Pulmonary and Functional Rehabilitation Improves Functional Capacity, Pulmonary Function and Respiratory Muscle Strength in Post COVID-19 Patients: Pilot Clinical Trial

Does long COVID in people living with HIV resemble the functional phenotype of non-HIV individuals who had moderate or severe acute COVID-19? A retrospective cross-sectional study

Introduction

It has been postulated that individuals with long COVID have reduced exercise capacity, just as people living with HIV (PLWH), although having even lower exercise capacity. The extent to which long COVID in PLWH resembles long COVID in individuals who presented different COVID-19 phenotypes is unknown, so we aimed to determine if the long COVID profile in PLWH resembled the symptoms experienced by individuals with long COVID following mild/moderate or severe acute COVID-19, 2 years after the initial disease.

Material and methods

A pulmonary function test and a 6-min walk test (6MWT) were performed on adult individuals with PACS (Post-Acute COVID Syndrome) in 3 groups: COVID-19+PLWH (plwHCOV), mild/moderate COVID-19 (mmCOV); severe COVID-19 (seCOV).

Results

Sixty three individuals were included: plwHCOV (n = 12), mmCOV (n = 33) and seCOV (n = 18). Across all groups, males were predominant. BMI was 25 ± 3, 28 ± 4, and 32 ± 7 kg/m2 in plwHCOV, mmCOV, and seCOV, respectively (p = 0.003). The plwHCOV walked 545 m (±93) at the 6MWT, which was comparable to the mmCOV group (555 m ± 63) but significantly higher than the seCOV group (435 m ± 84) (p < 0.0001). The plwHCOV group had worse forced expiratory volume in 1st second (FEV1%, 80 ± 12) (p < 0.0001), forced vital capacity (FVC%, 83 ± 11) (p = 0.002) and FEV1/FVC (0.80 ± 0.1, p = 0.004) when compared to the seCOV group. Interestingly, PLWH had comparable 6MWT, FEV1, FVC, and FEV1/FVC results as mmCOV.

Conclusion

Our results indicate that even 2 years post-COVID-19 infection, PLWH exhibits significantly decreased spirometry compared to the seCOV group. Despite this lung function impairment, their functional capacity was similar to individuals with PACS following mild/moderate COVID-19.

Pulmonary and functional hallmarks after SARS-CoV-2 infection across three WHO severity level-groups: an observational study

Background

The manifestations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection range from flu-like symptoms to severe lung disease. The consequences of this inflammatory process impact overall function, which can be detected through both short- to long-term assessments. This study aimed to assess the pulmonary functional and structural characteristics of post-SARS-CoV-2 infection in patients with mild/moderate, severe, and critical clinical presentations.

Methods

An observational, analytical, and cross-sectional study was conducted between 2020 and 2022, including participants with a confirmed diagnosis of coronavirus disease (COVID)-19, with mild/moderate (G1), severe (G2), and critical (G3) clinical presentations, all evaluated at least 3 months after acute infection. Spirometry, impulse oscillometry, fractional exhaled nitric oxide (FeNO), chest computed tomography, the 6-min walk test (6MWT), hand grip strength, maximum inspiratory pressure, and maximum expiratory pressure were assessed.

Results

We enrolled 210 participants aged 18-70 years, 32.6% of whom were male, with older age observed in G3. The participants were grouped as follows: G1 (42.3%), G2 (25.7%), and G3 (31.9%). Percentage of predicted X5 differed between G1 and G2, being higher in G1. The percentage of predicted forced vital capacity (FVC) according to the Global Lung Function Initiative and its z-score were higher in G1. The FVC by Pereira was lower in G3 compared to G1. The percentage of predicted forced expiratory volume in 1 s (FEV1) by Pereira was also lower in G3. The Tiffeneau (FEV1/FVC) index was different among groups, increasing with disease severity. The percentage of predicted forced expiratory flow rate at 25-75% (FEF25-75%) of the FVC and FeNO were both higher in G2 than G1. Chest computed tomography revealed the presence of interstitial abnormalities, associated with disease severity. The respiratory muscle strength evaluation showed an association between higher maximum expiratory pressure values in G3 compared to G1, but no association with maximum inspiratory pressure was observed. The 6MWT distance covered decreased with increasing severity, with a lower percentage of predicted values in G3 compared to G1. The right-hand grip strength was also lower in G3 compared to G1.

Conclusion

Alterations in pulmonary and functional markers were observed in post-COVID-19 evaluations, increasing with disease severity, as seen in G2 and G3. These findings highlight the complexity of post-COVID-19 functional assessments, given the long-term pulmonary sequelae and the consequent impairment of functional capacity.

Effect of Continuous Positive Airway Pressure (CPAP) Mode on Lung Function, Exercise Tolerance, Vital Signs, and Dyspnea After Acute SARS-CoV-2 Infection

Background/Objectives: The coronavirus disease (COVID-19) pandemic was associated with an intense impact on health worldwide. Among the sequelae, it became necessary to clarify respiratory impairment related to lung function and aerobic capacity, as well as the treatment of curative and preventive measures of pulmonary involvement. In this context, this study aimed to compare vital signs, the sensation of dyspnea (Borg scale), lung function, and exercise tolerance before and after the use of non-invasive mechanical ventilation (NIV) in adults of both sexes after acute infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods: A cross-sectional analytical clinical study was performed with the inclusion of individuals who had been diagnosed with COVID-19 at least three months before data collection. Individuals were evaluated for vital signs (heart rate and peripheral oxygen saturation), Borg scale, spirometry, and submaximal exercise protocol of two minutes of the step test before and after receiving NIV in ventilation mode by continuous positive airway pressure of 6 cm H2O for 30 min. Results: A total of 50 participants were enrolled and grouped as a mild (N = 25) or severe (N = 25) clinical phenotype during SARS-CoV-2 infection according to the criteria of the World Health Organization. In our data, the forced vital capacity (p < 0.001), the ratio between the forced expiratory volume in the first one second to the forced vital capacity and the forced vital capacity (p = 0.020), and the two-minute submaximal step exercise protocol (number of steps-p = 0.001) showed a statistical improvement in the severe clinical phenotype group after NIV. In addition, forced expiratory volume in the first one second to the forced vital capacity (p = 0.032) and the two-minute submaximal step exercise protocol (number of steps-p < 0.001) showed a statistical improvement in the mild clinical phenotype group after NIV. No changes were described for vital signs and the Borg scale. Conclusions: This study allowed us to identify that NIV is a tool that promotes better exercise capacity by increasing the number of steps achieved in both clinical phenotype groups and improving lung function observed in the spirometry markers.

