In addition to sideward bendings of the head, complex and generalized movements occur at the beginning of the fetal stage, with movements and startles that involve the whole body. [11] Movement of hands, hips and knees have been observed at nine weeks, [12] stretches and yawns at ten weeks, [13] and isolated limb movements beginning shortly ...
The fetal akinesia in amyoplasia is thought to be caused by various maternal and fetal abnormalities. In some cases, the mother's uterus does not allow for adequate fetal movement because of a lack of amniotic fluid, known as oligohydramnios, or an abnormal shape to the uterus, called a bicornuate uterus.
Postterm pregnancy is when a woman has not yet delivered her baby after 42 weeks of gestation, two weeks beyond the typical 40-week duration of pregnancy. [1] Postmature births carry risks for both the mother and the baby, including fetal malnutrition, meconium aspiration syndrome , and stillbirths . [ 2 ]
As the fetal load increases, women tend to arch their lower backs, specifically in the lumbar region of their vertebral column to maintain postural stability and balance. The arching of the lumbar region is known as lumbar lordosis , which recovers the center of mass into a stable position by reducing hip torque .
A woman's uterine muscles, rather than her abdominal muscles, are first to sense fetal motion. Therefore, her body weight usually does not have a substantial effect on when movements are initially perceived. Women who have previously given birth have more relaxed uterine muscles which are more sensitive to fetal motion during subsequent ...
A woman pregnant for the first time (nulliparous) typically feels fetal movements at about 21 weeks, whereas a woman who has given birth before will typically feel movements by 20 weeks. [13] By the end of the fifth month, the fetus is about 20 cm (8 in) long.

These movements include engagement, descent, flexion, internal rotation, extension, external rotation, and expulsion. Engagement is the first movement of labor where the first part of the head enters the pelvic inlet. Descent refers to the deeper movement of the head through the pelvic inlet with the widest diameter of the infant's head.
