Purpose: There is a relationship between motor and language skills in children with Autism Spectrum Disorder (ASD), but little work addresses the ramifications of this relationship for professionals who teach motor skills to this population. Within a motor skills intervention, this study probed the importance of language skills for motor intervention. We examined the relationship between motor and language skills at baseline, and then the relationship between baseline language skills and motor improvements resulting from the intervention. Method: Twenty children aged 4-6 years with ASD participated. Eleven children received 20 hr per week of motor intervention for 8 weeks. Nine children did not receive motor intervention. Language skills (Mullen Scales of Early Learning) and motor skills (Test of Gross Motor Development -- 2) were assessed at baseline and post-intervention. Spearman correlations tested the associations between baseline language and baseline motor skills. This analysis was repeated in the intervention sample to test the association between baseline language level and response to intervention (motor skill changes from baseline to post-intervention). Results: Prior to intervention, locomotor skills are positively correlated (p < 0.001) with both receptive (rs = 0.827) and expressive (rs = 0.722) language skills. Similarly, object-control skills are positively correlated (rs < 0.001) with receptive (rs = 0.779) and expressive (rs = 0.729) language skills. However, those baseline language skills do not relate to motor change in the experimental group. Conclusion: These results suggest that motor programs may improve motor skills in children with ASD when language is supported, regardless of pre-program language ability.
