| Research Abstract |
We developed a small capacitive acceleration sensor of fetal movement with high output power, FMAM (Fetal Movement Acceleration Measurement)recorder and an automatic analysis system of fetal movement. The recorder (290g, 77mm X 27mm X 140mm) consists of two sensors (one for fetal movement ; one for maternal movement), a biological amplifier, and an SD card drive. We can record fetal movement during continuous 40 hours.
The subjects were nine normal pregnant women (29-39 yr) who gave written informed consent. They recorded fetal movement once every four weeks from 20 to 36 gestation weeks. The number of fetal movement during maternal sleep showed weekly variation with individual differences. In the automatic analysis system of fetal movement, there were a few problems in artifacts coming from the mother, especially her respiration. We could record fetal movement of two pregnant women with high risks who had experienced stillbirth. The number of their fetal movement distributed within a rage of fetal movement of the pregnant women with low risks. When they saw analysis figures of their fetal movement, they felt safe of their fetal well-being.
The pregnant women were able to easily record fetal movement using the FMAM recorder at night by themselves. The FMAM recorder is promising for a long term monitoring of fetal movement. It will be necessary to collect more data on normal pregnant subjects and to improve the system of analysis to exclude maternal artifacts.
