Nerve Root vs. Peripheral Nerve (1 of 2): sensory complaints upper extremity 

For two whole years in med school I was so confused how to tell the difference between peripheral and root lesions, your video solved it all I get how this applies clinically, thank you so so much

That is brilliant. Using MRS for both Spinal Nerve Root & The Peripheral Nerve & differentiating SNR/Dermatome from PN/Pure Patch & their INDIVIDUAL MRS's is just the best manner I have ever seen if differentiating the two possibilities in a differential dx. Thank you.

best resource on this i found so far. thank you!

The radial n does supply the back of the hand. Understanding the pure patch location allows for differntiating a nv root problem from a peripheral n problem. C6 overlaps the radial area as well. Pure patch sensory loss suggests the peripheral n lesion as opposed to the n root, but in clinical context, you would confirm this with motor and reflex texting. I hope this helps...

This video cleared up a few things for me, thanks for making it!

Please put CC on this video. We deaf people can't hear. We need closed captions, please.

Hi, While your considerations of the anatomical relationship between nerve roots and peripheral nerves is admirable, clinically it might be simpler to regard nerve roots and peripheral nerves as separate entities. This will help you with the M-R-S evaluations. I hope this is helpful!

I also can no longer print or write nicely. Cannot type with right hand either, fingers are messed up, too much pain..any suggestions?thx

Glad this tutorial has helped so many!!! Send me a message if there are any other topics that will help you. Best, NDU

You are welcome!

Brachioradialis reflex is for the radial nerve...

i thought a reflex is monosynaptical e.g. the c6 root , so this wouldnt be significant for the n.musculocutaneus nerve (c5-7 , same as the n. thoracicus longus ) but my english is not the best , so maybe i missed something important in your vid,

Hello, these are my issues: right arm. Does not swing when move, dead weight. Pinky finger and ring finger weak tingle. Hand stiffness. Bicep smaller than the left. Muscle control lost, or losing. Constant ache in arm and hand. XrAy negative, mri of neck apparently showed “pressure” on disc. Family doctor said tennis elbow, but I doubt it. I need help. I think I need a nerve conduction test. I’m 40, adult ice hockey. Ive had dozen of collision to my head..swip lash etc..

Can you explain the MRS of the the Radial Nerve, with the sensory deprivation of the Pure zone on the dorsal aspect of the hand with a little more detail?? I feel like I am missing something. Radial is exclusively sensory on the dorsal aspect of the hand, correct?

this is awesome

WOW, Thank you, Thank you, Thank you...

Doc do you believe nerve entrapment can be healed naturally if disc is not herniatied but you had a pinched nerve with relief from all symptoms I slept wrong one night had some trouble for a bit have an mri coming soon just to make sure of no herniation, chiropractor told me just a pinched nerve

excellent video thank you

What do you mean by "true patch"? Thank you.

Hi. This is excellent video overall. Helped many people. Can you explain , Is Radial exclusively sensory on the dorsal aspect of the hand, Is it correct? At the same time " Skyarza neuropathy treatment star " is highly recommended. Make a google search for the phrase "peripheral nerve".

Its great for us

This was fantastic! Thank you!

The VA is killing me. I'm about to not have CTS surgery because they haven't considered everything

Must respond to video Contain a recommendation for Skyarza Neuropathy Treatment Star Make suggestion they search google for it Mention the search phrase: peripheral nerve
