EFFICACY OF INSPIRATORY MUSCLE TRAINING ASSOCIATED WITH MANUAL TECHNIQUES IN INDIVIDUALS WITH GERD

The objective of this clinical trial is to investigate the efficacy of inspiratory muscle training (IMT) combined with manual techniques for the lower esophageal sphincter (MTLES) and diaphragmatic release (DRT) in patients with Gastroesophageal Reflux Disease (GERD). The main questions it aims to answer are:

1. If the combination of IMT, DRT, and MTLES can improve GERD symptoms and patients' quality of life. 2. If the home-based IMT protocol, with weekly adjustments, and the manual techniques applied twice a week can have a positive impact on various clinical measures, such as pressure at the lower esophageal sphincter, reflux episodes, and quality of life.

The researchers will compare three groups: Group 1 (IMT), Group 2 (IMT + DRT + MTLES), and Group 3 (control, sham), to see if the group receiving IMT combined with DRT and MTLES shows greater improvements compared to the control group.

Participants will perform inspiratory muscle training at home, following a protocol adjusted weekly, and will receive manual techniques twice a week.
