Palmar Reflex: What It Is & Why It's Important

The palmar reflex is developed very early in utero and can be seen in infants born as early as 25 weeks premature. What exactly is this reflex and why is it important?
What is the palmar reflex?
In infants, the reflex can be seen when they are lying comfortably on their back, and you stroke their hand with your finger or other small object. They will respond by grasping the object. You may be familiar with this reflex by them grabbing your hair and not letting go. An easy way to release the reflex is to stroke the back of the hand and they will typically let go.
This reflex typically will disappear around age 2-4 months old. At this point, the baby is learning to reach and use their hands together to find toys and other objects. At this age, they reach and close fingers at the same time. As they develop into 6-7 months of age range, they then start to understand and improve the skills needed to reach to find the toys and items they want. This skill development sets up the ability for the pincer grasp, which is essential for handwriting and other fine motor skills.

What if I don't see this reflex?
If the palmar reflex is not integrated when your infant is younger than 2 months old, it can lead to these challenges as they get older:
- Poor handwriting
- Weak/absent pincer grasp (pinching with thumb and index finger)
- Lack of visual coordination
- Poor pencil grip
- Speech and language problems
- Anger control issues
- Sticking tongue out when using hands
- Hypersensitive to various textures and sensations on the hands
- Back aches when sitting
