This study would be the first to evaluate implementing tele-exercise and remote monitoring program on pediatric CF patients. Our pediatric CF patients will be enrolled in a six-week exercise program that is streamed live from an instructor into their computers at home via a HIPAA compliant telemedicine platform. Remote monitoring devices, such as accelerometers and wireless heart rate monitors, will evaluate baseline habitual activity and intensity of exercise, respectively. The goal of this study is to show that tele-exercise program is a feasible and convenient and cost-effective method to enhance CF care for our patients.
