Happy studying!!

neuro exam in a week and this just explained EMG better then any of the professors

[Draontail]

I am not a medical professional. I am a patient with a problem in her shoulder and I just had and EMG. Even I could follow this explanation. Great work!

[lalanto]

You're one of the best explainer I have witnessed, Doctor! You're making my med school bearable. For sure even a primary schooler can understand you!

Thank you, Doctor!! 🥰

I had right hip arthroscopic surgery FEB2021 - I experience spasms and various pains in my anterior thigh (sharp, burning, allusive itching, cold wash, tingling), with other groin, knee, inner thigh, outer-hip and buttock pains. I have finally gotten my pain management team to schedule an EMG/NCS. PM diagnosed me with meralgia parasthetica- however I have been pushing for the EMG for almost a year, now, due to muscle loss and functional loss. (I cannot fully extend through a step while walking without my leg buckling and so I walk with a cane). This information gives me some comfort knowing what I am going into and the science behind the method. I have had spinal nerve ablation, LFCN ablation, corticosteroid injections and I am scheduled for a steroid injection for my sacroiliac joint. They’re trying to find the pain source - but I truly feel it’s femoral nerve damage from the surgery. Thank you for this video - It’s been a hard road and I’m hoping for some answers with this study.

I have denervation in my right arm and triceps I had an emg and was trying to understand the results… u explained this better than my doctor. U are amazing! Thank you for the video

[Isabella-uwms]

I´m so happy this video exists. Nobody could really explain it to me in detail but now I understand! you really helped a future neurologist :)

[devkisalkar]

Wow! Thankyou.. currently studying for my Masters in Orthopaedics Physiotherapy exam. Started with studying EMG, came across your video and got hooked.

"This is the Joe Rogan experience" got me xd. Nice video, thanks.

[filmonhaile]

The sudden 'This is the Joe Rogan experience' killed me 😂

[kevinc]

Simple and clear, I'll be checking in every day. Have a good one doc.☺️

I am getting an EMG in a month due to my muscle spasms/ twitches. I have both fasciculations ans I think fibrillation. I can feel a buzzing/vibrating feeling in my muscles sometimes.

[laanaalove]

How are you versed in every aspect of medicine? I watch ur channel so much and I'm always amazed

[iamwagata]

This man is a genius! Great video indeed 💯

[johnathanabrams]

Fasciculations can occur outside of neurogenic disease .

During autonomic nervous system dysfunction mitochondrial biogenesis is impaired, acetylcholine leaks from the neuromuscular junction and sarcomere contractions occur.

I really wish you will reach and surpass million subscribers. In Shaa Allah!

[naturallawhealth]

This is great!! Easy to understand with a few laughs 🤣😁😊

[miradoc]

I'm a new subscriber here 🙋 i liked ur work and explanation 👏 thank you so much doc ❤️

Hi,

Let’s say a patient has BFS. A neurologist puts them under the EGM test. And connects the electrodes in the areas that the patient is experiencing twitches. During the EGM process, twitches happen obviously, at the patient is anxious and unlucky. How would the EGM result show the graphs during all three categories? Especially, in the first scenario where there is no contraction. Does EMG show some abnormal activity since the muscle was fasciculating during the test?

[compilationlou]

I did some research and in turns out fibrillations are due to muscular denervation, not necessarily myogenic diseases. The reason you get the fibrillation is because the denervated muscles are more sensitive than normal muscle. I guess you can make the argument that in certain inflammatory myopathies there are muscle fiber break down and mild denervation causing occasional fibrillations.

acetylcholinesterase is not attached to the nerve side, but muscle side. Muscle side also produces it. Therefore, destruction of the nerve will not results in a decrease of acetylcholinesterase
