This study aims to develop and evaluate an integrated perioperative management system based on wearable devices and a digital rehabilitation platform for patients with non-small cell lung cancer (NSCLC) undergoing thoracic surgery. By combining preoperative functional assessment using the six-minute walk test (6MWT), continuous perioperative physiological monitoring, and structured postoperative home-based digital rehabilitation, this randomized controlled trial will investigate whether the wearable-based digital management model improves short-term postoperative pulmonary function, functional recovery, and clinical outcomes compared with standard perioperative care.
