Insights
This study developed two versions of a body function index in cerebral palsy (BFI-CP) to assess children
Area of Science:
- Pediatrics
- Rehabilitation Medicine
- Biostatistics
Background:
- Cerebral palsy (CP) significantly impacts children's functional abilities.
- Accurate assessment tools are crucial for understanding and managing CP.
- Existing classification systems like the Gross Motor Function Classification System (GMFCS) have limitations.
Purpose of the Study:
- To develop two versions of a body function index in cerebral palsy (BFI-CP I and BFI-CP II).
- To examine the relationship and differences between BFI-CP I, BFI-CP II, and the GMFCS.
- To explore classification differences beyond GMFCS ordinal levels.
Main Methods:
- Utilized data from 405 children with CP (18 months to 5 years) from the Move & PLAY Study.
- Developed BFI-CP I using a summing technique.
- Developed BFI-CP II using cluster analysis.
Main Results:
- Strong correlations were found between BFI-CP I and GMFCS (r=0.92), BFI-CP II and GMFCS (r=0.93), and BFI-CP I and II (r=0.92) (p<0.001).
- Significant differences were observed between BFI-CP I and GMFCS (χ²=670.49, df=16, p<0.001).
- Significant differences were also noted between BFI-CP II and GMFCS (χ²=685.57, df=16, p<0.001).
Conclusions:
- The two BFI-CP versions demonstrate strong correlations with the GMFCS.
- Both BFI-CP versions show significant differences compared to the GMFCS.
- The BFI-CP I and BFI-CP II can serve as complementary tools for describing children with CP.
Abstract:
The purpose was to develop two versions of a body function index in cerebral palsy (BFI-CP I and BFI-CP II) using two methods to explore the relationship and differences among them and the Gross Motor Function Classification System (GMFCS) and to explore the differences among subsets of the classifications that do not correspond to the ordinal levels of the GMFCS. Data on various measures from 405 children with CP between 18 months and 5 years of age were extracted from the Move & PLAY Study. The BFI-CP I was developed using a summing technique and the BFI-CP II was developed using cluster analysis. There was a strong correlation between the BFI-CP I and the GMFCS (r = 0.92), between the BFI-CP II and the GMFCS (r = 0.93), and between the BFI-CP I and II (r = 0.92) all (p < 0.001). There was also a significant difference between the BFI-CP I and the GMFCS (χ2 = 670.49, df = 16, p < 0.001) and between the BFI-CP II and the GMFCS (χ2 = 685.57, df = 16, p < 0.001). The findings of this study indicate that the two versions of the BFI-CP could be used as complementary methods in describing children with CP.
