ABSTRACT
Objective: To assess the association between the General Movement Assessment (GMA) findings, including Motor Optimality Scores-Revised (MOS-R) at 16 weeks, and neuromotor outcome assessed by the Amiel-Tison Neurological Assessment at 9 months of corrected age and the Developmental Assessment Scales for Indian Infants (DASII) at 1 year of corrected age in preterm ≤32 weeks. Study design: Serial GMA videos of infants born preterm ≤32 weeks were recorded on day 7, 35 weeks of postmenstrual age, 40 weeks of postmenstrual age, and 16 weeks of corrected age. The association between GMA findings, including MOS-R scores and GM trajectory between 35 to 40 weeks and the Amiel-Tison Neurological Assessment and DASII scores, was assessed by Spearman correlation, Fisher exact tests, and ordinal regression. Results: Moderate correlations were observed between MOS-R and the DASII motor DQ (Spearman r = 0.70, P < .001) and between MOS-R and DASII Mental DQ (r = 0.65, P < .001). The GMA trajectory at 35-40 weeks was associated with DASII motor DQ (Fisher exact, P = .002), and also with the Amiel-Tison Neurological Assessment at 9 months of corrected age (P < .01 by the Fisher exact test). On analysis by performing ordinal regression of predictive values of the general movements (GM) at 7 days of age, GM at 35 weeks, GM at 40 weeks, GM at 16 weeks, and MOS-R at 16 weeks, MOS-R alone was a statistically significant predictor of motor DQ at 1 year of age (OR -0.59; 95% CI -0.97 to -0.22; Wald statistics, P < .02). Conclusions: Consistent with findings in high-income countries, GMA including MOS-R scores performed in Indian infants born preterm during the neonatal period and early infancy is associated with neurodevelopmental outcomes in the first year of life. GMA can help initiate focused early intervention in low- and middle-income settings, where resources may be limited.
