Foot Grasp Reflex

How to perform the "Foot Grasp Reflex"?

• The reflex is tested with the infant supine. 
• When light digital pressure is applied to the plantar surface of the foot (especially on its distal portion just proximal to the toes), tonic flexion and adduction of the toes should occur. 

What is the positive result?

• The plantar grasp reflex is present in neonates and infants, and usually disappears between 9 and 12 months of age. 
• Its absence may indicate flaccid paralysis. 
• Its persistence beyond 1 year of age may be due to spasticity of the leg and foot muscles. 
• The reflex may also persist in children with birth injuries and delayed development.
