Effect of 12-week head-down strong abdominal breathing on cognitive function in patients with stable chronic obstructive pulmonary disease: a single-centre randomised controlled trial protocol

BackgroundPatients with chronic obstructive pulmonary disease (COPD) often suffer from a combination of mild cognitive impairment (MCI) and a significant reduction in their quality of life. In the exercise programme of pulmonary rehabilitation (PR), pulmonary rehabilitation intervention is often carried out by enhancing respiratory function. Strong abdominal breathing is a kind of breathing method, through which the diaphragm can be exercised, thereby enhancing the deflection distance of the diaphragm during breathing and improving respiratory function. The inversion trainer can meet the different angles of head-down training and also has the characteristics of low cost, easy to operate, and use a wide range of scenarios. According to currently available data, strong abdominal breathing in combination with head-down position has not yet been used in pulmonary rehabilitation in this type of rehabilitation programme. It is valuable to use this device to study PR of cognitive function in patients with COPD.MethodsThis study was a 12-week single-centre randomised controlled trial and blinding the assessors and data processors of the test. Recruitment is planned for January 1, 2024. It is expected that 81 patients with stable COPD combined with MCI will be recruited and randomly assigned to the head-down strong abdominal breathing group (HG), the fitness qigong eight-duanjin group (BDJ), and the control group (CG) in a 1:1:1 ratio. Using fNIRS (functional near-infrared spectroscopy) to assess brain oxygen availability before and after pulmonary rehabilitation in three periods: before, during and after the intervention. Cognitive functioning is also assessed using the Overall Cognitive Assessment Scale, the Specific Cognitive Functioning Assessment Scale and the Cognitive Behavioural Ability Test.Trial registrationThe Specialised Committee on Scientific Research and Academic Ethics of the Academic Committee of Anqing Normal University approved the project (ANU2023001). China Clinical Trial Registry approved the study (ChiCTR2300075400) with a registration date of 2023/09/04.DiscussionThe aim of this study was to explore novel exercise rehabilitation methods to improve cognitive function in COPD patients. It results in a lower financial burden and higher participation in pulmonary rehabilitation and improves the quality of survival of patients with COPD.

Body Mass Index and Thoracic Expansion in Post-COVID Dyspnea: A Secondary Analysis.

Dyspnea secondary to lung impairment can persist following the acute phase of COVID-19. Thoracic expansion measurements have been used as a diagnostic tool to evaluate chest wall mobility, respiratory function, and the effects of respiratory muscle strength training. Changes in chest wall mobility may occur because of altered chest biomechanics in individuals with respiratory diseases and an elevated body mass index (BMI). The purpose of this secondary analysis was to evaluate whether BMI influences thoracic expansion or forced expiratory volume over 1 second (FEV1) in individuals with persistent dyspnea following COVID-19. This study assessed the relationship between BMI and thoracic expansion, pulmonary symptoms, and exercise capacity following a home-based pulmonary rehabilitation intervention. A secondary data analysis was conducted with a sample of 19 adults with persistent dyspnea following COVID-19 infection who participated in a 12-week, home-based pulmonary rehabilitation study. Participants received expiratory muscle strength training devices and were instructed to perform pulmonary rehabilitation exercises three times per week over the study period. Pulmonary function, pulmonary symptoms, exercise capacity, and BMI measurements were collected. For analysis, study participants were divided into obese (BMI > 30 kg/m2) or nonobese (BMI < 30 kg/m2) categories. Correlations using the change scores from baseline to 12 weeks between thoracic expansion, FEV1, pulmonary symptoms, and exercise capacity were assessed. In addition, the minimal detectable change (MDC) in thoracic expansion was explored. Thoracic expansion was significantly improved after 12 weeks of training (p = .012) in the nonobese group. There was a significant correlation between the change in walking distance and pulmonary symptoms (r = -.738, p < .001) and in thoracic expansion (r = .544, p = .020), and walking distance, when controlling for BMI, but no change in FEV1. Average MDC was 1.28 for inspiration and 0.91 for expiration. Measurements of thoracic expansion were significantly lower in post-COVID individuals with an increased BMI. Individuals with persistent dyspnea and a higher BMI may require additional measures to increase chest mobility or to detect pulmonary changes following COVID-19.

