What an AbilityScore of 100–200 in Vestibular means

When you see a number beside your child's vestibular sense, what matters most is not the figure itself — but what it gently tells us about how your child feels safe and steady in the world.

In short

An AbilityScore® band of 100–200 in the Vestibular domain is one way our clinicians describe where your child currently sits in developing their sense of balance, movement and spatial steadiness — the inner-ear system that tells the brain where the body is in space. It is a starting picture, not a verdict, and it points towards areas where focused support can help your child feel more confident and grounded. The band only carries meaning when a Pinnacle clinician explains it against your child's own baseline and everyday life.

What the vestibular sense actually does

The vestibular system is your child's internal compass for movement and gravity. When it is developing well, a child can spin, climb, swing, sit still and shift position without feeling overwhelmed or unsteady. When this sense is still maturing, you might notice:

• Seeking lots of movement — constant spinning, rocking, jumping or rough-and-tumble, as if the body is searching for more input.
• Avoiding movement — wariness of swings, slides, stairs, escalators or having feet leave the ground.
• Balance and posture — frequent tripping, leaning on things, slumping, or tiring quickly when sitting upright.
• Coordination knock-on — difficulty with stairs, ball games, or knowing where the body is without looking.

A score band groups these patterns into a shared starting point, so therapy can be tailored rather than guessed. It tells the clinician where to begin — never what your child is limited to becoming.

How to read the band — and how to grow it

Think of the band as a baseline marker, like the first pencil line on a growth chart. The goal is movement forward from where your child is today. With the right sensory and movement-based play — gentle swinging, climbing, balance games and graded vestibular activities — children very often build steadiness and confidence over time. The band is revisited so progress is measured against your child, not against any other child.

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 figure or a single number read in isolation. The AbilityScore® is a clinician-administered structured assessment that reads your child against their own baseline and turns it 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 occupational therapy and sensory-integration support. Learn more on our home page and about what the AbilityScore is and how it's calculated.
