Normal Development Review Flashcards
Normal developmental milestones
Head control - 4 mo Rolling - 6-8 mo Sitting - 8 mo Creeping - 9 mo Cruising - 10 mo Walking - 12 mo
2 year old motor milestones
Reciprocal arm swing, heel strike during gait, run with flight phase, SLS 1-3 sec, throw a small ball, up stairs reciprocally, goes down stairs “marking time”
3-5 year old motor milestones
Going up/down stairs reciprocally (3), hopping four times (4), galloping (5), skipping (6)
5-6 year old motor milestones
SLS 8-10 sec (5), skip with alternating feet (5), SLS 10 sec eyes closed (6), riding a bike (6)
Phases of prone progression
Prone, head lift & reach, head lift & reach with alternating arms, prop up on extended arms, extended arm reaching, alternating extended arm reaching, crawling, forward progression, double arm pulling, alternate crawling, quadruped sitting, standing
Suck-Swallow primitive reflex
Instinctively suck anything that touches roof of mouth
Onset = 28 week gestation
Integration = 2-5 mo
Rooting primitive reflex
Assists in breastfeeding. Turning of head toward the object that strokes the cheek/mouth
Onset = 28 weeks gestation
Integration = 3 mo
Flexor withdrawal primitive reflex
Pulls feet away after being touched
Onset = 28 weeks gestation
Integration = 1-2 mo
Crossed extensor primitive reflex
After being touched the opposite leg flexes and then extends.
Onset = 28 weeks gestation
Integration = 1-2 mo
Moro primitive reflex
Response to loss of balance. Arms/legs will splay out in extension and then re-flex
Onset = 28 weeks gestation
Integration = 4-6 mo
Positive support primitive reflex
Feet on surface, then push off that surface and straighten legs
Onset = 35 weeks gestation
Integration = 1-2 mo
Asymmetric Tonic Neck primitive reflex
Turn head to right, right arm straightens, left arm flexes (and vice versa)
Onset = birth
Integration = 4-6 mo
Palmar grasp primitive reflex
Stroke the palm, hand flexes
Onset = birth
Integration = 9 mo
Symmetrical Tonic Neck primitive reflex
Child is in prone, extend elbows and head extends, flex neck and elbows bend
Onset = 4-6 mo
Integration = 8-12 mo
Reflexes definition
Stereotypic, involuntary responses to sensory stimuli used to access developmental function and nervous system integrity
