The Relationship between the School Function Assessment (SFA) and the Gross Motor Function Classification System (GMFCS) in Ambulatory Patients with Cerebral Palsy.



Determine the relationship between the SFA and GMFCS in children with cerebral palsy (CP).


Through correlation, regression, and ANOVA analysis, data from 103 children were examined. A regression model was used to compare SFA-predicted versus actual GMFCS levels. One-way ANOVA was utilized to determine differences between SFA subscale scores in the context of GMFCS.


A significant correlation between composite SFA scores and GMFCS levels (r = -0.847, p < 0.020) was observed. Subscale-SFA and GMFCS correlations included Regular Class (r = -0.338, p < 0.001), Physical Tasks Adaptation (Phys1; r = -0.340, p < 0.001) and Assistance (Phys2; r = -0.340, p < 0.001), Position (r = -0.338, p<0.001), Recreational Movement (RecMvmt; r = -0.387, p <0.0001), Manipulation Movement (ManMvmt; r = -0.494, p < 0.0001), and Up/Down Stairs (UDStairs; r = -0.453, p< 0.0001). Between predicated and actual GMFCS levels, no statistical difference was observed. One-way ANOVA demonstrated SFA differences at GMFCS levels: Phys1 (F= 5.32, p < 0.002), Phys2 (F = 4.54, p < 0.005), Position (F = 4.63, p < 0.004), RecMvmt (F = 7.92, p < 0.0001), ManMvmt (F = 13.50, p < 0.0001), and UDStairs (F = 6.18, p < 0.001).


Utilizing both SFA-predicted and actual GMFCS levels may help determine if a child is performing at an expected level of daily function.
