Abstract

Objectives: To evaluate sleep, mood and autonomic function objectively and electrophysiology subjectively in Chinese RLS (Restless legs syndrome, RLS) patients. Methods: A total of 15 RLS patients and 16 non-RLS controls were recruited from out-patient clinics of neurology department. Questionnaires(PSQI、ESS、HAMA、HAMD、COMPASS-31、SCOPA-AUT) were asked and electromyography (SSR、F-wave、H reflex) was conducted. Results: PSQI score was higher in RLS patients than controls. Mood and autonomic score didn't differ between two groups. In addition, F-wave latency, H-reflex latency, H/M amplitude ratio and SSR latency was similar between two groups. H-reflex amplitude and SSR amplitude didn't differ, neither. SSR amplitude (P=0.042) and H-reflex amplitude (P=0.047) was statically significant, but probably false positive. Conclusion: RLS symptom impacts sleep, especially during bedtime over mood and autonomic function. In the meantime, there is still a lack of electromyography biomarker to help diagnose RLS. More studies with bigger sample size are needed in the future. It is possible that small fiber dysfunction is not involved in the pathophysiology of RLS.
