Natalie had random hand movements when she was 2 months old. When she was 6 months old, she would grab a block with her whole hand. Now at the age of 10 months, she can grasp the same block with her thumb and forefinger. This sequence of growth in her hand and finger movements is occurring according to the pattern.

Proximodistal Pattern

Explanation:

The tendency for more general functions of limbs to develop before more specific or fine motor skills.Proximodistal is coined from two Latin words which are Proxim which means close and dis which means away from due to the fact that the trend essentially describes a path from the center outward.

Natalie random hand movement at the age of two months without proper dexterity and grabbing a whole block at the age of six with a proper coordination of the muscles clearly illustrates Proximodistal pattern and comfirms to it's defination.

proximodistal pattern

Explanation: Natalie's pattern of development from the hands to palm and then fingers follows the proximodistal pattern which is described as a running from the center of the body out towards the distal ends of appendages. As such, the proximodistal pattern development occurs from the centre of the body in an outward direction towards the extremities. Infants usually will first learn to move their core, then their arms and legs because the spine develops first in the womb, followed by the extremities and finally fingers and toes.