The Critical Role of Sleep in Enhancing Pulmonary Rehabilitation Outcomes

Pulmonary rehabilitation is a comprehensive, interdisciplinary intervention that aims to enhance the physical and psychological well-being of individuals with chronic respiratory diseases. This approach entails the implementation of tailored therapies, including exercise training, education, and behavioral modification. Sleep plays a crucial role in numerous physiological processes, including the regulation of inflammation and tissue repair, both of which are fundamental to the efficacy of rehabilitation. A paucity of optimal sleep health has been associated with deleterious effects on pivotal factors that are indispensable for favorable outcomes in pulmonary rehabilitation, including mental and physical health and immune function. This, in turn, may increase susceptibility to impaired pulmonary function. The integration of pulmonary rehabilitation protocols with healthy sleep practices is expected to yield significant improvements in lung function and overall health, which will, in turn, promote long-term adherence to rehabilitative behaviors. This study aims to examine the relationship between sleep health and pulmonary rehabilitation outcomes.

Clinical analysis of the correlation between nutritional risk screening and prognosis of patients with chronic obstructive pulmonary disease

Objective

To explore the clinical correlation between nutritional risk screening and prognosis of patients with chronic obstructive pulmonary disease (COPD).

Method

Clinical data of 80 patients with COPD admitted to Beijing Hospital of integrated Traditional Chinese and Western Medicine between August 2020 and August 2023 were retrospectively analyzed. Patients were divided into the Mortality group (n=17) and the survival group (n=63) according to the three years follow-up outcomes. The related data were compared between the two groups, the prognostic factors were analyzed, and the correlation between nutritional risk and prognostic risk factors was explored. The value of nutritional risk in prognosis prediction was analyzed by ROC curve.

Result

Binary logistic regression analysis showed that complications (>2), NRS2002 score (nutritional risk), albumin (ALB), number of acute exacerbations of COPD (AECOPD) (≥2), pulmonary dysfunction (moderate to severe), and ventilator-associated pneumonia (VAP) after admission were prognostic risk factors (P<0.05). Complications, number of AECOPD, pulmonary dysfunction, and ALB were correlated with nutritional status (P<0.05). ROC curve analysis found that the AUC of NRS2002 score in prognosis prediction was 0.679(95%CI, 0.549-0.810), with a sensitivity of 88.2%, and a specificity of 47.6%, indicating the predictive value of this variable.

Conclusion

Complications (>2), NRS2002 score (nutritional risk), ALB, number of AECOPD (≥2), pulmonary dysfunction (moderate to severe), and VAP after admission are prognostic risk factors. Nutritional status may be closely related to prognostic risk factors and might be used as a predictor for prognosis.

Rehabilitation interventions and outcomes for post-COVID condition: a scoping review

Objective

Several rehabilitation interventions have been proposed to support people with post-COVID-19 condition (PCC). However, the full spectrum of these interventions remains unclear, partly due to the complexity of PCC, which encompasses a broad range of symptoms affecting multiple organ systems and health domains. This scoping review aimed to identify the available rehabilitation interventions for PCC and the outcome measures used to evaluate them, to facilitate the development of multifaceted interventions and improve patient care.

Methods

Following the Joanna Briggs Institute Framework, we searched CINAHL, EMBASE, MEDLINE, PsychINFO, CENTRAL and Scopus databases from inception to 22 January 2024 for experimental and observational studies investigating rehabilitation interventions for adults with PCC. Interventions and their corresponding outcome measures were synthesised based on targeted outcomes aligned with the most common manifestations of PCC. The quality of intervention reporting was assessed using the Template for Intervention Description and Replication (TIDieR) checklist.

Results

We identified 74 studies; 28 randomised trials (37.8%) and 46 observational and quasi-experimental designs (62.2%). Most interventions consisted of different combinations of education, exercises and therapies to manage dyspnoea, fatigue and psychological symptoms, such as anxiety and depression. Few studies addressed postexertional malaise, cognitive function, memory, balance and coordination. At least half of the included studies required a confirmed SARS-CoV-2 infection for participant inclusion. Reporting on adherence rates was limited, and 65% of the studies did not report adverse events.

Conclusion

There is a need for more comprehensive and inclusive approaches that address the full spectrum of PCC symptomatology to improve patient care and enhance the reproducibility of future studies.

Efficacy of Telerehabilitation Protocols for Improving Functionality in Post-COVID-19 Patients

BACKGROUND AND AIMS

Telerehabilitation is essential for the recovery of post-COVID-19 patients, improving exercise tolerance, dyspnea, functional capacity, and daily activity performance. This study aimed to describe telerehabilitation protocols specifically designed for individuals with post-COVID-19 sequelae.

MATERIALS AND METHODS

A systematic review was conducted with registration number CRD42023423678, based on searches developed in the following databases: ScienceDirect, Scopus, Dimensions.ai and PubMed, using keywords such as "telerehabilitation" and "COVID-19". The final search date was July 2024. The selection of studies involved an initial calibration process, followed by independent filtering by the researchers. The selection criteria were applied prior to critical appraisal, data extraction, and the risk of bias assessment.

RESULTS

After reviewing 405 full-text papers, 14 articles were included that focused on telerehabilitation interventions for post-COVID-19 patients. These interventions were designed for remote delivery and included exercise protocols, vital sign monitoring, and virtual supervision by physical therapists. The studies reported improvements in physical function, muscle performance, lung capacity, and psychological outcomes. Significant gains were observed in strength, mobility, and functional capacity, as well as reductions in dyspnea, fatigue, and improvements in quality of life, particularly in social domains. Intervention protocols included aerobic, strength, and respiratory exercises, monitored using tools such as heart rate monitors and smartphones.

CONCLUSIONS

Telerehabilitation positively impacts lung volumes, pulmonary capacities, dyspnea reduction, functionality, muscle performance, and independence in post-COVID-19 patients.

Impact of Respiratory Support During Hospitalization on Functional Outcomes in Long COVID: A Post-Hoc Analysis of a Prospective Cohort Study

Post-acute COVID-19 syndrome (PACS) is characterized by the persistence of one or more symptoms after the acute phase, leading to physical disabilities. This study aims to investigate whether the functional capacity and respiratory function 120 days post-COVID-19 differed according to the level of respiratory support needed during hospitalization in acute COVID-19 in the pre-vaccine rollout period. We followed up with 118 COVID-19 hospitalized patients in the acute phase until 120 days post-acute disease, with patients split into a Non-Invasive Oxygen Therapy Group (OTG, n = 72), Invasive Mechanical Ventilation Group (IMV, n = 12), and Room Air Group (RAG, n = 34), assessing the body composition, respiratory muscle strength, pulmonary function, functional capacity, and muscle strength at the follow-up visit. In total, 54 individuals (45.8%) were female, with a median age of 48 years old (IQR: 41-58). We found that the group with IMV was older (p < 0.001), had more admissions to the ICU (p < 0.001), and had longer hospital stays (p < 0.001). There were no statistically significant differences between groups (OTG, IMV, and RAG) for the spirometry function (p = 0.31), DASI score (p = 0.77), manovacuometry (MIP p = 0.74; MEP p = 0.23), 6MWT (p = 0.43), and handgrip (p = 0.19) outcomes. At D120, the IMV group had an important loss of body muscle mass (BMM) and a higher BMM than RAG (p = 0.02). Reduction in MIP (p = 0.01) and MEP (p = 0.02) in the IMV group and OTG group when compared to the RAG was also observed. Functional outcomes at 120 days from COVID-19 hospitalization were not found to be associated with the levels of oxygen supplementation during acute disease in this group of participants.

