Welcome back for post 4 of the primitive reflexes blog series!
We have completed the primitive reflexes that emerge before birth and reflexes that emerge shortly after birth. This post will discuss the reflexes that are not integrated and persist throughout life.
Lets get started!
The group of reflexes about to be discussed are known as the “protective reflexes.”
Downward Parachute (Protective Extension Downward)
- Onset: 4 months
- This reflex is elicited by quickly lowering the baby toward a surface while being held vertically in the air. In response, the baby will extend both of their legs as a protective response.
- Significance: protective defense against a fall or an anticipated fall with accurate placement of the feet onto the ground
Forward Parachute (Protective Extension Forward)
- Onset: 6-9 months
- This reflex is elicited by quickly tipping the baby forward while being held vertically in the air. In response, the baby will extend (straighten) their neck, upper extremities (arms), and have open hands as a protective response.
- Significance: protective response to support the body against a fall or an anticipated fall forward if needed
Sideward Parachute (Protective Extension Sideward)
- Onset: 7 months
- This reflex is elicited by quickly tipping the baby to the side off balance while seated. In response the baby will extend their arm to the side as a protective response.
- Significance: protective defense against a fall or against an anticipated fall
Backward Parachute (Protective Extension Backward)
- Onset: 9-10 months
- This reflex is elicited by quickly tipping the baby off balance backward while sitting. In response the baby will extend both arms backward or 1 side of spinal rotation with one arm extended as a protective response.
- Significance: protective defense again a fall or again an anticipated fall backward
If there is a deficit within these reflexes you will see the child:
- Have an absence of coordination
- Low muscle tone
- The child will consistently crash or run into objects
- Inability to sit up for long periods of time
- Lack of attention span
- Having a dependent or scared child
