Abstract

Despite the renewed interest in Sydenham's chorea (SC) in recent years, there were no valid and reliable scales to rate the several signs and symptoms of patients with SC and related disorders. The Universidade Federal de Minas Gerais (UFMG) Sydenham's Chorea Rating Scale (USCRS) was designed to provide a detailed quantitative description of the performance of activities of daily living, behavioral abnormalities, and motor function of subjects with SC. The scale comprises 27 items and each one is scored from 0 (no symptom or sign) to 4 (severe disability or finding). Data from 84 subjects, aged 4.9 to 33.6 years, support the interrater reliability and internal consistency of the scale. The USCRS is a promising instrument for rating the clinical features of SC as well as their functional impact in children and adults. © 2005 Movement Disorder Society
