ABSTRACT

Objective:To investigate the effect of early pulmonary rehabilitation (PR) training on the improvement of respiratory function in patients with acute respiratory distress syndrome (ARDS) after weaning of invasive mechanical ventilation in the intensive care unit (ICU).Methods:The retrospective cohort research method was used. The clinical information of adult patients with ARDS receiving invasive mechanical ventilation admitted to the ICU of Qingdao Municipal Hospital from January 2019 to March 2023 was collected. The patients were divided into a control group and an observation group according to off-line training program. The control group received traditional training after weaning, and the observation group received the early PR training after weaning. Other treatments and nursing were implemented according to the routine of the ICU. The scores of the short physical performance battery (SPPB) on day 3-day 6 of the weaning training, respiratory muscle strength, level of interleukin-6 (IL-6), number of aspirations of sputum after weaning, length of stay after weaning, rehospitalization rate within 6 months after discharge, and pulmonary function indicators at discharge and 3 months after discharge [peak expiratory flow (PEF), forced expiratory volume in one second/forced vital capacity ratio (FEV1/FVC), and vital capacity (VC)] of the two groups of patients were compared. The Kaplan-Meier survival curve was drawn to analyze the cumulative survival rate of patients 6 months after discharge.Results:A total of 50 of which 25 cases received the traditional training after weaning, 25 cases received the early PR training after weaning. There was no significant difference in gender, age, acute physiology and chronic health evaluationⅡ (APACHEⅡ), oxygenation index upon admission, etiological diagnosis of ARDS upon admission, time of invasive ventilation, mode of invasive mechanical ventilation, pulmonary function indicators at discharge, and other baseline data of the two groups. The SPPB questionnaire scores and respiratory muscle strength in both groups were increased gradually with the extended offline training time, the serum level of IL-6 in both groups were descend gradually with the extended offline training time, especially in the observation group [SPPB questionnaire score in the observation group were 7.81±0.33, 8.72±0.53, 9.44±0.31, 10.57±0.50, while in the control group were 7.74±0.68, 8.73±0.37, 8.72±0.40, 9.33±0.26, effect of time: F = 192.532, P = 0.000, effect of intervention: F = 88.561, P = 0.000, interaction effect between intervention and time: F = 24.724, P = 0.000; respiratory muscle strength (mmHg, 1 mmHg≈0.133 kPa) in the observation group were 123.20±24.84, 137.00±26.47, 149.00±24.70, 155.40±29.37, while in the control group were 129.00±20.34, 126.00±24.01, 132.20±25.15, 138.60±36.67, effect of time: F = 5.926, P = 0.001, effect of intervention: F = 5.248, P = 0.031, interaction effect between intervention and time: F = 3.033, P = 0.043; serum level of IL-6 in the observation group were 80.05±6.81, 74.76±9.33, 63.66±10.19, 56.95±4.72, while in the control group were 80.18±7.21, 77.23±9.78, 71.79±10.40, 66.51±6.49, effect of time: F = 53.485, P = 0.000, effect of intervention: F = 22.942, P = 0.000, interaction effect between intervention and time: F = 3.266, P = 0.026]. Compared with the control group, the number of aspirations of sputum after weaning of patients in the observation group significantly decreased (number: 22.46±1.76 vs. 27.31±0.90), the length of ICU stay after weaning significantly became shorter (days: 6.93±0.95 vs. 8.52±2.21), and the rehospitalization rate within 6 months after discharge significantly decreased [20.00% (5/25) vs. 48.00% (12/25)]. There were significant differences. The pulmonary function indicators 3 months after discharge of two groups of patients significantly increased compared with those at discharge and those of the observation group were significantly higher than those of the control group [PEF (L/min): 430.20±95.18 vs. 370.00±108.44, FEV1/FVC ratio: 0.88±0.04 vs. 0.82±0.05, VC (L): 3.22±0.72 vs. 2.74±0.37, all P < 0.05]. The Kaplan-Meier survival curve showed that the cumulative survival rate of patients 6 months after discharge of patients in the observation group was significantly higher than that of patients in the control group [76.9% vs. 45.5%, hazard ratio ( HR) = 0.344, P = 0.017]. Conclusion:Early PR training can significantly improve the respiratory function of patients with ARDS after weaning of invasive mechanical ventilation. Continuous active respiratory training after discharge can improve the respiratory function of patients and effectively decrease mortality.

