title: A comparison between maternal, tocodynamometric, and real-time ultrasonographic assessments of fetal movement.
abstract: Fetal movements were simultaneously studied with maternal perception, tocodynamometry, and real-time ultrasonography. A comparison between these three modalities demonstrated good agreement. The percentage of agreement improved with increasing duration of fetal movements. For fetal movements lasting longer than 3 seconds, the agreement between ultrasonography and tocodynamometry was 95.6%. These findings suggest that tocodynamometry is a sensitive method for studying fetal movements.
