Physical Development AbilityScore 400–500: next steps

A score in this band is a starting point, not a verdict — it tells us exactly where to begin building your child's strength, balance and confidence in movement.

In short

A Physical Development AbilityScore® in the 400–500 band simply means your child's movement skills — things like balance, coordination, posture and the strength behind sitting, walking, running or fine hand movements — are at an early-to-emerging stage that benefits from focused support. It is not a diagnosis and not a ceiling; it is a precise map of where to begin. The clear next step is a short conversation with a Pinnacle clinician to turn that number into a practical, child-led plan.

What this band means and what comes next

The AbilityScore® is a structured, clinician-administered measure — the band tells your therapy team where your child's motor skills are today so support can be pitched at exactly the right level: not too easy, not overwhelming.

Typical next steps your clinician may discuss:

• A movement-focused review — looking at gross motor (large movements like sitting, crawling, walking, climbing) and fine motor (small precise movements like grasping, stacking, drawing) to see which skills are emerging and which need building first.
• Physiotherapy or occupational therapy — gentle, play-based sessions that build core strength, balance, coordination and the everyday skills your child uses, step by step.
• A home-practice plan — small, repeatable activities woven into daily play so progress continues between sessions.
• A re-measure over time — the band is a baseline; re-scoring later shows progress clearly and keeps the plan tuned to your child.

With consistent, playful support, children in this band typically build steadily — the goal is confident, capable movement, not a number.

When to seek a check sooner

Speak to your paediatrician promptly if your child has lost a movement skill they once had, has marked stiffness or floppiness, struggles to bear weight, or if one side of the body moves very differently from the other — these warrant a medical review alongside any therapy.

The Pinnacle way

AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an app or a number alone. Across 70+ centres and 700+ therapists, your child can receive a precise motor profile through our physiotherapy and occupational therapy support, with the plan shaped by how the AbilityScore® is measured and used.
