Motor Coordination in Autism Spectrum Disorders: A Synthesis and Meta-Analysis
๐ Original study โPlain English Summary
This big-picture analysis pooled 41 studies spanning three decades to ask: do people with autism spectrum disorders (ASD) have unusual motor coordination โ balance, arm movements, walking? The answer was a resounding yes. The gap between autistic and non-autistic individuals was large and consistent across every age group, limb, and ASD subtype. Statistical checks confirmed the finding was rock-solid, not a fluke of selective publishing. Why does this matter? If clumsy movement is a core feature of autism, it flips a major debate. Communication difficulties might stem partly from motor problems rather than lacking social motivation, making movement-based support just as important as social skills training.
Abstract
Are motor coordination de๏ฌcits an underlying cardinal feature of Autism Spectrum Disorders (ASD)? Database searches identi๏ฌed 83 ASD studies focused on motor coordination, arm movements, gait, or postural stability de๏ฌcits. Data extraction involved between-group comparisons for ASD and typically developing controls (N = 51). Rigorous meta-analysis techniques including random effects models, forest and funnel plots, I2, publication bias, fail-safe analysis, and moderator variable analyses determined a signi๏ฌcant standardized mean difference effect equal to 1.20 (SE = 0.144; p < 0.0001; Z = 10.49). This large effect indicated substantial motor coordination de๏ฌcits in the ASD groups across a wide range of behaviors. The current overall ๏ฌndings portray motor coordination de๏ฌcits as pervasive across diagnoses, thus, a cardinal feature of ASD.
