Abstract
BACKGROUND: Reduced cardiorespiratory fitness levels are associated with increased short-term complications after surgery, and potentially exert long-lasting effects on the postoperative lives, work and educational pursuits of patients. Currently, research suggests that lifestyle interventions, such as preoperative physical exercise undertaken by patients themselves, may improve patients' cardiopulmonary fitness and reduce post-operative complications. This study aims to investigate the effectiveness and feasibility of a remote medical supervision model for prehabilitation exercise in patients undergoing thoracoscopic lung tumour resection surgery. METHODS/DESIGN: All enrolled patients will participate in a 4-week pre-operative exercise intervention to improve their cardiorespiratory fitness. During this period, patients will wear wearable devices and exercise at home based on exercise prescriptions. The exercise prescription comprises aerobic exercise (three times a week or more), muscle strengthening exercise (twice a week or more), and respiratory muscle exercise (once a day). The primary aim is to investigate whether baseline VO(2)max could be improved following a 4-week preoperative exercise program. Secondary objectives include changes in forced expiratory volume in 1 s and forced vital capacity, degree of acceptance of the technology, quality of life, handgrip strength, postoperative complication rate and length of hospital stay. DISCUSSION: This study aims to evaluate the influence of preoperative prehabilitation exercises in a telemedicine active supervision mode in patients undergoing thoracoscopic lung tumour resection. As such, results of this trial might have some impact on future implementations of group- and home-based prehabilitation exercises in lung cancers. TRIAL REGISTRATION: This study was approved by the Medical Ethics Committee of Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology (approval number: TJ-IRB20220564) with registration at ClinicalTrials.gov (identifier: NCT05608759).
