Exploring a large data set, hypertonicity of the lower extremities has been incidentally identified as occurring in one out of every five infants, whether term or preterm. This retrospective, longitudinal, descriptive, quantitative study examined data from 463 functionally and structurally normal infants and identified infants that were considered to be hypertonic at either hospital discharge and at one month of corrected gestational age to determine what their motor capabilities were at 13 months of age. Understanding the correlation will assist in determining whether early intervention is indicated for these infants. Multiple statistical analyses revealed no correlation between hypertonicity as a young infant and the Bayley-II motor function score at 13 months of age. The Roy Adaptation model was used as the conceptual framework of the study and ordinal regression was utilized to analyze the data.
