Motor development and postural control
Michael Horvat, Ronald V. Croce, Caterina Pesce, Ashley Fallaize in Developmental and Adapted Physical Education, 2019
The asymmetrical tonic neck reflex in a supine position is elicited by rotation or lateral flexion (tilt) of the head leading to increased extension of the limbs on the chin side with accompanying flexion of limbs on the head side (Figure 5.2). Persistence of the reflex will cause difficulty in rolling, because the extended arm impedes rolling. Furthermore, the reflex interferes with holding the head in the midline, resulting in visual perceptual problems commonly associated with tracking or fixating on objects. The reflex is also evident in skills such as catching and throwing, where one elbow is bent while the other extends because the head position is rotated or tilted to track a ball. In sports such as tennis or baseball, rotation of the head will interfere with crossing the midline and smooth integration of the movement.

Fukuda72 described the tonic neck reflex which appears by rotation of the head and consists of extension of the jaw and flexion of the contralateral extremities, thus forming a basic pattern of human movement. By using this reflex, the postures assumed in various sports such as archery, shot-put, and high jump, are timed to coincide with the application of maximum muscular strength.
Eye and hand skills
Jill Christmas, Rosaline Van de Weyer in Hands on Dyspraxia: Developmental Coordination Disorder, 2019
The child may tend to ‘pen push’, which may be due to the retained presence of an asymmetrical tonic neck reflex. An involuntary extension movement of the arm may be elicited by the child turning their head to look at their writing hand. (This movement can be clearly seen in very young babies – see the section on asymmetrical tonic neck reflex in Chapter 7 for further information.)

Inhibition of undesired movement patterns like Symmetrical Tonic Neck Reflex (STNR), Asymmetrical Tonic Neck Reflex (ATNR), TLS, and TLP reflexes inhibition by weight bearing in particular positions of prone on elbow, quadroped, and prone on hand.Facilitation of higher-level reactions, such as the engagement of the upper extremities for balance and protective reactions while standing, kneeling, or quadroped.Hand active movements exercises, including hands coordination, moving objects between two hands, crossing body midline with each hand, unilateral and bilateral diagonal displacement patterns, grasping and releasing objects.

WHEN WE OBSERVED PSH: The patient remained on sedation for a prolonged course due to several complications related to his injury. At approximately day 30, he developed episodes of autonomic instability with tachypnea, tachycardia, irritability, and spasticity. On examination, he had right-sided flexor tone, MAS 3–4, left-sided extensor tone MAS 2–4, bilateral hamstring and plantar-flexor tone MAS 3–4, and asymmetrical tonic neck reflex.
