Autism & Developmental

Characterising the Early Presentation of Motor Difficulties in Autistic Children.

Reynolds et al. (2022) · Journal of autism and developmental disorders 2022
★ The Verdict

Roughly half of autistic 2-7-year-olds show motor delays that hang around, so test early and track often.

✓ Read this if BCBAs running early-intervention or preschool programs.
✗ Skip if Clinicians who only serve fully verbal teens with no motor goals.

01Research in Context

01

What this study did

Farley et al. (2022) watched a group of autistic kids aged 2-7. They gave each child a standard motor test and asked parents about daily motor skills.

The team wanted to know how many kids scored low and whether early test scores matched later parent reports.

02

What they found

About one-quarter to one-half of the children showed clear motor delays on the test. Parents of these early-delayed kids later reported more trouble with riding bikes, writing, or dressing.

In short, low scores at age three often meant real-life problems at age six.

03

How this fits with other research

Provost et al. (2007) saw almost every toddler with autism fail motor items, while E et al. found only 25-60%. The gap is age: Beth looked at 2-year-olds, E followed kids up to seven. Delays may lessen or hide as children grow.

Little et al. (2015) linked weak grip to brain-stem wiring in older boys. E’s finding that early delays linger fits this biology: the same circuits stay weak.

Izadi-Najafabadi et al. (2015) showed autistic kids can learn a new motor game if you let them pick up the pattern without heavy verbal rules. E’s call to monitor milestones pairs well: check progress, then teach through implicit practice rather than long explanations.

04

Why it matters

Screen every young client with a quick motor test, even if speech or social goals feel urgent. Flag low scores and re-check each six months. When delays stick, add fine- and gross-motor targets to the treatment plan and choose implicit learning drills—short demos, lots of reps, few verbal steps.

03Original abstract

This study aimed to explore the rates of motor difficulties in children from the Australian Autism Biobank, and how early motor concerns impacted on children functionally. Children with autism aged 2-7 years, including 441 with a Vineland Adaptive Behavior Scale (VABS-II) motor subscale and 385 with a Mullen Scales of Early Learning (MSEL) fine motor subscale were included (n total = 514; 80% male). Approximately 60% of children on the MSEL and ~ 25% on the VABS-II had clinically significant motor impairments. More children with delayed sitting and walking motor milestones had early childhood parent reported motor difficulties (p < 0.001). Early motor delays or concerns may assist identifying individuals who will likely benefit from early ongoing developmental monitoring and early support.
