Effectiveness of respiratory rehabilitation in patients with COVID-19: A meta-analysis.

AIM: Examine effectiveness of respiratory rehabilitation and moderating factors on lung function and exercise capacity in post-COVID-19 patients. DESIGN: Meta-analysis. METHODS: R software 4.0.2 assessed the effectiveness of respiratory rehabilitation adopting the random-effects model and presenting standardised mean differences (SMDs). Heterogeneity was determined by Cochran's Q and I2 . The Cochrane Risk of Bias 2.0 and MINORS evaluated quality of the included studies. DATA SOURCES: A comprehensive search was undertaken in Cochrane, Embase, Ovid-MEDLINE, Scopus, NCBI SARS-CoV-2 Resources, ProQuest, Web of Science and CINAHL until March 2022. RESULTS: Of the 5703 identified studies, 12 articles with 596 post-COVID-19 patients were included. Eleven of our twelve studies had moderate to high quality and one study had high risk of bias assessed with MINORS and RoB 2 tool. Overall, respiratory rehabilitation was effective in improving forced expiratory volume in 1 s (1.14; 95%CI 0.39-1.18), forced vital capacity (0.98; 95%CI 0.39-1.56), total lung capacity (0.83; 95%CI 0.22-1.44), 6-minute walk distance (1.56; 95%CI 1.10-2.02) and quality of life (0.99; 95%CI 0.38-1.60). However, no significant differences were observed for ratio of the forced expiratory volume in 1 s to the forced vital capacity of the lungs, anxiety and depression. Respiratory rehabilitation for post-COVID-19 patients was effective in those without comorbidities, performed four types of exercise programs, frequency ≥3 times/week and rehabilitation time 6 weeks. CONCLUSIONS: Respiratory rehabilitation improved lung function, exercise capacity and quality of life in post-COVID-19 patients. The findings suggest rehabilitation programs for post-COVID-19 patients should use multiple respiratory exercise programs with frequency of ≥3 times per week for longer than 6 weeks. IMPACT: These findings will help improve the implementation of respiratory rehabilitation programs for post-COVID-19 patients. IMPLICATIONS FOR THE PROFESSION: Our findings can be used to develop patient-centred respiratory rehabilitation interventions by nurses and clinicians for post-COVID-19 patients. REPORTING METHOD: PRISMA guideline was followed. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Non-invasive brain stimulation for fatigue in post-acute sequelae of SARS-CoV-2 (PASC).

BACKGROUND: and purpose: Fatigue is among the most common persistent symptoms following post-acute sequelae of Sars-COV-2 infection (PASC). The current study investigated the potential therapeutic effects of High-Definition transcranial Direct Current Stimulation (HD-tDCS) associated with rehabilitation program for the management of PASC-related fatigue. METHODS: Seventy patients with PASC-related fatigue were randomized to receive 3 mA or sham HD-tDCS targeting the left primary motor cortex (M1) for 30 min paired with a rehabilitation program. Each patient underwent 10 sessions (2 sessions/week) over five weeks. Fatigue was measured as the primary outcome before and after the intervention using the Modified Fatigue Impact Scale (MFIS). Pain level, anxiety severity and quality of life were secondary outcomes assessed, respectively, through the McGill Questionnaire, Hamilton Anxiety Rating Scale (HAM-A) and WHOQOL. RESULTS: Active HD-tDCS resulted in significantly greater reduction in fatigue compared to sham HD-tDCS (mean group MFIS reduction of 22.11 points vs 10.34 points). Distinct effects of HD-tDCS were observed in fatigue domains with greater effect on cognitive (mean group difference 8.29 points; effect size 1.1; 95% CI 3.56-13.01; P < .0001) and psychosocial domains (mean group difference 2.37 points; effect size 1.2; 95% CI 1.34-3.40; P < .0001), with no significant difference between the groups in the physical subscale (mean group difference 0.71 points; effect size 0.1; 95% CI 4.47-5.90; P = .09). Compared to sham, the active HD-tDCS group also had a significant reduction in anxiety (mean group difference 4.88; effect size 0.9; 95% CI 1.93-7.84; P < .0001) and improvement in quality of life (mean group difference 14.80; effect size 0.7; 95% CI 7.87-21.73; P < .0001). There was no significant difference in pain (mean group difference -0.74; no effect size; 95% CI 3.66-5.14; P = .09). CONCLUSION: An intervention with M1 targeted HD-tDCS paired with a rehabilitation program was effective in reducing fatigue and anxiety, while improving quality of life in people with PASC.