ABSTRACT

ABSTRACT Introduction: This study aimed to evaluate the efficacy of respiratory muscle training during the immediate postoperative period of cardiac surgery on respiratory muscle strength, pulmonary function, functional capacity, and length of hospital stay. Methods: This is a systematic review and meta-analysis. A comprehensive search on PubMed®, Excerpta Medica Database (or Embase), Cumulative Index of Nursing and Allied Health Literature (or CINAHL), Latin American and Caribbean Health Sciences Literature (or LILACS), Scientific Electronic Library Online (or SciELO), Physiotherapy Evidence Database (or PEDro), and Cochrane Central Register of Controlled Trials databases was performed. A combination of free-text words and indexed terms referring to cardiac surgery, coronary artery bypass grafting, respiratory muscle training, and clinical trials was used. A total of 792 studies were identified; after careful selection, six studies were evaluated. Results: The studies found significant improvement after inspiratory muscle training (IMT) (n = 165, 95% confidence interval [CI] 9.68, 21.99) and expiratory muscle training (EMT) (n = 135, 95% CI 8.59, 27.07) of maximal inspiratory pressure and maximal expiratory pressure, respectively. Also, IMT increased significantly (95% CI 19.59, 349.82, n = 85) the tidal volume. However, no differences were found in the peak expiratory flow, functional capacity, and length of hospital stay after EMT and IMT. Conclusion: IMT and EMT demonstrated efficacy in improving respiratory muscle strength during the immediate postoperative period of cardiac surgery. There was no evidence indicating the efficacy of IMT for pulmonary function and length of hospital stay and the efficacy of EMT for functional capacity.

ABSTRACT

ABSTRACT Introduction: The analysis of patients submitted to heart surgery at three assessment times has been insufficiently described in the literature. Objective: To analyze chest expansion, maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), distance traveled on the six-minute walk test (6MWT), and quality of life in the preoperative period, fourth postoperative day (4th PO), and 30th day after hospital discharge (30th-day HD) in individuals submitted to elective heart surgery. Methods: A descriptive, analytical, cross-sectional study was conducted with 15 individuals submitted to elective heart surgery between 2016 and 2020 who did not undergo any type of physiotherapeutic intervention in Phase II of cardiac rehabilitation. The outcome variables were difference in chest expansion (axillary, nipple, and xiphoid), MIP, MEP, distance on 6MWT, and quality of life. The assessment times were preoperative period, 4th PO, and 30th-day HD. Results: Chest expansion diminished between the preoperative period and 4th PO, followed by an increase at 30th-day HD. MIP, MEP, and distance traveled on the 6MWT diminished between the preoperative period and 4th PO, with a return to preoperative values at 30th-day HD. General quality of life improved between the preoperative period and 4th PO and 30th-day HD. An improvement was found in the social domain between the preoperative period and the 30th-day HD. Conclusion: Heart surgery causes immediate physical deficit, but physical functioning can be recovered 30 days after hospital discharge, resulting in an improvement in quality of life one month after surgery.

