Muscle strength and mobility of individuals with COVID-19 compared with non-COVID-19 in intensive care.

Background: Critical illness may affect muscle strength and mobility.

Objectives: To compare muscle strength, mobility, and in intensive care unit (ICU)-acquired weakness (ICUAW) prevalence among individuals with COVID-19 and other critical illnesses; to identify factors associated with muscle strength, mobility, and length of stay in COVID-19; and to determine the Perme Intensive Care Unit Mobility Score (PICUMS) cut-off point for ICUAW.

Methods: We included individuals aged ≥18 in ICU who require mechanical ventilation.

Rib cage distortion and dynamic hyperinflation during two exercise intensities in people with COPD.

Background: The relationship between rib cage (RC) motion abnormalities, dynamic hyperinflation (DH), and exercise capacity in people with COPD is controversial.

Aim: To investigate RC distortion and operational chest wall volumes during moderate and high constant-rate exercises in people with COPD.

Methods: Seven male participants [median(Q1-Q3) age: 63(60.

Sustained maximal inspiration has similar effects compared to incentive spirometers.

Purpose: To compare the effects of flow incentive spirometer (FIS), volume incentive spirometer (VIS), and sustained maximal inspiration exercise (SMI) on breathing pattern, chest wall motion, and thoracoabdominal asynchrony.

Methods: Sixteen healthy adults aged 27.63 ± 5.

Chronic pain is associated with increased health care use among community-dwelling older adults in Brazil: the Pain in the Elderly (PAINEL) Study.

Background: Chronic pain is known to increase health care use in high-income countries, but in Brazil, little is known.

Objective: To investigate the association between chronic pain and health care use among Brazilian older adults and explore the relationship between pain severity and health care use.

Methods: This cross-sectional study was derived from the population-based study Frailty in Brazilian Older People-FIBRA.

Breathing exercises: influence on breathing patterns and thoracoabdominal motion in healthy subjects.

Background: The mechanisms underlying breathing exercises have not been fully elucidated.

Objectives: To evaluate the impact of four on breathing exercises (diaphragmatic breathing, inspiratory sighs, sustained maximal inspiration and intercostal exercise) the on breathing pattern and thoracoabdominal motion in healthy subjects.

Method: Fifteen subjects of both sexes, aged 23 ± 1.