Effectiveness of Combined Pulmonary Rehabilitation and Progressive Muscle Relaxation in Treating Long-Term COVID-19 Symptoms: A Randomized Controlled Trial

Background: The aim of this study was to investigate the effects of pulmonary rehabilitation (PR) and additional progressive muscle relaxation (PMR) techniques in patients with long-term COVID-19 symptoms. Methods: We included 61 patients with long COVID-19 symptoms and randomly assigned them to two groups: PR only (group 1 with 30 subjects) and PR with PMR (group 2 with 31 subjects). The PR program consisted of gradual aerobic conditioning, strength training, and breathing exercises. Group 2 received additional 20 min daily sessions of progressive muscle relaxation techniques. Results: Following a 21-day intervention, it was observed that both groups had noteworthy improvements in lung function, exercise capacity, and sleep quality with statistical significance (p < 0.0001). Group 2 showed significant improvements in overall health (as measured by the General Health Questionnaire-12), patient health (as assessed by the Patient Health Questionnaire-9), general anxiety levels (as indicated by the Generalized Anxiety Disorders Scale-7), and sleep quality (as measured by the Pittsburgh Sleep Quality Index), with statistical significance (p < 0.0001), compared to group 1. Moreover, the statistical analysis demonstrated no significant difference in exercise capacity improvement between group 1 and group 2, as indicated by a p-value of 0.1711. Conclusions: The addition of progressive muscle relaxation to pulmonary rehabilitation significantly enhances mental health outcomes, particularly in reducing anxiety and improving sleep quality, for patients with long-term COVID-19 symptoms. These findings suggest that incorporating PMR into PR programs offers a valuable non-pharmacological approach to improving overall patient well-being during long-term COVID-19 recovery.

Does multifactorial inspiratory muscle training improve postural stability and quality of life of patients with diabetes in Pakistan? A randomised controlled trial

OBJECTIVE

To determine the effects of multifactorial inspiratory muscle training (IMT) combined with Otago Exercise Programme (OEP) on balance and quality of life (QoL) in patients with diabetes.

METHODS

Pretest-post-test randomised controlled trial.

SETTING

Rehabilitation Department of Pakistan Railway General Hospital.

PARTICIPANTS

70 patients with diabetes were randomly assigned to experimental or placebo groups, out of which 59 patients completed the intervention.

INTERVENTION

Patients in the experimental group performed OEP+IMT (at 50% of baseline maximum inspiratory pressure (MIP)) whereas the placebo group performed OEP+sham IMT (at 15% of MIP). Both groups exercised for 12 consecutive weeks.

OUTCOME MEASURES

Outcome measures included nine variables: the Berg Balance Scale (BBS), the Biodex Postural Stability System (including postural stability test (Overall Stability Index, Anterior-Posterior Index and Mediolateral Index), fall risk test (FRT), Limits of Stability (LOS) test (time to complete test and direction control), Clinical Test of Sensory Interaction and Balance (CTSIB)) and the Audit of Diabetes Dependent Quality of Life questionnaire.

RESULTS

Out of 59 patients who completed treatment, 37.1% were men and 62.9% were women with a mean age of 58.37±5.91 years. Results show significant interaction effects on BBS scores with the mean score improving from 41.87±2.61 to 49.16±2.50 in IMT versus sham IMT group with scores improving from 41.58±2.51 to 45.74±2.30. The IMT group significantly improved in dynamic balance tested through BBS (p=0.003), anticipatory balance through LOS test (p=0.003), reactive balance tested through FRT (p=0.04), direction control (p=0.03) and sensory integration through CTSIB test (p=0.04) when compared with the sham IMT group. While no significant changes (p>0.05) between groups were observed in QoL and static balance; significant changes (p<0.05) within group were observed in both groups in QoL and static balance.

CONCLUSION

Additional research is necessary to understand the association between inspiratory muscle strength and balance, however, we demonstrated that a multifactorial IMT intervention should be used with patients with diabetes to improve balance, postural control and reduce fall risks.

Physical therapy management of an individual with post-COVID fatigue considering emotional health in an outpatient setting: A case report

PURPOSE

The purpose of this case report is to provide a plan of care with an emphasis on patient education and consideration of emotional health for a patient with post-COVID fatigue in an outpatient setting.

CASE DESCRIPTION

A 50-year-old woman, ten-weeks post-COVID syndrome, participated in an examination that revealed deficits in exercise capacity, strength, breathing pattern, mild depression, emotional breakdown, and mild anxiety accompanied by "brain fog" with activity. Her primary complaint was fatigue with ordinary activities around her home that impeded her from returning to work. On examination, scores included six-minute walk test distance (6MWD): 79.5 m, UCSD Shortness of Breath Questionnaire (SOBQ): 72/120, and Patient Health Questionnaire (PHQ-9): 6/27. The patient participated in 20 biweekly sessions with a focus on patient education, supporting emotional health, aerobic training, strengthening exercises, breathing exercises, and home exercise program.

OUTCOMES

At discharge, the patient's exercise capacity, muscle strength, dyspnea, and depression improved, beyond the MCID/MID values, 6MWD: 335 m, SOBQ: 34/120; and PHQ-9 :1/27. The patient had no anxiety with activity and reported confidence to resume activities, allowing her to return to work safely.

CONCLUSION

Following an intervention that addressed emotional needs with physical symptoms, our patient with post-COVID fatigue showed substantial improvements in exercise capacity, muscle strength, dyspnea, and depression. This highlights the consideration of psychosocial well-being in our plan of care for this population.

The Effects of a Pulmonary Rehabilitation Programme on Functional Capacity and Strength of Respiratory Muscles in Patients with Post-COVID Syndrome

AIM

The aim of this study was to estimate the effects of a pulmonary rehabilitation programme (PR) on the functional capacity and respiratory muscle strength of patients with post-COVID syndrome.

METHODS

A cross-sectional study was conducted using hospital data on patients who participated in a pulmonary rehabilitation programme at the Clinic for Lung Diseases, University Hospital Centre Zagreb, Croatia, between January 2021 and December 2022. Data on the spirometry, respiratory muscle strength, and functional exercise capacity of patients were collected at baseline and three weeks after the start of rehabilitation. The study included 80 patients (43 females, 37 males) with a mean age of 51±10 years.

