Communication Deficits and the Motor System: Exploring Patterns of Associations in Autism Spectrum Disorder (ASD).
Fine motor skills march with both expressive and receptive language in autism, while gross motor gaps mainly drag down understanding—so pair motor goals with language targets.
01Research in Context
What this study did
The team looked at kids with autism who had different motor skill levels.
They split the children into two groups: those with weak fine motor skills and those with typical fine motor skills.
Then they checked how each group scored on expressive and receptive language tests.
What they found
Kids with weak fine motor skills also had lower expressive and receptive language scores.
Surprisingly, big body (gross motor) problems only pulled down receptive language.
Fine and gross motor skills seem to take separate roads to language.
How this fits with other research
Sosnowski et al. (2022) watched babies from infancy and saw the same pattern: shaky motor paths early on predicted later language delays.
Redquest et al. (2021) also found that fine motor hiccups at 9-14 months flagged later autism risk, backing the fine motor-language link.
Garrido et al. (2017) looks like a clash: they report medium language gaps in autism siblings yet only tiny motor gaps. The difference is they studied at-risk babies, not kids already diagnosed. Once autism is present, motor and language drop together.
Why it matters
When a client’s language program stalls, run a quick fine motor probe. Adding tasks like pinching beads or stacking blocks may give language a lift. If receptive language is the weak spot, also screen gross motor games such as balance and jumping. Target the motor lane that matches the language gap and you may see words start to move.

03Original abstract
Many children with autism spectrum disorder (ASD) have notable difficulties in motor, speech and language domains. The connection between motor skills (oral-motor, manual-motor) and speech and language deficits reported in other developmental disorders raises important questions about a potential relationship between motor skills and speech-language deficits in ASD. To this end, we examined data from children with ASD (n = 1781), 2-17 years of age, enrolled in the Autism Speaks-Autism Treatment Network (AS-ATN) registry who completed a multidisciplinary evaluation that included diagnostic, physical, cognitive and behavioral assessments as part of a routine standard of care protocol. After adjusting for age, non-verbal IQ, Attention Deficit Hyperactivity Disorder (ADHD) medication use, and muscle tone, separate multiple linear regression analyses revealed significant positive associations of fine motor skills (FM) with both expressive language (EL) and receptive language (RL) skills in an impaired FM subgroup; in contrast, the impaired gross motor (GM) subgroup showed no association with EL but a significant negative association with RL. Similar analyses between motor skills and interpersonal relationships across the sample found both GM skills and FM skills to be associated with social interactions. These results suggest potential differences in the contributions of fine versus gross motor skills to autistic profiles and may provide another lens with which to view communication differences across the autism spectrum for use in treatment interventions.
