The article presents the primary results of prospective cohort study of fetal activity in the third trimester of physiological pregnancy.

The objective: the establishment of periods of spirits and emotional activity of the fetus in the third trimester of physiological pregnancy.

Materials and methods. The study included 300 somatically healthy patients in the period of 28 weeks of pregnancy with a non-obstructed obstetric anamnesis, a single-fetal physiological pregnancy that occurred in the natural cycle, with normal results of the I and II prenatal screenings that were in the Kyiv city hospital No.2 and the medical center «Uniklinika» in 2015–2016.

Results. The frequency and strength of the shocks are analyzed depending on the time of the day and the gestational age.

The conclusion. It is established that the most emotionally active period of the fetus falls on the evening hours – from 20:00 to 23:00. The maximum frequency of tremors is typical for the period 28-32 weeks of gestation, the maximum force of tremors is observed between the 32-nd and 36-th weeks of pregnancy.

Key words: actography, fetal movements, intrauterine homeostasis.
