Automated Fine Motor Evaluation for Developmental Coordination Disorder.

Area of Science:

• Pediatric Neurology
• Biomedical Engineering
• Developmental Psychology

Background:

• Developmental Coordination Disorder (DCD) affects 5-6% of school-aged children, impacting their quality of life.
• Current DCD assessment methods are subjective, costly, and difficult to scale.
• Objective and timely diagnosis is crucial for effective DCD intervention.

Purpose of the Study:

• To develop and validate an automated Fine Motor Evaluation System (FMES) for objective DCD assessment.
• To create automated algorithms for scoring fine motor skills in children.
• To provide a scalable, low-cost solution for DCD diagnosis.

Main Methods:

• A two-camera system records children performing fine motor tasks.
• Automated algorithms, including a CNN with temporal filtering, perform task localization and frame-wise classification.
• Feature extraction, time positioning algorithms, and image processing are used for individual task evaluation.

Main Results:

• The proposed FMES achieved effective fine motor evaluation for DCD assessment.
• Automated scoring demonstrated strong correlation with professional manual scoring.
• The system proved to be a low-cost, objective, and scalable solution.

Conclusions:

• The automated FMES provides an objective and efficient method for DCD assessment.
• This system has the potential to significantly improve diagnostic accessibility for a larger population.
• The developed automated evaluation methods support timely intervention for children with DCD.
