Sitting Postural Control in Infants With Typical Development, Motor Delay, or Cerebral Palsy

Nonlinear Dynamics of Infant Sitting Postural Control

Background: Upright sitting is one of the first developmental motor milestones achieved by infants, and sitting postural sway provides a window into the developing motor control system. A variety of posture sway measures can be used, but the optimal measures for infant development have not been identified. Methods: We have collected sitting postural sway data from two groups of infants, one wit...

Sensory information utilization and time delays characterize motor developmental pathology in infant sitting postural control.

Sitting is one of the first developmental milestones that an infant achieves. Thus measurements of sitting posture present an opportunity to assess sensorimotor development at a young age. Sitting postural sway data were collected using a force plate, and the data were used to train a neural network controller of a model of sitting posture. The trained networks were then probed for sensitivity ...

Approximate entropy used to assess sitting postural sway of infants with developmental delay.

Infant sitting postural sway provides a window into motor development at an early age. The approximate entropy, a measure of randomness, in the postural sway was used to assess developmental delay, as occurs in cerebral palsy. Parameters used for the calculation of approximate entropy were investigated, and approximate entropy of postural sway in early sitting was found to be lower for infants ...