Clinical Features and Paraclinical Findings in Patients with SARS CoV-2 Pneumonia and the Impact of Pulmonary Rehabilitation on the Instrumental Activities of Daily Living in POST-COVID-19 Patients.

The functional sequelae grouped under the name "long COVID" most often bring the patient in front of a team of specialists in pulmonary rehabilitation. The aim of this study was to evaluate clinical features and paraclinical findings in patients with SARS CoV-2 (Severe Acute Respiratory Syndrome-Corona Virus-2) pneumonia and to also evaluate the impact of rehabilitation in this category of patients. This study included 106 patients diagnosed with SARS CoV-2. The division of the patients into two groups was performed based on the presence of SAR-CoV-2 pneumonia. Clinical symptoms, biochemical parameters, and pulmonary functional and radiological examinations were recorded and analyzed. The Lawton Instrumental Activities of Daily Living (IADL) scale was applied to all patients. Patients in group I were included in the pulmonary rehabilitation program. Among demographic characteristics, age over 50 years (50.9%; p = 0.027) and the female sex (66%; p = 0.042) were risk factors for pneumonia in patients with SARS CoV-2. Over 90% of the 26 patients included in the rehabilitation program were less able to feed, bathe, dress, and walk. After 2 weeks, approximately 50% of patients were able to eat, wash, and dress. It is important to provide longer rehabilitation programs in cases of moderate, severe, and very severe COVID-19 patients, in order to significantly improve patients' participation in daily activities and their quality of life.

Eight Weeks of Pilates Training Improves Respiratory Measures in People With a History of COVID-19: A Preliminary Study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) can result in prolonged and severe damage to the lungs and quality of life (QoL). This study was designed to investigate the effects of 8-week Pilates and Aqua-Pilates training on pulmonary function and QoL in patients with COVID-19. HYPOTHESIS: Pilates and Aqua-Pilates training promotes similar changes on pulmonary function and QoL in people with a history of COVID-19. STUDY DESIGN: Randomized controlled trial. LEVEL OF EVIDENCE: Level 3. METHODS: A total of 45 participants (24 men and 21 women) with a history of COVID-19 were assigned randomly to 3 groups: Pilates training (standard Pilates), Aqua-Pilates training (Pilates in water), and Control. The training protocol was performed for 8 weeks (3 sessions per week). Forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and the ratio of FEV1 to the FVC (FEV1/FVC) indices were measured by a spirometer. The 26-item questionnaire World Health Organization Quality of Life (WHOQOL) BREF was used to assess QoL. Data were analyzed using paired-sample t test and analysis of covariance with an alpha level <0.05. RESULTS: The mean age of the participants was 49.9 ± 6.4 years. After 8 weeks of Pilates and Aqua-Pilates training, there were significant increases in FVC (21.4% for Pilates and 22.1% for Aqua-Pilates, P < 0.05), FEV1 (32.3% for Pilates and 34.7% for Aqua-Pilates, P < 0.05), and FEV1/FVC% (9% for Pilates and 10.3% for Aqua-Pilates, P < 0.05) for the experimental groups, but not for control. Changes for Pilates and Acqua-Pilates were significantly higher than for control. The QoL scores were significantly different within and between the experimental groups, with greater improvements in the Aqua Pilates group than in the Pilates group. CONCLUSION: An 8-week Pilates or Aqua-Pilates training can improve pulmonary function as much as 34%, depending on the parameter, and QoL in people with a history of COVID-19. Aqua-Pilates training appears to be preferable to standard Pilates. CLINICAL RELEVANCE: The findings provide important insights into how healthcare professionals can prescribe exercise for COVID-19 survivors.

Identifying Appropriate Delivery of and Referral to Pulmonary Rehabilitation in Uganda: A Survey Study of People Living with Chronic Respiratory Disease and Health Care Workers.

