title: Predictive value of neonatal neurological tests for developmental outcome of preterm infants.
abstract: BACKGROUND
  There is a need to identify, as early as possible, infants who are at risk for long-term neurological morbidity.
  
  
  METHODS
  To predict neurodevelopment outcome of preterm infants <30 weeks' gestation in a population of 100 infants, we used several neonatal and neurobehavioral tests, including cranial ultrasonography, the Prechtl neurological test, quality of spontaneous general movements, and quality of sleep-wake organization.
  
  
  RESULTS
  The Prechtl test at corrected term age and findings on cranial sonograms both had high specificity, but the Prechtl test had better overall positive predictive power for normal neurological and developmental outcomes at 2 years' corrected age. Developmental changes in sleep and the amount of indeterminate sleep did not correlate with outcome. Scoring general movement quality did not predict outcome and did not augment the positive predictive power of the Prechtl test.
  
  
  CONCLUSIONS
  The Prechtl test at corrected term age (independent of the other tests) is the best positive predictor of normal neurological outcome and Bayley test results at 2 years' corrected age.
