Restless Legs Syndrome (RLS)

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.