RESULTS

A significant increase in respiratory muscle strength (P<0.001) was observed after pulmonary rehabilitation, with effect sizes ranging from small to large (Cohen's d from 0.39 to 1.07), whereas the effect for PImax expressed as a percentage was large (Cohen's d=0.99). In addition, the pulmonary rehabilitation programme significantly improved the parameters of the six-minute walk test in patients, and the parameters of lung function, FVC, FEV1, and DLCO also improved significantly after PR (P<0.05).

CONCLUSION

The results showed that the pulmonary rehabilitation programme has clinically significant effects on functional capacity and respiratory muscle strength in patients with post-COVID syndrome.

Effects of respiratory muscular training in post-covid-19 patients: a systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Post-Covid-19 syndrome is defined as non-self-sustaining signs and/or symptoms lasting more than 12 weeks, occurring during or after a Covid-19 infection. The primary outcome was the analysis of the respiratory muscle training (RMT) result in respiratory muscle strength, (maximum inspiratory pressure (MIP) e maximum expiratory pressure (MEP)); and the secondary results were the analysis of lung function, dyspnea, quality of life (QoL), fatigue and functional performance.

METHODS

The PICO description for this research was: P: patients diagnosed with post-Covid-19; I: RMT; C: Sham or simulated inspiratory or expiratory muscle training and usual care; O: MIP, MEP, Lung Function, level of dyspnea, QoL and functional performance. On January 15, 2024, the following databases were consulted: PubMed, Lilacs, Cochrane Library, PEDro and EMBASE. Randomized clinical trials were included without restrictions on year of publication or language. The data selection and extraction steps were carried out by two independent reviewers.

RESULTS

The search in the databases resulted in a total of 14,216 studies, and after the eligibility process, 7 studies were included with a sample of 527 patients. The MIP results suffered a statistically significant increase, that is, the RMT was favorable to improve the MIP (MD = 29.55cmH2O IC 95%: 7.56cmH2O to 51.54cmH2O, p = 0,00001). For the MEP outcome, the results were statistically significant in favor of RMT (MD = 10.93cmH2O CI 95%: 3.65cmH2O to 18.21cmH2O, p = 0.00001). We also noticed a significant improvement for the group that received the RMT in the distance covered in the 6-Minute Walk Test (6MWT) MD = 40.70 m CI 95%: 18.23 m to 65.17 m%, p = 0.01).

CONCLUSION

We noticed that RMT is being used in patients with respiratory diseases, including post-Covid-19. Our systematic review observed that this training provides an increase in inspiratory and expiratory muscle strength, a reduction in dyspnea levels, and an increase in the distance covered in the 6MWT and improved QoL in post-covid patients after intervention.

Pulmonary rehabilitation in follow-up and inpatient rehabilitation for Long COVID: twelve months of follow-up

BACKGROUND

Individuals with persistent impairments due to Coronavirus disease 2019 (COVID-19) can receive pulmonary rehabilitation in Germany. To date, there is no evidence of the medium- or long-term effects of pulmonary rehabilitation on Long COVID.

AIM

This study examined changes in health and occupational outcomes over time and described the therapeutic content of pulmonary rehabilitation and aftercare. This analysis also compared two rehabilitation groups after COVID-19 who had different levels of access to rehabilitation.

DESIGN

Longitudinal observational study with multicenter and prospective data collection.

SETTING

Pulmonary rehabilitation in four different rehabilitation facilities in Germany.

POPULATION

Individuals with a mild course of disease and long-lasting impairments (inpatient rehabilitation, IR) and patients with a severe course after hospitalization (follow-up rehabilitation, FuR). Participants had to be between 18 and 65 years of age.

METHODS

Written questionnaires were administered at the beginning and end of rehabilitation, as well as six and twelve months after rehabilitation. Health-related quality of life (HrQoL), fatigue, participation restrictions, COVID-19 symptoms, mental and physical health were assessed, as well as occupational outcomes and questions about rehabilitation and aftercare.

RESULTS

IR patients were predominantly female (68.0%) and 52 years of age on average, while 66.1% of Long COVID rehabilitees in FuR were male and three years older. Over the course of rehabilitation, most COVID-19 symptoms decreased with statistical significance. The subjective health scales showed improvements with medium to large effect sizes (ES) over time in IR (P<0.01; ES between 0.55 (cognitive fatigue) and 1.40 (physical fatigue)) and small to large effects in FuR (P<0.01; ES between 0.45 (anxiety) and 1.32 (physical fatigue)). One year after rehabilitation, most effects remained at a moderate level. After twelve months, an increase in neurocognitive symptoms was observed in FuR patients. More than 80% of employed people returned to work one year after rehabilitation, although FuR patients returned to work a median of four weeks later (P<0.01).

CONCLUSIONS

The comparative analysis showed that rehabilitees in different forms of rehabilitation attended rehabilitation with different impairments and rehabilitation goals, which are partly considered in treatment and aftercare.

CLINICAL REHABILITATION IMPACT

To provide needs-based rehabilitation to different rehabilitation groups with Long COVID, knowledge of their health histories and preferences is necessary.

Association of pulmonary function test abnormalities and quality-of-life measures after COVID-19 infection

BACKGROUND

Long-COVID is a multisystem disease that can lead to significant impairments in health-related quality of life (HRQoL). Following COVID-19 infection, abnormalities on pulmonary function tests (PFT) are common. The primary aim of this study is to evaluate for any correlation between PFT abnormalities and impairment in HRQoL scores following COVID-19 infection.

METHODS

This is an analysis of a prospective cohort of patients in Louisville, KY who were infected with COVID-19. Data collected included demographics, past medical history, laboratory tests, PFTs, and several HRQoL questionnaires such as the EuroQol 5 Dimension HRQoL questionnaire (EQ-5D-5 L), Generalized Anxiety Disorder 7 (GAD-7), Patient Health Questionnaire (PHQ-9), and Posttraumatic stress disorder checklist for DSM-5 (PCL-5). Descriptive statistics were performed, comparing PFTs (normal vs abnormal) and time since COVID-19 infection (3- vs 6- vs ≥ 12 months).

RESULTS

There were no significant differences in FEV1, FVC, or the percentage of patients with abnormal PFTs over time after COVID-19 infection. Following COVID-19, patients with normal PFTs had worse impairment in mobility HRQoL scores and change in GAD-7 scores over time. There were no differences over time in any of the HRQoL scores among patients with abnormal PFTs.

CONCLUSIONS

Among patients with an abnormal PFT, there was no temporal association with HRQoL scores as measured by EQ-5D-5 L, GAD-7, PHQ-9, and PCL-5. Among patients with a normal PFT, mobility impairment and anxiety may be associated with COVID-19 infection. Following COVID-19 infection, impairment in HRQoL scores is not completely explained by the presence of abnormalities on spirometry.

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.

