Carpal Tunnel Syndrome - Part 2 Sensory Nerve Conduction Study
Просмотров 2,8 тыс.Месяц назад
This video is part of a short series of videos intended aimed at patients and healthcare workers to give a simplified explanation of Carpal Tunnel Syndrome and how it can be assessed using Nerve Conduction Studies. This video demonstrates a simple sensory nerve conduction study of the median and ulnar nerves.
Needle EMG demonstration
Просмотров 32 тыс.2 года назад
This video shows a simple Electromyography (EMG) demonstration, sampling from the right extensor digitorum muscle group. This demonstration shows how a needle EMG recording can be made. Importantly, in an actual diagnostic clinical setting, the Neurologist performing the EMG would be holding the EMG needle and adjusting the position of the EMG needle throughout the study. In this example, the N...
Motor Nerve Conduction Study

This video shows a simple motor nerve conduction study (MNCS) of the right median nerve. This study is perhaps the most commonly performed motor nerve conduction study and would be performed in most upper limb neurophysiological examinations.

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.
Thanks for your questions. No, it is not usual to experience any ongoing symptoms following a NCS study and it would therefore be important to advise your treating doctor about this. The NCS part of your examination cannot cause nerve damage as the electrical signals used are of type that are specifically safe for this type of testing and it is not possible for an examiner to exceed any safe limits. Needle EMG studies are not performed on the nerves, but are performed on muscles supplied by the nerves, so there should be no risk of injury to the nerve from the needle. Because a needle is used to sample from muscle, this can cause temporary local muscle tenderness and bruising in some people, in the same way as a blood test or injection can. I hope this helps.

Why it is done can anyone explain?
EMG reveals the electrical charactoristics of muscle, and the innervation of a muscle. This is a useful test for examination for muscular disease, peripheral nerve dysfunction and nerve-root dysfunction. EMG is always performed in combination with NCS. These studies are performed for the diagnosis of neuromuscular disorders.
Depends greatly on the reason why nerve signals are absent. Many reasons as to why.
If nerves are absent then what? … what next
I have to go this Monday for Upper emg test. Scared to death.
How did it go? I have one tomorrow...
I just did it. It wa very simple. Less than a pinch
How deep do the needles go
Depends on the muscle being examined, how large it is, and how deep it is from the surface of the skin. What is important to note, is that the recording surface of the needle electrode is in the very tip of the needle, so the entire needle does not need to be inserted into the muscle to perform the study.
I’m doing that tomorrow. Kinda nervous but we shall see
It wasn't that bad right ?
Was it painful ?
Nice content brother 😊 keep it up ❤️
