ABSTRACT

INTRODUCTION Fidgety movements assessments is very sensitive predicting long-term outcome or cerebral palsy of preterm, disrupted cerebellar growth has been reported in these patients.

AIM To compare the predictive value of cerebellar ultrasound growth and fidgety movements assessments, for neurodevelopment outcome of very preterm at 18-24 months corrected age (CA).

SUBJECTS AND METHODS Prospective study of 88 infants cohort (<= 32 weeks gestation), transverse cerebellar diameter was obtained by ultrasound via mastoid fontanel, in a weekly basis, until 40 weeks CA. Fidgety movements were assessed at 3 months CA. Neurodevelopment outcome at 18-24 months CA was evaluated in 68 using Schedule of Growing Skills II Scale (SGS-II) and Amiel-Tison Neurologic Assessment (ATNA).

RESULTS At term age, cerebellar growth was under 3rd percentile in 11 (10.3%). Fidgety movements were normal in 42 (61.8%) and abnormal or absent in 7 (10.3%). At 18-24 months CA, 54 (79.4%) were normal by the SGS-II and in 6 (8.8%) ATNA classified as cerebral palsy. Cerebellar diameter under 3rd percentile at term was associated with abnormal motor outcome and normal fidgety movements correlated with normal neurodevelopment. CONCLUSION. Ultrasound cerebellar measurements and functional examinations (fidgety movements) have important complementary roles in predicting neurodevelopment of very preterm.
