Thank you so so much!! especially for the last part. I literally searched the whole internet trying to figure out why patients will be in a flexed position. A life saver!!!!

Just a thought, why doesnt the same thing occur with rigidity? Is the agonist and antagonist affected unequally then?

Role of gamma motor neurone in development of spasticity is not explained in this video. Other wise the video has good information for students. Thanks for your contribution.

There are some debate on wether spasticity is "just" the change of balance between inhibitory and exitatory stimulus. It doesn't really explain the different types og hypertonia - rigidity or spasticity. Why is it, that rigidity does not show increased reflexactivty

Great. Why does the spasticity ''loose up'' at the end of motion in contrast to rigidity?

Are you referring to 'clasp knife' rigidity, where resistance suddenly 'gives' when enough force is applied? This is caused by Golgi tendon organs, which detect high levels of tension in tendons. They are part of a protective reflex (ever involuntarily dropped a weight that is too heavy for you?). Golgis are connected to inhibitory interneurones in the cord which inhibit motor neurones and cause the give. Hope that helps

I think CST neurons stimulate the inhibitory interneuron that connects to the alpha motor neuron (in blue).... Thereby inhibiting/controlling muscle contraction.

in the UE the flexors are stronger and win out over the extensors. this isn’t very scientific. how would you then explain decerebrate? really need to back up your thoughts with some science references, otherwise this really is just conjecture.
