RLS is a disorder diagnosed by the presence of four essential symptoms:
- An uncomfortable sensation usually located in the legs that are associated with an overwhelming urge to move.
- The experience of these sensations when the individual is immobile or at “rest.”
- When the individual moves, the symptoms improve.
- The symptoms are most prominent at night.
Due to the nature of these clinical symptoms, individuals with RLS often experience difficulties sleeping at night and functioning during the day.
