Background:We compared children with, at-risk for, or without developmental coordination disorder (DCD) on the Test of Gross Motor Development (TGMD-2) and the Movement Assessment Battery for Children (MABC) through (a) correlations, (b) gender and age comparisons, (c) cross tab analyses, and (d) factor analyses.Method:Children (N = 424; age range: 4–10 years) from southern Brazil completed the TGMD-2 and MABC and placed into groups (DCD: ≤ 5th%, n = 58; at-risk: > 5th to ≤ 15th%, n = 133; typically developing (TD) >16th%, n = 233).Results:The strongest correlation was between total performance on the TGMD-2 and MABC (r = .37). No gender differences were found for performance on the MABC while boys performed better than girls on the TGMD-2. Cross tab analyses indicated a high level of agreement for children who performed in the lowest percentiles on each assessment. Factor analyses suggested that, for both the TD and at-risk groups, three factors loaded on the motor assessments. In contrast, the DCD group loaded on a sport skill, general skill, and a manipulative skill factor, accounting for 42.3% of the variance.Conclusions::Evidence suggests that children who perform very poorly on one assessment are likely to perform poorly on the other. Children with DCD may have sports-related skill deficiencies.

AVG may provide an appealing means by which all individuals can increase their overall physical activity levels, although AVG should not be seen as a replacement for walking or other forms of PA. Although further research is necessary, the finding that both groups performed similarly in AVG suggests that games can potentially be played without modifications or adaptations to gaming units, which may provide several advantages in terms of social/cost/ease of accessing unit.

The primary purpose of this study was to examine the effect of auditory pacing on period stahility and temporal consistency of a dual motor task in children with and without dyslexia and with varying amounts of motor deficiency. Fifty-four children were divided into groups based on dyslexia diagnosis and score on the Movement Assessment Battery for Children-Second Edition (Movement ABC-2). Participants performed a dual motor task (clapping while walking) at a self-determined pace in a pretest block, practiced 4 blocks of 4 trials with a metronome pacing signal, and finished with a posttest hlock without auditory pacing. Measures of period stability (interclap/interheel strike intervals across trial blocks) and temporal consistency (coefficient of variation of period with trials) were taken. The results suggest that auditory pacing may improve period stability across groups, but does not appear to impact temporal consistency. Weak support existed for a general impairment of motor function in children diagnosed with dyslexia.
