Data from 3 children in the CP group were excluded due to 1 having questionable diagnosis
of CP, and 2 who were unable to walk without assistance from an investigator during the
testing session. Data for the remaining 31 children were used for analysis. Walking
experience did not differ between groups (p=0.969). As expected, because of a later onset of
walking in the CP group and matching by walking experience, the TD group was older and
heavier than the CP group. Of the children with CP, 7 were classified as GMFCS level II
and 8 were level III. Three walked without assistive devices, 9 used posterior rolling
walkers, 1 used bilateral forearm crutches, and 2 used unilateral forearm crutches.
Demographic and anthropometric data are provided in Table 2.