Safety and feasibility of Pulmonary Rehabilitation in patients hospitalized with post-COVID-19 fibrosis: A feasibility study.

Emerging data suggests 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 cardio-pulmonary endurance. 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. A prospective feasibility study. Inpatient unit of a tertiary care hospital. Twenty-five hospitalized patients diagnosed with post-COVID-19 fibrosis referred for pulmonary rehabilitation (PR). Individualized PR intervention including breathing exercises, positioning, strengthening, functional training and ambulation twice a day for six days a week. One minute Sit to Stand Test (STST), Short Physical Performance Battery (SPPB), Fatigue Assessment Scale (FAS) and Post-COVID-19 Functional status Scale (PCFS). Twenty-five participants (males-19, females-6) with a mean age of 54.25 ± 13.36 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 i.e., 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 value ≤0.001 and PCFS (from 3.6 ± 0.9 to 2.9 ± 1.2, p value ≤0.05). Early initiation of PR for hospitalized patients with COVID-19 fibrosis was found to be safe, well-tolerated and feasible and may improve functional status. This article is protected by copyright.

A Kano model-based demand analysis and perceived barriers of pulmonary rehabilitation interventions for patients with chronic obstructive pulmonary disease in China.

Pulmonary rehabilitation (PR) has been recognized to be an effective therapy for chronic obstructive pulmonary disease (COPD). However, in China, the application of PR interventions is still less promoted. Therefore, this cross-sectional study aimed to understand COPD patients' intention to receive PR, capture the potential personal, social and environmental barriers preventing their willingness of receiving PR, and eventually identify demanding PR services with the highest priority from patients' point of view. In total 237 COPD patients were recruited from 8 health care facilities in Zhejiang, China. A self-designed questionnaire was applied to investigate patients' intention to participate in PR and potentially associated factors, including personal dimension such as personal awareness, demographic factors, COPD status and health-related literacy/behaviors, as well as social policies and perceived environmental barriers. The demand questionnaire of PR interventions based on the Kano model was further adopted. Among the 237 COPD patients, 75.1% of COPD patients were willing to participate in PR interventions, while only 62.9% of the investigated patients had heard of PR interventions. Over 90% of patients believed that the cost of PR services and the ratio of medical insurance reimbursement were potential obstacles hindering them from accepting PR services. The multiple linear regression analysis indicated that the PR skills of medical staff, knowledge promotion and public education levels of PR in the community, patients' transportation concerns and degree of support from family and friends were significantly associated with willingness of participation in PR interventions. By using the Kano model, the top 9 most-requisite PR services (i.e., one-dimensional qualities) were identified from patients' point of view, which are mainly diet guidance, education interventions, psychological interventions and lower limb exercise interventions. Subgroup analysis also revealed that patients' demographics, such as breathlessness level, age, education and income levels, could influence their choice of priorities for PR services, especially services related to exercise interventions, respiratory muscle training, oxygen therapy and expectoration. This study suggested that PR-related knowledge education among patients and their family, as well as providing basic package of PR services with the most-requisite PR items to COPD patients, were considerable approaches to promote PR attendance in the future.

Pulmonary Rehabilitation Strategies for the Treatment of Pneumoconiosis: A Narrative Review.

Pneumoconiosis is a collection of lung diseases caused by inhaling mineral dust that poses an important risk to public health worldwide. Effective clinical treatments are currently limited, but pulmonary rehabilitation (PR) has shown promise in treating respiratory diseases. This review aims to assess the effectiveness of PR strategies for treating pneumoconiosis. We searched research studies that investigated the effectiveness of PR interventions for pneumoconiosis patients in international scientific databases and comprehensively reviewed PR strategies for the treatment of pneumoconiosis. Pneumoconiosis patients are increasingly being treated with a multimodal PR program. PR interventions could save healthcare costs, reduce dyspnea, improve exercise performance, and enhance overall health-related quality of life in patients with pneumoconiosis. PR interventions are effective in improving respiratory function and quality of life in patients with pneumoconiosis. However, further research is needed to determine the optimal PR strategies for pneumoconiosis patients and to investigate the long-term effects of these interventions.

