Validation of a Portable Game Controller to Assess Peak Expiratory Flow Against Conventional Spirometry in Children

A novel 3D-printed, tablet-based game controller serves as a viable, engaging alternative for monitoring peak expiratory flow in pediatric asthma patients. By integrating pulmonary function testing into a gaming interface, this technology aims to improve patient adherence to self-monitoring protocols. The primary thesis posits that gamification can bridge the gap between clinical necessity and patient engagement, transforming routine respiratory assessments into a more accessible and interactive experience for children.

Clinical validation involving 158 pediatric participants demonstrates that the device achieves a 96.2% reproducibility rate and maintains a strong correlation of r=0.83 with conventional spirometry. These findings indicate that the portable controller provides data quality comparable to standard medical equipment while significantly enhancing user satisfaction. The cross-sectional study confirms that the device is both intuitive and effective, suggesting that serious games represent a promising frontier in chronic disease management.

While the current findings support the technical accuracy and usability of the controller, the scope remains focused on controlled validation within a clinical context. Future research must transition toward assessing the device’s long-term clinical impact and reliability in out-of-hospital, real-world settings. By successfully aligning standardized pulmonary function testing with the principles of pediatric engagement, this innovation offers a scalable solution for improving self-management outcomes in asthma care.
