    I have been an internal med doc for over 30 years and a lifelong learner. NO ONE has ever explained this as well as you have. Thank you!

    Amigo... you rank very highly on my respect and admiration list, because you've demystified all that I have been struggling to memorise for the past 3 weeks in a 9:26 minutes tutorial. You may not have been told this before but you are good at teaching. ;)

    Thank you for making UMN/LMN into a very simple concept to understand. Your explanation is very organized and easy to follow. Took me five other videos to get to the one that makes most sense for me :)! THANK YOU.

    Regarding hypertonia, think of a lesion to the upper motor neuron as if there is no descending input (inhibition) from the upper motor neuron. Therefore the lower motor neuron is disinhibited and is free to become very active, leading to hypertonia

    • @DirtyMedicine
      @DirtyMedicine  6 лет назад +2

      honestly, it's just that most professors are NOT good at teaching. Their schools/institutions force them to teach as part of their agreed-upon contract. Academics are typically not that good at articulating/conveying information. They are too smart for their own good

    At age 78 I must be dead! My toes do not go up or down when lightly stroked! I am using the ability to climb even two steps hands free. I exercised all my life. I can go up the stairs but I have to hang on to the banister rails and pull my self up 15 steps. And for all the knee exercises and yoga I did, I don't know what happened to my beautiful knees and legs! I was always diligent about my diet also. I did massage for 33 years and now my hands and fingers are numb, but not my feet.

    Thank you! In which diseases you see the upper motor neuron syndrome? I read it is a cause of spinal cord injury, cerebral palsy, multiple sclerosis, multiple system atrophy, amyotrophic lateral sclerosis and acquired brain injury included stroke. Is that true? And does everybody with this diseases have naturally the upper motor neuron syndrome?
