Predicting Neuromotor Outcome in Very Low Birth Weight Infants at One Year of Corrected Age Using Movement Assessment of Infants Scale

The purpose of this study was to find the validity of MAI in predicting neuromotor outcome in Very Low Birth Weight Infants (VLBW) at one year of corrected age.

Infants(n=40) born with birth weightd”1500gms and admitted to NICU were assessed at 4 months of corrected age using MAI scale and follow up evaluation for motor and mental development was done with a neuropschycological tool, Bayley Scale of Infant Development (BSID II) at 12 months of corrected age.

The predicted neuromotor outcome at 12months on motor items of BSID were 70% sensitivity, 83.3% specificity, 58.3% positive predictive value and 89.3% negative predictive valve and for mental items were 60% sensitivity, 74.3% specificity, 25% positive predictive value and 92.8% negative predictive valve with a cutoff score of e”10 on MAI.

The MAI administered at 4 month is a useful clinical tool with high specificity and acceptable sensitivity in predicting neuromotor outcome at one year of corrected age in VLBW infants.
