The reflex was elicited mechanically by a light tap on the glabella. Stepping reflex. Test can indicate both neurological damage and nerve regeneration; often combined with the Babinski reflex test. [2] Landau reflex: Placing the infant in a prone position elicits arching of the back and raising of the head. The EMG-responses were recorded bilaterally from the orbicularis oculi muscles by pairs of surface electrodes. An abnormal response is slower and consists of extension of the great toe with fanning of the other toes and often knee and hip flexion. There are many ways to elicit Moro reflex. However, the most common method used is the “drop method” wherein the nurse lifts the baby completely off the bed while supporting the head and the neck, and then the nurse lowers the baby rapidly till there is only 4-8 inches between the baby and the bed. Moro Reflex. Testing merely for the presence or absence of the reflex therefore lacks both specificity and sensitivity. 4–6 months; Persistent glabellar tap sign is a frontal release sign called Myerson sign. The normal reflex response is flexion of the great toe. The glabellar reflex (GR) was investigated in 15 patients with hemiplegia and in 10 control subjects. Tapping the glabella elicits blinking. The grasp reflex lasts until the baby is about 5 to 6 months old. This reflex is also called the walking or dance reflex because a baby appears to take steps or dance when held upright with his or her feet touching a solid surface. Glabellar tap sign. Myerson's sign also called as glabellar tap sign is a medical condition where a patient is unable to resist blinking when tapped on the glabella, the area above the nose and between the eyebrows. Release, primitive, foetal, developmentalor atavistic reflexes:• Release reflexes group of behavioural motor responses originating in the central nervous system that are exhibited by normal infants but not neurologically intact adults, in response to particular This reaction is of spinal reflex origin and indicates spinal disinhibition due to an upper motor neuron lesion. 8. Release reflexes 1. This reflex … A similar reflex in the toes lasts until 9 to 12 months. A strong, sustained, and easily repeatable contraction of the mentalis muscle, which can be elicited by stimulation of areas other than the palm, is more likely to indicate cerebral damage.

Glabellar reflex; Golgi tendon reflex; Hering–Breuer reflex — is a reflex triggered to prevent over-inflation of the lung; Hoffmann's reflex — also known as the finger flexor reflex; middle finger and thumb response.