ABSTRACT

  Purpose: This study aimed to investigate the effects of underwater walking for 6 weeks at 60% of the predicted maximum heart rate on respiratory muscle strength of elderly people as well as its sustained effects on respiratory muscle strength.  Methods: The participants were 43 healthy elderly men, who were randomly divided into the continuous group (n=21) and the non-continuous group (n=22). Initially, both groups performed 30 min of underwater walking four times a week for 6 weeks, after which the continuous group continued the same for another 6 weeks, whereas the non-continuous group was prohibited from performing any exercise, except for daily activities. The walking speed during underwater walking was adjusted such that the exercise intensity was 60% of the predicted maximum heart rate, with the water depth up to the fourth intercostal space or higher.   Outcome Measures: The maximal inspiratory pressure (PImax), maximal expiratory pressure (PEmax), and vital capacity (VC) were measured before exercise and 6, 8, 10, and 12 weeks after exercise.   Results: The PImax and PEmax were significantly higher after 6 weeks of exercise than those before exercise. In the continuation group, PEmax increased significantly at 12 weeks of exercise compared to that at 6 weeks, whereas PImax did not show a significant increase. In the non-continuous group, PEmax decreased significantly from the 10th week onwards as compared to that at 6 weeks and showed a significantly lower value than that of the continuous group. The PImax of the non-continuous group decreased significantly at 12 weeks compared to that at 6 weeks. The VC after the 6-week underwater walking program did not differ from the pre-exercise value, with no significant difference observed between the two groups. Moreover, the VC in both groups showed no significant changes after 12 weeks of underwater walking compared to that after 6 weeks.  Conclusions: Because underwater walking involves moving forward while resisting water pressure, it is necessary to activate the expiratory abdominal muscles to stabilize the trunk. Notably, the respiratory muscle strength in the non-continuous group decreased 4-6 weeks after the underwater walking program was terminated.

ABSTRACT

Introducción. Determinar el efecto de ocho semanas de entrenamiento por hiperpnea isocápnica voluntaria (HIV) sobre el costo energético asociado a la respiración (COB) reflejado en los cambios en la oxigenación de los músculos intercostales (∆SmO2-m. intercostales) inducida por ejercicio físico de intensidad incremental. Métodos. Doce participantes físicamente activos fueron entrenados durante ocho semanas de HIV 3 días x semana, 12 minutos, al 60% de ventilación voluntaria máxima (VVM). En la semana previa y posterior al entrenamiento HIV se realizó un test cardiopulmonar (CPET) de intensidad incremental en cicloergómetro, durante esta prueba se registró la ∆SmO2-m. intercostales mediante el dispositivo MOXY®. El efecto de HIV sobre la ∆SmO2-m. intercostales se analizó mediante la prueba two-way mixed ANOVA considerando los factores (fase × tarea). Resultados. ∆SmO2-m.intercostales fue significativamente menor a partir del 30% (­5,0±4,7%; p<0.01) hasta el 100% (­10,6±12,8%; p<0.01) de la tarea luego de ocho semanas de HIV. Además, se reportó un aumento de la presión inspiratoria máxima (PIM)=16,5±11,4 cmH2O (p<0.01); y de la resistencia muscular respiratoria=106,6±149,0 s (p<0.01). El tiempo total de ejercicio aumentó en 106,6±149,0 s (p=0.04), así como la carga total en 10,50± 10,12 vatios (p<0.01). Conclusión. El HIV disminuye el COB inducido por ejercicio incremental asociado a un incremento en la performance física y de los músculos respiratorios. En futuros estudios se sugiere estudiar esta estrategia de entrenamiento analítico de los músculos respiratorios en usuarios con limitación física relacionada al aumento prematuro del COB.


Background. Objetive. To determine the effect of eight weeks of voluntary isocapnic hyperpnea (VIH) training on cost of breathing (COB) as reflected by intercostales muscles deoxygenation (∆SmO2-m. intercostales) induced by incremental-intensity physical exercise. Methods. Twelve physically active participants underwent eight weeks of VIH training, three days a week, for 12 minutes each session, at 60% of maximal voluntary ventilation (MVV). In the week before and after VIH training, a cardiopulmonary test (CPET) of incremental intensity was performed on a cycloergometer. During this test, intercostal ∆SmO2-m.intercostales was recorded using the MOXY® device. The effect of VIH on ∆SmO2-m.intercostales were analyzed using a two-way mixed ANOVA test considering the factors (phase × task). Results. ∆SmO2-m.intercostales significantly decreased from 30% (­5.0±4.7%; p<0.01) to 100% (­10.6±12.8%; p<0.01) of the task after eight weeks of VIH. Additionally, an increase in maximal inspiratory pressure (MIP) of 16.5±11.4 cmH2O (p<0.01) and respiratory muscle endurance of 106.6±149.0 s (p<0.01) was reported. Total exercise time increased by 106.6±149.0 s (p=0.04), as well as total workload by 10.50±10.12 watts (p<0.01). Conclusion. VIH reduces COB induced by incremental exercise and is associated with increased physical and respiratory muscle performance. Future studies should explore this respiratory muscle training strategy for individuals with physical limitations related to a premature increase in COB.

