The interesting report by Phillips et al1 on restless legs syndrome (RLS) calls for additional epidemiological data in patients from regions other than the United States.
My own experience spans a quarter of a century and relates to 3 study groups of patients: 1 rather large sample of over 2300 patients with musculoskeletal disorders and 2 separate groups of patients (n = 80 and n = 82) with RLS.
