Reliability and Validity of Maximal Respiratory Pressures.

Background: Maximal respiratory pressure is used to assess the inspiratory and expiratory muscles strength by using maximal inspiratory pressure (P) and maximal expiratory pressure (P). This study aimed to summarize and evaluate the reliability and validity of maximal respiratory pressure measurements.

Methods: This systematic review followed the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) recommendations and was reported by using the PRISMA checklist.

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.
