The Influence of Lung Function and Respiratory Muscle Strength on Quadriceps Muscle Fatigability in COPD Patients Under Long-term Oxygen Therapy.

Background: This research investigates quadriceps muscle fatigability (MF) in chronic obstructive pulmonary disease (COPD) patients with chronic respiratory failure (CRF) at different levels of lung obstruction [severe obstruction (SO)=FEV <50% and >30% versus very severe obstruction (VSO)=FEV ≤30%]. It explores the relationships between quadriceps MF and lung function, respiratory muscles, and oxygenation status.

Methods: A post hoc cross-over analysis in 45 COPD patients (20 SO and 25 VSO) undergoing long-term oxygen therapy was performed.

Upper-limb interval constant-load exercise in patients with COPD: a physiological crossover study.

Objective: Upper-limb exercise is recommended for patients with COPD, albeit there are limited data concerning the optimal modality to implement. We compared interval (INT-EX) to continuous (CONT-EX) upper-limb exercise in terms of exercise tolerance, ventilatory and metabolic responses when both conditions were sustained at an equivalent work rate.

Methods: 26 stable COPD patients undertook three upper-limb exercise sessions to initially establish peak work rate (PWR) an incremental exercise test and subsequently two equivalent work rate tests to the limit tolerance in balanced order: 1) INT-EX consisting of 30-s work at 100% PWR interspersed with 30-s work at 40% of PWR; and 2) CONT-EX at 70% PWR.

Hospital-Provider Company Network for Home Non-Invasive Ventilation: A Feasibility Pilot Study.

This study assessed the feasibility of implementing a hybrid hospital-provider company (PC) clinical pathway for patients with chronic respiratory failure (CRF) through the adaptation and follow-up of non-invasive ventilation (NIV). Over a 3-month period, a PC physiotherapist case manager oversaw the adaptation process, making adjustments as necessary, using remote monitoring and home visits. Outcome measures, including the number of patients enrolled, serious adverse events, hospitalizations, survival rates, professional time allocation, NIV adherence, nocturnal apnea-hypopnea, and oxygen saturation, Δ arterial carbon dioxide pressure (PaCO), dyspnea, Short Physical Performance Battery (SPPB), exercise tolerance, quality of life, physical activity, and patient satisfaction, were collected.

Comparison among three different follow-up models for obstructive sleep apnea syndrome patients: focus on the physiotherapist's role.

In obstructive sleep apnea syndrome (OSAS) subjects different follow-up modalities have been proposed to improve adherence to the continuous positive airway pressure (CPAP) device. This retrospective study compares three different health professional approaches dedicated to caring OSAS patients in three consecutive follow-up periods of 15 months each. The three different follow-up models are: i) physician-oriented follow-up (P-F); ii) physiotherapist-oriented follow-up (PT-F); and iii) tele-titration plus PT-oriented follow-up (TT-PT-F).

Airflow grades, outcome measures and response to pulmonary rehabilitation in individuals after an exacerbation of severe chronic obstructive pulmonary disease.

Background: Individuals with COPD may be staged according to symptoms and exacerbation history (GOLD groups: A-D) and on airflow obstruction (GOLD grades: 1-4). Guidelines recommend pulmonary rehabilitation (PR) for these individuals, including those recovering from an exacerbation (ECOPD) OBJECTIVE: To evaluate whether in individuals with clinically severe COPD, recovering from an ECOPD, the effect size of an in-hospital PR program would be affected by airflow severity grades and assessed outcome measures.

Methods: Retrospective, multicentre study.

Effectiveness of pulmonary rehabilitation in individuals with Chronic Obstructive Pulmonary Disease according to inhaled therapy: The Maugeri study.

Background And Aim: Real-life studies report discordant prescribing of inhaled triple therapy (TT) among individuals with COPD. Guidelines recommend pulmonary rehabilitation (PR) for persistent breathlessness and/or exercise limitation. This real-life study aimed to assess the effects of in-patient PR in individuals under TT as compared to other inhaled therapies (no TT).

Relationship between perceived and neuromuscular fatigue in COPD patients with chronic respiratory failure with long-term oxygen therapy: a cross-sectional study.

Purpose: To evaluate perceived fatigue (PF) and neuromuscular fatigue (NMF) in patients with COPD and chronic respiratory failure (CRF) on long-term oxygen therapy (CRF-COPD group), and the relationships between PF, NMF, patient's characteristics, comparing severe patients with COPD to patients without CRF (COPD group).

Methods: This cross-sectional study compared 19 CRF-COPD patients with 10 COPD patients attending a rehabilitation program. PF was determined by Fatigue Severity Scale (FSS), while dyspnea by the Barthel Dyspnea Index (BDI).

In-Patient Trajectories and Effects of Training in Survivors of COVID-19-Associated Acute Respiratory Failure.

Background: Pulmonary rehabilitation (PR) is useful in survivors of COVID-19-associated acute respiratory failure (ARF). The aim of this retrospective study on in-patient PR was to report rehabilitative trajectories and effects of cycle training.

Methods: According to the Short Physical Performance Battery (SPPB) score at admission (T0), participants were allocated to stage 1 (SPPB < 6), stage 2 (SPPB ≥ 6 and < 10), or stage 3 (SPPB ≥ 10) and performed increasing level of activities from passive exercises to free walking, balance exercises, strength exercises, and tailored cycle-ergometer endurance training.

Respiratory rehabilitation for patients with COVID-19 infection and chronic respiratory failure: a real-life retrospective study by a Lombard network.

The Lombardy region has been one of the areas most affected by the COVID-19 pandemic since the first months of 2020, providing real-life experiences in the acute phase. It is unclear how the respiratory rehabilitation network responded to this emergency. The aims of this retrospective study were: i) to analyze clinical, functional, and disability data at admission; ii) describe assessment tools and rehabilitative programs; iii) evaluate improvement after rehabilitation.
