ABSTRACT

The predictive validity of the Movement Assessment of Infants (MAI) for the detection of cerebral palsy was analyzed in 89 Brazilian infants, born with gestational age < or = 32 weeks and weight < or = 1500 g. The infants were assessed with the MAI at 4 and 8 months, corrected ages, and were submitted to a neurological evaluation between the ages 2 and 7 years old. Estimates of sensibility (0.61 - 1.0), specificity (0.79 - 0.95), positive predictive value (0.48 - 0.73) and negative predictive value (0.79 - 1.0) were calculated at 4 and 8 months, for risk points > or = 13 and > or = 10. The best predictive values were obtained at 8 months, with a cut off > or = 13 risk points. A less restrictive criteria (> or = 10 points) might be useful for the prediction of motor coordination problems at school age.

ABSTRACT

A validade preditiva da Avaliação do Movimento do Bebê (Movement Assessment of Infants - MAI), para detecção precoce de paralisia cerebral, foi analisada em 89 crianças brasileiras nascidas com idade gestacional < 32 semanas e peso < 1500g. O MAI foi aplicado aos 4 e 8 meses de idade corrigida e as crianças foram submetidas a avaliação neurológica entre 2 e 7 anos de idade. Foram calculadas estimativas de sensibilidade (0,61 a 1,0), especificidade (0,79 a 0,95), valor de predição positiva (0,48 a 0,73) e valor de predição negativa (0,79 a 1,0), aos 4 e 8 meses, para escores > 13 e > 10 pontos de risco. Os melhores índices preditivos foram obtidos aos 8 meses e para o ponto de corte > 13 pontos de risco. Um critério menos restritivo (> 10 pontos) pode ser útil para predição de transtornos da coordenação motora, na idade escolar.
