Pediatric Physiotherapy: Typical motor development · Principles of Motor Development

How babies' movement develops in a predictable order but at varying ages, the theories that explain it, and when variation becomes a warning sign.

For learning, not medical advice: for your own health, ask a doctor or another qualified professional.

Try 3 questions

1. A baby controls its head first, then sits, then stands. Which principle of motor development does this order illustrate?

  1. Cephalocaudal progression
  2. Ulnar-to-radial progression
  3. Proximodistal progression
Show the answer

Answer: Cephalocaudal progression

Cephalocaudal means head to tail: control of the head and upper body develops before control of the trunk and legs.

2. An infant steadies the shoulder and swings the whole arm toward a toy long before using the fingers precisely. Which principle explains this?

  1. Ulnar-to-radial progression
  2. Cephalocaudal progression
  3. Proximodistal progression
Show the answer

Answer: Proximodistal progression

Proximodistal means from the body's center outward: control near the trunk, such as the shoulder, comes before control of the hands and fingers.

3. Across typically developing children, which aspect of early motor development is the most consistent?

  1. The time between two milestones
  2. The exact age of each milestone
  3. The general order of milestones
Show the answer

Answer: The general order of milestones

The sequence (head control, sitting, standing, walking) is broadly shared, while the age at which each milestone appears varies widely between healthy children.
