What is the time at which stepping reflex disappears?
100
Hold child upright and tilt laterally
What is the one way to test righting responses?
100
curve trunk toward side of touch
What is Galant reflex?
100
vestibular, optical, somatosensory
What are the sensory systems contributing to postural responses?
200
elongation on the weightbearing side
What is trunk response to weight shift?
200
Sensory responses guide movement
What is role of sensory feedback with movement
200
child brings head back to midline
What is optimal response to testing of head righting?
200
Fingers curl in response to touch
What is palmar grasp?
200
auditory and vestibular
What sensory systems underlie Moro and startle responses?
300
align body with head position
What is neck on body righting reaction?
300
Place child on surface, shift weight and observe responses
What is one way to test sitting equilibrium?
300
arm and leg tend to extend on face side and arm and leg tend to flex on the skull side
What is ATNR?
300
visual and vestibular
What sensory systems are described with righting responses?
400
6 months
What is age by which and infant develops prone equilibrium reactions?
400
Sensation guides movement
What is the role of sensory feedback with infant motor learning?
400
7 months
What is the earliest age to test sitting equilibrium?
400
legs/arms abduct and extend, preparing for weight bearing
What is parachute response
400
tactile
What is the sensory system that underlies flexor withdrawal?
500
Body rotates to align shoulder and pelvis
What is derotation?
500
Infants do not generalize learning - have to learn each movement and practice (A LOT!). For example, crawling up an incline does not generalize to walking up an incline.
What is the reason infants have to practice motor actions so often?
500
Place infant supine on dynamic surface (ball or rocker board), shift weight and observe responses
What is one way to test supine equilibrium?
500
arms abduct and adduct to midline
What is Moro/startle?
500
vestibular
What is the sensory system that gives us information about body position relative to gravity and acceleration/deceleration?