Perspectives of Patients With Chronic Respiratory Diseases and Medical Professionals on Pulmonary Rehabilitation in Pune, India: Qualitative Analysis.

Chronic respiratory diseases (CRDs) contribute significantly to morbidity and mortality worldwide and in India. Access to nonpharmacological options, such as pulmonary rehabilitation (PR), are, however, limited. Given the difference between need and availability, exploring PR, specifically remotely delivered PR, in a resource-poor setting, will help inform future work. This study explored the perceptions, experiences, needs, and challenges of patients with CRDs and the potential of and the need for PR from the perspective of patients as well as medical professionals involved in the referral (doctors) and delivery (physiotherapists) of PR. In-depth qualitative semistructured interviews were conducted among 20 individuals diagnosed with CRDs and 9 medical professionals. An inductive thematic analysis approach was used as we sought to identify the meanings shared both within and across the 2 participant groups. The 20 patients considered lifestyle choices (smoking and drinking), a lack of physical activity, mental stress, and heredity as the triggering factors for their CRDs. All of them equated the disease with breathlessness and a lack of physical strength, consulting multiple doctors about their physical symptoms. The most commonly cited treatment choice was an inhaler. Most of them believed that yoga and exercise are good self-management strategies, and some were performing yoga postures and breathing exercises, as advised by friends or family members or learned from a televised program or YouTube videos. None of them identified with the term "pulmonary rehabilitation," but many were aware of the exercise component and its benefits. Despite being naive to smartphone technology or having difficulty in reading, most of them were enthusiastic about enrolling in an application-based remotely delivered digital PR program. The 9 medical professionals were, however, reluctant to depend on a PR program delivered entirely online. They recommended that patients with CRDs be supported by their family to use technology, with some time spent with a medical professional during the program. Patients with CRDs in India currently manage their disease with nonguided strategies but are eager to improve and would benefit from a guided PR program to feel better. A home-based PR program, with delivery facilitated by digital solutions, would be welcomed by patients and health care professionals involved in their care, as it would reduce the need for travel, specialist equipment, and setup. However, low digital literacy, low resource availability, and a lack of expertise are of concern to health care professionals. For India, including yoga could be a way of making PR "culturally congruent" and more successful. The digital PR intervention should be flexible to individual patient needs and should be complemented with physical sessions and a feedback mechanism for both practitioners as well as patients for better uptake and adherence.

Ultrasonic Evaluation of Diaphragm in Patients with Systemic Sclerosis.

The diaphragm is the most important muscle in respiration. Nevertheless, its function is rarely evaluated. Patients with systemic sclerosis (SSc) could be at risk of diaphragmatic dysfunction because of multiple factors. These patients often develop interstitial lung disease (SSc-ILD) and earlier studies have indicated that patients with different ILDs have decreased diaphragmatic mobility on ultrasound (US). This study aimed to evaluate diaphragmatic function in SSc patients using US with regard to the ILD, evaluated with the Warrick score on high-resolution computed tomography (HRCT), and to investigate associations between ultrasonic parameters and dyspnea, lung function, and other important clinical parameters. In this cross-sectional study, we analyzed diaphragm mobility, thickness, lung function, HRCT findings, Modified Medical Research Council (mMRC) dyspnea scale, modified Rodnan skin score (mRSS), autoantibodies, and esophageal diameters on HRCT in patients with SSc. Fifty patients were enrolled in the study. Patients with SSc-ILD had lower diaphragmatic mobility in deep breathing than patients without ILD. The results demonstrated negative correlations between diaphragmatic mobility and mMRC, mRSS, anti-Scl-70 antibodies, esophageal diameters on HRCT, and a positive correlation with lung function. Patients with SSc who experience dyspnea should be evaluated for diaphragmatic dysfunction for accurate symptom phenotyping and personalized pulmonary rehabilitation treatment.

