Motor development (Quiz 1) info Flashcards
Definition of gestational age
- 1st day of last menstrual period to day of delivery
-full term weeks
39 weeks- 40 weeks
- early term weeks
- 37 weeks - 38 weeks
premature range
- <37 weeks
What is the corrected age
- 40 weeks - weeks premature
neonate range
(newborn) 0-28
infant ranges
- 0-12 months
toddler ranges
1-3 years
Primitive Reflexes
asymmetrical tonic neck reflex (ANTR)
- appears at 20 wks gestation
- integrates at 4-5 months
- stimulus: turning of head
- response: facial arm extends and abducts, occipital arm flexes and abducts
Primitive Reflexes
Rooting
- appears at 28 weeks gestation
- integrates at 3 months
- stimulus: touch to perioral area of hungry infant
- response: turns head and lips towards stimulus
Primitive reflexes
Suck- Swallow
- appears at 28-34 weeks gestation
- integrates at 5 months
- stimulus: touch to lips and inside of mouth for suckling and liquid for swallowing
- response: rhythmic excursions of jaw; tongue rides up and down with the jaw; followed by swallow
Primitive reflexes
Palmar grasp
- appears at 28 weeks gestation
- integrates at 4-7 months
- Stimulus: pressure on palm of the hand
- Response: flexion of fingers
Primitive reflexes
plantar grasp
- appears at 28 weeks of gestation
- integrates at 9 months
- stimulus: supported standing on feet or pressure to sole of the foot just distal to metatarsal heads
- response: flexion of toes
Primitive reflexes
Galant (trunk incurvation)
- appears at 28 weeks of gestation
- integrates at 3 months, inconsistent
- stimulus: in prone, stroke paravertebral skin
- response: lateral of curvature
Primitive reflexes
Moro
- appears at 28 weeks of gestation
- integrates at 3-5 months
- stimulus: head drop backwards (loud noise for startle)
- response: abduction and extension of arms, splaying of fingers, may be followed by arm flexion and adduction
Primitive Reflexes
automatic walking/ stepping reflex
- appears at 37 weeks of gestation
- integrates at 3-4 months
- stimulus: hold upright with feet on support
- response: high stepping movements with regular rhythm
Primitive reflexes
Symmetrical tonic neck (STNR)
- appears at 4-6 months post full term delivery
- integrates at 8-12 months
- stimulus: flexion or extension of the head
- Response: with head flexion, arms flex and hip extend, with head extension arms extend and hips flex
Neonate and first month movement in supine
- wide movements of arms
- recoil with passive extension
- rhythmic kicking when active
neonate and first month movement prone
- head to side with weight on cheek: may briefly lift head
- elbows behind shoulders
neonate and first month pull to sit
-total head lag
neonate and first month supported stand
- automatic walking
neonate and first month atypical movements
- strong extension, minimal physiological flexion
- no flexor recoil
- marked hypotonia
- no lower extremity kicking
- does not accept weight in standing
- no recognition of changing head position with pull to sit
2nd month general
- period of greatest asymmetry due to strong ATNR
- more disorganized than 1 month old
- not a good time to evaluate motor progress
2nd month supine movement
- visually tracking
- increased shoulder mobility
- variety of LE kicking movements
