The effect of music therapy on the cardiac activity parameters of a fetus in a cardiotocographic examination.

OBJECTIVE: The assessment of cardiac parameters of the fetus in cardiotocographic record of pregnant women listening to classical music.

STUDY DESIGN: Sixty NST records with no musical stimulation and 30 NST records during a 15-min auditive stimulation with Wolfgang Amadeus Mozart's "Turkish March" as well as 30 NST records during Johann Strauss's "Tritsch-Tratsch Polka" were performed for the study. The average stage of the responders' pregnancy was the 36rd week, the lowest - the 27th week, the highest - 41st.

RESULTS: Following the listening to W.A. Mozart's composition, a significant increase was observed in values concerning: the number of fetal movements (p < 0.0001), accelerations >10 (p = 0.0063), accelerations >15 (p = 0.0011), high variability (p = 0.0019) and short-term variability (p < 0.0001). Meanwhile, parameters concerning baseline cardiac activity (p = 0.0003) and low variability (p = 0.0021) significantly decreased. The number of uterine contractions decreased insignificantly (p = 0.3718). Following listening to J. Strauss's composition, the following parameters underwent increase: fetal movements (p = 0.0021) and short-term variability (p = 0.0025). The remaining parameters of the cardiotocographic record: accelerations, uterine contractions - underwent an improvement, but the changes were not significant.

CONCLUSION: Music therapy is a noninvasive and uncostly method, significantly improving wellbeing-indicative fetal parameters.
