Virtual Reality Improves Predictive Internal Modeling and Object Control Skills in DCD Children

Area of Science:

• Motor Control and Learning
• Developmental Psychology
• Rehabilitation Technology

Background:

• Children with developmental coordination disorder (DCD) often face motor control and coordination challenges linked to internal modeling deficits.
• Virtual reality (VR) offers a promising avenue for improving motor skill acquisition and learning.

Purpose of the Study:

• To investigate the impact of VR-based interventions on internal modeling and object control skills in children with DCD.
• To assess the effectiveness of VR in enhancing predictive internal modeling and its transfer to object control tasks.

Main Methods:

• A quasi-experimental design with pretest, post-test, and follow-up was used.
• Forty female students (7-10 years) with DCD were randomly assigned to a VR training group or a control group.
• Predictive internal modeling was assessed via continuous relative phase (CRP) in a visuomotor task, and object control skills were measured using the TGMD-2.

Main Results:

• VR training significantly improved CRP acquisition (p=0.037).
• The VR group showed superior transfer of skills to object control tasks compared to controls (p<0.001).
• Improvements suggest VR facilitated internal model development and application, though compensatory strategies persisted.

Conclusions:

• VR-based interventions can effectively enhance internal modeling and object control skills in children with DCD.
• VR facilitates the development and generalization of predictive internal models for motor tasks.
• Persistent challenges in internal model updating highlight the need for continued therapeutic strategies.
