Anomaly of the physiological response to maintain the body's posture when movement and position is altered.
Comment:
The primitive reflexes and the postural reactions comprise one of the earliest, simplest, and most frequently used tools among child neurologists to assess the central nervous system integrity of infants and young children. Infants with cerebral palsy have been known to manifest persistence or delay in the disappearance of primitive reflexes and pathologic or absent postural reactions. Primitive reflexes develop prenatally, are present at birth in the full-term neonate. Postural reflexes emerge after birth and take up to three and a half years to be fully developed.
