[An evaluation of fetal movement during non stress testing (author's transl)].

The measuring methods of fetal rolling movements, which are very important diagnostic informations at the case of Non Stress Test, are analysed. In normal pregnant women (from 29 to 40 gestational weeks), the observation of fetal head and trunk rolling movements by real-time B-scan, and maternal perception of fetal movements are simultaneously recorded in analog data recorder. Analysing these recorded data, we found that 76.7% of fetal rolling movements could be detected by observation of head rolling movements only, and 72.4% with trunk observation only. But maternal perception could find only 28.5% of fetal rolling movements. These results and analysis may suggest us that, if only one machine is available, the observation of fetal head rolling movements by real-time B-scan is the most effective method for the analysis if fetal rolling movements on NST.
