An AbilityScore band of 400-500 in Gross-Motor is a structured snapshot of how your child is moving against their own baseline across big-muscle skills like sitting, walking and balancing. It is not a diagnosis but a starting point that guides support. Only a Pinnacle clinician can interpret what the band truly means for your child.

*When you see a number on a band, what you really want to know is simple — is my child okay, and what comes next?*

## In short
An AbilityScore® band of **400–500 in Gross-Motor** is a structured snapshot of how your child is moving right now — how they use the big muscles for sitting, crawling, standing, walking, running, balancing and climbing — measured against their own developmental baseline. A band is **not a diagnosis** and not a verdict; it is a starting point that tells our clinicians where to look more closely and how to shape support. The most useful thing it does is turn a worry into a clear, gentle plan.

## What the Gross-Motor band is actually telling you
Gross-Motor is all about the *big movements* — the strength, coordination and balance your child uses to roll, sit, pull to stand, walk, jump and navigate the world. A band gives a sense of where your child sits relative to expected milestones for their stage, but the band number alone is never the full story. What matters is the **pattern behind it**:

- **The shape of the movement** — is your child's posture steady, are both sides of the body working together, do they move smoothly or tire quickly?
- **The why, not just the what** — a lower score might reflect low muscle tone, less practice, caution, or simply a child finding their own timeline.
- **The trajectory** — one band at one moment matters far less than how your child grows from it with the right play, environment and, where helpful, therapy.

Think of the band as a *map reference*, not a label. It helps a clinician decide whether your child simply needs more opportunity to practise, or whether targeted physiotherapy would help them move with more ease and confidence.

## When to seek a closer look
It is worth a gentle professional review if, alongside this band, you notice your child consistently missing big movement milestones, strongly favouring one side, seeming unusually floppy or stiff, or showing frustration and avoidance around physical play. Early movement support is wonderfully effective — the younger the start, the more naturally new skills tend to take root.

## The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under the care of a qualified clinician — never from a number read in isolation. The AbilityScore® is a clinician-administered structured assessment that reads your child against *their own* baseline, then turns that into a warm, practical plan. Backed by 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres, our clinicians pair this with hands-on support.
