Abstract
AIMS: To pilot the practicality of administering the Prechtl General Movements Assessment of infants (GMA) in the Neonatal Intensive Care Unit (NICU) setting and at home to infants at risk for developing cerebral palsy (CP). Additional aims included assessing inter-rater reliability and comparing GMA predictions to AIMS motor assessment at 12 months. METHODS: 12 "at risk" infants were recruited by convenience sample. Video recordings were obtained in the NICU and provided by parents after discharge. These recordings were analyzed by two trained examiners to assess infants in the writhing and fidgety movement periods (birth to 16 weeks). Infants were assessed at 12 months corrected age using the Alberta Infant Motor Scale (AIMS) with scores lower than 5th centile considered a motor delay. RESULTS: 33 of 42 videos (79%) were of sufficient quality to permit interpretation and there was 97% inter-examiner subcategory agreement and 100% overall developmental trajectory (abnormal/normal) agreement. The GMA demonstrated a sensitivity of 60% and a specificity of 100% in predicting AIMS score (age appropriate or delayed). CONCLUSIONS: Clinical feasibility of GMA obtained in the NICU was demonstrated however feasibility of parents providing video samples after discharge was not demonstrated, indicating a need for a parent-friendly method.
