Fetal activity following stimulation of the mother's abdomen, feet, and hands


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 thefetal 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.
