• The assessment and training of respiratory muscles are two essential tasks for indirect screening of status and improvement of lung function, respectively, especially in times of COVID-19. To perform both tasks, we have designed an innovative handheld mouth pressure biofeedback system for assessment and personalized game-based training of respiratory muscle strength. Thirty recovered COVID-19 patients were involved in an across-ages pilot study to evaluate their respiratory muscle strength and the system's usability, and eight of the thirty patients were involved in a home inspiratory training program of 3 weeks to assess its effectiveness. Results revealed that participants rated the system's overall usability as excellent (91.3 ± 6.4) and consistently performed respiratory cycles along with the game-based training program in terms of mouth pressure. Furthermore, patients involved in the home training program showed a 40% increase in their Maximal Inspiratory Pressure (Pimax). These results indicate that the proposed system stands for a proper healthcare solution for the initial diagnosis of respiratory muscle dysfunction or disease and for guiding the correct performance of tailored and consecutive threshold load breathing cycles playfully and engagingly. Furthermore, it stands for an attractive and personalized biofeedback solution to promote adherence to at-home therapy. Finally, it can be used to investigate new and effective training protocols that improve respiratory muscle performance.
