The effect of vibroacoustic stimulation on the nonstress test at gestational ages of thirty-two weeks or less.
The effect of vibroacoustic stimulation on the nonstress test at gestational ages of less than or equal to 32 weeks was studied in 15 patients who underwent a total of 316 nonstress tests starting at 20 to 25 weeks' gestation. There were 168 nonreactive nonstress tests that were followed by 3 seconds of vibroacoustic stimulation. The incidence of reactive nonstress tests after vibroacoustic stimulation was significantly increased after 26 weeks' gestation. This may have clinical applicability and may be related to functional maturation of the fetal auditory system.