Quality of Life, Family Support, Spirometry, and 6-Minute Walking Distance Differences between COVID-19 and Non-COVID-19 Intensive Care Unit Patients in One Year Following Hospital Discharge

BACKGROUND

Critically ill patients after Intensive Care Unit (ICU) discharge may present disability in their cognitive and physical functions.

OBJECTIVES

To investigate the quality of life (QoL) of both COVID-19 and non-COVID-19 patients following ICU discharge, lung function, and physical performance of participants.

METHODS

This study was prospective and conducted between 2020 and 2021 in the "X" hospital. If patients were Mechanically-Ventilated (MV) > 48 h, they were included.

RESULTS

Fifty COVID-19 and seventy-two non-COVID-19 participants were included in this study. The mean (SD) of the total SF-36 scores at COVID-19 patients at hospital discharge and 3 and 12 months were 46.5 (14.5), 68.6 (17.8), and 82.3 (8.9) (p < 0.05), while non-COVID-19 participants were 48.5 (12.1), 72.2 (9.9), and 82.7 (5.4) (p < 0.05). The forced expiratory volume in one second (FEV1) and 6-minute walking distance (6MWD) were assessed at 3 and 12 months and significantly improved over 12 months.

CONCLUSION

The QoL of COVID-19 patients improved significantly over time as FEV1 and 6MWD.

Supervised Telerehabilitation and Home-Based Respiratory Muscle Training for Post-COVID-19 Condition Symptoms: A Nested Qualitative Study Exploring the Perspectives of Participants in a Randomized Controlled Trial

OBJECTIVE

The purpose of this study was to describe the experiences of individuals with post-coronavirus 19 (COVID-19) condition symptoms who underwent a supervised telerehabilitation and home-based respiratory muscle training (TSHB-RMT) program.

METHODS

A qualitative descriptive study was conducted. Participants were recruited using purposeful sampling. The inclusion criteria consisted of: patients aged over 18 years who presented persistent COVID-19 symptoms of fatigue and dyspnea for at least 3 months after the COVID-19 diagnosis. In total, 28 patients were included. In-depth interviews and researcher field notes were used to collect the data. A thematic analysis was performed.

RESULTS

Three themes reflect the patients' perspective on the TSHB-RMT before the program (reasons for participating), during the treatment program, and upon completion of the study. Among the reasons for participation, participants highlighted the absence of improvement and treatment, and feeling abandoned and forgotten by the health system. The treatment required discipline on behalf of the patients. Mondays and Tuesdays were the most difficult days for performing the therapy, and the physical therapist was perceived as a tool for adherence, change, and a source of validated information. The patients perceived positive effects quite soon; however, it was necessary to extend the follow-up after completing the program because they abandoned the program due to the lack of guidance for exercise supervision.

CONCLUSION

This study described relevant aspects that physical therapist professionals should consider when providing TSHB-RMT treatment.

IMPACT

TSHB-RMT requires discipline, perseverance, effort, and a commitment to the group. The physical therapist is perceived as the tool that facilitates adherence and participation. The effects are rapidly perceived, leading to improved self-confidence and autonomy; however, it is necessary to increase the follow-up time.

Practical Recommendations for Exercise Training in Patients with Long COVID with or without Post-exertional Malaise: A Best Practice Proposal

People with long COVID may suffer from a wide range of ongoing symptoms including fatigue, exertional dyspnea, reduced exercise performance, and others. In particular, impaired exercise performance is a condition that can be recovered in many people through an individualized physical exercise training program. However, clinical experience has shown that the presence of post-exertional malaise (PEM) is a significant barrier to physical exercise training in people with long COVID. Currently, there is no guideline or consensus available on how to apply exercise training in this cohort. Therefore, we conducted a literature review in the PubMed library using the following search terms: "COVID", "post-COVID", "long COVID" and "exercise" searching for studies from January 2020 to January 2024. Data from 46 trials were included. Exercise training regimes were very heterogeneous and none of these studies reported on the management of PEM in the context of an exercise training program. Based on the feedback from an additional survey that was answered by 14 international experts in the field of exercise training in long COVID, combined with the authors´ own extensive practical experience, a best practice proposal for exercise training recommendations has been developed. This proposal differentiates exercise procedures according to the presence of no, mild/moderate or severe PEM in people with long COVID. These recommendations may guide allied healthcare professionals worldwide in initiating and adjusting exercise training programs for people with long COVID, stratified according to the presence and severity of PEM.

The Significance of Selected Myokines in Predicting the Length of Rehabilitation of Patients after COVID-19 Infection

In the context of the global COVID-19 pandemic, understanding the intricate mechanisms of the body's response to infection and inflammation has become a priority for the medical and research communities. It has been proven that during COVID-19 infection, molecules are secreted-namely organokines, which may directly or indirectly play a role in the pathophysiology of COVID-19. The objective of this study was to scrutinize the potential correlation between the levels of selected myokines (myostatin, agrin, irisin, and myonectin) and the duration of rehabilitation in post-COVID-19 patients. Additionally, the study aimed to investigate whether there is a correlation between the levels of these myokines and the length of hospitalization during COVID-19 treatment. The study was conducted at the Rehabilitation Hospital in Szczecin (Poland). Patients in the study participated in a comprehensive rehabilitation program following COVID-19 treatment. In order to assess the effectiveness of rehabilitation, the following tests were performed: a 6 min walk test with an assessment of exercise tolerance (Borg scale), an assessment of dyspnea severity (mMRC scale), a spirometric assessment of respiratory function, a measurement of arm strength, and an assessment of fatigue using the Fatigue Assessment Scale (FAS). Myokine levels were measured using commercially available enzyme-linked immunosorbent assays (ELISA) according to the manufacturer's instructions. Statistical analysis was performed using Statistica 13.1 software. Lower concentrations of irisin and myonectin and higher concentrations of myostatin correlated with longer rehabilitation time. Baseline levels of specific myokines in post-COVID-19 patients could play a crucial role in anticipating the duration of rehabilitation. The duration of hospitalization for the infection may influence myokine levels in patients recovering from COVID-19.

Effects of a cardiopulmonary rehabilitation protocol on functional capacity, dyspnea, fatigue, and body composition in individuals with post-COVID-19 syndrome: A randomized controlled trial

BACKGROUND AND OBJECTIVE

Reduced functional capacity, dyspnea, fatigue, and changes in body composition are common in patients with post-COVID-19 syndrome (PCS), and cardiopulmonary rehabilitation may improve these parameters. Thus, the present study verified the effects of cardiopulmonary rehabilitation (respiratory, aerobic, and resistance muscle training) on submaximal exercise tolerance, dyspnea, fatigue, and body composition.

