“…The lack of response can be explained by the fact that the study was carried out in the sleep phase, which is not always possible to take into account based on the subjective feelings of the woman. It is also possible the influence of some technical aspects of the test, as well as the woman's characteristics, for example, excess subcutaneous tissue, the amount of amniotic fluid, since the amniotic environment and adipose tissue play the role of a filter in the perception of external sound stimuli [19].…”

Object of study: pregnancy in women with a history of cesarean section, perinatal period. The problem to be solved: clarification of the perinatal significance of the factor “scarred uterus”, substantiation of the clinical significance of the test with acoustic stimulation of the fetus as a method for predicting early neonatal adaptation. Main scientific results: it was found that pregnancy in women with a history of cesarean section is characterized by an increased perinatal risk and is associated with psychoemotional stress of the mother, which affects the reactivity of fetal cerebral hemodynamics. It has been shown that the test with acoustic stimulation of fetus allows one to gain an idea of the fetus's perception of stressful influences, which should be taken into account when drawing up a delivery plan. The area of practical use of research results: obstetric departments of maternity hospitals and multidisciplinary hospitals. An innovative technological product: technology for assessing the state of the fetus in full-term pregnancy, which allows predicting complications of early neonatal adaptation based on the susceptibility of the fetus in the test with acoustic stimulation. Scope of application of an innovative technological product: obstetric clinical practice, perinatal medicine.

“…[ 8 ] Because of these stimulation programs, children become habituated to their environment faster and grow more effectively. [ 4 ] Habituation means that neonates gradually reduce their response to a repetitive stimulus and allow that stimulus to be ignored and, doing so, their energy is stored for physiological needs. [ 9 ] Habituation is a useful criterion for evaluating the neurobehavioral health of the neonate.…”

“…These techniques can enhance brain development and fetus's learning, thereby promoting the mother-fetus relationship in both perinatal and postnatal periods. [ 4 ] Paradoxically, although it has been argued that the natural sensory environment of the uterus is suitable for the fetus development, the intrauterine sensory stimulation programs have not been extensively studied and cannot be proven to be beneficial. [ 12 ] Thus, the researcher decided to use a program to stimulate fetal sensory systems based on a review of the available literature in order to examine the effectiveness of these stimulus programs on newborn behavior.…”

“…Nevertheless, this area has experienced slow progress in the development of technologies to objectively evaluate foetal movement behavior for clinical application [2,18]. There are even authors who discuss how dangerous an ultrasound test may be to foetuses, as some observations of foetal locomotor activity during the ultrasound diagnostic procedure have suggested that foetuses respond unfavourably to modulated ultra-sonic irradiation, and this impact would thus be better explored in simulated wombs [20]. A more frequent line of research that comes out in a literature search is the study of the impact of music therapy on pregnant women and their foetuses or ill neonates [21,22].…”

Music perception in foetuses has been explored under different theoretical paradigms such as habituation, categorical perception, sound preferences and recall. This study investigated the temporal dimension of music perception through the habituation and sensitization paradigm. Foetuses of 41 pregnant women, mean gestational age of 34.7 weeks (±2.4), were observed during ultrasound exams. Foetuses’ reaction to two different tempos (Allegro vs Adagio) and sources (internal vs external) of music stimuli was registered by heart rate variability (HR) and motor response according to the Assessment of Preterm Infants Behaviour scale (APIB) by its factors of movement (MOV) and organization (ORG). A folkloric lullaby, sung and played live with a stringed instrument by a musician, was presented in three stages that were compared to baseline: 1) slow tempo (Adagio), 2) fast tempo (Allegro); and 3) now sung by mother at slow tempo (Adagio). Exploratory analyses showed that all factors increased from baseline to first stage. HR and ORG varied significantly among stages, with HR being the strongest factor. MOV merely detected change from baseline to first stage. ORG decreased for Allegro but increased for maternal Adagio, while HR decreased to near baseline values. ANOVA-repeated measures with gestational age as covariate showed that all measures were sensitive to first music presentation (Adagio), although only HR and ORG differed among stages. Considering estimated marginal means, adjusted for gestational age, HR presented a sensitization pattern throughout stages, but ORG kept habituating to external source and increased to maternal Adagio, suggesting foetal discrimination by sound source. We conclude that foetuses showed different behavioural and physiological responses to external versus internal sound source and musical tempo. The combined use of a behavioural scale (APIB) and HR in foetuses proved to be a valid multidimensional instrument.
