Difference between cephalocaudal trends and proximodistal trends
Cephalocaudal trends refer to the development that occurs from the head downward or from the top of the body to the bottom. This means that control and coordination of the head and trunk develop before control and coordination of the arms and legs. This trend can be seen in infants, who gain control over their head and neck muscles before developing control over their limbs.
Proximodistal trends, on the other hand, refer to development that occurs from the center of the body outward or from the body's core to the extremities. This means that control and coordination of the torso develop before control and coordination of the hands and feet. This trend can also be seen in infants, who develop the ability to roll over and sit up before they develop the ability to grasp and manipulate objects with their hands.
In summary, cephalocaudal trends focus on development from the head downward, while proximodistal trends focus on development from the center of the body outward. Both trends play a role in the overall physical development of individuals.
