Development of Motor Control

Elements of Fine Motor Development:

• Bilateral motor control

• Reflex integration

• Reach/grasp

• Object manipulation

• Tool/implement usage

Bilateral GROSS motor integration controls:

• Lead assist hand roles

• Ipsilateral movement of limbs

• Control of muscles of the trunk

• Contralateral movement of limbs

Bilateral FINE motor integration controls:

• Contralateral movement of limbs

• Crude two handed movements

• One handed movements

• Lead assist hand roles

Bilateral motor control integration:

Baby asymmetrical and NOT bilateral in arm movements

• 3-10 months

• 10-12 months

• birth to 3 months

• 15-18 months

Bilateral motor control integration:

baby symmetrical and bilateral in arm movements

• 3-10 months

• birth to 3 months

• 10-12 months

• 15-18 months

Bilateral motor control integration:

unilateral hand movements crude

• birth to 3 months

• 3-10 months

• 10-12 months

• 15-18 months

Bilateral motor control integration:

lead assist hand patterns

• birth to 3 months

• 10-12 months

• 3-10 months

• 15-18 months

movement and stabilization of the arm and hand for the purpose of contacting an object

attainment of an object with the hand

Steps of reaching and grasping:

• power grasp

• batting

• grasp goes from reflexive to voluntary

• release an object
