Abstract

Abstract:Objectives: To validate the application of CH-RLSq (Cambridge-Hopkins questionnaire for restless legs syndrome) in the diagnosis of Chinese RLS (restless legs syndrome) patients.Methods:Twenty-six RLS and 21 controls were enrolled in this study. RLS patients, "mimics" and healthy people were recruited from Out-patient Clinics of Department of Neurology and completed the CH-RLSq. Clinical data of RLS were also collected. The agreement of clinical RLS diagnosis with CH-RLSq diagnosis was assessed by kappa and Mcnemar tests.Results:CH-RLSq-based diagnosis was consistent with clinical diagnosis (kappa=0.745,McNemar test:P=0.216). The clinical characteristics of these RLS patients included female preference, high family history, and various concomitant diseases. Conclusion:CH-RLSq is a good screening questionnaire for diagnosing RLS in Chinese patients.
