Spontaneous or electrically stimulated activity of the uterus is measured isometrically in vitro by integrating tension against time. Uterine contractions move the operating rod of a potentiometer transducer, the output voltage from which is coupled to an electrical integrator motor and a servo recorder. Several parameters of uterine activity can be expressed in a single measurement, and a record of isometric contractions is obtained simultaneously. Oxytocin can be assayed accurately and the effect of drugs on uterine motility can be measured.
