Recent evidence has shown children at risk for DCD have associated auditory timing perception and auditory-motor synchronization deficits, but it remains unclear how these deficits would appear in full-body coordination tasks, particularly as DCD is often associated with gross motor impairments such as balance and gait. Current interventions for DCD focus on motor training alone, although preliminary findings suggest that motor interventions with rhythmic auditory cueing may confer additional benefit. To investigate auditory-motor synchronization during full-body coordination, we tested whether children aged 9–12 at risk for DCD could synchronize a step-clap dance step to various auditory stimuli using online data collection. Frequency analysis of the tracked head, hands, and feet showed that children at risk for DCD perform the dance step overall slower compared to typically developing children. Cross-correlations of the movements to an interpolated harmonic wave representing the auditory beats showed the group at risk for DCD were less coordinated to the auditory beat compared to typically developing children at the fast tempi, but that both groups performed similarly at slower tempi. Additionally, both groups were more coordinated and less variable at slower compared to faster tempi.

Our study aims to investigate whether training sessions involving movement synchronization to a variable fractally structured auditory cueing device can also enhance dexterity and reduce miss percentage in a Fitts' law task. Twenty-four participants were randomly assigned to three groups: two groups received training involving wrist oscillations synchronized to an auditory cue with a fractal structure or self-paced wrist oscillations without a cue, while the third group received no training. Following four training sessions, the training groups completed a post-Fitts' Law task to assess any improvements in dexterity, while the untrained group completed the post-Fitts' Law task two weeks after their initial assessment. The results indicated that all groups improved accuracy, although there was no enhancement in the speed of striking the targets. Contrary to our hypothesis, the fractally structured auditory cued training group did not demonstrate superior performance compared to the self-paced and no-training groups. However, subjects who showed improvement on the post-Fitts' Law task exhibited higher movement sample entropy during the training task, irrespective of the training group they were in.
