Fetal movements in multiple pregnancy

Fetal activity in multiple pregnancies, as expressed by maternal daily fetal movement recordings, was compared with that in singleton pregnancies. It was found that the mean fetal activity in 33 cases of twins, six cases of triplets, one case of quadruplets, and one case of quintuplets was generally higher than that obtained during singleton pregnancies. In most cases, fetal movements of triplets, quadruplets, and quintuplets were even higher than the movement of twins.
