Monitoring of pregnant women before delivery routinely includes the non stress test (NST), which is often used in third trimester of pregnancy. Fetal heart rate (FHR) reactivity time differs in all cases. It is observed that maternal position may be the case for it. Aim of the study is to determine whether maternal position during NST influences the fetal parameters. To obtain post intervention data of fetal parameters of NST and to compare the difference related to fetal parameters of NST in three positions. Quasi experimental “three group” with ‘pretest’ and ‘post test’ approach was used. All antenatal mothers who are 32 to 40 weeks of gestation for non stress test for 20 minutes were selected. 30 samples were assigned in E1, E2 and E3 group. Purposive sampling technique was used. The effect of these positions on NST parameters among antenatal mothers was measured. Analysis of baseline characteristics was done through the descriptive statistics and correlation was done by ANOVA. There were statistically significant differences in No. of accelerations (p=0.021 < 0.05) between the three groups. The selected maternal positions are effective on fetal parameters of non stress test in antenatal mothers of 32-40 weeks of gestation. According to the correlation Left lateral and semi fowlers positions are effective than supine position for non stress test. There were arithmetical significant differences in Number of accelerations (p=0.021 < 0.05) between the three groups. Semi fowler’s position was identified as superior position for conducting NST.
