The results showed that there were no significant differences between the groups based on age, stature, body mass, body fat percentage, or maturational status. However, mechanical power output was significantly higher in the participants with CP, but there was no difference between the groups in energy transferred. The study concluded that the large amount of the variability in the O2 cost of walking in children with CP are accounted for by the total body mechanical power estimates that allow energy transfers within and between adjacent segments of the same limb, that there were no significant correlations between total energy transfers and the O2 cost of locomotion for both sets of participants, and that there appears to be a threshold that exists beyond which changes in mechanical power are associated with an elevated O2 cost of locomotion in children with CP.
