RESUMEN
BACKGROUND: Emerging data suggest a spectrum of pulmonary complications from COVID-19, ranging from dyspnea to difficult ventilator weaning and fibrotic lung damage. Prolonged hospitalization is known to significantly affect activity levels, impair muscle strength and reduce cardiopulmonary endurance. OBJECTIVE: To assess the feasibility and safety of inpatient pulmonary rehabilitation (PR) and to explore effects on functional capacity, physical performance, fatigue levels, and functional status. DESIGN: A prospective feasibility study. SETTING: Inpatient unit of a tertiary care hospital. PARTICIPANTS: Twenty-five hospitalized patients diagnosed with post-COVID-19 fibrosis referred for PR. INTERVENTION: Individualized PR intervention including breathing exercises, positioning, strengthening, functional training, and ambulation twice a day for 6 days a week. OUTCOME MEASURES: One-minute sit-to-stand test (STST), Short Physical Performance Battery (SPPB), Fatigue Assessment Scale (FAS), and Post-COVID-19 Functional Status Scale (PCFS). RESULTS: Twenty-five participants (19 males, 6 females) with a mean age of 54.2 ± 13.4 years were enrolled. Sixteen completed the two-point assessment after undergoing in-patient PR of mean duration 14.8 ± 9 days. PR led to a significant improvement in all functional outcomes that is, STST (from 7.1 ± 4.3 repetitions to 14.2 ± 2.1 repetitions, SPPB (from 5 ± 2.8 to 9.4 ± 1.5), FAS (from 33.3 ± 10.8 to 25.8 ± 4.7) at the p ≤ .001, and PCFS (from 3.6 ± 0.9 to 2.9 ± 1.2, p ≤ .05). CONCLUSION: Early initiation of PR for hospitalized patients with COVID-19 fibrosis was safe, well tolerated, and feasible and may improve functional status.
RESUMEN
BACKGROUND: Maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP) and maximum voluntary ventilation (MVV) measurements assist in determining the respiratory muscle strength and endurance. These determinants of respiratory muscles vary significantly by age, gender, height, and ethnic origin. Normative values for maximum respiratory pressures (MRPs) and MVV would aid in evaluating respiratory muscle function in athletes, estimating performance, and assisting in rehabilitation. In addition, the reference values may aid in determining the efficacy of therapeutic interventions in young people with chronic respiratory diseases. The purpose of this study was to see how respiratory muscle strength indices correlated with anthropometric and physical activity characteristics in young Arabs. METHODOLOGY: The study included 80 male volunteers and 85 female volunteers ranging in age from 18 to 30 years. MicroRPM was used to measure MIP and MEP, and pulmonary function test data, including MVV values, were recorded. All subjects completed the Global Physical Activity Questionnaire (GPAQ) and anthropometric measurements. Unpaired t-tests or Mann-Whitney U-tests were used to determine male-female differences. Using the Pearson correlation coefficient and Spearman Rho correlation coefficient tests, MIP and MEP values were correlated with body composition and physical activity. Using stepwise multiple linear regression analysis, the relationships between respiratory function (MVV, MIP, and MEP) and PFT values (FVC, FEV1, and FEV1/FVC), physical activity, and sedentary behavior were investigated. RESULTS: MIP, MEP, and MVV values were significantly lower in females than in males. MIP, MEP, and MVV values had a moderate correlation with forced vital capacity, forced expiratory volume in 1 second, and height, but not with weight, BMI, or GPAQ. Age, gender, and body mass index were found to be significant predictors of maximal respiratory pressures in a young Arab population. CONCLUSION: Maximum respiratory pressures and maximal voluntary ventilation were significantly lower in young Arabs than in other ethnic groups; these values were influenced by gender and height but not by levels of physical activity.
RESUMEN
Pulmonary Rehabilitation (PR) is an essential and comprehensive intervention recommended in the management of people with chronic respiratory diseases (CRD). Scientific evidence suggests significant health benefits with respect to repeated hospital admissions, exercise tolerance and Health Related Quality of Life (HRQoL). However, the uptake and completion of PR programs are globally low. In order to understand the factors contributing to underutilization of PR, it is important to review and recognize the barriers to PR program. A literature search was conducted on Medline (PubMed) database. After reviewing the title and abstracts, full text articles were scrutinized for their relevance. Twenty-two studies involving factors affecting the uptake, participation and completion of PR program were included in this review. Reported barriers to PR were healthcare system, healthcare professional and patient related factors. Primary factors related to healthcare system and healthcare professionals were fewer PR centers, accessibility inconvenience, lack of awareness of PR program, low knowledge of referral process and lack of interdisciplinary teamwork. Difficulties faced by patients to take up and/or to complete PR programs were lack of transportation, co-morbidities, lack of perceived benefits, socio-economic status and lack of funding facilities. Identified and reported barriers resulted into discontinuity between knowledge of health benefits and utilization of PR service for patients with CRDs. Addressing the barriers would accelerate the healthcare professionals' referral and patients to avail the health benefits of rehabilitation service.
