Comparison of motor performance parameters in relation to the CP children's MACS score. Figure 5a, b, c and d depicts the responses for the pooled data from the computer manipulations 10, 15 and 20 degrees divided into the MACS score groups for the CP children. Only the functional measurements where we found a significant difference between the CP children and the healthy groups are displayed. Significant differences between the MACS score and the motor performance parameters (time, curvature and drift) was observed for their responses of subjective reporting of being responsible for the visual object or not (p < 0.033). For time and drift measurements, there is a significant difference between the two MACS groups when reporting either Yes or No, whereas there is a significant difference between the reporting rate depending on the amount of curvature for both MACS score groups.
