Diagnostic criteria from the International RLS Study Group (IRLSSG) are as follows: [1]

  • An urge to move the legs usually but not always accompanied by or felt to be caused by uncomfortable and unpleasant sensations in the legs.
  • The urge to move the legs and any accompanying unpleasant sensations begin or worsen during periods of rest or inactivity such as lying down or sitting.
  • The urge to move the legs and any accompanying unpleasant sensations are paritally or totally relieved by movement, such as walking or stretching, at least as long as the activity continues.
  • The urge to move the legs and any accompanying unpleasant sensations during rest or inactivity only occur or are worse in the evening or night than during the day.
  • The occurrence of the preceding features are not soley accounted for as symptoms primary to another medical or behavioral condition such as myalgia, venous stasis, leg edema, arthritis, leg cramps, positional discomfort, or habitual foot tapping.
