cogwheel rigidity 

Perhaps u should correct the title of this video. This seems like a resting tremor. Definitely not a "cogwheel rigidity"

Hey PA life. Please update this... making PAs look bad here. Obviously a resting tremor, not cogwheel rigidity.

Definitely not cogwheel rigidity. This is probably a parkinsonian tremor, but even then, the tremor seen in parkinson disease is classically a "pill-rolling" tremor.

thats a resting tremor

Thank you RU-vid for removing dislike count... this is not cogwheel rigidity. Harder to identify misinformation for students who are trying to learn.

Is it not Clonus?

it's a resting tremor. fix it for students

It is tremor, not rigidity

Resting tremor

' what happen to the right arm / hand shake shake... is that nervous system problem

That's pill roll tremor

This is misleading rigidity!!!

hes on a train? and one hand is bouncing, while the other hand is not effected.

Hypertonia is due to rigidity. When tremor is present, it adds cog wheel character to the already present rigidity. So the video title is right.
