Structured interviews and 'ancillary' restless legs syndrome.

摘要

From the first description by Sir Thomas Willis more than three centuries ago, several definitions of restless legs syndrome (RLS) or Willis-Ekbom disease (WED) were proposed. Common to all of them is the urge or need to move one's legs. Clinicians and researchers seem to agree that the urge to move the legs is central to the diagnosis, albeit a clinical one. Additionally, part of the diagnosis is the effect of rest on the urge to move, the relief that comes with the movement and the circadian aspect. Over the past two decades since the four diagnostic criteria were first published [1] and then revised [2], the awareness to accurately diagnose these entities has increased [3].
