Fetal activity during midgestation (M age=19.8 weeks) was studied in response to vibratory stimulation of the mother's abdomen (at the height of the fetal head), foot massage, hand massage, or control condition (no stimulation). Consistent with previous research conducted during midgestation, the fetuses of mothers who received two trials of 3-sec, 60-Hz vibratory stimulation did not show changes in movement. In contrast, the fetuses of mothers who received a 3-min foot massage showed greater movement than the control fetuses. However, stimulating the mother's hand (another highly innervated area) did not increase fetal activity. By late gestation (M age=35.4 weeks), vibratory stimulation resulted in increased fetal activity. These findings replicate previous research indicating that vibratory stimulation to the mother's abdomen does not elicit fetal activity until later in gestation. Furthermore, our findings indicate that stimulating the mothers' feet, but not the hands, can evoke fetal activity in midgestation.
研究了孕中期（平均年龄 = 19.8周）胎儿对母亲腹部（胎儿头部高度）的振动刺激、足部按摩、手部按摩或对照条件（无刺激）的反应。与之前在孕中期进行的研究一致，接受两次3秒、60赫兹振动刺激试验的母亲的胎儿运动没有变化。相比之下，接受3分钟足部按摩的母亲的胎儿比对照胎儿的运动更多。然而，刺激母亲的手部（另一个神经高度分布的区域）并没有增加胎儿活动。到妊娠晚期（平均年龄 = 35.4周），振动刺激导致胎儿活动增加。这些发现重复了之前的研究，表明对母亲腹部的振动刺激直到妊娠后期才会引起胎儿活动。此外，我们的研究结果表明，在孕中期刺激母亲的足部而非手部可以诱发胎儿活动。
