[Purpose] To determine whether the Gross Motor Performance Measurement is useful in
predicting the future score of the Pediatric Balance Scale, this study examined the
correlation between the 2 measurement tools with respect to movement disorder in children
with cerebral palsy. [Subjects and Methods] A total of 38 study subjects with cerebral
palsy were divided into 3 groups (spastic, dyskinetic, and ataxic) by means of systematic
proportional stratified sampling in accordance with the characteristics of their movement
disorders. [Results] The spastic Pediatric Balance Scale had an intermediate level of
positive correlation with dissociated movement (r=0.411), alignment (r=0.518), and weight
shift (r=0.461). The dyskinetic Pediatric Balance Scale had a strong positive correlation
with dissociated movement (r=0.905), coordination (r=0.882), alignment (r=0.930), and
stability (r=0.924). The ataxic Pediatric Balance Scale had an intermediate level of
positive correlation with the overall Gross Motor Performance Measurement (r=0.636), and a
strong positive correlation with dissociated movement (r=0.866), coordination (r=0.871)
and stability (r=0.984). [Conclusion] Gross Motor Performance Measurement is important in
evaluating the quality of movement, and can be considered an excellent supplementary tool
in predicting functional balance.