METHODS

This controlled and randomized clinical trial applied a six-week outpatient intervention protocol in individuals over 18 years old (n = 33) with a diagnosis of COVID-19 confirmed by polymerase chain reaction. These individuals were allocated to cardiopulmonary rehabilitation (n = 17) or control groups (i.e., educational lectures; n = 16). The cardiopulmonary rehabilitation group performed respiratory, aerobic, and resistance muscle training. Submaximal exercise tolerance, dyspnea, fatigue, and body composition were assessed before and after the protocol.

RESULTS

After 6 weeks, the cardiopulmonary rehabilitation group increased the tolerance to submaximal exercise, with a difference of 100.46 m (95% confidence interval [CI]: 7.40-193 m) in the distance walked on the six-minute walk test, reduced dyspnea (-1.45, 95% CI: -1.98--0.92) in the modified Medical Research Council, and increased 0.63 kg (95% CI: 0.09-1.18 kg) of muscle mass in the upper limbs compared with the control group.

CONCLUSION

The six-week cardiopulmonary rehabilitation protocol improved functional capacity, reduced dyspnea, and increased muscle mass in the upper limbs in individuals with PCS. Thus, these results supported the protocol use in this population and encourage further studies to assess its effectiveness in a large sample.

Effects of Pulmonary Rehabilitation on Respiratory Function and Thickness of the Diaphragm in Patients with Post-COVID-19 Syndrome: A Randomized Clinical Trial

BACKGROUND

Rehabilitation is an effective method for improving the overall health of patients who have experienced the long-term effects of COVID-19.

METHODS

The double-blind, randomized prospective study assessed the effectiveness of a 6-week rehabilitation program among post-COVID-19 patients. A total of 59 patients under treatment following COVID-19 were randomly divided into two groups. Both groups completed the same six-week comprehensive exercise training program supported by a respiratory muscle trainer (Threshold IMT) during out-patient sessions. The control group performed placebo IMT. Respiratory muscle strength, chest wall expansion, spirometry, and diaphragm ultrasonography measurements were taken before and after the six weeks.

RESULTS

The applied rehabilitation program improved respiratory muscle strength in both the study and control groups (p < 0.001). There was a significant chest circumference increase in the study group (p < 0.001). Spirometric parameters improved in both groups, with the study group showing a greater improvement: 8.02% in FEV1 (p < 0.001), 13.24% in FVC EX (p < 0.001) and 9.67% in PEF (p < 0.001). Rehabilitation also increased diaphragm thickness during maximum inhalation in both groups.

CONCLUSIONS

Based on the study findings, the specialized outpatient rehabilitation program developed for post-COVID-19 patients has proven to be effective and safe.

The effects of inspiratory muscle training on biomarkers of muscle damage in recovered COVID-19 patients after weaning from mechanical ventilation

Background: COVID-19 patients experience respiratory muscle damage, leading to reduced respiratory function and functional capacity often requiring mechanical ventilation which further increases susceptibility to muscle weakness. Inspiratory muscle training (IMT) may help mitigate this damage and improve respiratory function and functional capacity. Methods: We studied the effects of IMT on muscle damage biomarkers, respiratory function, and functional capacity in COVID-19 recovered young adults, successfully weaned from mechanical ventilation. Participants were randomly allocated to either an IMT (n = 11) or control (CON; n = 11) intervention for 4 weeks. The IMT group performed 30 dynamic inspiratory efforts twice daily, at 50% of their maximal inspiratory mouth pressure (PMmax) while the CON group performed 60 inspiratory efforts at 10% of pMmax daily. Serum was collected at baseline, week two, and week four to measure creatine kinase muscle-type (CKM), fast skeletal troponin-I (sTnI) and slow sTnI. Results: Time × group interaction effects were observed for CKM and slow sTnI, but not for fast sTnI. Both were lower at two and 4 weeks for the IMT compared to the CON group, respectively. Time × group interaction effects were observed for forced expiratory volume in 1s, forced vital capacity, PMmax and right- and left-hand grip strength. These were higher for the IMT compared to the CON group. Conclusion: Four weeks of IMT decreased muscle damage biomarkers and increased respiratory function and grip strength in recovered COVID-19 patients after weaning from mechanical ventilation.

Prediction models for physical function in COVID-19 survivors

BACKGROUND

The burden of caring for patients who have survived COVID-19 will be enormous in the coming years, especially with respect to physical function. Physical function has been routinely assessed using the Post-COVID-19 Functional Status (PCFS) scale.

AIM

This study built prediction models for the PCFS scale using sociodemographic data, clinical findings, lung function, and muscle strength.

METHOD

Two hundred and one patients with post-COVID-19 syndrome (PCS) completed the PCFS scale to assess physical function. Their levels of general fatigue were also assessed using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale, handgrip strength (HGS), and spirometry.

RESULTS

The number of participants who scored 0 (none), 1 (negligible), 2 (slight), 3 (moderate), and 4 (severe) on the PCFS scale was 25 (12%), 40 (20%), 39 (19%), 49 (24%), and 48 (24%), respectively. The PCFS scale was significantly correlated with the following variables: FACIT-F score (r = -0.424, P < 0.001), HGS (r = -0.339, P < 0.001), previous hospitalization (r = 0.226, P = 0.001), body mass index (r = 0.163, P = 0.021), and sex (r = -0.153, P = 0.030). The regression model with the highest coefficient of regression (R = 0.559) included the following variables: age, sex, body mass index, FACIT-F, HGS, and previous hospitalization.

CONCLUSIONS

Worse general fatigue and HGS are associated with more severe physical function impairments in PCS patients. Furthermore, a history of prior hospitalization results in worse physical function. Thus, prediction models for the PCFS scale that incorporate objective measures enable a better assessment of the physical function of these patients, thus helping in the selection of candidates for a program of physical reconditioning.

Respiratory Muscle Strength Training in Patients Post-COVID-19: A Systematic Review

Estimates of 10-49% of patients may experience ongoing symptoms after COVID-19, including dyspnea. Respiratory muscle strength training has been used to reduce dyspnea in other respiratory diseases, thus, it may be a viable option for individuals with post-COVID-19 symptoms. The objective of this review was to evaluate the evidence for the effectiveness of respiratory muscle strength training for individuals with post-COVID-19 dyspnea. A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. CINAHL, Web of Science, PubMed, EMBASE, Google Scholar, and Scopus databases were searched from 2020-2023. Eleven articles met the inclusion criteria. Pulmonary measures were improved in all but one study, and dyspnea, physical capacity and quality of life measures achieved statistical significance. Outcomes improved following respiratory muscle strength training as a standalone intervention, or with aerobic and peripheral muscle strength training.

Enhancing exercise intervention for patients with post-acute COVID-19 syndrome using mobile health technology: The COVIDReApp randomised controlled trial protocol

Objectives

To analyse the effectiveness of a physical exercise programme guided by a mobile health technology system (COVIDReApp) for patients with post-acute COVID-19 syndrome. This syndrome is a multisystem disease that occurs in people with a history of COVID-19 between 1 and 3 months after the onset of the disease. This study will assess the impact of the intervention on fatigue, post-exertional dyspnoea, quality of life, pain severity, physical fitness, anxiety, depression and cognitive function. We also aim to analyse whether there are associations between the variables studied and the evolution of these associations during follow-up.

