Fig 1 A comparison of a COP excursion in a representative trial of a boy with CP (identification number [ID] 9; age: 82mo; seated height: 82.5cm; total PRT score: 36.9) and an age-matched TD boy (ID 13; age: 81mo; seated height: 87.5cm; total PRT score: 80.6) in all 3 reach directions (top: anterior; middle: lateral; and bottom: medial). A square indicates the beginning of reaching for the target, and a star denotes touching the target.

Fig 2 The changes of the COP SR at all 3 reach directions in both groups. The dash line is plotted at SR=1, which means the COP-AP cumulative path is equal to the COP-ML path.

Fig 3 A profile of mean pushing and braking forces for each participant with CP and TD during hand acceleration and deceleration in all 3 reach conditions (A, chair data; B, feet data). Positive GRF-AP represents the braking effect, and negative GRF-AP represents the pushing effect.
