Introduction
Most fetuses with Down syndrome exhibit fetal movements, although a few may have weak or no noticeable fetal movements due to severe developmental abnormalities. Although most fetuses with Down syndrome have chromosomal abnormalities, their own development is not severely affected, and limbs and other organs can function normally; therefore, fetal movements are present. The pattern and intensity of fetal movements are not significantly different from those of normal fetuses, and mothers can perceive clear fetal activity.

Under normal circumstances, most fetuses with Down syndrome will have fetal movements, although a few may have weak or no obvious fetal movements due to severe developmental abnormalities. If any abnormalities are noticed, timely medical consultation is recommended. Detailed explanation is as follows:

Although most Down syndrome fetuses have chromosomal abnormalities, their physical development is often not severely affected, and their limbs and other organs can move normally. Therefore, these fetuses usually have fetal movements, with patterns and intensity similar to those of normal fetuses, and expectant mothers can clearly perceive their movements.

However, some fetuses with Down syndrome may have serious congenital malformations, such as underdeveloped hearts or abnormal limb development, which can weaken the fetus's mobility, resulting in weak or infrequent fetal movements or even no obvious movements. Such conditions can be detected through ultrasound examinations.

During pregnancy, regular monitoring of fetal movement and timely prenatal screening for Down syndrome are necessary. If abnormal fetal movements or screening results are observed, further diagnostic tests should be conducted promptly to confirm the situation.
