Table 3: Mean and standard deviation of dependent variables of angular changes in axial and lower extremity components during the hand deceleration phase. In summary, no interactive effect was found in head or trunk movement during the hand deceleration phase of reaching. Different angular patterns were observed in pelvis, hip, and ankle motion between groups. Children with CP rotated the pelvis toward the lateral side when performing the movement of lateral ankle supination when reaching laterally. TD children did not rotate the pelvis, but abducted the hip laterally when performing lateral ankle pronation. During medial reach, all children rotated the pelvis toward the medial side, but children with CP performed fewer degrees of rotation than did children with TD. Children with CP did not adjust subtle lateral hip abduction as TD children did; however, children with CP adducted the medial ankle, but TD children kept it motionless during hand deceleration for medial reach.