Efficacy of Pulmonary Rehabilitation in Post-COVID-19: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis examines how pulmonary rehabilitation impacts in patients suffering from subacute and long COVID-19 infections, gauging enhancements in of dyspnea, physical function, quality of life, psychological state (anxiety and depression), and fatigue. Three electronic databases (PubMed, Web of Science, Cochrane Library) were systematically searched for full-text articles published from inception to January 2023. Randomized, quasi-experimental, and observational studies were included, with adults diagnosed with subacute or long COVID-19 who received pulmonary rehabilitation as intervention. Outcomes related to dyspnea, physical function, quality of life, fatigue, and psychological status were included. Risk of bias was assessed with Cochrane Risk of Bias Tool for Randomized Controlled Trials and Risk of bias in non-randomized studies of intervention. The review was registered before starting in PROSPERO (CRD: 42022373075). Thirty-four studies were included, involving 1970 patients with subacute and long COVID-19. The meta-analysis demonstrated moderate to large effects on dyspnea, physical function, quality of life, and depressive symptoms compared to usual care intervention. No significant differences were found in fatigue compared to usual care, nor in anxiety levels after pulmonary rehabilitation intervention. Pulmonary rehabilitation has the potential to improve health outcomes in patients with subacute and long COVID-19. However, due to the high risk of bias of included studies, conclusions should be taken with caution.

Modern approaches of rehabilitation in COPD patients

Chronic Obstructive Pulmonary Disease (COPD) presents a significant challenge to public health, impairing the quality of life for affected individuals. Traditionally, the management of COPD primarily involved pharmacological interventions and symptom management, but a shift towards comprehensive rehabilitation programs has been observed in recent times. This study focuses on exploring these modern approaches to COPD rehabilitation, including exercise training, education, psychosocial support, and self-management strategies. By emphasizing patient-centered and multidisciplinary methodologies, modern rehabilitation approaches aim to address the individual needs of COPD patients. Previous studies affirm the positive impacts of these comprehensive programs, including improved exercise capacity, reduced symptoms, and enhanced overall well-being. This current investigation aims to further analyze the effects of various pulmonary rehabilitation methods on COPD management within a modern medical context. By critically evaluating literature and research databases like SCOPUS, PubMed, SciELO, Google Scholar, and Cochrane Library, this study seeks to provide unique insights into the efficacy and benefits of pulmonary rehabilitation for COPD patients. The implications of this research could contribute significantly to evidence-based practices, assisting healthcare professionals in optimizing the selection and implementation of pulmonary rehabilitation interventions for improved patient outcomes.

Chronic Obstructive Pulmonary Disease Access and Adherence to Pulmonary Rehabilitation Intervention (CAPRI): Protocol for a randomized controlled trial and adaptations during the COVID-19 pandemic

BackgroundPulmonary rehabilitation (PR) is the standard of care for chronic obstructive pulmonary disease (COPD) management. However, significant barriers limit access and adherence to PR and alternatives are needed. The purpose of this randomized controlled trial is to test the efficacy of a web-based, pedometer-mediated intervention to increase physical activity (PA) for persons with COPD who decline PR or meet U.S. guidelines for referral to PR but have not participated (CAPRI-1). In addition, we will test whether the intervention maintains PA following PR in an exploratory aim (CAPRI-2). MethodsParticipants with COPD (N = 120) will be recruited and randomized 1:1 to a 12-week web-based, pedometer-mediated intervention or usual care (UC) (CAPRI-1). The intervention provides: 1) objective monitoring of walking and iterative feedback, 2) individualized step-count goals, 3) motivational messages and educational content, and 4) an online community. The primary outcome is change in daily step count from baseline to 12 weeks. Secondary outcomes include: (a) exercise capacity; (b) self-reported PA; (c) PA intensity; (d) exercise self-regulatory efficacy, (e) health-related quality of life, (f) dyspnea, (g) depression symptoms, and (h) healthcare utilization. CAPRI-2 will test whether participants (N = 96) assigned to the intervention following PR completion show greater maintenance of daily step count compared to UC at 3, 6, 9, and 12 months. DiscussionIf the intervention is efficacious, it may be an alternative for those who cannot attend PR or a maintenance program following completion of conventional PR. We also present adaptations made to the protocol in response to the COVID-19 pandemic.

