Tool choice follows age, referral question and whether discriminative or evaluative data are needed.","answer_md":"*A gross motor delay is rarely a single observation — it is a pattern across postural control, locomotion and coordination, captured the same way every time.*\n\n## In short\nGross motor delay in early childhood is best characterised with norm-referenced and criterion-referenced motor instruments rather than informal observation alone. The most widely used standardised tools are the **Alberta Infant Motor Scale (AIMS)** for infants up to independent walking, the **Peabody Developmental Motor Scales — 2nd edition (PDMS-2)** for birth to 5 years, the **Bayley Scales of Infant and Toddler Development (Bayley-4)** motor composite, and the **Gross Motor Function Measure (GMFM-66/88)** where cerebral palsy is suspected. Tool choice follows the child's age, the referral question and whether you need discriminative, evaluative or predictive data.\n\n## The science, briefly\nThese instruments map onto the WHO ICF framework — AIMS observes spontaneous antigravity movement and weight-bearing in prone, supine, sitting and standing; PDMS-2 separates reflexes, stationary control, locomotion and object manipulation; Bayley-4 yields fine and gross motor scaled scores for population-referenced standing; and the GMFM is the evaluative gold standard for tracking change over time. Pairing a discriminative tool (does a delay exist?) with an evaluative one (is the child progressing?) gives the most defensible clinical picture. Always confirm hearing, vision and a paediatric medical review before attributing delay to motor immaturity alone.\n\n## The Pinnacle way\nA clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a form or an app. Our therapists integrate these standardised motor instruments within a structured, clinician-administered assessment to set a clear baseline for [gross motor delay](/gross-motor-delay) and a measurable [paediatric physiotherapy plan](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate).\n\n## Trusted sources\nWHO ICF and ICD-11 functioning frameworks; AAP developmental surveillance guidance; CDC developmental milestone resources.\n\n**Next step —** Refer a child or partner with us — [arrange a clinician-led motor assessment](https://www.pinnacleblooms.org/enroll-autism-speech-aba-therapies-india).\n\nThis is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.","canonical":"https://pinnacleblooms.org/ask/which-standardised-tools-are-used-to-assess-gross-motor-delay-in-early-childhood","editorial":{"reviewed_at":"2026-06-11T20:12:18.613642+00:00","reviewed_by":null,"developed_by":"SETU
