Effectiveness of Respiratory Muscle Training with a Mobile Application After Lobectomy

Not Applicable

Not yet recruiting

• Conditions: Video Assisted Thoracic Surgery (VATS); Thoracic Surgery; Respiratory Muscle; Lung Cancer (NSCLC)

• Registration Number: NCT06813144
• Lead Sponsor: Hacettepe University

Brief Summary

It has been observed that there are negative effects on respiratory muscle strength following lobectomy. This has led to the necessity of respiratory muscle training to mitigate these adverse effects. Most studies conducted so far focus on the late postoperative period, and there are only a few studies evaluating the effectiveness of early postoperative inspiratory muscle training (IMT). It is believed that this method could be useful for facilitating patient follow-up and increasing patient motivation through visual feedback.

Detailed Description

It has been observed that there are negative effects on respiratory muscle strength following lobectomy. This has led to the necessity of respiratory muscle training to mitigate these adverse effects. Most studies conducted so far focus on the late postoperative period, and there are only a few studies evaluating the effectiveness of early postoperative inspiratory muscle training (IMT). Additionally, there is currently no study assessing the effectiveness of IMT using a smart adapter in patients who have undergone lobectomy. It is believed that this method could be useful for facilitating patient follow-up and increasing patient motivation through visual feedback. The aim of this study is to examine the changes in respiratory muscle strength and exercise capacity in patients after lobectomy via VATS, comparing classical IMT, mobile application-supported IMT, and a control group that does not receive IMT.

Primary Outcome Measures

Name	Time	Method
Inspiratory muscle strength	Measurements will be performed before surgery (the day before surgery), at discharge and during the follow-up period after surgery (10-15 days after discharge).	Respiratory muscle strength will measure by measuring mouth pressure and using maximal inspiratory pressure (MIP) values.
Expiratory muscle strength	Measurements will be performed before surgery (the day before surgery), at discharge and during the follow-up period after surgery (10-15 days after discharge).	Respiratory muscle strength will measure by measuring mouth pressure and using maximal expiratory pressure (MEP) values.

Secondary Outcome Measures

Name	Time	Method
Functional exercise capacity	Evaluations will be made before surgery (the day before surgery) and during the follow-up period (10-15 days after discharge).	6-minute walk test (6MWT) will be used to evaluate functional exercise capacity.
Postoperative Pulmonary Complications	Postoperative first-fifth days.	Postoperative pulmonary complications will be evaulate by Melbourne Group Scale. If more than 4 parameters are positive, it will be considered as having postoperative pulmonary complication.
Exercise Motivation	The evaluation will be made during the control period (10-15 days after discharge).	Exercise Motivation Attitude Scale will be used. This scale consists of 3 sub-dimensions (negative attitude and thought/positive view and health/physical appearance and health).
Dyspnea Level	An evaluation will be made in the preoperative (the day before surgery) and control period (10-15 days after discharge).	Modified Borg Scale will be used to evaluate dyspnea.
Quality of Life	The evaluation will be made during the preoerative (the day before surgery) and control (10-15 days after discharge) period.	SF-12 Quality of Life Scale will be used to assess quality of life.
Physical Performance	Evaluations will be made in the preoperative (the day before surgery) and control (10-15 days after discharge) periods.	The Short Physical Performance Battery, a frequently used test in cardiovascular and pulmonary diseases, will be used.
