Abstract: Objective To investigate the consistency of Infant Neurological International Battery (Infanib) and Gesell developmental scale in the assessment of motor development in high-risk infants.Methods From May 2022 to April 2023, 132 high-risk children were collected from our hospital as research subjects. Kappa values were calculated to determine the consistency of Infanib and Gesell developmental scales.Results The evaluation results of Infanib scale was consistent with that of Gesell developmental scale in 111 of the 132 children (84.09%),including 90 being assessed as normal and 21 as borderline (suspected) or developmental delay. The consistency was 0.57 in the assessment of gross motor quotient for Infanib scale and Gesell developmental scale. The consistency of the two scales was 0.62, 0.67 and 0.41 in children under 4 months, between 4 and 8 months and over 8 months. In the high-risk term infants, the consistency of evaluation by Infanib scale and Gesell developmental scale was 0.61, which was 0.32 in high-risk preterm infants.Conclusion The consistency of Infanib and Gesell developmental scales is generally good, but low in children >8 months of age and children at high risk of preterm birth. It is suggested that different scales should be selected according to the age and birth situation of children to accurately reflect the true level of children's motor development.
