Long duration, large amplitude, polyphasic MUAP with reduced recruitment. Spontaneous activity: fibrillation. This is suggestive for neuropathic lesion.

I am a recent graduate specialising in clinical neurophysiology - I was wondering if you also perform EEG and Evoked Potential monitoring as well? Or even Intra-operative nerve monitoring? - Your videos are very nicely refined and comprehensive!

Hello sir. Thanks for sharing. I had an EMG done roughly 3 weeks ago to investigate muscle twitching in my right arm. ( not sure if that was recommended ). The emg was uncomfortable. I jumped at one point during the exam during the NVC part. The examiner apologised. It was over my ulnar nerve. I was told my EMG was normal. Apart from a mild ulnar neuropathy ( velocity 40) I was unaware nor did I have symptoms of neuropathy prior to the exam ever . Now 3 weeks later and i am still having excruciating burning in my palm 5th and 4th digit and shocky feelings in my arm after the EMG, all of which is new to me. Is this normal? Can the emg cause nerve damage ? If so how can I find out? I was told by a colleague that during the needle portion no needles was placed near my ulnar or elbow region. Can the volts during NVC cause nerve damage or irritation that lasts this long ? Are EMG standardised so that the examiner cannot exceed unsafe voltage? And is any of this temporary from your experience? Thank you kindly for any input you may have.

Normally they are huge when compared to other potentials... Just look at the settings in the EMG Window in the video...

Thanks, but what about post-exercise RNS with this muscle?
@leidenclinicalneurophysiology
@leidenclinicalneurophysiology 10 ай бұрын
Hi, I usually don't do post-exercise RNS, but it is a matter of taste. It could lead to a slight increase in diagnostic yield, but I prefer to use my time to investigate multiple muscles, which also increases diagnostic yield.

​@@leidenclinicalneurophysiology Thanks for all your help. I am used to Caldwell and recently started using Natus with synergy which is a downgrade for me. Can you make a video or go over the settings that you are using including the voltage per division and duration per division for both spontaneous and volitional activities. Thanks and much appreciated

fibrillation potentials are regular firing
@leidenclinicalneurophysiology
@leidenclinicalneurophysiology 11 ай бұрын
Hi Simone, although individual fibrillation potentials can indeed fire at a semiregular rate, their abundance, the fact that they are usually intermingled with positive sharp waves and fact that they can be elicited by needle movements all result in a rather irregular sounding signal, which is very different from the sound caused by the regular firing of MUPs at a rate of 5 to 30 Hz.