ABSTRACT

Background: Assessing respiratory muscle strength is an important aspect for clinical practice as well as in research. Multiple factors such as health status of an individual, level of physical fitness and postsurgical recovery of an individual have an influence on respiratory biomechanics. Respiratory muscle strength is determined by measuring maximal inspiratory pressure and maximal expiratory pressure. There is a need for a cost effective, portable, easy to build device specifically to estimate respiratory muscle strength. There is insufficient literature regarding the resources used to determine the respiratory muscle strength testing in children, hence this study aims to establish the reliability and validity of low cost pressure gauge manometer which could be a useful tool in measuring respiratory muscle strength in children. Methods: A capsule sensing pressure gauge constructed according to the American thoracic society guidelines with a calibration of pressure between ?200 cmH2O to +200 cmH2O. It was used to measure the respiratory muscle strength. The study was conducted on 300 healthy children. Results: SPSS software was used for statistical analysis. Reliability of 0.92 and 0.97 was obtained for MIP and MEP respectively by test retest method. Construct validity index showed a validity score of 0.8 for MIP and MEP. Conclusions: The results indicate that the low cost pressure gauge manometer can be used as a reliable and valid device to measure respiratory muscle strength in children.

ABSTRACT

ABSTRACT Introduction: People with type 2 diabetes mellitus present multiple complications and comorbidities, such as peripheral autonomic neuropathies and reduced peripheral force and functional capacity. Inspiratory muscle training is a widely used intervention with numerous benefits for various disorders. The present study aimed to conduct a systematic review to identify inspiratory muscle training effects on functional capacity, autonomic function, and glycemic indexes in patients with type 2 diabetes mellitus. Methods: A search was carried out by two independent reviewers. It was performed in PubMed®, Cochrane Library, Latin American and Caribbean Literature in Health Sciences (or LILACS), Physiotherapy Evidence Database (PEDro), Embase, Scopus, and Web of Science databases. There were no restrictions of language or time. Randomized clinical trials of type 2 diabetes mellitus with inspiratory muscle training intervention were selected. Studies' methodological quality was assessed using PEDro scale. Results: We found 5,319 studies, and six were selected for qualitative analysis, which was also conducted by the two reviewers. Methodological quality varied - two studies were classified as high quality, two as moderate quality, and two as low quality. Conclusion: It was found that after inspiratory muscle training protocols, there was a reduction in the sympathetic modulation and an increase in functional capacity. The results should be carefully interpreted, as there were divergences in the methodologies adopted, populations, and conclusions between the studies evaluated in this review.

ABSTRACT

The "timed inspiratory effort" (TIE) index, a new predictor of weaning outcome, normalizes the maximal inspiratory pressure with the time required to reach this value up to 60 s, incorporating the time domain into the assessment of inspiratory muscle function. The objective of this study was to determine whether the TIE predicts successful extubation at a similar rate as the T-piece trial with less time required. A non-inferiority randomized controlled trial was performed with ICU subjects eligible for weaning. The participants were allocated to the TIE or the T-piece groups. The primary outcome was successful weaning, and the main secondary outcome was ICU mortality. Eighty participants of each group were included in the final analysis. Time from the start of a successful test to effective extubation was significantly lower in the TIE group than in the T-piece group, 15 (10 to 24) vs 55 (40 to 75) min, P<0.001. In the Kaplan-Meier analysis, no significant differences were found in successful weaning (79.5 vs 82.5%, P=0.268) or survival rate (62.9 vs 53.8%, P=0.210) between the TIE and T-piece groups at the 30th day. In this preliminary study, the TIE index was not inferior to the T-piece trial as a decision-making tool for extubation and allowed a reduction in the decision time.