Effectiveness of patient decision aid supported shared decision-making intervention in in-person and virtual hybrid pulmonary rehabilitation in older adults with chronic obstructive pulmonary disease: A pilot randomized controlled trial

Tele-pulmonary rehabilitation is increasingly advocated but cannot completely substitute for in-person services for chronic conditions. Adherence to Pulmonary rehabilitation (PR) remains low in chronic obstructive pulmonary disease (COPD) patients. Shared decision-making (SDM) promotes patients' participation in PR decisions and helps patients and healthcare providers to jointly make decisions that patients are informed and aligned with patient preferences and values, which are critical for patient adherence to PR. This study aimed to develop a hybrid in-person and virtual model of home-based PR services for older COPD patients and study the effectiveness of the patient decision aid (PDA)-supported recurring SDM intervention on patient adherence to PR, rehabilitation outcomes, and decision-related outcomes, as well as to explore the mechanisms of the intervention on PR adherence. A total of 78 older COPD patients were randomly assigned to the PR group (n = 39) or PDA-PR group (n = 39). Both groups were conducted hybrid in-person and virtual PR intervention for 3 months. The primary outcomes were patients' quality of life and PR adherence. The secondary outcomes were dyspnea symptoms, exercise self-efficacy, knowledge, and decision-related outcomes. A total of 72 participants completed the 3-month PR program. There were statistically significant differences in PR adherence (p = 0.033), COPD assessment test (CAT) scores (p = 0.016), PR knowledge (p < 0.001), decision self-efficacy (p < 0.001), decision conflict (p < 0.001), and decision regret scores (p = 0.027) between the two groups. The modified Medical Research Council Dyspnoea scale (mMRC) score was significantly decreased only in PDA-PR group (p = 0.011). No statistically significant differences were observed in St George's Respiratory Questionnaire (SGRQ) score (p = 0.078), Exercise Self-Regulatory Efficacy Scale (Ex-SRES) score (p = 0.29) and COPD knowledge (p = 0.086) between the two groups. PR value score had a significant effect on adherence to PR (p = 0.007) and CAT score (p = 0.028). PDA supported recurring SDM intervention was helpful in maintaining older COPD patients' PR adherence and had advantages in improving quality of life, enhancing PR knowledge, decision self-efficacy, and reducing decision conflict and decision regret, but did not improve SGRQ and Ex-SRES. PR value score influenced patients' rehabilitation adherence and quality of life. Chinese Clinical Trial Registry (ChiCTR): ChiCTR1900028563; http://apps.who.int/trialsearch/default.aspx.

Understanding the Patient Experience of Home-Based Pulmonary Rehabilitation With Health Coaching for COPD: A Qualitative Interview Study.

