on raster mode, mup analysis

Hi Apurva, I made one already called Quantitative EMG demo using Keypoint.Net. Bw Simon
