Design outcomes

Primary

MeasureTime frame
Expected Outcome 1: To evaluate the reaction of children to musical stimuli that were previously exposed in fetal life, using the heart rate measurement method for one minute and using a stethoscope. ;Found Outcome: It was observed that 84.61% of children exposed to musical stimulus during pregnancy respond, in the first 6 weeks of life, with decreasing heartrate during the execution of the same stimulus. Of those who decreased the heart rate (11 newborns), the average variation was 11.27 bpm, with a minimum of 3 and a maximum of 16.

Secondary

MeasureTime frame
Expected Outcome 2: Compare heart rate change between the experimental and control groups by classifying HR variation into two groups: decrease, if heart rate slows down, or neutral and increase. ;Found Outcome 2: When classified into two groups, it was observed that 11 newborns from the experimental group decreased heart rate and 2 increased. It was observed, in the control group, that 2 newborns decreased heart rate and 11 increased or remained neutral. Thus, when compared the variation of the heart rate and the experimental and control groups, statistical significance was found, pvalue: 0.0017
