Evaluating the influence of feedback on motor skill learning and motor performance for children with developmental coordination disorder: a systematic review

Introduction

Children with developmental coordination disorder (DCD) have difficulties with learning and performing physical tasks. It is well known that task-specific practice is effective in improving motor skills. Additional feedback during practice may function as a quality improvement mechanism and therefore enhance motor skill outcomes.

Aims

To investigate the effect of different forms of feedback on motor learning and motor performance in children with DCD.

Methods

A systematic review was conducted (registration CRD42020175118) to investigate the effectiveness of different types of feedback, compared to other forms of feedback, or no additional feedback, on motor learning and motor performance outcomes in children with DCD. The search was run across six electronic databases (last search January 2024). Two reviewers independently screened studies for inclusion, assessed the quality of included studies, and extracted relevant data. A narrative synthesis was performed and included studies that assessed motor learning and/or performance outcomes following an intervention that delivered a specific form of feedback in comparison to another form of feedback or no specific feedback.

Results

14 articles from 13 trials were included in this review. Feedback was delivered by providing various forms of feedback, including: knowledge of results, focus of attention and augmented feedback delivered via technology. No significant differences were found between different forms of feedback for motor learning or performance outcomes for children with DCD. Interventions that used technology (with augmented feedback) to deliver the intervention were found to be as effective as traditional therapy. All groups who participated in therapy, regardless of the presence or type of feedback received, improved in overall scores on a motor performance outcome assessment.

Conclusion

Despite the clear rationale for using feedback-oriented interventions for children with DCD, there is surprisingly limited and low-quality research. There is no clear evidence that one form of feedback is more effective than another, although it appears that feedback delivered via technology may be as effective as feedback delivered in traditional therapy interventions for children with DCD. Further exploration is required from appropriately powered and well-designed trials.

Visuomotor adaptation and its relationship with motor ability in children with and without autism spectrum disorder

The high prevalence rates of motor impairments among individuals with autism spectrum disorder (ASD) lead to increased attention to motor learning. The current study examined the visuomotor adaptability in children with and without ASD using a computerized visuomotor adaptation task in which the real-time visual feedback of hand movement was rotated. The relationships between visuomotor adaptability and clinical symptomology were also investigated. Results revealed that the children with ASD showed a slower rate of improvement and smaller after-effects than their peers on the measures of motor planning. Additionally, autistic characteristics significantly moderated the association between individuals' adaptability and fine motor skills. The findings contribute to the growing evidence of compromised visuomotor adaptability, which suggested the importance of addressing these clinical features of ASD.

Inter-limb transfer of kinematic adaptation in individuals with motor difficulties

A previous study suggested that adults with greater motor difficulties demonstrated less adaptation under a regular error feedback schedule (gain=1:1) but reached a similar level of adaptation compared to controls when feedback was enhanced (gain=1:2). In light of these findings, the present study examined inter-limb transfer after adults adapted to visuomotor distortions with their dominant hand on either regular or enhanced feedback schedules. Results revealed that successful transfer related to the magnitude of adaptation with their dominant hand regardless of the individuals' motor abilities on the regular feedback schedule. When the feedback was enhanced, the transfer was not related to either the adaptation of the dominant hand or individuals' motor abilities. We argue that a stable internal model is essential for inter-limb transfer in kinematic adaptation.