Introduction: Pulmonary rehabilitation (PR) is a low cost, high impact intervention that ameliorates the disability associated with chronic respiratory diseases (CRD). PR is becoming increasingly recognized in low resource settings where the burden of CRD is rapidly increasing. To aid the implementation of PR in Uganda, we conducted a study to assess the attitudes and opinions towards PR among patients with CRD in Uganda and explore barriers faced by health care workers (HCWs) in referring to PR. Methods: A cross-sectional study comprising two survey populations: people living with CRD and HCWs regarded as potential PR referrers and PR deliverers. This exploratory study sought initial opinions and thoughts regarding PR, as well as baseline knowledge and potential barriers faced in the referral process. Results: Overall, 30 HCWs (53% female, 43% doctors) and 51 adults with CRD (63% female) participated in the survey. Among those with CRD, the majority reported breathlessness as a major problem (86%) and breathlessness affected their ability to do paid and unpaid work (70%). Interest in PR was high amongst adults with CRD (92%) with preference for a hospital-based programme (67%) as opposed to community-based (16%) or home-based (17%). All HCWs considered PR important in lung disease management, but 77% do not refer patients due to a lack of information about PR. HCWs' free-text responses identified the need for training in PR, patient education and streamlining the referral process as key elements to develop successful PR referral services. Conclusion: To successfully set up a PR service for people with CRD in Uganda, there is a great need for appropriately tailored training and education of prospective referrers about CRD and PR programs. Educating patients about the benefits of PR as well as streamlining the referral process is critical in expanding PR services across Uganda to fulfill this unmet need.

Effects of short-term breathing exercises on respiratory recovery in patients with COVID-19: a quasi-experimental study.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a highly infectious respiratory tract disease. The most common clinical manifestation of severe COVID-19 is acute respiratory failure. Respiratory rehabilitation can be a crucial part of treatment, but data lack for patients with COVID-19. This study investigates the effects of short-term respiratory rehabilitation (i.e., breathing exercises) on respiratory recovery among non-ICU hospitalised patients with COVID-19. METHODS: This was a quasi-experimental, pre-and post-test study. The study recruited 173 patients hospitalised with moderate to severe COVID-19. All the patients received standardised care for COVID-19, and 94 patients in the intervention group also received the intervention of breathing exercises, which included breathing control, followed by diaphragmatic breathing, deep breathing, or thoracic expansion exercise, and huffing (forced expiratory technique) and coughing. Data on the mean values of peripheral oxygen saturation (SpO2), need for oxygen therapy (litre/min), respiratory rate (breaths/minute), and heart rate (beats/minute) and were collected at baseline, 4 days, and 7 days after the baseline assessment. Analysis of variance on repeated measures was applied to compare the mean value of outcome measures of all the time points. RESULTS: The mean (± SD) age of the intervention (69.6% men) and control group (62.1% men) were 50.1 (10.5) and 51.5 (10.4) years, respectively. At 4-day of follow-up, SpO2 (96.6% ± 1.9 vs. 90.7% ± 1.8, P < 0.001), need for oxygen therapy (0.8 ± 2.6 vs. 2.3 ± 2.9, P < 0.001), respiratory rate (20.5 ± 2.3 vs. 22.3 ± 2.5, P < 0.001), and heart rate (81.2 ± 9.5 vs. 89.2 ± 8.9, P < 0.001) improved in the intervention group compared to the control group. At 7-day follow-up, differences remained significant concerning the oxygen saturation and the need for oxygen therapy (P < 0.001) between the groups. CONCLUSIONS: Our results indicate that breathing exercise, even for a short period, effectively improves specific respiratory parameters in moderate to severe COVID-19 patients. As a non-invasive and cost-effective respiratory rehabilitation intervention, breathing exercise can be a valuable tool for a health care system overwhelmed by the COVID-19 pandemic. These results should be considered preliminary until they are replicated in larger samples in different settings.

Cardiopulmonary Rehabilitation in Long-COVID-19 Patients with Persistent Breathlessness and Fatigue: The COVID-Rehab Study.

