Why Some Children Can’t Sit Still — And How Movement Can Help
A child who can’t sit still. A child who blurts out answers before the question is finished. A child whose emotions seem to hijack them without warning. For decades, the response to these behaviours has been largely the same: medication. But a growing body of research suggests there’s a deeper explanation — and a different way to help. Rhythmic Movement Training International (RMTi) addresses that explanation directly.
The Reflex Behind the Restlessness
One of the most striking findings in this field involves the Spinal Galant Reflex, which triggers when the skin along one side of the spine is stroked — the back of a chair, a waistband, even a shirt tag can set it off. When retained, it causes involuntary hip movement and a near-constant need to squirm. Many children diagnosed with ADHD show a retained Spinal Galant — not because they’re badly behaved, but because their nervous system is being triggered by perfectly ordinary contact, over and over, all day.
The Asymmetrical Tonic Neck Reflex (ATNR) and Symmetrical Tonic Neck Reflex (STNR) are also strongly associated with ADHD. A retained STNR makes sitting at a desk uncomfortable — looking down at work pulls the arms to bend and legs to extend, which is awkward under a desk — contributing to the constant shifting and fidgeting so often read as inattention.
The Alarm That Won’t Switch Off
A retained Moro Reflex keeps the nervous system scanning for threat. This isn’t a child choosing to be distractible — it’s a stress response system stuck in the “on” position, making hypervigilance and emotional volatility the baseline rather than the exception. Add a retained Fear Paralysis Reflex, and impulsivity makes more sense too: when you’re in fight-or-flight, you react before you think.
Building From the Bottom Up
The basal ganglia and cerebellum — both involved in inhibiting unwanted movement and making behaviour automatic — depend on movement stimulation to develop. When this stimulation was missed in infancy, RMTi offers a second chance: gentle, rhythmic movement that mirrors what should have happened naturally, helping these structures mature and the associated reflexes integrate.
What the Research Shows
One twelve-week training programme for children with ADHD found significant reductions in retained primitive reflexes alongside improvements in motor and cognitive function. Other studies describe parents using RMTi reporting real gains in attention, coordination, and behaviour.
A Different Question to Ask
Instead of “how do we manage this behaviour,” RMTi asks “what is this behaviour telling us about the nervous system underneath it.” For many children, that question — and the gentle movement work that follows it — opens a path beyond simply managing symptoms toward genuine, lasting change.
