Concurrent validity between field tests and cardiopulmonary exercise testing in patients with idiopathic pulmonary fibrosis.

Background: Maximal treadmill cardiopulmonary exercise testing is the gold standard for assessing functional capacity in patients with idiopathic pulmonary fibrosis (IPF).

Purpose: Primarily to investigate the concurrent validity between three field tests and cardiopulmonary exercise testing in these patients.

Methods: Patients performed the cardiopulmonary exercise testing, a six-minute walk test, an incremental shuttle walk test, and, the Glittre-ADL test.

Perception of patients with interstitial lung diseases submitted to inspiratory muscle training.

Background: Although inspiratory muscle training reduces dyspnea in patients with chronic respiratory diseases, it was not yet evaluated in a sample composed exclusively of patients with interstitial lung diseases.

Objective: To discuss the perception of patients with interstitial lung diseases about inspiratory muscle training intervention.

Methods: This is a qualitative study.
