Suck swallow 28 weeks to 2-5 months Finger inside mouth results in strong rhythmic sucking For feeding
Traction 28 weeks to 2-5 months grasp infants forearm and pull to sit results in complete flexion of UE's enhances momentary reflexive grasp
Moro 28 weeks gestation to 4-6 months rapidly drop infants head backward results in arm extension and abduction and hand opening initially and then arm flexion and adduction facilitates ability to depart from dominant flexor posture--protective response
Plantar grasp 28 weeks to 9 months pressure to ball of foot results in toe flexion increases tactile input to sole of foot
Galant 32 weeks to 2 months prone in air, tap the spine from shoulder to buttocks results in lateral trunk flexion and wrinkling of skin on stimulating side lateral trunk movements for trunk stabilization
Asymmetric tonic neck reflex 37 weeks to 4-6 months rotate infants head and hold for 5 seconds results in extension of extremities on face side, flexion on skull side promote visual hand regard
Palmar grasp 37 weeks gestation to 4-6 months finger in palm results in finger flexion and reflexive grasp increases tactile input to hand
Tonic labyrinthine supine 37 weeks to 6 months infant in supine results in increased extensor tone
Tonic labyrinthine prone 37 weeks to 6 months infant in prone results in increased flexor tone
Labyrinthine optical head righting birth to 2 months to persists suspend vertically and tilt slowly to the side, forward, or backward results in upright positioning of the head orients head in space, maintains face vertical
Landau 3 months to 1-2 years hoironztal prone in air results in complete extension of head, trunk, extremities facilitates prone extension and breaks up flexor dominance
Symmetric tonic neck reflex 4 months to 8-12 months crawling position and extend head results in flexion of hips and knees breaks up extensor tone and facilitates static quad position
Neck righting 4 months to 5 years supine and fully turn head to one side results in log rolling of entire body to maintain alignment iwth head initiates rolling (first ambulation effort)
Body right on body 4 months to 5 years infant in supine and flex one hip and knee toward chest and hold briefly results in segmental rolling of upper trunk facilitates trunk and spinal rotation
Protective extension downward 4 months persists rapidly lower infant while suspended vertically results in extension of LEs accurate placement of LE's
Protective extension forward 6 to 9 months and persists tip infant foward while vertically suspended results in extension of UE, hand opening, and neck extension accurate placement of UE anticipation of upporting surface to prevent fall
Protective extension sideward 7 months and persists quickly and firmly tip infant off balance to the side while sitting results in arm extension and abduction to the side
Protective extension backwrard 9-1o months and persists quickly and firmly tip infant off balance backward results in backward arm extension or arm extension to one side spinal rotation
Prone tilting 5 months and persists prone, slowly raise one side of the supporting surface results in curving of the spine toward the raised side and abduction/extension of arms and legs postural adjustmens and maintains equilibrium
Supine tilting and sitting tilting 7 months and persists supine or sitting, raise one side of supporting surface results in curving of spine toward raised side and abduction/extension of arms and legs
quadruped tilting 9 to 12 months and persists four point, raise one side of the surface results in curving of spine toward raised side, abduction/extension of arms and legs
Stand tilting 12-21 months and persists standing, raise one side of surface results in curving of spine towards raised side
