Overall, 137 newborns (71 boys and 66 girls) at the age of 10–14 days were examined. The following set of methods was used: a comprehensive assessment of neonate physical development according to tables of the centile type, the determination of indicators of spontaneous motor activity (SMA) during the daily cycle, the assessment of the main cardiovascular system (CVS) data and daily monitoring of heart rate, heart rate variability parameters, the study of psychomotor status based on the state of muscle tone, evoked reflexes, and movements. The results of the study revealed the typological variability of spontaneous motor activity in healthy newborns in the late neonatal period with the identification of three functional types: newborns with low, medium, and high SMA. Complex evaluation of morphofunctional data, vegetative homeostasis, and psychomotor status in newborns with different levels of SMA identifies three variants of the physiological norm of psychomotor development: tonic (low SMA), harmonic (medium SMA), and kinetic (high SMA). 收起
