Persistent Toe-Walking: ICD-11 Features in Early Childhood
Persistent (idiopathic) toe-walking is a habitual ball-of-foot gait continuing beyond ~2 years that is unexplained by neuromuscular or orthopaedic cause — a diagnosis of exclusion. ICD-11 captures it under gait and mobility abnormalities; the clinician's task is to exclude spasticity, contracture and neurodevelopmental causes.

Most toddlers tiptoe occasionally — the clinical question is which ones keep doing it, and why.
In short
Persistent (idiopathic) toe-walking is a gait pattern in which a child habitually walks on the balls of the feet, with absent or reduced heel-strike, that continues beyond ~2 years of age once an independent gait is established and that is not explained by a neuromuscular, orthopaedic or other identifiable cause. It becomes idiopathic by exclusion — after cerebral palsy, spasticity, leg-length discrepancy, congenital tendo-Achilles shortening and neurodevelopmental conditions are ruled out. It is common, often bilateral, and frequently familial.
ICD-11 framing and the science
ICD-11 has no dedicated stem code for idiopathic toe-walking; clinically it is captured under abnormalities of gait and mobility, with the cause coded separately when one is found. Key early-childhood features for the clinician: intermittent or persistent equinus gait, capacity to stand and walk flat-footed on request (in early idiopathic cases), preserved passive ankle dorsiflexion initially, with progressive gastrocnemius–soleus tightening and reduced dorsiflexion range over time if untreated. Examine for asymmetry, hyperreflexia, clonus, regression or language/social concerns — any of these shifts the picture away from idiopathic toward a neurological or neurodevelopmental aetiology. A noted association exists with autism spectrum and sensory-processing differences, warranting a low threshold for broader developmental screening.
The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an online tool. Our teams differentiate idiopathic from secondary toe-walking and build a graded plan across persistent toe-walking support, targeted occupational therapy, and an AbilityScore baseline.

Next step — Refer a child with persistent equinus gait beyond age 2 for a structured clinical assessment.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Asymmetry, hyperreflexia or clonus, progressive loss of passive ankle dorsiflexion, inability to walk flat-footed on request, skill regression, or co-occurring language and social differences — each shifts the picture away from idiopathic toe-walking.
In everyday life
On examination, ask the child to stand and walk flat-footed deliberately: preserved capacity to do so, with normal passive dorsiflexion, supports an early idiopathic pattern rather than fixed contracture.
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
At what age does toe-walking become 'persistent'?
Occasional toe-walking is normal in early independent walking. It is considered persistent and warrants review when it continues habitually beyond roughly 2 years of age, once a mature gait would normally be establishing.
Is idiopathic toe-walking a diagnosis of exclusion?
Yes. The idiopathic label applies only after neuromuscular causes (e.g. cerebral palsy, spasticity), congenital tendo-Achilles shortening, leg-length discrepancy and relevant neurodevelopmental conditions have been excluded clinically.
Does ICD-11 have a specific code for toe-walking?
ICD-11 has no dedicated stem code for idiopathic toe-walking; it is captured under abnormalities of gait and mobility, with any identified underlying cause coded separately.
Is toe-walking linked to autism?
There is a recognised association between persistent toe-walking and autism spectrum and sensory-processing differences, so a low threshold for broader developmental screening is appropriate.
