Assessment - Motor - Pathological Reflexes - Frontal Release Signs - Snout, Root, Palmomental

These patterned behavior reflexes appear when there is damage to the frontal lobes, which inhibits these primitive reflexes. In the normal person these reflexes are absent. Pressing a tongue blade on the lips tests for the snout reflex. The abnormal response is a pouting of the lips. The root reflex is tested for by gently stroking the lateral upper lip. The abnormal response is movement of the mouth towards the stimuli. Stroking the palm of the hand while watching for contraction of the ipsilateral mentalis muscle of the lower lip tests for the palmomental reflex. Physical Assessment Guide, Motor exam.
