Plantar flexion of the foot-when assessing the plantar reflex, observe for plantar flexion where the toes curl toward the sole of the foot.
the babinski response is dorsiflexion of the great toe and fanning of the other toes when eliciting the plantar reflex. the babinski response is considered abnormal in an adult and may indicate upper motor neuron disease. a positive babinski response is considered a normal response in a child until about 2 years of age.
dorsiflexion of the foot is not a normal plantar reflex response.
fanning of the toes occurs with a positive babinski.
