As surgeons, we often send our patient for a Nerve Conduction Study or an EMG study as we need to know more about the problem that our patient has presented with. It would be good if we are able to interpret the findings, so that we can use the information to understand the problem better, and plan the management schedule.
This video discusses the basics of Nerve Conduction studies - Sensory and Motor, Needle Electromyographic Studies, Evoked Potentials, Intra-operative Nerve Studies and the interpretation and applications, and the use of these studies in the post-operative period to follow the growth of the nerve.

Thank u so much sir. Not only for surgeons,but also for physiologists like me,u ve made the concepts very simple,in a nutshell which made it easier for teaching my Postgraduates of MD Physiology. Thank u once again sir

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.

Sir why do we perform NCS after 10-12 days and EMG after 3-4 weeks..?? Is it related to pathophysiology of nerve?? If yes please tell sir.🙏🏻

Very helpful At 14:08 it says that difference in latency divided by time gives the MNCV. But latency is a measure of time, and there is no measure of DISTANCE in this formula.... hope it is not an error.

@bhavyaj96
@bhavyaj96 2 года назад
A doubt sir. How is proximal latency (in milli second) - distal latency ( in ms) divided by time giving a value in units of metre/second?

Sir is there any effect of underlying implant on recordings like in a case of fracture humerus with implant in situ

Can we fully recover from winged scapula If nerve is involved? ( Cause was back punch in an accident almost 5 years ago )
@GKHandSurgery

Depends on the type of injury to the nerve. Mild or severe.

If there is disease of spinal cord...and root is intact then we will get false negative result for root due to cord bad conduction... Is it ??

Very informative video. Sir, could you please suggest what could be the positions of recording electrode on cortex while stimulating lower limbs and where the reference and ground electrode should be placed for ssep
@GKHandSurgery
@GKHandSurgery 3 года назад
When the median nerve is stimulated for SSEP monitoring, the cathode should be placed over the Median nerve, 2 cm proximal to the wrist crease. The anode should be placed 2-3 cm distal to the cathode or on the dorsal surface of the wrist. Neutral or grounding electrode is placed on the palmar surface of the forearm or a band electrode around the forearm should be used as the ground electrode. The recording electrodes are placed on the scalp over the underlying sensory cortex using bipolar “scalp-to-scalp” electrode.

14:18 sir nerve conduction velocity equation is wrong It should be ncv = distance between proximal and distal points / ( proximal latency - distal latency)
