Restless Legs Syndrome and Periodic Limb Movement Disorder

Restless Legs Syndrome (RLS), also known as Willis-Ekbom Disease, is a neurologic sensorimotor disorder characterized by an overwhelming urge to move the legs when they are at rest. This urge is usually, but not always, accompanied by unpleasant sensations.

It is less common but possible to have RLS symptoms in the arms, face, torso, and genital region. RLS symptoms occur during inactivity and are temporarily relieved by movement or pressure. Symptoms of RLS are most severe in the evening and nighttime hours and can profoundly disrupt a patient's sleep and daily life.
