The Palmar reflex is the automatic flexing of fingers to grab an object and should integrate by six months. One of the key first steps in developing fine motors skills, is the development of the Palmar grasp. The Palmar grasp involves your child learning to grab an object with their whole hand – including their thumb. If the Palmar reflex is retained, a child may have difficulty with fine motor skills, stick out tongue while writing, and exhibit messy handwriting.

• If people have retained palmar reflex, they tend to have:
• Poor handwriting
• Poor pencil grip
• Poor fine muscle control
• Poor dexterity
• Hand weakness
• Poor fine motor skills
• Poor vision coordination
• Slumpy posture when using hands
• Backaches when sitting
• Sticks tongue out when using hands
• Poor pencil grip
• Poor ability to put thoughts to paper
• Dysgraphia
• Speech and language problems
• Anger control issues
• Even if they don't display any of these symptoms, it is a good idea to do a quick test on them, as there may be other functions that are affected by it that are still unknown.
