Acute Effects of Visual Feedback-Assisted Inspiratory Muscle Training After Lobectomy

This study aims to evaluate the acute effects of inspiratory muscle training performed with and without a mobile application providing visual feedback on exercise motivation, patient adherence, dyspnea perception, usability, and patient satisfaction in lung cancer patients undergoing lobectomy via video-assisted thoracic surgery. Participants will perform conventional inspiratory muscle training without visual feedback in the morning on postoperative day 1 after transfer to the ward. After at least two hours of rest, the same exercise protocol will be repeated with a smart adaptor connected to a mobile application to provide visual feedback. Inspiratory muscle training will be performed using a threshold-loading device at 40% of maximal inspiratory pressure, with three sets of ten breaths. Outcomes will be assessed before and/or after each session as appropriate.
