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.
