In-Motion-App for remote General Movement Assessment: a multi-site observational study.

Area of Science:

• Pediatric neurology
• Developmental pediatrics
• Medical technology

Background:

• General Movement Assessment (GMA) is crucial for evaluating infant neurological development.
• Remote assessment methods are needed to improve accessibility and efficiency.
• The In-Motion-App aims to facilitate home-based video recording for GMA.

Purpose of the Study:

• To evaluate the compliance of parent-recorded infant videos with In-Motion-App standards for GMA.
• To assess the feasibility of remote scoring by trained GMA observers.
• To explore the utility of home videos for automated movement tracking and gauge parental experience.

Main Methods:

• A multi-center prospective observational study involving high-risk infants and their parents.
• Parents recorded infant spontaneous movements following In-Motion-App standards.
• Videos were assessed for GMA scorable quality, and automated body tracking software accuracy was evaluated.
• Parental feedback on the app and instructions was collected via surveys.

Main Results:

• 96% of 130 videos met the requirements for GMA assessment.
• Automated body tracker software achieved over 80% accuracy in detecting body key points.
• Most parents found instructions easy to follow and reported no increased anxiety about their child's development.

Conclusions:

• Parents can effectively record infant movements compliant with GMA standards using the In-Motion-App.
• Automated body point tracking software shows promise for clinical and research applications.
• Home-based video recording is a viable, non-anxiety-provoking method for infant assessment.
