While RLS movements are a voluntary response to unpleasant sensations in the limbs whilst awake, the movements of PLMD are involuntary and felt most when the sufferer is asleep.
PLMD sufferers are generally unaware of their limb movements or the resultant "microarousals" (very brief awakenings) that lead to excessive daytime sleepiness the morning after.
As sufferers of PLMD are unaware of their limb movements whilst asleep, it is necessary to have a sleep study.
