Abstract
Introduction: Postural control is essential for daily activities. The first level of postural control deals with direction-specificity, meaning that a forward sway of the body primary elicits a response pattern in the muscles on the dorsal side of the body, while a backward body sway primary evokes responses in the ventral muscles. The second level of postural control is involved in the modulation of direction-specific activity on the basis of afferent input. Cerebral Palsy is the most common developmental disorder in childhood. It covers a heterogeneous group of disorders of posture and movement as a result of non-progressive brain damage. Children with CP generally show direction-specific muscle activation patterns, however with delayed development. The second level of postural control exhibits almost always abnormalities. Learning to sit independently does not seem to be associated with the development of postural control. This study examined how postural control develops in the period of learning to stand independently. Method: In a longitudinal study surface EMGs of neck, trunk, arm and leg muscles of 14 infants at high risk for Cerebral Palsy (HR) and 11 typical developing infants (TD) were recorded during reaching in sitting with or without support. The first measurement took place when the infant was able to sit, but not to stand independently (M1). At the second measurement they could stand independently (M2). The measurements were recorded on video. EMGs were analyzed with PedEMG. Statistical analyzes were performed with SPSS statistics, version 20.0. Results: In both the HR group and TD group, the prevalence of direction-specificity, recruitment order and anticipatory activity did not change in the period that the infants learned to stand independently. However, at M2 the frequency direction-specific activity was significant lower in the HR group than in the TD group at all measured levels of the body. The HR group also used the complete pattern significantly less frequently than the TD group at M2. In addition, in the HR group the frequency of anticipatory activity was significantly higher at trunk level than at the other measured levels of the body at M2. A similar differentiation was absent in the TD group. Conclusion: Development of postural control of the HR infants differs from that of TD infants in the period that they learn to stand independently. In both HR and TD groups development of the assessed components of postural control are not related to the ability to stand independently.
