The relationships between kinematic characteristics of sitting posture during reaching movements of the dominant arm and 1) the kinematics of the reaching movement itself and 2) functional performance during daily life activities (PEDI) were assessed in 51 sitting preterm children with cerebral palsy (CP). The children were 2-11 y, 33 had spastic hemiplegia (SH) and 18 bilateral CP (Bi-CP). The data were compared with those of 26 typically developing children (TD). Sitting posture before the onset of reaching of children with CP differed from that of TD children: they sat with a more reclined pelvis and a more collapsed trunk. The more reclined pelvic position was associated with a better quality of reaching movements. The different sitting postures of pelvis and trunk were not related to functional performance during daily life activities. Displacement of the head, trunk, and pelvis of the children with CP did not differ from that of the TD children. Nevertheless, in the children with CP a more stable head, a more mobile trunk, and a more stable pelvis were related to better functional performance and/or a better quality of reaching. This suggests that physiotherapeutic guidance of children with CP should focus rather on the latter postural parameters than on the different sitting posture of pelvis and trunk.

Kinematic characteristics of reaching movements of the dominant arm were assessed in 51 sitting preterm children who were aged 2-11 y and had cerebral palsy (CP), including 33 with spastic hemiplegia and 18 with bilateral CP (Bi-CP). Reference data of 29 typically developing children were present. The results indicated that the quality of reaching movements from the dominant arm of children with CP was significantly worse than that of typically developing children. This held true in particular for the children with Bi-CP. For example, reaching movements of children with CP took more time and consisted less often of one movement unit. The quality of reaching was related to the severity of lesion present on the neonatal ultrasound scan of the brain, the severity of motor disorder, the degree of spasticity, and the ability to perform activities of daily life. The last indicates that movements of the dominant arm in children with spastic hemiplegia and Bi-CP deserve clinical attention.
