摘要:
Introduction: We evaluated the safety and feasibility of high-intensity interval training via a novel telemedicine ergometer (MedBIKE (TM)) in children with Fontan physiology. Methods: The MedBIKE (TM) is a custom telemedicine ergometer, incorporating a video game platform and live feed of patient video/audio, electrocardiography, pulse oximetry, and power output, for remote medical supervision and modulation of work. There were three study phases: (I) exercise workload comparison between the MedBIKE (TM) and a standard cardiopulmonary exercise ergometer in 10 healthy adults. (II) In-hospital safety, feasibility, and user experience (via questionnaire) assessment of a MedBIKE (TM) high-intensity interval training protocol in children with Fontan physiology. (III) Eight-week home-based high-intensity interval trial programme in two participants with Fontan physiology. Results: There was good agreement in oxygen consumption during graded exercise at matched work rates between the cardiopulmonary exercise ergometer and MedBIKE (TM) (1.1 +/- 0.5 L/minute versus 1.1 +/- 0.5 L/minute, p = 0.44). Ten youth with Fontan physiology (11.5 +/- 1.8 years old) completed a MedBIKE (TM) high-intensity interval training session with no adverse events. The participants found the MedBIKE (TM) to be enjoyable and easy to navigate. In two participants, the 8-week home-based protocol was tolerated well with completion of 23/24 (96%) and 24/24 (100%) of sessions, respectively, and no adverse events across the 47 sessions in total. Conclusion: The MedBIKE (TM) resulted in similar physiological responses as compared to a cardiopulmonary exercise test ergometer and the high-intensity interval training protocol was safe, feasible, and enjoyable in youth with Fontan physiology. A randomised-controlled trial of a home-based high-intensity interval training exercise intervention using the MedBIKE (TM) will next be undertaken.
