Premature Milestones

Question 1

27-28 weeks

Answer 1

generalized HYPOTONIA
full ROM without resistance
immediately fatigued with visual stimulus
flexor withdrawal onset

Question 2

29 weeks

Answer 2

extreme head lag
movement of LE>UE
attempts to right head anteriorly in supported sitting
occasional eye opening (wake cycles more frequent)

Question 3

30-31 weeks

Answer 3

INCREASED FLEXOR TONE LE>UE
recoil LE>UE
rights head anteriorly/posteriorly momentarily (anticipatory head righting)
tracking from midline horizontally

Question 4

32 weeks

Answer 4

maintains head in alignment with supported sitting
MORO REFLEX
hand to mouth
tracks vertically, can focus on stimulus (e.g. face)

Question 5

33-34 weeks

Answer 5

stronger flexion of lower extremities
recoil increases in strength UE/LE
follows/tracks stimulus past midline
frog-like resting posture

Question 6

35 weeks

Answer 6

PHYSIOLOGIC FLEXION
turns head in prone
attempts to maintain head in alignment with pull to sit

Question 7

36 weeks

Answer 7

FLEXOR TONE THROUGHOUT
all primitive reflexes elicited
attempt to maintain head in midline with pull to sit 
pulls into flexion in prone
stepping and placing responses present