We recently reported the largest randomized trial of home-based pulmonary rehabilitation (PR) for Chronic Obstructive Pulmonary Disease (COPD) in the USA that showed improvement in all domains of quality of life, accelerometry-measured physical activity, and self-management. We aimed for an in-depth understanding of how patients experience complex, multi-component programs like to help uncover factors related to behavior change and to inform program scale-up in other populations. In addition, we used a theoretical framework to provide a structure for understanding patient experience in the larger context of behavior change interventions for patients with COPD. The parent trial was conducted with patients diagnosed with COPD who received care at an academic medical center and a community health system in the upper Midwest. The 12-week PR intervention included three video-guided exercises to be practiced daily, activity monitors, and weekly telephonic health coaching. Trial participants were eligible to participate in an individual interview about their experience if they completed the intervention within the prior 12 months. Individual interviews were conducted by telephone using a semi-structured guide. Analysis of verbatim transcripts followed an inductive thematic approach followed by deductive categorization and interpretation using a theoretical model (Capability, Opportunity, Motivation, Behavior [COM-B]) developed for linking intervention functions to aspects of behavioral change. Among 32 eligible program participants, 32 were approached, and 15 completed interviews between October 19th, 2021, and January 13th, 2022. The COM-B model and recommendations for program improvement were observed in the primary findings. Capability included the knowledge and physical ability by participating in the program, including participants' understanding of the exercises and their confidence in doing them despite physical limitations and fear of COPD exacerbation. Opportunity included the perceptions that the program was convenient due to being self-paced and in a home-based setting. Health coaching also provided support, social influence, and accountability. Motivation included a desire to feel better, improve health, and become more active and independent. Improvements in skills, mood, and attitudes from program participation further bolstered confidence and motivation, especially among participants concerned about completing the program at enrollment. Recommendations for improvement included varying activities/exercises to maintain interest. Participants provided unique insights into how they engaged with program components and the ways that the program fostered behavior change. It highlighted ways that health coaching bolstered skills and confidence among participants with the poorest function at program enrollment and how improved physical function and mood led to motivation. It also highlighted the roles of technology and telephonic support in a home-based program. Suggestions for improvement, including exercise variations, are consistent with efforts to design complex interventions that can meet diverse patients' needs.

Role of digital health in pulmonary rehabilitation and beyond: shaping the future.

Pulmonary rehabilitation (PR) is a cost-effective intervention with well-known benefits to exercise capacity, symptoms and quality of life in patients with chronic respiratory diseases. Despite the compelling evidence of its benefits, PR implementation is still suboptimal, and maintenance of PR benefits is challenging. To overcome these pitfalls, there has been a growing interest in developing novel models for PR delivery. Digital health is a promising solution, as it has the potential to address some of the most reported barriers to PR uptake and adherence (such as accessibility issues), help maintain the positive results following a PR programme and promote patients' adherence to a more active lifestyle through physical activity (tele)coaching. Despite the accelerated use of digital health to deliver PR during the coronavirus disease 2019 pandemic, there are still several factors that contribute to the resistance to the adoption of digital health, such as the lack of evidence on its effectiveness, low acceptability by patients and healthcare professionals, concerns about implementation and maintenance costs, inequalities in access to the internet and technological devices, and data protection issues. Nevertheless, the trend towards reducing technology costs and the higher availability of digital devices, as well as the greater ease and simplicity of use of devices, enhance the opportunities for future development of digitally enabled PR interventions. This narrative review aims to examine the current evidence on the role of digital health in the context of PR, including strengths and weaknesses, and to determine possible threats and opportunities, as well as areas for future work.

Clinical Rehabilitation Nursing of Patients with Chronic Obstructive Pulmonary Disease Based on Intelligent Medicine.

Chronic obstructive pulmonary disease (COPD) is a respiratory disease that can be treated and prevented. The purpose of this paper is to conduct a meta-analysis of clinical rehabilitation nursing of COPD patients based on intelligent medical care by constructing a suitable model so as to make the research on clinical nursing of COPD patients more effective. This paper first introduced the intelligent medical system, analyzed the clinical rehabilitation nursing of COPD patients, established the SCNet model suitable for this paper, and then used statistical algorithms to carry out the meta dynamic analysis of the clinical rehabilitation nursing for COPD patients. Through the analysis of the current situation of medical equipment and the comparison of models and statistical analysis, the experimental results showed that the pulmonary function indexes of the pulmonary rehabilitation treatment group and the conventional treatment group were improved after treatment compared with before treatment. Although on specificity metrics SCNet did not perform the best, it was about 1% lower than the best baseline model. However, the comprehensive performance of the SCNet model on Acc, Sen, F1-Score, and AP indicators showed that the model SCNet proposed in this paper had certain advantages, which was helpful for the clinical rehabilitation care of patients with COPD and could better assist doctors in treatment.

