What is Restless Legs Syndrome?

Restless legs syndrome is a sensori-motor (movement) disorder characterized by uncomfortable sensations in the legs, which are worse during periods of inactivity or rest or while sitting or lying down. There is often a positive family history of the disorder. Individuals affected with the disorder describe the sensations as pulling, drawing, crawling, wormy, boring, tingling, pins and needles, prickly, and sometimes painful sensations that are usually accompanied by an overwhelming urge to move the legs. Sudden muscle jerks may also occur. Movement provides temporary relief from the discomfort. In rare cases, the arms may also be affected. Symptoms may interfere with sleep onset (sleep onset insomnia). Research suggests that restless legs syndrome is related to periodic limb movement disorder (PLMD), another more common motor disorder which causes interrupted sleep. The symptoms often exhibit circadian rhythmicity in their peak occurrence during awakening hours.