Design

A single-blind randomised controlled trial.

Methods

One hundred patients diagnosed with post-acute COVID-19 will be enrolled and randomly assigned to two groups. The experimental group will perform the intervention through a physical exercise programme guided by the COVIDReApp system, whereas the control group will perform the programme in paper format. Study outcomes will be collected at baseline and at 4, 12 and 24 weeks. Student's t-tests or Mann-Whitney U-tests will be used to analyse differences between groups, mixed ANOVA for differences over time and longitudinal structural equations for associations between variables at follow-up.

Discussion

This study is based on current evidence regarding exercise prescription recommendations for patients with post-acute COVID-19 syndrome. Our intervention is supported by a solid theoretical framework; however, challenges include tailoring the physical exercise programme to everyone's predominant symptoms and ensuring adherence to the programme.

Trial registration number

Effectiveness of a respiratory rehabilitation program including an inspiration training device versus traditional respiratory rehabilitation: a randomized controlled trial

Background

In the context of COVID-19, respiratory training is vital for the care and recuperation of individuals. Both exercise-based and instrumental respiratory training have been employed as interventions to enhance respiratory function, providing relief from symptoms in those impacted by the virus. The aim of this study was to evaluate the efficacy of two different respiratory rehabilitation programs.

Methods

A total of 200 participants affected with COVID-19 respiratory sequels were recruited, with a block randomization regarding sex to ensure equal and appropriate applicability of the results. An experimental controlled and randomized study was conducted, with participants engaging in a 31 days respiratory rehabilitation program, (a) experimental group, inspiratory training device combined with aerobic exercise and (b) traditional respiratory exercises combined with aerobic exercise.

Results

Both groups improved in cardiorespiratory parameters, with a decrease in systolic and diastolic pressure, dyspnea and lower limbs fatigue, and increased oxygen saturation, 6 min walking distance, diaphragmatic thickness, forced vital capacity, forced expiratory volume during the first second, peak expiratory flow rate, forced inspiratory vital capacity and maximal inspiratory pressure. Comparison between groups showed statistically significant differences in all variables except for oxygen saturation, 6 min walking distance and diaphragmatic thickness. The results of this study support the use of specific inspiration training devices for respiratory rehabilitation in COVID-19 sequels.

The vital role of exercise and nutrition in COVID-19 rehabilitation: synergizing strength

Since the outset of the COVID-19 pandemic, the global healthcare community has faced the challenge of understanding and addressing the ongoing and multi-faceted SARS-CoV-2 infection outcomes. As millions of individuals worldwide continue to navigate the complexities of post-hospitalization recovery, reinfection rates, and the increasing prevalence of Long-COVID symptoms, comprehensive COVID-19 rehabilitation strategies are greatly needed. Previous studies have highlighted the potential synergy between exercise and nutrition, suggesting that their integration into patient rehabilitation programs may yield improved clinical outcomes for survivors of COVID-19. Our group aimed to consolidate existing knowledge following the implementation of patient, intervention, comparison, and outcome (PICO) search strategies on the distinct and combined impacts of exercise and nutrition interventions in facilitating the recovery of COVID-19 patients following hospitalization, with a specific focus on their implications for both public health and clinical practice. The incorporation of targeted nutritional strategies alongside exercise-based programs may expedite patient recovery, ultimately promoting independence in performing activities of daily living (ADLs). Nonetheless, an imperative for expanded scientific inquiry remains, particularly in the realm of combined interventions. This mini-review underscores the compelling prospects offered by an amalgamated approach, advocating for the seamless integration of exercise and nutrition as integral components of post-hospitalization COVID-19 rehabilitation. The pursuit of a comprehensive understanding of the synergistic effects and effectiveness of exercise and nutrition stands as a crucial objective in advancing patient care and refining recovery strategies in the wake of this enduring global health crisis.

The Impact of Comprehensive Rehabilitation on the Exercise Capacity of Patients after COVID-19

Coronavirus Disease 2019 (COVID-19) is a complex disease that affects multiple body systems, including the respiratory, cardiovascular, neurological, and muscular systems. It is estimated that approximately half of the patients after the treatment for COVID-19 experience persistent symptoms that lead to a decreased physical capacity. Scientific recommendations suggest that cardiovascular and respiratory rehabilitation programs should be implemented in patients who have completed treatment for COVID-19. Therefore, the objective of this study was to evaluate the impact of comprehensive rehabilitation on the exercise capacity of patients after COVID-19 treatment. The study included 146 patients after the treatment for COVID-19 who were eligible for therapeutic rehabilitation. The exercise capacity was assessed using the 6-minute walk test (6MWT). The results showed that patients who underwent rehabilitation had an average increase of 23.83% in their 6MWT score compared to the baseline. A comprehensive rehabilitation program including breathing exercises, aerobic training, and strength and endurance exercises is an effective intervention that can improve the physical capacity of patients after COVID-19 treatment.

Meta-analysis of the impact of physical activity on the recovery of physical function in COVID-19 patients

Background

The decrease in physical function resulting from COVID-19 infection exerts a substantial negative influence on the quality of life of individuals. Physical activity plays a crucial and irreplaceable role in hastening the elimination of adverse effects on the body caused by acute and chronic diseases. Nevertheless, there have been reports of unfavorable events following physical activity post-COVID-19 infection, sparking debate regarding the efficacy of physical activity as a rehabilitation method to enhance the physical function of COVID-19 patients.

Objective

The aim of this study is to investigate the impact of physical activity on promoting the restoration of physical function among individuals with COVID-19, and to offer guidance for the advancement and consideration of physical activity in the rehabilitation treatment of COVID-19 patients.

Methods

A search was conducted on the PubMed and Web of Science core collection databases, with the search period set from January 1, 2020, to February 6, 2023. The included literature was assessed for risk of bias and methodological quality according to the Cochrane Handbook for Systematic Reviews of Interventions, utilizing Review Manager 5.1 software. The outcome measures from the included studies were analyzed, and the quality of evidence for the outcome measures was graded using the GRADE classification criteria.