Pulmonary rehabilitation ameliorates regional lung function in chronic obstructive pulmonary disease: a prospective single-arm clinical trial.

BackgroundPulmonary rehabilitation (PR) is a widely recognized nonpharmacologic therapy for chronic obstructive pulmonary disease (COPD), but most of the current studies on whether PR can benefit COPD patients are based on the evaluation of symptoms and pulmonary function, which is limited to a certain extent. Because COPD is characterized by potential regional lung changes in morphology and pathophysiology, this study was designed to evaluate the effects of individualized PR on regional lung function in patients with stable COPD.MethodsIn this study, patients with stable COPD who met the criteria were included, and they were treated with PR for 2 weeks using the respiratory rehabilitation training instrument. The symptoms, and global and regional lung function before and after 2 weeks of PR treatment were evaluated using surveys, spirometry, and electrical impedance tomography (EIT), respectively. The spatial coefficient of variation (CV) of regional spirometry parameters were calculated to quantify spatial heterogeneity of lung function. Temporal inhomogeneity was determined by the regional expiration time.ResultsA total of 34 participants were recruited in this study, of whom 24 completed the PR. After 2 weeks of intervention, the modified Medical Research Council (mMRC) dyspnea scale and the COPD assessment test (CAT) score was significantly lower compared to those measured before the treatment (2.3±1.17 vs. 2.1±0.93, P=0.034; and 15.0±7.18 vs. 10.9±6.06, P<0.001, respectively). Global spirometry forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), FEV1 predicted percentage (%pred), and peak expiratory flow (PEF) were significantly better than they were pre-rehabilitation (2.1±0.86 vs. 2.3±0.90 L, P=0.018; 1.2±0.65 vs. 1.4±0.66 L, P=0.001; 46.8%±23.16% vs. 51.4%±24.41%, P<0.001; and 3.1±1.80 vs. 3.8±2.23 L/s, P=0.005, respectively). In addition, the CV for regional FEV1/FVC was significantly decreased after the PR treatment (0.26±0.161 vs. 0.17±0.077, P=0.002). Regional lung ventilation was more homogeneous and regional expiration time was shorter after 2 weeks of the PR treatment.ConclusionsTwo weeks of PR treatment can improve both spatial and temporal regional ventilation in COPD. In addition, EIT may be useful in developing individualized PR treatment program to improve regional lung function in COPD.

An overview of Cochrane systematic reviews for pulmonary rehabilitation interventions in people with chronic obstructive pulmonary disease: a mapping synthesis.

There is a global unmet need for rehabilitation to meet which the World Health Organization, in collaboration with Cochrane Rehabilitation, is developing the Package of Interventions for Rehabilitation with the aim of identifying rehabilitation interventions relevant to a range of key health conditions, including chronic obstructive pulmonary disease (COPD). The purpose of this paper is to describe the best available evidence on pulmonary rehabilitation interventions for people with COPD. An Overview of Cochrane Systematic Reviews (CSRs). Through the search strategy, COPD-related systematic reviews published from January 2009 to November 2021 were identified. Data were extracted on each reported outcome related to an intervention and judgements about the quality of evidence were made, using the GRADE approach. Seventeen reviews were analyzed, for a total of 314 primary studies that included 22,206 participants. CSRs provided information on the effectiveness of rehabilitation on functioning, activity, quality of life, anxiety, depression, mortality, and health care resource utilization. Our findings report that comprehensive pulmonary rehabilitation programs and water exercises improve the exercise capacity and quality of life (QoL) in people with COPD. Different exercise modalities, intensities, and settings for different muscle groups, breathing exercises, and counseling can improve exercise capacity, QoL, dyspnea, hospitalizations, and physical activity. It is uncertain whether breathing exercise, low-intensity exercise, neuromuscular electrical stimulation, and psychological intervention have an effect on exercise capacity, dyspnea, QoL, and physical activity. The protocol was registered on OSF (registration DOI: 10.17605/OSF.IO/8A26Q).

