[The investigations on the effect of daily activity on the uterine contraction during pregnancy]. 1984

R Araki

The present paper is characterized by its uniqueness in that uterine contractions were studied in pregnant women in their own home while engaged in their daily activities. The author, using conventional and newly devised small external tocodynamometers , investigated how daily activities affected uterine contraction during pregnancy and the results are as follows. In normal pregnancy, uterine contractions with a duration of 31-180 sec. were found 1.3-1.5 times per 30 min. in the 6-7th gestational months and 4.8 times in the 10th month. Circadian changes varied according to the number of gestational months. Uterine contractions were easily enhanced by shopping, bath-taking, train-riding, swimming, sexual intercourse, etc. CTG recordings of how they were actually enhanced are shown with statistical data and explanations. Contractions were easily increased by housework activities in patients with threatened preterm labor. When uterine contractions were abnormally strong during pregnancy, the cervix was found to be ripened even before term.
