Background : Non-Stress Test (NST) is one of the most common methods used to evaluat fetus health, which its results are presented as reactive and non-reactive. One of the limitations of this test is the high number of false non-reactive cases. Different studies have suggested a combination of vibroacoustic stimulation and NST to reduce the number of non-reactive cases and duration of the test. Materials and Methods: The present study examined a group of tests, and used simple randomized sampling. The number of the sample was 55 individuals and the data collection tools were NST, sonography instruments, NST result paper, a tooth brusher, a watch, a demographic questionnaire, and a checklist. Vibroacoustic stimulation with an electronic brush was performed on fetus head situated on mother’s abdomen for 3 seconds and then NST was continued for a further 20 minutes. Then the results were recorded. The obtained data were gathered by SPSS 19 software, and analyzed using descriptive statistics. Results: In this study, 85.5% of the non-reactive cases changed into reactive through vibroacoustic stimulation. The amount of false positive was lower with vibroacoustic stimulation in comparison with NST. Conclusion: Vibroacoustic stimulation, as a technique for evaluating fetus health, makes it possible to save time, costs and personnel. It is also leads to sooner and better diagnosis of fetus health.
