ABSTRACT
BACKGROUND AND

PURPOSE:

Few studies have attempted to develop clinical predictors for cervical dystonia (CD) aiming at progression of the dystonic movement.

METHOD:

We retrospectively evaluated 73 patients with primary CD who underwent treatment with Botulinum toxin type-A (BTX-A). The patients were assembled in two groups according to the spread of dystonia during follow-up spreading and non-spreading CD. We performed a binary logistic regression model using spreading of cervical dystonia as dependent variable aiming to find covariates which increase the risk of spreading.

RESULTS:

Our logistic regression model found the following covariates and their respective risk ratios time of disease >18.5 months=2.4, retrocollis=1.9, anterocollis=1.8, head tremor=1.6.

CONCLUSION:

Time of disease >18.5 months, retrocollis, anterocollis and head tremor may predict spreading of dystonic movement to other regions of the body in CD patients.
RESUMO

INTRODUÇÃO:

Poucos estudos avaliam preditores clínicos de progressão dos movimentos distônicos, para além da região cervical, em pacientes com distonia cervical (DC) primária.

MÉTODO:

Avaliamos, retrospectivamente, 73 pacientes com DC primária, que tinham sido submetidos ao tratamento com a toxina botulínica tipo A (BTX-A). Estes pacientes foram divididos em dois grupos de acordo com a progressão ou não da DC para outras áreas do corpo. Aplicamos um modelo de regressão logística binária usando a progressão da distonia como variável dependente com o objetivo de identificar co-variáveis que aumentassem o risco de progressão.

RESULTADOS:

O modelo de regressão logístico identificou as seguintes co-variáveis como preditoras de progressão e seus respectivos índices de risco tempo de doença >18,5 meses=2,4, retrocolis=1,9, anterocolis=1,8, tremor cefálico=1,6.

CONCLUSÃO:

Tempo de doença >18,5 meses, retrocolis, anterocolis, e tremor cefálico podem predizer a progressão do movimento distônico para outras regiões do corpo em pacientes com DC primária.