(1) Background: Cardiopulmonary and brain functions are frequently impaired after COVID-19 infection. Exercise rehabilitation could have a major impact on the healing process of patients affected by long COVID-19. (2) Methods: The COVID-Rehab study will investigate the effectiveness of an eight-week cardiopulmonary rehabilitation program on cardiorespiratory fitness (V˙O2max) in long-COVID-19 individuals. Secondary objectives will include functional capacity, quality of life, perceived stress, sleep quality (questionnaires), respiratory capacity (spirometry test), coagulation, inflammatory and oxidative-stress profile (blood draw), cognition (neuropsychological tests), neurovascular coupling and pulsatility (fNIRS). The COVID-Rehab project was a randomised clinical trial with two intervention arms (1:1 ratio) that will be blindly evaluated. It will recruit a total of 40 individuals: (1) rehabilitation: centre-based exercise-training program (eight weeks, three times per week); (2) control: individuals will have to maintain their daily habits. (3) Conclusions: Currently, there are no specific rehabilitation guidelines for long-COVID-19 patients, but preliminary studies show encouraging results. Clinicaltrials.gov (NCT05035628).

REHABILITATION OF PATIENTS WITH COVID-19: THE VIEW OF AN INFECTIOUS DISEASE SPECIALIST AND A PULMONOLOGIST

The COVID-19 pandemic has been going on for more than a year and a half, and the number of confirmed cases of infection in the world has already exceeded 150 million people. The multisystemic nature of the lesions in COVID-19, as well as the Post-COVID-19 syndrome, has been proven, which requires a rethinking of the rehabilitation of such patients. This lecture discusses current approaches to medical rehabilitation in patients with COVID-19 from the view of an infectious disease specialist and a pulmonologist. Methods and exercises of respiratory rehabilitation, including early ones, are indicated in detail. The directions of pharmacological and dietary support of rehabilitation, as well as vaccination after COVID-19 in the aspect of rehabilitation are presented. The directions of studying the human respiratory microbiome in the context of rehabilitation after COVID-19 are proposed. © 2021,HIV Infection and Immunosuppressive Disorders. All Rights Reserved.

The Aftermath of the COVID-19 Crisis in Saudi Arabia: Respiratory Rehabilitation Recommendations by Physical Therapists.

Since late 2019, the number of COVID-19 patients has gradually increased in certain regions as consecutive waves of infections hit countries. Whenever this wave hits the corresponding areas, the entire healthcare system must respond quickly to curb the diseases, morbidities, and mortalities in intensive care settings. The healthcare team involved in COVID-19 patients' care must work tirelessly without having breaks. Our understanding of COVID-19 is limited as new challenges emerge with new COVID-19 variants appearing in different world regions. Though medical therapies are finding solutions to deal with the disease, there are few recommendations for respiratory rehabilitation therapies. A group of respiratory rehabilitation care professionals in Saudi Arabia and international experts have agreed with the World Health bodies such as the World Health Organization (WHO) on the treatment and rehabilitation of patients with COVID-19. Professionals participating in COVID-19 patient treatment, rehabilitation, and recovery formulated respiratory rehabilitation guidelines based on the DELPHI Method, combining scientific research and personal practical experience. As a result, it is envisaged that the number of individuals in the region suffering from respiratory ailments due to post-COVID-19 will decrease. This narrative review and clinical expertise guidelines may give physiotherapists acceptable and standard clinical guideline protocols for treating COVID-19 patients.

Respiratory rehabilitation for Covid-19 related persistent dyspnoea: A one-year experience.

