From head to toe

Proximal to distal

Question 2

Answer 2

6 months

Question 3

Answer 3

Head positioned in either flexion or extension

Head flexed: arms flexed and legs extented
Head extended: arms extended, legs flexed

Question 4

When does STNR integrate and when is it seen?

Answer 4

6 to 8 months when learning to crawl

Integrates 11 months

Question 5

What are 3 things STNR can interfere with?

Answer 5

1. ability to prop on arms in prone
2. positioning in quadruped
3. crawling reciprocally

Question 6
