Unit 1 Flashcards
What is motor control?
-the control and organization of processes underlying movement; that is already aquired
What is motor learning?
-the acquisition of skill through practice and experience; also includes the modification of movement
What is motor development?
-the age related process to changes in motor behavrio; the ability to perform certain activities based on normal developement
What position do most infants start out in?
-Physiological flexion
What do infants gain first, antigravity extension or flexion?
-Antigravity extension
Which direction to most infants learn to roll first?
-prone to supine, then supine to prone
In what direction does motor control develop?
-head to toes
What develops first, mobility or stability?
-mobility; this is why infants are able to move arms and legs before they are able to support their head
What are the 3 phases of stability development?
-Structural stability, positional stability, Internal stability
What is structural stability due to?
-tissue tightness; ex: physiological flexion
What is positional stability?
-the use of body parts to gain a larger base of supprt
What is internal stability?
-include righting reactions and equilibrium
As an infant develops posture, what happens to the base of support and ROM?
-BOS decreases; ROM increases
What is needed if the child does not develop internal stability?
-external stability
What is controlled mobility?
-the utilization of mobility and stability for functional tasks
What is skill?
-the use of controlled mobility, mobility, and stability to interact with an object while maintaining a position
How does posture present early in infancy?
-Assymetrically
When does posture become more symmetrical?
-about 4 months
What develops after symetrical posture/movement?
-controlled assymetry
What type of contractures are normal in infants?
-Flexion contractures
How Should posture present in infants?
-flexion like in womb, hands fisted, head in midline and the child should be visually aware
If an infants hands are too tightly fisted, what might this indicate?
-A nuerologic impairment
What should a child be able to do with their head in early infancy?
-move it side to side to clear their airway
A baby before before what week of gestation is considered premature?
-37 weeks
How will a premature infants posture differ from those born at normal gestation?
-They show decreased physiological flexion, and low muscle tone
