[Assessment of general movements at routine medical examination of one-month-old infants].
On routine medical examination of one-month-old infants, general movements (GMs) were video-recorded for about 5 minutes of 252 infants born at Kyoto City Hospital or other hospitals, including the infants discharged from the NICU. Their ages ranged from 39 postmenstrual to 8 post-term weeks. One of the experimenters assessed 181 infants among 252 available for assessment of their GMs twice at intervals of more than one month without being informed about their clinical histories. The subjects included 19 low-birthweight infants, and their average age was 3.5 post-term weeks. The assessment was carried out in comparison to the "gold standard" GMs depicted in a demonstration video produced by the GMs Trust. The Kappa value for intra-observer concordance was 0.85. Twenty (11.0%) out of the 181 infants were judged abnormal because of their poor repertoire of GMs in both the first and second assessment. Neither cramped synchronized GMs nor chaotic ones were observed. Meanwhile, 155 (85.6%) out of the 181 infants were found to be normal. The incidence of abnormal GMs was significantly higher among infants with history of asphyxia and/or respiratory distress than among low-risk infants. There of the experimenters independently assessed GMs of 50 infants among 181 which had been video-recorded between June and September 1998. The inter-observer concordance was higher among the low-birth weight infants than among full-term ones. In conclusion, qualitative assessment of GMs by an experienced observer at routine medical examination of one-month old infants is a useful method for the follow-up of high-risk infants.
