Signs of Cerebral Palsy a Nurse Should Watch For

A nurse is often the first set of trained eyes on a young child — and recognising the early motor signs of cerebral palsy can open the door to support that changes a child's trajectory.

In short

Cerebral palsy (CP) is a group of disorders of movement and posture caused by non-progressive injury to the developing brain. In a young child, the signs a nurse should watch for cluster around abnormal muscle tone, asymmetry, delayed or atypical motor milestones, and persistent primitive reflexes. These are red flags for onward developmental and paediatric review — not a diagnosis. Early identification supports timely referral, which is the single most useful contribution a nurse can make.

Signs to watch for

Observe across tone, posture, movement and milestones, adjusting expectations to corrected age in preterm infants:

Tone and posture

• Hypertonia — stiffness, scissoring of the legs, fisted hands beyond 3–4 months, or a child who feels rigid when handled.
• Hypotonia — a floppy infant with poor head control beyond the expected age, who slips through your hands on vertical suspension.
• Persistent asymmetry — early hand preference before 12 months, or consistently favouring one side.

Movement and reflexes

• Abnormal, jerky, writhing or restless movements; or notably reduced spontaneous movement.
• Persistence of primitive reflexes (e.g. Moro, ATNR) beyond the age they should integrate.
• Difficulty with feeding — poor suck, excessive drooling, frequent gagging or tongue thrust.

Milestones (key delays)

• Not holding head steady by ~4 months.
• Not rolling, or not sitting with support by the expected window.
• Not bearing weight on legs, or W-sitting and bottom-shuffling with stiffness.
• Toe-walking or asymmetric crawling.

The General Movements Assessment and standardised milestone surveillance are useful structured aids alongside clinical observation.

When to refer

Refer for prompt paediatric and developmental review when tone is clearly abnormal, asymmetry persists, milestones lag significantly, or a high-risk history is present (prematurity, low birth weight, neonatal encephalopathy, kernicterus, neonatal seizures). Earlier referral enables earlier intervention during the period of greatest neuroplasticity. CP itself is non-progressive, but secondary complications (contractures, hip displacement) benefit from early management.

The Pinnacle way

AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — your structured observations as a nurse are invaluable in triggering that referral. Pinnacle provides a clinician-administered structured assessment that builds a functioning profile across motor, communication and daily-living domains. Explore the Pinnacle network, our physiotherapy and motor support, and how the AbilityScore® is determined.