BACKGROUND: Growing consideration is emerging regarding the burden of persisting sequelae after SARS-CoV-2 infection. Out-patients exhibiting long Covid may benefit from ambulatory rehabilitation which is, to date, poorly documented. METHODS: A longitudinal follow-up over a one-year period was conducted in two ambulatory rehabilitation structures in order to describe the characteristics of real-life patients referred with Covid-19 sequelae and their evolution over the course of rehabilitation. RESULTS: 39 consecutive patients were included from April 1st, 2020 to April 1st, 2021. Patients were middle-aged (48 ± 15yr), without comorbidities, and mostly mild to moderate SARS-CoV-2 infection (25(64%) not requiring hospitalisation). Rehabilitation referral was considered with a median delay of 73[34-178] days after disease onset. Most prevalent symptoms were dyspnoea (n = 35(90%)) and fatigue (n = 30(77%)). Hyperventilation syndrome was highly frequent (n = 12(34%)). 29(74%) patients presented with prolonged functional sequelae, which was associated with younger age (43 ± 14 vs. 50 ± 10yr; p = 0.002), greater prevalence of hyperventilation syndrome (n = 12(41%) vs. 0(0%); p = 0.255) and poorer quality of life (VQ-11; 31 ± 10 vs. 23 ± 9; p = 0.030). Over the course of rehabilitation, exertional dyspnoea, 6-min walking distance, 3-min sit-to-stand test, hyperventilation syndrome prevalence and quality of life significantly improved. CONCLUSION: Hyperventilation is frequent in long Covid and may explain persistent dyspnoea as well as altered quality of life. Our data support screening of hyperventilation syndrome and functional impairment in mild Covid-19 out-patients as both of these components may improve with ambulatory rehabilitation.

Respiratory Telerehabilitation of Boys and Young Men with Duchenne Muscular Dystrophy in the COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic forced reorganization of the multidisciplinary healthcare system for Duchenne muscular dystrophy. Digital solutions seem to be optimal for providing rehabilitation at this time. The aim of this study was to investigate whether it is possible to conduct respiratory physical therapy with the use of telerehabilitation in Duchenne muscular dystrophy. METHODS: The study was conducted during an online conference for families with DMD. During the physical therapy panel we showed the video with the instructions of respiratory exercises. All participants (n = 152) were asked to fill in the online survey evaluating the quality, acceptance, and understanding of the instructions. RESULTS: The survey was filled in by 45 (29.6%) participants. The mean rating of satisfaction was 4.70/5, and for intelligibility was 4.78/5. Thirty-seven (82.2%) patients declared that they had performed the exercises, all caregivers declared that it was possible to perform the proposed exercises a few times a week or daily, and only two respondents replied to invitations to individual online sessions. CONCLUSIONS: Findings from the study show that respiratory telerehabilitation may be implemented for DMD patients; however, the interest in digital rehabilitation among caregivers of DMD boys in Poland is low. The reasons for this situation require further research.

Therapeutic respiratory and functional rehabilitation protocol for intensive care unit patients affected by COVID-19: a structured summary of a study protocol for a randomised controlled trial.

