25. Interpreting neurophysiology (EMG & NCS) 

This is an amazing lecture! I am a medical student on an EMG elective and this explained everything so clearly with wonderful examples. Thank you so much!

For organized and concised lecture yet covers all the necessary basic info. Thanks a lot.

Very educational video for those learning EMG/NCS. Thank you!

Excellent job for both medical students and non-neurologist. Thank you.

Very good presentation. I have thoroughly enjoy the video.

Fantastic presentation with clearly explained concepts

thank you. It helps a lot

Excellent presentation thank you very much. Going for my test in June I have to wait till June it’s March and my left side is just bugging the crap out of me and I’m down to my foot getting better my right side now mostly on the left it comes and goes but when it comes it’s not comfy it’s just a persistent weird numbness tingling nonstop sensation and even affects the back of my head I get the weirdest sensation in my brain specially on the right side where it’s like my brain is falling asleep

good lecture. Thank you.

Outstanding presentation Dr.Crump!

To me This Is Grate. Thank you very very much....

best video I found to explain EMG

Great lecture.. thank you 🌷

Good explanation of EMG well done u r examples of EMG case report

Thanks a lot for posting that video. Is there some lecture of surface electromyography?

Very comprehensive . thank you

Just perfect..Thanks

Very nice ...Thanks

fantastic!! Thank you!!

When comparing results from nerve conduction test between left and right cut. antebrachii med should a 0.6 ms delay considered to be difference? Taking into account that we know from physical exam the site with delayed latency has no feeling sensation?

you have summarized all the needed information

"Huh, I guess you weren't lying when you said your hand was numb."

It's the most painful and horrifying ordeal you will ever go through.

Excellent video, but when you were talking about F reflex, you said it is constant in latency. I think that the F reflex is not consistent in latency but the A wave reflex it is, which is the only way to differentiate both.

good video

Nice, continue

Good, thanks How can I localize ulnar nerve lesion at elbow, in cubital tunnel, behind med. Epicondyle, etc ?

How to straighten a curvy base, please? I have a green and a red electrode I place on the patient along with a concentric needle

My doctor wrote down a "13+" for upper and lower body. Is this normal??

Hi All, If a patient has benign fasciculations and during the EMG procedure, they experience muscle twitching etc in the area that is monitored by the electrode, do the EMG results show abnormality? How are they any different than someone with a condition such as ALS, or MS?

Had a emg done on right arm shoulder and neck . Found damage in shoulder . Have torn rotator cuff so this pushes back surgery 2-3 months need to strengthen shoulder and heal nerve before surgery. Strange thing is I have no real pain just limiting motion and strength also a lot of grinding in shoulder raising arm. Oh hated needle portion of emg !

💎💎💎👍👍👍

Ref books please

Ncs test is easy...... Its not that bad...

algorithm check 21:42

you cant get a "poly-phase reading from a single-phase DC circuit. Idk what the hell you think your talking about, but there is no poly-phase demonstrated here

Doctor please help me i did NCV test on both hands, one was fine before test but after the test it got way worse, they used 50 mili amps on me and it was so painful and my hand jumped alot.. Is there a chance ncv is harmful?

I don't really understand why it was problematic for that last gentleman to have sensory issues even though the NCS showed no amplitude reduction on the sensory study. Measuring the sensory conduction from the distal hand/finger to the wrist ought to be normal if the problem is located in the elbow, no? What am I missing?
