“…In humans, small, slow, cyclic bending of the head and/or trunk are detected with 4D-ultrasonography at 5 weeks post-conception [8]. Waxing and waning general movements can be observed slightly later, at 7 weeks, and persist throughout pregnancy and the first months after term birth [9][10][11]. They consist of complex, variable, flexion-extensions of the whole body and limbs, they are not triggered by external stimuli and lack distinctive sequencing of different body parts.…”

Neural control of locomotion in human adults involves the generation of a small set of basic patterned commands directed to the leg muscles. The commands are generated sequentially in time during each step by neural networks located in the spinal cord, called Central Pattern Generators. This review outlines recent advances in understanding how motor commands are expressed at different stages of human development. Similar commands are found in several other vertebrates, indicating that locomotion development follows common principles of organization of the control networks. Movements show a high degree of flexibility at all stages of development, which is instrumental for learning and exploration of variable interactions with the environment

Fetal Behavior and Heart Rate in Twin Pregnancy: A Review

et al. 2013

Fetal movements and fetal heart rate (FHR) are well-established markers of fetal well-being and maturation of the fetal central nervous system. The purpose of this paper is to review and discuss the available knowledge on fetal movements and heart rate patterns in twin pregnancies. There is some evidence for an association or similarity in fetal movement incidences or FHR patterns between both members of twin pairs. However, the temporal occurrence of these patterns seems to be for the most part asynchronous, especially when stricter criteria are used to define synchrony. The available data suggest that fetal behavior is largely independent of sex combination, fetal position, and presentation. Conversely, chorionicity appears to have some influence on fetal behavior, mainly before 30 weeks of gestation. There is preliminary evidence for the continuity of inter-individual differences in fetal activity and FHR patterns over pregnancy. Comparisons between studies are limited by large methodological differences and absence of uniform concepts and definitions. Future studies with high methodological quality are needed to provide a more comprehensive knowledge of normal fetal behavior in twin pregnancy.

“…Prenatal and early postnatal development is marked by spontaneous movement (Bekoff, 2001;Birnholz, Stephens, & Faria, 1978;de Vries, Visser, & Prechtl, 1982;Geerdink, Hopkins, Beek, & Heriza, 1996;Hall & Oppenheim, 1987;Hamburger, Wenger, & Oppenheim, 1966;Thelen, 1979). Most of the early investigations of spontaneous motility concluded that these movements serve an adaptive function in early development (Coghill, 1929;Hooker, 1944;Hamburger et al, 1966).…”

“…Evidence for the continuity between early spontaneous activity and later appearing motor behaviors has been largely drawn from the following observations: (a) spatial or temporal patterning was similar between spontaneous movements and movements associated with an emerging skill (Bekoff, 1986;Thelen & Fisher, 1983), (b) developmental changes in spontaneous movements were continuous with those emerging for goal-directed behaviors in the limbs (de Vries et al, 1982), and (c) spontaneous activity in a muscle group predicted the rate of motor development of later appearing skills using those muscles (Thelen, 1979).…”

Early spontaneous orofacial movements have rarely been studied experimentally, though the motor experiences gained from these behaviors may influence the development of motor skills emerging for speech. This investigation quantitatively describes developmental changes in silent, spontaneous lip and jaw movements from 1 to 12 months of age using optically based 3D motion capture technology. Twenty‐nine typically developing infants at five ages (1, 5, 7, 9, and 12 months) were studied cross‐sectionally. Infants exhibited spontaneous facial movements at all ages studied. Several age‐related changes were detected in lip and jaw kinematics: the occurrence of spontaneous movements increased, movement speed increased, the duration of movement epochs decreased and movement coupling among different facial regions increased. Additionally, evidence for stereotypic movements was not strong. The present findings suggest that, during the first year of life, early spontaneous facial movements undergo significant developmental change in the direction of skill development for speech. © 2005 Wiley Periodicals, Inc.
