Exercise Monitoring and Assessment System for Home-Based Respiratory Rehabilitation

Exercise training is a key component of respiratory rehabilitation. Exercise monitoring and assessment have shown to be beneficial and have significant improvement in the outcome of exercise training. In this article, we propose a noninvasive exercise monitoring and assessment system (EMAS) for home-based respiratory rehabilitation exercises. EMAS exploits multiband microwave sensing techniques to monitor in real-time the patient's rehabilitation exercise training and synchronously provide online visual feedback for helping the patient better training. Then EMAS extracts exercise information (duration, intensity, and breathing changes) from all exercise data to assess the quality of rehabilitation exercise. We implement EMAS on the designed compact and portable prototypes and deploy it to monitor four subjects, resulting in one week of exercise data in total. System evaluations demonstrate that EMAS can accurately monitor rehabilitation exercises of each subject and obtain the exercise duration, exercise intensity, and breathing changes during rehabilitation exercises to achieve exercise assessment.
