About this trial
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.

Treatments tested in this trial
Conventional Inspiratory Muscle Training
Other interventionConventional inspiratory muscle training will be performed without visual feedback or mobile application support. Training will be delivered using a threshold-loading inspiratory muscle training device at 40% of maximal inspiratory pressure, with three sets of ten breaths.
Visual Feedback-Assisted Inspiratory Muscle Training
Other interventionVisual feedback-assisted inspiratory muscle training will be performed using a threshold-loading inspiratory muscle training device connected to a smart adaptor and mobile application. The mobile application will provide visual feedback during training. Training will be performed at 40% of maximal inspiratory pressure, with three sets of ten breaths. Application-derived data, including the number of successful breaths, total training duration, and total number of breaths, will be recorded.

Trial outcomes
Primary outcomes
1
Exercise Motivation
Exercise motivation will be assessed using the Exercise Motivation Scale after each inspiratory muscle training condition. The scale includes subdomains related to negative attitudes and thoughts, positive perspective and health, and physical appearance and health. Higher scores indicate higher exercise motivation. Scores obtained after conventional inspiratory muscle training and visual feedback-assisted inspiratory muscle training will be compared.
Time frame
Immediately after each intervention on postoperative day 1-2.Secondary outcomes
1
Dyspnea Perception
Dyspnea perception will be assessed using the Modified Borg Scale before and after each inspiratory muscle training condition. The scale is used to evaluate perceived breathlessness, with higher scores indicating greater dyspnea severity. This scale ranges from 0 to 10, where 0 indicates no dyspnea and 10 indicates maximal or very severe dyspnea. Changes in dyspnea perception will be compared between conventional inspiratory muscle training and visual feedback-assisted inspiratory muscle training.
Time frame
Before and immediately after each intervention on postoperative day 1-2.2
System Usability
The usability of the conventional inspiratory muscle training and visual feedback-assisted inspiratory muscle training system will be assessed using the System Usability Scale after the inspiratory muscle training session. The System Usability Scale is a 10-item questionnaire scored from 0 to 100, where 0 indicates the lowest perceived usability and 100 indicates the highest perceived usability. Higher scores indicate a better outcome, reflecting greater perceived usability of the system.
Time frame
Immediately after each intervention on postoperative day 1-2.3
Respiratory Muscle Strength
Respiratory muscle strength will be assessed preoperatively by measuring maximal inspiratory pressure and maximal expiratory pressure using a mouth pressure device. These measurements will be used to determine the training intensity and to characterize baseline respiratory muscle function.
Time frame
Preoperative day, one day before surgery.4
Patient Satisfaction
Patient satisfaction with each inspiratory muscle training condition will be evaluated using 0-10 rating scales. Participants will be asked to rate perceived training difficulty, willingness to continue training, and perceived benefit from the training. Scores will be compared between conventional inspiratory muscle training and visual feedback-assisted inspiratory muscle training.
Time frame
Immediately after each intervention on postoperative day 1-2.Sponsors and contacts
