title: [The initial testing and the discrimination property of the UFMG Sydenham's Chorea Rating Scale (USCRS)].
abstract: Recently we developed and validated the Universidade Federal de Minas Gerais (UFMG) Sydenham's chorea Rating Scale (USCRS) to systematically assess SC patients. In this study, we assessed 97 children and adults with SC (mean age +/- SD, 15.5 +/- 5.9; male/female, 31/66) seen at the Movement Disorders Clinic at UFMG employing the USCRS. The patients were divided into 4 groups according to their clinical status: acute (n=19), recurrent (n=17), persistent (n=19) and remission (n=42). The mean +/- SEM USCRS scores for each group were: 47.7 +/- 4.7 for acute group, 29.5 +/- 2.6 for recurrent group, 17.6 +/- 3.1 for persistent group and 1.1 +/- 0.2 for remission group. All pair comparisons were statistically significant (p<0.05). Our results indicate that the USRSC can reasonably discriminate groups of SC patients in different clinical stages of the disease.
