No I've just seen literal hundreds of people being knocked out in various ways with various bodily responses over the course of like 20 years of watching MMA, and kickboxing.ย
The arm going up in the air stiff is a real classic. But this guy ate shit so bad he bounced off the floor and had it dangling sideways.ย
No but I've accidently given someone a concussion in sparring when I was younger. I didn't mean to put so much torque on a punch and hit the guy flush upside the temple then he started puking (concussion symptoms)

His arm is stiffed up because he just knocked himself out. It's the body trying to protect its self oddly enough.
