What an AbilityScore® of 100–200 means in Gross Motor Delay
An AbilityScore® band of 100–200 in Gross Motor Delay is a clinician-administered starting baseline — a snapshot of your child's big-movement skills that guides therapy and is re-measured to show progress. It is a map reference, not a verdict, and only a Pinnacle clinician can interpret it for your child.

When you see a number on a developmental measure, it's natural to want to know what it really means for your child — so let's make it clear and calm.
In short
An AbilityScore® band of 100–200 for a child with Gross Motor Delay is a starting picture — a clinician-administered snapshot of where your child's big-movement skills (sitting, crawling, standing, walking, balance, coordination) are right now, compared with their own developmental stage. A band like this signals that focused support is worthwhile and, importantly, that there is real room to grow. It is a baseline to build from, not a verdict — and it tells your therapist exactly where to begin.
What this band actually tells you
Think of the AbilityScore® band as a map reference, not a final destination:
- It is your child's own baseline — measured against their stage of development, not ranked against other children.
- It guides the plan — it shows the clinician which gross-motor building blocks (core strength, postural control, balance, gait) to prioritise first.
- It is designed to be re-measured — the real value comes when the same structured assessment is repeated, so progress becomes visible rather than guessed.
Gross motor skills tend to develop in spurts and plateaus rather than a straight line, so one number on one day is a chapter, not the whole story. The band helps your therapist set realistic, motivating next goals.
When to seek assessment
If your child is noticeably late to hold their head steady, sit, crawl, pull to stand or walk, or seems unusually stiff or floppy, a developmental check is a kind and sensible step. Persistent asymmetry (always favouring one side) or losing a motor skill once gained deserves prompt review with a clinician.
The Pinnacle way
Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional., under the care of a qualified clinician — never from an online form or a single number. Our therapists use this structured, clinician-administered assessment to design a personalised plan and to re-measure progress against your child's own baseline. With 25 million+ therapy sessions and 4.95 lakh+ families served across 70+ centres, the aim is always the same: your child moving, playing and thriving with confidence.

Next step — A number is most useful when a clinician explains it for your child. Book a gross-motor assessment with a Pinnacle physiotherapist and turn this baseline into a plan.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Seek a developmental check sooner if your child loses a motor skill once gained, always favours one side of the body, or seems persistently very stiff or very floppy when moving or being handled.
In everyday life
Build in daily floor play and supervised tummy time or movement breaks: reaching for a favourite toy just out of range, cruising along furniture, or stepping over soft cushions. Short, playful, repeated practice gently strengthens the core and balance that gross motor skills are built on.

Bring your questions to a first visitQuestions families ask
Is an AbilityScore® of 100–200 a diagnosis of Gross Motor Delay?
No. The AbilityScore® band is a clinician-administered baseline that describes where your child's gross-motor skills are now. A diagnosis is formed only at a Pinnacle Blooms Network centre by a qualified clinician, who considers many factors together.
Can my child's AbilityScore® band improve?
Yes — the assessment is designed to be re-measured against your child's own earlier baseline, so progress from therapy and home practice becomes visible. Gross motor development often moves in spurts and plateaus, so steady, repeated measurement is the fairest way to see real change.
What kind of therapy helps gross motor delay?
Physiotherapy is usually central, focusing on core strength, postural control, balance and coordination through play-based, age-appropriate activities. Your Pinnacle clinician designs the plan around your child's specific baseline and goals.
