[Purpose] This study attempted to investigate the effect of
physical therapy frequency based on neurodevelopmental
therapy on gross motor function in children with
cerebral palsy. [Subjects and Methods] The study sample included 161 children with
cerebral palsy who attended a convalescent or rehabilitation center for disabled individuals or a special school for children with physical disabilities in South Korea. Gross Motor Function Measure data were collected according to
physical therapy frequency based on neurodevelopmental
therapy for a period of 1 year. [Results] The correlation between
physical therapy frequency and Gross Motor Function Measure scores for crawling and kneeling, standing, walking, running and jumping, and rolling, and the Gross Motor Function Measure total score was significant. The differences in gross motor function according to
physical therapy frequency were significant for crawling, kneeling, standing, and Gross Motor Function Measure total score. The differences in gross motor function according to frequency of
physical therapy were significant for standing in Gross Motor Function Classification System Level V. [Conclusion] Intensive
physical therapy was more effective for improving gross motor function in children with
cerebral palsy. In particular, crawling and kneeling, and standing ability showed greater increases with intensive
physical therapy.
