Questions Used to Ascertain Presence of Restless Legs Syndrome

1. Do you ever have an urge to move your legs that is difficult to resist? If YES, proceed to questions 2–8:

2. Will simply changing leg position by itself once without continuing to move usually relieve these feelings?

3. Is this urge to move usually accompanied by unpleasant sensations in the legs?

4. Are the unpleasant sensations due to leg cramping?

5. Does the urge to move or unpleasant sensations begin or worsen during periods of rest or inactivity such as lying or sitting?

6. Is the urge to move or the unpleasant sensations partially or totally relieved by movement, such as walking or stretching?

7. Does the urge to move or the unpleasant sensations only occur or get worse in the evening or night?
