People with schizophrenia who wave their arms around in wild motions and make kicking motions with their legs are experiencing:
a. catatonic rigidity.
b. catatonic posturing.
c. catatonic stupor.
d. catatonic excitement.
I'm not 100% certain, but I THINK your answer would be catatonic excitement. That's when someone in a catatonic state exhibits motor activity that doesn't really have a meaning behind it and generally does it regardless of attempts to stop them.
