Screening & diagnostic pathway for Gross Motor Delay under 7
Gross motor delay in under-7s follows a surveillance-plus-screening pathway: milestone tracking at every visit, validated screens at routine checkpoints, and prompt referral for neuromotor assessment to differentiate central, peripheral and orthopaedic causes before therapy planning. Diagnosis is formed only at a Pinnacle centre under clinician care.

A child who is slow to roll, sit, stand or walk rarely needs alarm — they need a structured pathway that catches the treatable causes early.
In short
For gross motor delay in children under 7, use a surveillance-plus-screening model: developmental surveillance at every well-child visit, a validated standardised screen at the 9, 18 and 30-month checkpoints (or whenever concern arises), and prompt referral for formal motor assessment when milestones fall outside expected windows or are lost. Diagnostic evaluation differentiates central from peripheral causes and identifies treatable contributors before therapy planning.
The pathway
1. Surveillance & screening — Track gross motor milestones at each visit. Apply a standardised tool (e.g. ASQ-3 or PEDS) at routine checkpoints. A single missed milestone warrants closer monitoring; multiple delays, asymmetry, hypertonia, hypotonia or regression warrant referral.
2. Targeted history & examination — Perinatal history, family history, and a neuromotor exam assessing tone, posture, reflexes, symmetry and gait. Screen vision and hearing.
3. Differentiate the cause — Distinguish central (e.g. cerebral palsy, global delay), peripheral/neuromuscular, and orthopaedic origins. Raised CK, persistent toe-walking with tightness, or fasciculations point neuromuscular; consider genetic/metabolic workup where indicated.
4. Red flags for urgent referral — Loss of acquired skills, persistent asymmetry, marked hypotonia with poor feeding, or suspected progressive disorder need prompt paediatric neurology input — not a therapy-first route.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a screen alone. Once the cause is clarified, our physiotherapy and motor pathway builds a structured plan around the child's gross motor profile.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Loss of acquired motor skills, persistent asymmetry, marked hypotonia with poor feeding, or progressive weakness — these warrant prompt paediatric neurology referral rather than a therapy-first route.
In everyday life
Document milestone timing against a standardised tool at each visit; serial measurements detect plateau or regression far earlier than a single snapshot.

Bring your questions to a first visitQuestions families ask
At what ages should gross motor screening occur?
Apply developmental surveillance at every well-child visit and a validated standardised screen at the 9, 18 and 30-month checkpoints, or at any visit where a parent or clinician raises concern.
When should I refer beyond therapy to neurology?
Refer urgently for loss of acquired skills, persistent asymmetry, marked hypotonia with poor feeding, or any sign of a progressive disorder. These need paediatric neurology assessment rather than a therapy-first approach.
How is the cause of motor delay differentiated?
A neuromotor exam plus targeted history distinguishes central, peripheral/neuromuscular and orthopaedic origins. Raised CK, vision/hearing screens and selective genetic or metabolic workup guide the diagnostic direction.
