Stages of Motor Development Manipulative Flashcards
Initial Underhand Rolling
straddle stance, ball held w/ hands on side (palms facing each other), acute bend at the sides, backwards pendulum motion, eyes monitor the ball, forward swing and trunk lift to release ball
Elementary Underhand Rolling
stride stance, larger ball held w/ 1 hand on top and bottom (smaller ball w/ 1 hand), backward arm swing w/out weight transfer to rear, limited knee bend, forward swing w/ limited follow through, ball released between knee and waist level eyes alternate monitoring target and ball
Mature Underhand Rolling
contralateral step, ball in hand corresponding to trailing leg, slight hip rotation and trunk lean forward, pronounced knee bend, forward swing w/ weight transferred from back to front foot, release at knee level or below, eyes on target throughout
Initial Underhand throwing
stationary stance, ball is held w/ hands on side, palms facing each other, limited swing backward, eyes monitor the ball, forward swing and trunk lift to release ball
Elementary Underhand Throwing
Ipsilateral step on stride stance, ball is held w/ 1 hand, backward swing w/out weight transfer to rear, forward swing w/ limited follow through, ball released between knee and waist level or above chest level, eyes alternate target and waist level
Mature Underhand Throwing
Contralateral step, ball is held in hand corresponding to trail leg, forward swing w/ weight transfer from back to front foot, release at waist level, follow through, eyes on target throughout
Initial Overhand Throwing
ball is thrown in a chop like motion, arm bend at elbow for a vertical windup, feet are stationary during throw, no spinal or hip rotation
Elementary 2 Overhand throwing
ball is thrown in a slingshot motion, windup is horizontal, block rotation as spine rotates away from the line of flight, arms follow through across body
Elementary 3 Overhand Throwing
throws and steps using same side arm and leg, high windup, feet cross during the step forward, little spinal rotation, follow through across body
Elementary 4 Overhand Throwing
throw and step w/ opposite arm and leg, high windup, little spinal rotation, follow through across body
Mature Overhand Throwing
Throw and steps w/ opposite arm and leg, downward arc on the windup, body rotation is segmented, arm and leg follow through
Initial Striking
Chop strike, feet stationary, no trunk rotation, elbows fully flexed force comes from extension of flexed joints in a downward plane
Elementary 2 Striking
Horizontal push or swing, feet are stationary or maybe a step, weight shift to front foot before striking, combined trunk and hip rotation (block rotation)
Elementary 3 Striking
ipsilateral step, back foot steps across, diagonal downward swing, strike in oblique plane
Mature Striking
contralateral step, segmented body rotation, wrist rollover, on follows through, weight shift to back foot as implement moves backwards, striking in a long full arc in horizontal plane, weight shifts to front foot on contact