OBJECTIVES: The primary objective of the presented study is to analyze the respiratory and functional effects of a rehabilitation program in patients affected by hospitalization in Intensive Care Unit (ICU) due to COVID-19, in comparison with the group treated with standard of care, at discharge endpoint. The secondary objectives of the presented study are to evaluate different outcomes of the rehabilitation program in comparison to standard of care regarding: functional performance at 4-week and 12-week post- discharge mark; health-related quality of life, the impact on the health services (namely days of hospitalization), the cost-effectiveness of the intervention proposed. TRIAL DESIGN: This is a randomized, controlled, double-blind, double-arm clinical trial of treatment, with an allocation ratio 1:1 and framework of superiority. PARTICIPANTS: The study will be conducted at Centro Hospitalar Entre Douro e Vouga, Santa Maria da Feira, Portugal. Potential participants will be adult patients (≥18 years old) hospitalized in ICU with respiratory insufficiency due to COVID-19, who are referred to respiratory and functional rehabilitation. Only patients approved by physical rehabilitation doctors to perform respiratory and functional rehabilitation will be considered potential participants. To be eligible for inclusion participants must have been independent in their activities of daily living before the onset of critical illness (verbal statement by their proxy) and have to meet the safety criteria defined by the Portuguese Society of Physical Rehabilitation Medicine. INTERVENTION AND COMPARATOR: Both groups will receive usual medical and nursing care in the ICU, which involves assessment and treatment of the respiratory system and may include positioning, hyperinflation techniques and suctioning. The physical function of the patient is assessed, and active bed exercises and mobility are encouraged as soon as possible and may include sitting out of bed. The intervention group will receive a functional and respiratory multidisciplinary rehabilitation protocol (that includes medical, nursing, physiotherapy and occupational therapy interventions) during their entire hospital stay. After reassurance that the patients fulfil the safety criteria, they will initiate the rehabilitation protocol, individualized to each patient based on the clinical status. The rehabilitation interventions and exercises implemented will be consistent with recommendations from the Portuguese Society of Physical Rehabilitation Medicine. The intervention will occur 6 days per week (Monday to Saturday), fifteen minutes, twice per day for each participant. Throughout all activities, progression will be increased successively, depending on the individual's tolerance and stability. After discharge, the intervention group will continue with rehabilitation exercises, prescribed by physical rehabilitation doctors. These exercises are designed for the patient to do at home, and then report their execution to rehabilitation nurses through teleconsultation, until 12 weeks after ICU discharge. MAIN OUTCOMES: Baseline descriptive data collection will include age, sex, comorbidities and date of admission to ICU. The need of mechanical ventilation and length of use, as well as the need for oxygen therapy, length of ICU stay (days/hours), incidence of ICU readmission, discharge destination and survival will also be recorded. Prior to intervention, every two days and at discharge, participants will be evaluated using the following scales: Glasgow Coma Scale, Richmond Agitation Sedation Scale, Chelsea Critical Care Physical Assessment, 5 standardized questions for cooperation, Medical Research Council Sum-Score, Handgrip strength test and Medical Research Council dyspnea scale. At discharge, Borg Rating of Perceived Exertion will be evaluated. The primary outcome measure will be functional capacity using the 6-Minute Walk Test, and it will be measured at discharge and at the 4-week and 12-week mark. Medical Research Council Sum-Score, Handgrip strength test, Medical Research Council dyspnea scale and Borg Rating of Perceived Exertion will also be re-evaluated at the 4-week and 12-week mark. The health related quality of life will also be used as an outcome measure, using the 12-Item Short Form Survey, at 12 weeks of follow-up. RANDOMISATION: Participants will be divided into two groups, standard care and intervention, by means of balanced randomization at a 1:1 ratio using blocks of 10 participants. The randomization sequence is going to be created using a free software ( http://www.randomized.org/ ). In order to ensure the confidentiality of the randomisation sequence, this process will be conducted by an assessor external to the study. BLINDING (MASKING): The evaluators in the study will be blinded during the entire process. The evaluators will be unaware of the study objectives and the randomized distribution of patients to study groups and will not have access to the randomization sequence. Although blinding for patients will not be possible to achieve completely, subjects will be unaware of other treatment modalities, and they will not know if they belong to the intervention or standard group. As for the treating physiotherapists and ICU staff, blinding will not be possible to achieve, but they will not be responsible for assessing outcomes. NUMBERS TO BE RANDOMISED (SAMPLE SIZE): We plan to randomise 40 participants to each group. 80 participants in total. TRIAL STATUS: This is the second and definitive protocol version, dated from 26th February 2021. Recruitment started on 8th March 2021. Participants will be recruited between March 8, 2021, and June 8, 2021. Study completion is expected to be October 2021. TRIAL REGISTRATION: ReBEC RBR-7rvhpq9 . Registry name: The effect of rehabilitation in hospitalized COVID-19 patients. Registered on 17 March 2021.Retrospectively registered. FULL PROTOCOL: "The full protocol is attached as an additional file, accessible from the Trials website (Additional file 1). In the interest in expediting dissemination of this material, the familiar formatting has been eliminated; this Letter serves as a summary of the key elements of the full protocol".

[Therapeutic education for people with chronic respiratory disease]. / Éducation thérapeutique des personnes atteintes de maladie respiratoire chronique.

The physiotherapist's practice involves taking care of patients with various chronic pathologies: neurological, rheumatic, respiratory, etc. The physiotherapist must carry out an educational approach in these patients, at the same time as the physical work of re-education, in order to induce behavioural changes beneficial to their physical and psychological health and to empower them in the best possible way in the management of their pathology.

[Recommendation of respiratory rehabilitation for PICS in critically ill patients with COVID-19].

The critically illsurvivors with COVID-19 have Post-Intensive Care Syndrome (PICS) manifestations of varying degrees of physical, cognitive, and mental disorders after discharge from the Intensive Care Unit. Comprehensive respiratory rehabilitation interventions for patients are essential to minimize disability rate, reduce medical costs, and increase social participation. Integrated the existing treatment experience and relevant literature evidence, we recommend the evaluation and intervention of respiratory rehabilitation in the two stages of discharge ICUto ward and home. Based on Chinese experience, a PCCM physician-led multidisciplinary team management process was constructed. Personal protection recommendations were made based on the potential risk of infection among critically ill COVID-19 survivors.

