“…30,34 With MR imaging providing a fuller appreciation of the intrauterine environment, we observed that the fetal posture appears to facilitate the adduction of the arms toward the midline and the flexion of the hands toward the face across the age range studied (Fig 3A,-B). It is difficult to quantify the effect that the shape of the uterus has on determining this posture, though coronal sections through the fetal body show that from GA 20 weeks, there is negligible amniotic fluid on its lateral aspects (Fig 3A), with collections located mostly anterior and posterior to the fetus (Fig 3B).…”

BACKGROUND AND PURPOSE:The assessment of motor function is an essential component of neurologic examinations, which imaging studies have extended to the fetus. US assessment is hampered by a limited FOV, whereas MR imaging has the potential to be an alternative. Our objectives were to optimize a cine MR imaging sequence for capturing fetal movements and to perform a pilot analysis of the relationship between the frequency of movements and uterine spatial constrictions in healthy fetuses.

“…In contrast to previous studies on fetal laterality (Ververs, van Gelder-Hasker, de Vries, Hopkins & van Geijn 1998;Hepper, Shahidullah & White 1991), our coding scheme used continuous recording of fetal movements. Ten minutes of segments of the 60 scans, in which the fetal face as well as a hand were visible was selected and coded frame by frame and analysed in terms of frequency of occurrence of self-touch.…”

“…These researchers coded left and right arm movements and did not detect any differences in the frequency of right or left movements. Ververs, van Gelder-Hasker, de Vries, Hopkins & van Geijn, 1998) videotaped 2-D scans of 10 fetuses from 12-38 weeks gestation every 4 weeks. Scoring the movements of one fetal arm every 30 seconds they did not find any significant differences between frequencies of right or left arm movements.…”

This longitudinal observational study investigated whether foetuses change their hand preference with gestational age, and also examined the effects of maternal stress on lateralized foetal self-touch. Following ethical approval, fifteen healthy foetuses (eight girls and seven boys) were scanned four times from 24 to 36 weeks gestation. Self-touch behaviours which resulted in a touch of the foetal face/head were coded in 60 scans for 10 min and analysed in terms of frequency of the foetuses using left and right hands to touch their face. The joint effects of foetal age, stress and sex on laterality were assessed. We modelled the proportion of right self-touches for each foetal scan using a generalized linear mixed model, taking account of the repeated measures design. There was substantial variability in hand preference between foetuses. However, there was no significant increase in the proportion of right-handed touches with foetal age. No sex differences in handedness were identified. However, maternally reported stress level was significantly positively related to foetal left-handed self-touches (odds ratio 0.915; p < .0001). This longitudinal study provides important new insights into the effect of recent maternal stress on foetal predominant hand use during self-touch.

“…Furthermore, fetal facial touch does not seem impeded with increasing gestational age given that research indicates that fetuses at 24 weeks gestational age have their elbows flexed 93% of the time observed (Ververs, Van Gelder-Hasker, De Vries, Hopkins, Van Geijn, 1998), increasing further at 36 weeks. Hence, elbow flexion which might be considered to be conducive to face touch is not related to fetal age.…”