Results

The effect of physical activity intervention on improving the 6-Minute Walk Test score in COVID-19 patients was better than that of conventional treatment [WMD = 69.19(95%CI = 39.38, 98.99), I2 = 57%(p = 0.03)]. The effect of physical activity on improving the 30-Second Sit-to-Stand Test score was better than that of conventional treatment [WMD = 2.98(95%CI = 1.91, 4.04), I2 = 0%(p = 0.56)]. There was no significant difference between physical activity and conventional treatment in improving Grip strength in COVID-19 patients [WMD = 2.35(95%CI = -0.49, 5.20), I2 = 0%(p = 0.80)]. The effect of physical activity on improving the Timed Up and Go test score in COVID-19 patients was better than that of conventional treatment [WMD = -1.16(95%CI = -1.98, -0.34), I2 = 4%(p = 0.35)]. The effect of physical activity on improving Forced Vital Capacity in COVID-19 patients was better than that of conventional treatment [WMD = 0.14(95%CI = 0.08, 0.21), I2 = 0%(p = 0.45)]. The effect of physical activity on improving Forced Expiratory Volume in the first second in COVID-19 patients was better than that of conventional treatment [WMD = 0.08(95%CI = 0.02, 0.15), I2 = 52%(p = 0.10)].

Conclusions

Physical activity plays a crucial role in facilitating the recovery of exercise capacity and pulmonary function in COVID-19 patients, helping to expedite the restoration of overall physical health. It is crucial for COVID-19 patients to undergo an accurate assessment of their physical condition before engaging in any physical activity.

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

BACKGROUND

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.

METHODS

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).

RESULTS

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.

CONCLUSIONS

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.

Does Physical Activity Affect Clinical Symptoms and the Quality of Life of Mild-Infected Individuals with COVID-19 in China? A Cross-Sectional Study

BACKGROUND

Few studies have identified the links between physical activity (PA), clinical symptoms, and the quality of life (QoL) among mildly infected individuals with COVID-19. This cross-sectional study aims to evaluate how PA levels before infections affect the infectious symptoms and the QoL in mildly infected patients with COVID-19.

METHODS

An online questionnaire link including participants' sociodemographic and anthropometric characteristics, clinical symptoms during the COVID-19 infectious period, the QoL of the worst symptomatic day, and PA in the last seven days before COVID-19 infections was disclosed. Logistic regression and multiple linear regression analyses were applied to assess the relationships between PA levels in the last seven days before infections and COVID-19-related outcomes. The level of statistical significance was set at p < 0.05.

RESULTS

Compared to the low-PA-level group, the moderate-PA-level group presented a higher risk of headaches (OR = 1.34, 95% CI = 1.03 to 1.75, and p = 0.03) and the high-PA-level group presented a higher risk of muscle/body aches (OR = 1.42, 95% CI = 1.04 to 1.93, and p = 0.03). The adjusted linear regression analysis showed that no associations were found between PA levels in the last seven days before infections and the QoL index value on the worst symptomatic day (moderate-PA-level group: β = -0.04, and p = 0.08; high-PA-level group: β = -0.04, and p = 0.17). However, for the mobility and usual activities dimensions of EQ-5D-5L, the lower-PA-level group had a lower burden of QoL than the higher-PA-level group did on the worst-symptomatic day.

CONCLUSIONS

Among mildly infected patients with COVID-19, a higher PA level is associated with a higher risk of experiencing clinical symptoms and a lower QoL.

Effectiveness of exercise training on the dyspnoea of individuals with long COVID: A randomised controlled multicentre trial

BACKGROUND

COVID-19-related acute respiratory distress syndrome (CARDS) is a severe evolution of the Sars-Cov-2 infection and necessitates intensive care. COVID-19 may subsequently be associated with long COVID, whose symptoms can include persistent respiratory symptoms up to 1 year later. Rehabilitation is currently recommended by most guidelines for people with this condition.

OBJECTIVES

To evaluate the effects of exercise training rehabilitation (ETR) on dyspnoea and health-related quality of life measures in people with continuing respiratory discomfort following CARDS.

METHODS

In this multicentre, two-arm, parallel, open, assessor-blinded, randomised controlled trial, we enroled adults previously admitted with CARDS to 3 French intensive care units who had been discharged at least 3 months earlier and who presented with an mMRC dyspnoea scale score > 1. Participants received either ETR or standard physiotherapy (SP) for 90 days. The primary outcome was dyspnoea, as measured by the Multidimensional Dyspnoea Profile (MDP), at day 0 (inclusion) and after 90 days of physiotherapy. Secondary outcomes were the mMRC and 12-item Short-Form Survey scores.

RESULTS

Between August 7, 2020, and January 26, 2022, 487 participants with CARDS were screened for inclusion, of whom 60 were randomly assigned to receive either ETR (n = 27) or SP (n = 33). Mean MDP following ETR was 42% lower than after SP (26.15 vs. 44.76); a difference of -18.61 (95% CI -27.78 to -9.44; p<10-4).

CONCLUSION

People who were still suffering from breathlessness three months after being discharged from hospital with CARDS had significantly improved dyspnoea scores when treated with ETR therapy for 90 days unlike those who only received SP. Study registered 29/09/2020 on Clinicaltrials.gov (NCT04569266).

Effects of Comprehensive Rehabilitation on Pulmonary Function in Patients Recovering from COVID-19

The aim of this study is to evaluate the effect of inpatient rehabilitation on pulmonary function in patients recovering from COVID-19, a multifaceted disease caused by the SARS-CoV-2 virus. This aspect of recovery is crucial, as pneumonia associated with this disease can cause lung-function abnormalities with varying degrees of hypoxemia. This study involved 150 patients qualified for inpatient rehabilitation following SARS-CoV-2 infection. Functional assessment of the lungs was performed by spirometry. The mean age of patients was 64.66 (±11.93) years, and the mean body mass index (BMI) was 29.16 (±5.68). The tests showed a statistically significant improvement in spirometric parameters. The rehabilitation program based on aerobic, strength, and endurance exercises improved lung-function parameters in the long term. The improvement in spirometric parameters in patients after COVID-19 may be related to body mass index (BMI).

Post-COVID-19 Syndrome Comprehensive Assessment: From Clinical Diagnosis to Imaging and Biochemical-Guided Diagnosis and Management

The COVID-19 outbreak was first reported in 2019, causing massive morbidity and mortality. The majority of the COVID-19 patients survived and developed Post-COVID-19 Syndrome (PC19S) of varying severity. Currently, the diagnosis of PC19S is achieved through history and symptomatology that cannot be explained by an alternative diagnosis. However, the heavy reliance on subjective reporting is prone to reporting errors. Besides, there is no unified diagnostic assessment tool to classify the clinical severity of patients. This leads to significant difficulties when managing patients in terms of public resource utilization, clinical progression monitorization and rehabilitation plan formulation. This narrative review aims to review current evidence of diagnosis based on triple assessment: clinical symptomatology, biochemical analysis and imaging evidence. Further assessment tools can be developed based on triple assessment to monitor patient's clinical progression, prognosis and intervals of monitoring. It also highlights the high-risk features of patients for closer and earlier monitoring. Rehabilitation programs and related clinical trials are evaluated; however, most of them focus on cardiorespiratory fitness and psychiatric presentations such as anxiety and depression. Further research is required to establish an objective and comprehensive assessment tool to facilitate clinical management and rehabilitation plans.
