4-6 months
STNR integration
8-12 months
STNR stimulus
Place in crawling position and flex the head
Place in crawling position and extend the head
STNR response
Head extension: arms extend and hips/knees flex
Head flexion: arms flex and legs instead
STNR functional importance
Facilitates quadruped position in preparation for crawling, breaks up total body extension
What happens if STNR is not integrated
Baby will resist movement to sit up because neck flexion will result in hip/leg extension, poor muscle tone and posture
