Brief Summary

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.

Conditions

VATS; Respiratory Muscles; Exercise Training; Lung Cancer (NSCLC); Lobectomy

Outcome Measures

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.

  Immediately after each intervention on postoperative day 1-2.

Secondary Outcomes (5)

• Dyspnea Perception

  Before and immediately after each intervention on postoperative day 1-2.

• System Usability

  Immediately after each intervention on postoperative day 1-2.

• Respiratory Muscle Strength

  Preoperative day, one day before surgery.

• Patient Satisfaction

  Immediately after each intervention on postoperative day 1-2.

• Training Performance Data Recorded by the Mobile Application

  During the visual feedback-assisted intervention on postoperative day 1-2.

Study Arms (2)

Conventional IMT Followed by Visual Feedback-Assisted IMT

EXPERIMENTAL

Participants randomized to this arm will first receive conventional inspiratory muscle training without visual feedback. After a rest period of at least two hours, they will receive visual feedback-assisted inspiratory muscle training using a smart adaptor connected to a mobile application. Both training sessions will be performed using a threshold-loading inspiratory muscle training device at 40% of maximal inspiratory pressure, with three sets of ten breaths.

Other: Conventional Inspiratory Muscle Training; Other: Visual Feedback-Assisted Inspiratory Muscle Training

Interventions

Visual Feedback-Assisted Inspiratory Muscle Training OTHER

Visual 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.

Conventional IMT Followed by Visual Feedback-Assisted IMT; Visual Feedback-Assisted IMT Followed by Conventional IMT

Conventional Inspiratory Muscle Training OTHER

Conventional 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.