Rehabilitation of patients with COVID-19.

INTRODUCTION: In 2020, due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), coronavirus disease (COVID-19) has become a pandemic. As of 11 August 2020, the cumulative number of confirmed cases worldwide had reached 19 million, with 700,000 reported deaths, indicating this pandemic's significant global impact. AREAS COVERED: We reviewed the application of rehabilitation therapy in the clinical treatment of COVID-19 patients. A systematic search was performed using PubMed, Springer, CNKI, and Wanfang Data of database up to 1 August 2020. The search terms included the English terms and their Chinese equivalents: 'COVID-19,' 'ARDS,' 'rehabilitation,' 'critically ill patients,' 'physiotherapy,' 'respiratory rehabilitation,' 'traditional Chinese medicine,' and 'psychotherapy.' EXPERT OPINION: Rehabilitation research concerning patients with COVID-19 remains ongoing. Rehabilitation guidance for such patients with COVID-19 is based on previous experience. However, as different patients have differing degrees of dysfunction, personalized plans need to be designed according to the patients' age, sex, lifestyle, hobbies, occupation, and physical conditions. The rapid development of remote devices that can monitor patients' real-time physical conditions post-discharge may encourage better adherence to rehabilitation training.

Summary of respiratory rehabilitation and physical therapy guidelines for patients with COVID-19 based on recommendations of World Confederation for Physical Therapy and National Association of Physical Therapy.

[Purpose] To summarize the existing official guidelines issued by the World Confederation for Physical Therapy and Associations of Physical Therapy in various countries and to clarify the recommended methods of respiratory rehabilitation and physiotherapy for patients in different stages of the coronavirus disease of 2019 (COVID-19). [Methods] An introductory literature search was conducted using the keywords "COVID-19", "respiratory rehabilitation", "physical therapy", and others in the database of the Association of Physical Therapy. [Results] Using 12 coronavirus disease-2019 rehabilitation-related articles, we summarized data on physical therapy (PT) evaluation; treatment; indications; contraindications; and termination indicators for patients in acute, stable, and post-discharge stages. [Conclusion] PT for COVID-19 patients with coronavirus disease 2019 should be formulated according to the stage of the disease and condition of the patients.

Respiratory rehabilitation in elderly patients with COVID-19: A randomized controlled study.

BACKGROUND: Different degrees of disorders are reported in respiratory function, physical function and psychological function in patients with corona virus disease 2019 (COVID-19), especially in elderly patients. With the experience of improved and discharged COVID-19 patients, timely respiratory rehabilitation intervention may improve prognosis, maximize functional preservation and improve quality of life (QoL), but there lacks of studies worldwide exploring the outcome of this intervention. OBJECTIVE: To investigate the effects of 6-week respiratory rehabilitation training on respiratory function, QoL, mobility and psychological function in elderly patients with COVID-19. METHODS: This paper reported the findings of an observational, prospective, quasi-experimental study, which totally recruited 72 participants, of which 36 patients underwent respiratory rehabilitation and the rest without any rehabilitation intervention. The following outcomes were measured: pulmonary function tests including plethysmography and diffusing lung capacity for carbon monoxide (DLCO), functional tests (6-min walk distance test), Quality of life (QoL) assessments (SF-36 scores), activities of daily living (Functional Independence Measure, FIM scores), and mental status tests (SAS anxiety and SDS depression scores). RESULTS: After 6 weeks of respiratory rehabilitation in the intervention group, there disclosed significant differences in FEV1(L), FVC(L), FEV1/FVC%, DLCO% and 6-min walk test. The SF-36 scores, in 8 dimensions, were statistically significant within the intervention group and between the two groups. SAS and SDS scores in the intervention group decreased after the intervention, but only anxiety had significant statistical significance within and between the two groups. CONCLUSIONS: Six-week respiratory rehabilitation can improve respiratory function, QoL and anxiety of elderly patients with COVID-19, but it has little significant improvement on depression in the elderly.