Pulmonary rehabilitation: A novel adjunct in management of obstructive sleep apnea.

Pulmonary rehabilitation (PR) is being used in the routine management of patients of obstructive sleep apnea (OSA) at some centers. However, the studies documenting benefits of PR in OSA lack standardization in terms of outcome measures. A study was hence planned to determine the efficacy of PR on exercise capacity, health related quality of life (HRQOL), day time sleepiness and sleep-quality of life (QOL) in patients of OSA. As a part of comprehensive therapy, patients diagnosed with OSA are managed with continuous positive airway pressure (CPAP), 8 weeks thrice weekly outpatient hospital-based PR and medical treatment at the Pulmonary Medicine Department, Government Medical College and Hospital, Chandigarh. However, some patients refuse for PR because of time constraints and travel issues. Patients with newly diagnosed OSA without co-existing respiratory disease, who agreed for the CPAP, PR and medical management were enrolled in group A. The patients who refused for PR but were ready for CPAP and medical management were enrolled in Group B; 30 patients were taken in each group. Exercise capacity, HRQOL, day time sleepiness and sleep-QOL were determined at baseline and at 8-weeks follow-up by 6-minute walk distance (6MWD), St. George's Respiratory Questionnaire (SGRQ), Epworth Sleepiness Scale (ESS) and Functional Outcomes of Sleep Questionnaire (FOSQ) and compared amongst the two groups. Four patients from group A were excluded as they did not complete PR; 26 patients from group A and 30 patients from group B were finally analyzed. At baseline, both groups were matched with respect to age, gender, apnea-hypopnea index (AHI), body mass index (BMI), FEV1%predicted, 6MWD, SGRQ, ESS and FOSQ. At follow up at 8 weeks, BMI, 6MWD, SGRQ, ESS and FOSQ improved significantly from baseline in group A (p<0.001). FEV1%predicted also improved but non significantly. In group B, FEV1%predicted, BMI, 6MWD, SGRQ, ESS and FOSQ score did not improve significantly from baseline. Mean improvement from baseline in BMI, 6MWD, SGRQ, ESS and FOSQ was significantly more in group A than group B (p<0.001, p<0.001, p=0.041, p<0.001 and p<0.001, respectively). PR, being beneficial, should be incorporated in standard management of OSA.

Effects of Pulmonary Rehabilitation on Systemic Inflammation and Exercise Capacity in Bronchiectasis: A Randomized Controlled Trial.

Bronchiectasis is a chronic condition that is becoming a global health concern. To examine the effects of pulmonary rehabilitation (PR) on systemic inflammation, exercise capacity, and quality of life in participants with bronchiectasis. Participants were randomized to receive PR (outpatient, three weekly sessions for 3 months) or control intervention (usual care + airway clearance therapy + breathing exercises). Data on laboratory (fibrinogen level) and patient-centered outcomes such as physical fitness [6-min walk test (6MWT)] and quality of life were collected. A total of 41 participants were evaluated (20 in the intervention group and 21 in the control group). The magnitude of change between baseline and the end of study was greater in the PR group than in the control group-the 6MWT distance increased by a mean of 54m (54 vs 12m; p < 0.01), fibrinogen showed a significant reduction (fibrinogen -92.8 versus -47.1mg/dl; p < 0.01), and quality of life improved according to Saint George's Respiratory Questionnaire (SGRQ) (-7.5 vs 3.2; p < 0.01), which exceeded the minimal clinically important difference of 4 points. PR effectively improved physical fitness, quality of life, and the degree of systemic inflammation, as reflected by changes in 6 MWT, fibrinogen levels and SGRQ scores. This study supports the inclusion of people with bronchiectasis in supervised PR programs.
