EVALUATION OF ISOMETRIC EXERCISE TEST AND ROLL-OVER TEST AS METHODS OF PREGNANCY

 ABSTRACT Background: The incidence of pregnancy induced hypertension (PIH) which is one of the three main causes of maternal-neonatal morbidity and mortality is 5-7%, and prediction of this disorder is very important in maternal and neonatal health. Methods: The type of this study is analytical (comparative-prospective) and its purpose is to evaluate the isometric exercise test (lET) and roll-over test (ROT) as methods ofPIH prediction. 116 nulliparaes, with study characteristics, after filling a questionaire and physical exam, underwent ROT, and then lET after 5 minutes, between 28-32 weeks of their pregnancy. The samples are followed up regularly until24 hr after delivery in Mashad university prenatal clinics and hospitals. Statistical analysis was done by SPSS with a: 0.05. Results: As a result, lET has a higher validity than ROT(sensitivity:78.9% vs. 47.4%, p<0.0001, specificity: 94.80 vs. 83.5%,p: 0.007,positivepredictivevalue: 75% vs. 36%,p: 0.0001, negative predictive value: 95.8% vs. 89%, p: 0.046), also validity of IETandROTtogetheris: sensitivity: 85.7%, specificity: 96.3%,PPV: 66.6% andNPV: 98.8%. Conclusion: The validity of lET in this study was shown to be higher than ROT, and by use of a very simple and cost -effective lET, we are able to predict PIH with the highest validity and if possible, use both tests in order to raise validity.
