Primitive Reflex
Palmar Reflex
The grasp reflex — foundation of fine motor control, handwriting, and articulation.
The Palmar grasp reflex (or grasp reflex) is a primitive, involuntary reflex found in infants of humans and most primates. When objects contact an infant's palm, the infant's fingers reflexively grasp the object. The presence of this reflex signals typical neurological development.
The reflex appears around 11 weeks gestation and typically remains active until 3–6 months of age, coinciding with intentional hand control development.

- •Poor manual dexterity
- •Poor handwriting
- •Mouth movements during writing or drawing
- •Speech and articulation issues
- •Hands held in fist at rest
- •Tight grasps on utensils
