Do you know that there are two kinds of abnormal leg movement that affect sleep: Periodic Leg Movement (PLM) and Restless Leg Syndrome (RLS). PLM is when legs will twitch and jerk while the person is asleep. RLS is a creepy, itchy feeling that happens when a person is awake. RLS can progress to the point that it occurs during sleep. Both disrupt sleep by creating arousals that disrupt the natural rhythm of sleep or by making it difficult to get to sleep. Thus, the sleeper may awake feeling unrefreshed. Sometimes people may think they are awakening because of other reasons such as urge to urinate, however, it is can be the abnormal leg movement that causes the awakening.
