Stereotyped Movement Disorder: AbilityScore 400-500 — what next?
An AbilityScore band of 400-500 is a starting point, not a verdict. The next step is to review it with your Pinnacle clinician, agree a focused therapy plan, keep your child safe and comfortable, and re-measure progress against their own baseline over time.

You have a number, a name, and a child you love — now let's turn that into a calm, clear plan for what comes next.
In short
An AbilityScore® band of 400–500 is a starting point, not a verdict — it describes where your child is today so your clinician can build the right support and measure real progress against it. With Stereotyped Movement Disorder, the next step is straightforward: review this baseline with your Pinnacle clinician, agree a focused therapy plan, and put gentle, consistent strategies in place at home. The movements themselves are usually manageable; the priority is keeping your child safe, comfortable and free to learn and play.
What this means and what to do next
Stereotyped Movement Disorder (ICD-11 6A06) describes repetitive, self-directed movements — such as hand-flapping, rocking or body-rocking — that begin in early childhood. Many of these movements are harmless and self-soothing. The plan focuses on three things:
- Safety first — if any movement risks injury (head-banging, skin or hand harm), this is reviewed promptly with your clinician and protective strategies are put in place.
- Function over suppression — the goal is rarely to erase a self-soothing movement, but to widen your child's skills, communication and coping so the movements interfere less with learning and play.
- Re-measurement — your child's AbilityScore® is compared to their own baseline over time, so even quiet gains become visible and the plan adapts.
When to check in sooner
Speak to your clinician promptly if movements suddenly increase, cause injury, appear alongside loss of skills, or are accompanied by staring spells or unusual changes in awareness — these need timely medical review rather than therapy alone.
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 number alone. Your therapist will translate this 400–500 band into a personalised plan drawing on therapy services and review it against your child's own AbilityScore baseline. With 70+ centres, 700+ therapists and 25 million+ therapy sessions behind us, you are not navigating this alone.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Check in with your clinician sooner if movements suddenly increase, cause injury (such as head-banging or skin harm), appear with loss of previously learned skills, or come with staring spells or unusual changes in awareness.
In everyday life
When a self-soothing movement appears, notice what came just before it — tiredness, noise, excitement or a hard moment. Gently offer an alternative comfort (a squeeze toy, a cuddle, a calm corner) rather than stopping the movement abruptly, and tell your therapist what you notice.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Does an AbilityScore of 400-500 mean my child's condition is severe?
No. The AbilityScore band describes where your child is today across developmental areas — it is a baseline for planning and measuring progress, not a severity label or a diagnosis. Your clinician interprets it in the full context of your child.
Should we try to stop the repetitive movements completely?
Usually not. Many stereotyped movements are self-soothing and harmless. The aim is to keep your child safe, widen their skills and coping, and reduce how much the movements interfere with learning and play — not to erase a comfort behaviour.
When should the movements prompt a medical review rather than therapy?
Speak to your clinician promptly if movements cause injury, suddenly increase, come with loss of skills, or are accompanied by staring spells or unusual changes in awareness. These need timely medical assessment.
How will we know if the therapy plan is working?
Progress shows up in everyday wins — calmer transitions, new skills, less interference from the movements — and in objective re-measurement against your child's own earlier AbilityScore baseline, reviewed with your clinician.
