Article Summary

Predictive value of the Movement Assessment Battery for Children – Second Edition at 4 years, for motor impairment at 8 years in children born preterm.

Purpose

The main purpose of this study was to determine the efficacy of the Movement Assessment Battery for Children – 2nd Edition (MABC-2) as a prognostic tool for motor outcomes for children born preterm (<30 weeks gestation). Specifically, the research administered the test at four years of age and followed up at eight years in order to explore any association of motor outcomes, as well as any other related outcomes.

Methods

The study originally consisted of 120 children born <30 weeks gestation who originally were recruited for a previous RCT examining developmental outcomes. The researchers included information from said RCT as there was no significant difference between groups. The participants were followed up at four and eight years old in which the MABC-2 was conducted. Between both follow ups, 24 subjects were unable to continue with the study. The remaining 96 were included with the initial data analysis while the original group were included for secondary analysis. Six children were diagnosed with CP and were found to be in the lowest 5th centile during both follow ups.

Results

Motor impairment remained stable at 25% between four and eight years of age. The rate of motor impairment with scores in the 5th centile for males decreased from 40% at four years old to 32% at eight years old, while females increased from 7% to 16% respectively. The MABC-2 was found to have a sensitivity of 79 (58, 93), specificity of 93 (85, 98), positive predictive value of 79 (58, 93) and negative predictive value of 93 (85, 98). From the results, there was a strong correlation found from age four to eight for motor impairments. Additionally, the authors found that at motor impairment at age eight was correlated with high medical risk and cognition that was below average. Total standard score changes were found to have little evidence of correlation with sex, medical risk, social risk, or General Conceptual Ability score.

Limitations

Only 19 of the 96 children were found to have motor impairments during the follow ups. Such a small number limits the predictive efficacy of the MABC-2 compared to a larger group. Another limitation mentioned by the authors included “uncooperativeness” by the participants which may have skewed data trends towards impairments in motor function.

Conclusion

Based on the current research, there is evidence to suggest that the MABC-2 performed at four years old provides predictive validity for impairments in motor function at eight years old in children who were born <30 weeks gestation. Specifically, the authors found that of this population, participants scoring at or below the 5th centile have a high projected likelihood for future motor impairments.
