The newborn neuromuscular system can be initially assessed by 6 quick tests (posture, square window, arm recoil, popliteal angle, scarf sign and heel to ear). Later developmental assessment includes behaviour, reflexes (primitive and postural), muscular tone, and motor (gross, fine, co-ordination).

* '''Distinct locomotor precursors in newborn babies'''{{#pmid:32284405|PMID32284405}} It is commonly thought that human locomotor development stems from a single precursor behavior, consisting of alternating flexor–extensor movements, such as kicking or stepping on ground. According to this view, kicking and stepping are identical movement patterns generated by the same neural mechanisms. Here we show that the neuromuscular modules of neonatal kicking and stepping are different, presumably related to different neural mechanisms. Kicking involves an adult-like number of temporal activation patterns, whose association with specific sets of muscles varies across movements. Ground-stepping involves a limited number of activation patterns, each associated with a stable muscle synergy. Since neonatal kicking and ground-stepping seem to anticipate subsequent developmental changes of locomotion in human babies, they might represent distinct locomotor antecedents." | |||

Introduction
Neurological development continues postnatally with both growth and reorganization of the central nervous system. The amount of simple physical growth is shown by the skeletal flexibility designed around the brain and spinal cord, which allows continued postnatal growth of these structures. The World Health Organization (WHO) recently identified early postnatal motor skill development in terms of "motor milestones"[1], this was released along with new international growth charts.
The following movies demonstrate normal and abnormal postnatal neurological development assessment procedures.
The newborn neuromuscular system can be initially assessed by 6 quick tests (posture, square window, arm recoil, popliteal angle, scarf sign and heel to ear). Later developmental assessment includes behaviour, reflexes (primitive and postural), muscular tone, and motor (gross, fine, co-ordination). This is examined in the newborn, 3 months, 6 months, 12 months and at 30 months of age. There are several primitive reflexes (rooting, sucking reflexes, Moro, grasp) that change (are repressed) with development of the central nervous system.
These movies were designed by PD Larsen and SS Stensaas, Utah School of Medicine.
