In this video, Dr Mike explains how motor pathways travel from the brain and down the spinal cord to the muscle. He explains how reflexes work and what happens in upper motor neuron and lower motor neuron injuries.
Thank you very much doctor, you were able to explain an incomprehensible 2 hour lecture in 8 minutes completely understandable lecture, I think our professor needs to watch your videos too
Thank you so much! Neurology isn't my strongest subject and I find it quite overwhelming. You've just explained the concept of UMN and LMN lesions in such a simple way and I finally understand, woo! Thanks again. Take care
Thanks so much ! your 8 mins of teaching is better than my 2 hours of lecture in my prof. class. you help a lot for my studying in occupational therapy course
Thank you so much for this explanation. It helps me to understand spinal cord damage due to a tumor. I will be watching more to hopefully learn is my mobility will return. May God Bless you for your marvelous teachings!
Thank God I watched this video early otherwise I might be wasted many hrs by watching other RU-vid videos for understanding this concept thankyou doctor for explaining is easy understandble 🙏
Very well explained,I have spasticity in both legs,I had the ankle/foot test it was positive.My rheumatologist said upper neurons,clonus & spinal cord compression.I couldn't take it all in,thankyou for your explanation 🧠🦵🦶👍
i literally cannot thank you enough for how you explain things. i am currently in PA school and all of your videos have been helping me understand things instead of just memorizing things. i cannot express enough how thankful i am for your videos! i recommend them to everyone!
This video is amazing but one thing: perhaps moving the drawing of the leg to midline of the cerebrum to coincide with the homunculus would help with understanding. Amazing job!
I wonder if my cranial cervical instability (due to Ehlers Danlos, which is now fused) is what brought on Dystonia (episodic but generalized) for me...and would this qualify as upper motor neuron or spinal cord injury?
What's the best way to reverse this after a spinal cord injury.. what diet and herbs/exercise..? My injury level c7 c6 incomplete My spasms do pretty good after a good stretch. Any advice will be great 👍🏾
Sir, could you explain why antigravity muscles (flexors for the upper extremity and extensors for the LE) are more affected in (not completely paralytic) UMN lesions? I read it has to do with inhibitory pathways, but unfortunately I do not fully understand it!
I have a question regarding hypertonia and hyper-reflexia (5:00 of video). If someone has an UMN lesion, could the hypertonia/hyperreflexia also be clonis?
Dr Matt, so hyperreflexia with flaccid limbs? UMN & LMN with problems from disinhibition. Ie a patient with flaccid limbs will move the limbs with stimulation to just the hamstrings.
At the level of lesion it behaves as LMN and below the the level of Injusry is UMN. So you you will have to see which level and which muscles are getting involved and according to that LMN lesion will be flaccid and UMN lesion is spastic.
