对人类胎动自发波动的频谱分析显示，其频率在每分钟 0.24 至 0.90 周期之间存在强烈振荡，远高于胎儿和新生儿安静和活跃状态的周期性交替。还检测到频率高达每分钟 2.88 周期的振荡，但它们通常要弱得多。胎儿运动频谱中的突出峰值位于最近报道的新生儿运动节律的频率范围内，并表明存在控制自发运动输出的循环过程，该输出每分钟振荡近一个周期并开始在子宫内发挥作用。
Spectral analysis of spontaneous fluctuations in human fetal movement revealed strong oscillations at frequencies between 0.24 and 0.90 cycle per minute, which are much higher than those of the cyclic alternation of quiet and active states in the fetus and neonate. Oscillations at frequencies up to 2.88 cycles per minute were also detected, but they were usually much weaker. The prominent peaks in the fetal movement spectra are in the frequency range of recently reported neonatal motor rhythms, and indicate the existence of a cyclic process controlling spontaneous motor output that oscillates near one cycle per minute and begins to function in utero.
