Are motor coordination deficits an underlying cardinal feature of Autism Spectrum Disorders (ASD)... more Are motor coordination deficits an underlying cardinal feature of Autism Spectrum Disorders (ASD)? Database searches identified 83 ASD studies focused on motor coordination, arm movements, gait, or postural stability deficits. 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, I (2), publication bias, fail-safe analysis, and moderator variable analyses determined a significant standardized mean difference effect equal to 1.20 (SE = 0.144; p <0.0001; Z = 10.49). This large effect indicated substantial motor coordination deficits in the ASD groups across a wide range of behaviors. The current overall findings portray motor coordination deficits as pervasive across diagnoses, thus, a cardinal feature of ASD.

However, the diagnostic utility of the reported outcome measures has rarely been determined. Identifying outcome measures capable of predicting who is less likely to develop CAI could improve rehabilitation protocols and increase the efficiency of these measures. To determine the diagnostic utility and cutoff scores of perceptual, mechanical, and sensorimotor outcome measures between copers and people with CAI by using receiver operating characteristic curves. Case-control study. Sports medicine research laboratory. Twenty-four copers (12 men, 12 women; age = 20.8 ± 1.5 years, height = 173 ± 11 cm, mass = 78 ± 27 kg) and 24 people with CAI (12 men, 12 women; age = 21.7 ± 2.8 years, height = 175 ± 13 cm, mass = 71 ± 13 kg) participated.

Five methodological and experimental design concerns are identified in Vrtunski and Patterson'... more Five methodological and experimental design concerns are identified in Vrtunski and Patterson's (1985) article. The discussed concerns involved: (a) the use of misleading premotor segment terminology, (b) the uncertain status of the repeated measures sphericity assumptions, (c) mean calculations across unequal trials of the four levels of stimulus conditions, (d) improper selection of a main effect for post hoc analysis and discussion of these results when a significant interaction was present, and (e) conflicting text and table values. These concerns have prompted us to question their psychomotor decline conclusions. And unless Vrtunski and Patterson can convince us that these concerns are unjustified, we have no choice but to doubt seriously the validity of their conclusions.
