Researchers from Imperial College London suggest that babies’ movements during pregnancy are critical for normal development of bones and joints
The researchers used a cine-MRI technique to calculate how the force of a baby’s kicks and the stress on their bones and joints in the womb change from week 20 to week 35. They found that from week 20 to week 30 the strength of babies kicks almost doubled. While the strength of the kicks dropped from week 30 to 35, the stresses and strains on the skeleton increased steadily from week 20 to week 35. This stress on the skeleton is critical for normal bone development.
