Gross Motor Delay
AbilityScore 400–500 for Gross Motor Delay: your next steps
An AbilityScore of 400–500 in Gross Motor Delay is a starting baseline, not a verdict. The next step is to convert it into a personalised physiotherapy plan with 2–3 clear goals, build daily floor play and practice into routine, and re-measure against your child's own baseline. Only a Pinnacle clinician can diagnose or confirm.
An AbilityScore in the 400–500 band is not a verdict — it's a starting line, and a clear one. Here's exactly what to do next.
In short
Your child's AbilityScore is a clinician-administered snapshot of where their [gross motor skills](/) sit today — the big movements like rolling, sitting, crawling, standing and walking. A 400–500 band tells your Pinnacle team where to begin and gives you a baseline to measure real progress against. The next step is simple: turn that number into a personalised plan with a physiotherapist, and start. Early, consistent support is where the biggest gains live.What this band means — and what to do
Think of the band as a map reference, not a label. It helps your clinician set the right starting point — not too easy, not overwhelming — and choose the activities that build the next milestone in the natural order: head control, sitting balance, crawling, pulling to stand, cruising, then independent steps.What to do next, practically:
- Convert the score into a plan. Sit with your physiotherapist to agree 2–3 specific goals (for example, sitting unsupported for a minute, or pulling to stand) and how often you'll practise.
- Build practice into daily life. Floor play, tummy time, reaching games and supported standing matter more than any single session.
- Re-measure on schedule. Progress in gross motor delay often comes in spurts and plateaus — a plateau is not failure. Repeat measurement against your child's own baseline makes quiet progress visible.
- Check the foundations. Your clinician will also look at muscle tone, vision and general health, since these shape motor development.
The Pinnacle way
No number from a form is a diagnosis. A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under the care of a qualified clinician who sees your child in person. Your AbilityScore band simply tells the team where to start and lets us prove progress over time — measured against your child, not against other children. With 25 million+ therapy sessions behind our approach, the focus is always the next achievable milestone, gently and steadily.Trusted sources

What to watch
Watch for whether new milestones emerge in order over weeks — better head control, sitting balance, then pulling to stand. Seek a prompt review if your child loses a skill they once had, stiffens or feels floppy, or shows strong one-sided preference, as these need a clinician's eye sooner.
Try this at home
Make the floor your child's favourite place. Place a loved toy just out of reach during tummy time or sitting, and cheer every reach, wobble or scoot — ten minutes, a few times a day, builds the strength and balance that milestones are made of.

Frequently asked
Is an AbilityScore of 400–500 a bad result?
No — it isn't a grade or a verdict. It's a clinician's snapshot of where your child's gross motor skills sit today, used to set the right starting point and to measure progress against your child's own baseline over time.
Will my child catch up?
Many children make strong gains with early, consistent support. Gross motor development moves in spurts and plateaus, so progress is best judged by re-measuring against your child's own baseline rather than comparing with other children. Your physiotherapist will set realistic, milestone-by-milestone goals.
How often should we re-check the AbilityScore?
Your clinician will recommend a re-measurement schedule based on your child's plan. Repeat measurement is what separates a normal plateau from a pattern that needs the plan adjusted — and it makes quiet progress visible.
Can I get a diagnosis from this score online?
No. No diagnosis is ever made from an online form or a number. A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under a qualified clinician who assesses your child in person.
