Child Motion Assessment – 7-Year-Old Pitcher
1. Posture & Setup
• The child sets up with good stance width and balance.
• Shoulders are slightly elevated, indicating early tension before movement.
• Glove and throwing hand are positioned correctly, but lack complete rotational preparation.
2. Wind-Up & Leg Lift
• During the knee lift, there is good height, but the torso leans slightly back rather than keeping a centered axis.
• The standing leg is stable but shows signs of “locking,” reducing flexibility for rotational transfer.
• Independence between the standing leg and the lifted leg is developing, but balance is still prioritized over freedom of motion.
3. Rotation & Torque
• The throwing sequence uses mainly arm speed rather than full trunk rotation.
• Hips open after the shoulders, showing a delayed chain reaction.
• This reduces efficiency and could later increase strain on the shoulder and elbow.
4. Stride & Ground Force
• Stride length is appropriate, but foot placement lands slightly closed, limiting hip clearance.
• Push from the back leg lacks complete midline transfer, so power is not fully coming from the pelvis.
5. Follow-Through
• The arm decelerates well, but the spine remains stiff, showing reduced “whip” through the torso.
• Glove arm collapses inward rather than stabilizing, decreasing rotational balance.
Summary:
This child demonstrates excellent effort and coordination for his age, but movement is still dominated by arm action instead of full-body sequencing. The key developmental focus should be:
• Rotation through the hips and torso rather than over-reliance on the arm.
• Independent standing leg control to allow the free leg to move naturally.
• Balanced follow-through with trunk and glove arm integration.
