A fetal akinesia sequence is an event that can occur with a lack of fetal movement (fetal akinesia). This results in:
The estimated prevalence is at ~1 in 3000 births.
Associations
In utero fetal movement is considered essential for normal fetal growth. In fetal akinesia sequence, intrauterine immobility is thought to be triggered by a number of factors which include:
-
central or peripheral neuropathic processes
-
congenital myopathies
intrauterine exposure to immobilizing substances
connective tissue or cutaneous conditions (restrictive dermatopathy) limiting fetal movement
-
external movement limiting factors
