Primitive Reflexes[edit | edit source]

The primitive reflexes are movement patterns that can be involuntarily elicited in a newborn. They exist to enhance chances of survival. These reflexes should be integrated as the child's motor development matures. The persistence of these reflexes beyond the usual ages of integration is suggestive of ischemic brain injury. Below several of the primitive reflexes, their appearance and integration dates are discussed.
