Restless Legs Syndrome and Periodic Limb Movement Disorder
Restless Legs Syndrome (RLS) is characterized by experiencing unpleasant “creepy, crawly” sensations in the legs when sitting or lying still, especially at bedtime. The uncomfortable feelings occur most often in the calves and are temporarily relieved by stretching or moving the legs. RLS occurs in up to 15 percent of the population, and is not related to emotional or psychological disorders. The constant need to stretch or move the legs to stop the sensations often prevents a person with RLS from falling asleep and can result in restless nights.
Periodic Limb Movements Disorder (PLMD), characterized by involuntary movements during sleep, most often occurs in the legs. Periodic limb movements in sleep may disturb the person with limb movements or his or her bed partner. PLMD becomes more common with increasing age. RLS and PLMD can occur in the same person. Most people with RLS also have PLMD, but many people have PLMD without having RLS. |
