Sensorimotor Skill Development Flashcards
GM prone 0-2 mo (8)
turns head side to side; lifts head momentarily; bends hips with bottom in air; lifts head and sustains midline; rotates head freely when up; able to bear weight on forearms; able to tuck chin and gaze at hands in forearm prop; attempts to shift weight on forearms, resulting in shoulder collapse
GM prone 5-6 mo (5)
shifts weight on forearms and reaches forward; bears weight and shifts weight on extended arms; legs are closer together and thighs rolls inward toward natural alignment; hips are flat on surface; equilibrium reactions are present
GM prone 5-8 mo (1)
airplane posturing in prone position (chest/thighs lift off surface)
GM prone 7-8 mo (2)
pivots in prone position; moves to prone position to sit
GM prone 9 mo (1)
begins to dislike prone position
GM supine 0-3 mo (2)
head held to one side; able to turn head side to side
GM supine 3-4 mo (4)
holds head in midline; chin is tucked and neck lengthens in back; legs come together; lower back flattens against the floor
GM supine 4-5 mo (2)
head lag is gone when pulled to a sitting position; hands are together in space
GM supine 5-6 mo (5)
lifts head independently; brings feet to mouth; brings hand to feet; able to reach for toy with one or both hands; hands are predominantly open
GM supine 7-8 mo (1)
equilibrium reactions are present
GM rolling 3-4 mo (2)
rolls from prone position to side accidentally because of poor control of weight shift; rolls from supine to side
GM rolling 5-6 mo (3)
rolls from prone to supine; rolls from supine to side with R and L leg performing independent movements; rolls from supine to prone with R and L leg performing independent movements
GM rolling 6-14 mo (1)
rolls segmentally with roll initiated by the head, shoulder, or hips
GM creeping 7 mo
crawls forward on belly
GM creeping 7-10 mo
reciprocal creep
GM creeping 10-11 mo
creeps on hands and feet
GM creeping 11-12 mo
creeps well
GM sitting 0-3 mo (7)
*held in sitting
head bobs; back is rounded; hips apart/turned out/bent; head steady; chin tucks (able to gaze at floor); sits w/ less support; hips bent and shoulders in front of hips
GM sitting 5-6 mo (7)
supports self in sitting; sits alone momentarily; increased extension in back; sits by propping forward on arms; wide base/legs bent; periodic use of “high guard” position; protective responses present when falling to the front
GM sitting 5-10 mo (2)
sits alone steadily (initially w/ wide BOS); able to play with toys in sitting position
GM sitting 6-11 mo (1)
gets to sitting position from prone
GM sitting 7-8 mo (3)
equilibrium reactions present; able to rotate UB while LB remains stationary; protective responses are present when falling to the side
GM sitting 8-10 mo (4)
sits well w/o support; legs closer/full upright w/ knees straight; increased variety of sitting positions (w-sit and legs to side); difficult FM task = return to wide BOS
GM sitting 9-18 mo (1)
rises from supine by first rolling to prone then pushing up to 4-point position
GM siting 10-12 mo (2)
protective extension back (first straight then bent elbows); able to move in and out of sitting to other positions
GM sitting 11-12 mo (2)
trunk control and equilibrium responses are fully developed in sitting; further increase in variety of positions possible
GM sitting 11-24+ mo (1)
rises from supine by first rolling to side then pushing up to sit
GM standing 0-3 mo (1)
when held in standing position, takes some weight on legs
GM standing 2-3 mo (1)
when held in standing, legs may give way
GM standing 3-4 mo (4)
bears some weight on legs but must be held proximally; head is up in midline/no chin tuck; pelvis and hips are behind shoulders; legs are apart and turned outward
GM standing 5-10 mo (1)
stands while holding onto furniture
GM standing 5-6 mo (4)
increased capability to bear weight; decreased support needed (may be held by arms or hands); legs still spread apart/turned out; bounces in standing position
GM standing 6-12 mo (1)
pulls to standing at furniture
GM standing 8-9 mo (3)
rotates trunk over LE; LE more active in pulling to stand; pulls to stand by kneeling, then half kneeling
GM standing 9-13 mo (2)
pulls to standing with legs only (no longer needs arms); stands alone momentarily
GM standing 12 mo (1)
equilibrium reactions present in standing
GM walking 8 mo (1)
cruises sideways
GM walking 8-18 mo (1)
walks w/ two hands held
GM walking 9-10 mo (1)
cruises around furniture, turning slightly in intended direction
GM walking 9-17 mo (1)
takes independent steps, falls easily
