Thoracic surgery is a primary intervention used in the treatment of diseases of the lungs, pleura, chest wall, and mediastinum. Following surgery, changes in lung function and associated clinical symptoms may occur due to both the surgical procedure itself and patient-specific factors, and these may present intraoperatively and/or postoperatively. These changes are primarily restrictive in nature and may include a characteristic reduction in lung volume, a decrease in functional residual capacity that may lead to atelectasis, slowed mucociliary clearance, gas exchange abnormalities, and especially reduced chest expansion on the operated side. Additionally, problems in surfactant production and diaphragmatic dysfunction may also arise. Furthermore, the use of surgical drains, the nature of the surgical procedure, the integrity of the remaining lung tissue after resection, and the limitations caused by enforced immobility can all contribute to the development of various postoperative complications. Preventing and/or managing these postoperative complications is essential for enabling the patient to return to functional life, reducing long-term healthcare utilization, and improving survival rates. For this reason, pulmonary rehabilitation is indicated after thoracic surgeries. One of the methods of delivering rehabilitation is telerehabilitation, which allows patients to access therapy remotely. In this study, however, the term Digital Physiotherapy, which is a more current and comprehensive term recommended by World Physiotherapy, will be used. In the literature review, it was observed that most postoperative studies following thoracic surgery focus on the in-hospital period, while studies conducted after discharge are usually of short duration. The aim of this study is to examine the effects of long-term physiotherapy delivered through digital methods following thoracic surgery.
