My husb left foot swings up and down every night as he tries to get to sleep. Some times it is the whole foot ankle that rocks up and down or side to side and sometimes it is just the toes. Is this spasticity? Is this clonus? He can literally do this for an hour or more. I am not trying to stop this but rather want to know if others have experienced or noticed this? It is similar to restless leg yet more repetitive.