ABSTRACT

It has been reported that using of the spine mat increases chest expansion, inspiratory capacity (IC) and maximum inspiratory mouth pressure (PImax). However, no changes were observed in other respiratory functions and the respiratory muscle strength. The purpose of this study was to clarify the effects of pursed-lip breathing lying on the spine mat to the respiratory function and respiratory muscle strength. Forty-two adult male participants were assigned to two groups; an intervention group (IG group) of 21 participants who performed pursed-lip breathing on top of a spine mat and a control group (CG group) of 21 participants who performed pursed-lip breathing only. The intervention period was 5 days, and the respiratory features evaluated were chest expansion, respiratory function, respiratory muscle strength, and spinal alignment. A significant increase between the Pretest and the Posttest in chest expansion at the circumference of the axilla level, of the xiphoid process level and of the 10th rib level was observed only in IG group. For the respiratory function and the respiratory muscle strength, intervention group showed significant increases in percentage of vital capacity (%VC), tidal volume (TV), PImax, and maximum expiratory mouth pressure (PEmax). In the control group, only the TV indicated a significant increase. Regarding changes before and after the intervention, the intervention group showed significantly higher PImax and PEmax than the control group. No significant difference in spinal alignment was observed between the two groups. These results showed that pursed-lip breathing lying on the spine mat would increase the PImax, PEmax and the chest expansion.

ABSTRACT

OBJECTIVE@#To evaluate the feasibility and safety of Liuzijue exercise (LE) for the clinical effect in patients after cardiac surgery.@*METHODS@#Totally 120 patients who underwent cardiac surgery and were admitted to the Cardiothoracic Intensive Care Unit of Nanjing Drum Tower Hospital between July and Oclober, 2022 were allocated to the LE group, the conventional respiratory training (CRT) group, and the control group by a random number table at a ratio of 1:1:1; 40 patients in each group. All patients received routine treatment and cardiac rehabilitation. LE group and CRT group respectively performed LE and CRT once a day for 30 min for 7 days. Control group did not receive specialized respiratory training. The forced vital capacity, forced expiratory volume in 1 s, peak inspiratory flow rate, peak expiratory flow rate, maximum inspiratory pressure, maximum expiratory pressure, modified Barthel index (MBI), and Hamilton Rating Scale for Anxiety (HAM-A) were evaluated before, after 3 and 7 days of intervention. In addition, the postoperative length of hospital stay (LOS) and the adverse events that occurred during the intervention period were compared.@*RESULTS@#A total of 107 patients completed the study, 120 patients were included in the analysis. After 3 days of intervention, the pulmonary function, respiratory muscle strength, MBI and HAM-A of all 3 groups improved compared with that before the intervention (P<0.05 or P<0.01). Compared with the control group, pulmonary function and respiratory muscle strength were significantly improved in the CRT and LE groups (P<0.05 or P<0.01). MBI and HAM-A were significantly improved in the LE group compared with the control and CRT groups (P<0.05 or P<0.01). On the 7th day after intervention, the difference was still statistically significant (P<0.01), and was significantly different from that on the 3rd day (P<0.05 or P<0.01). In addition, on the 7th day of intervention, the pulmonary function and respiratory muscle strength in the LE group were significantly improved compared with those in the CRT group (P<0.01). MBI and HAM-A were significantly improved in the CRT group compared with the control group (P<0.01). There were no significant differences in postoperative LOS among the 3 groups (P>0.05). No training-related adverse events occurred during the intervention period.@*CONCLUSIONS@#LE is safe and feasible for improving pulmonary function, respiratory muscle strength, the ability to complete activities of daily living and for relieving anxiety of patients after cardiac surgery (Registration No. ChiCTR2200062964).

ABSTRACT

SUMMARY BACKGROUND: The infection caused by coronavirus disease 2019 can lead to respiratory sequelae in individuals who have experienced severe or mild symptoms. METHODS: An observational, cross-sectional study was developed, following the STROBE guidelines. Maximal inspiratory and expiratory mouth pressures were assessed in 50 healthy young students (26 women, 24 men; age 22.20±2.41 years). The inclusion criteria were as follows: aged between 18 and 35 years; control group: not diagnosed with coronavirus disease 2019; and coronavirus disease 2019 group: diagnosed with coronavirus disease 2019, at least 6 months ago. The exclusion criteria were as follows: obese/overweight; infected with coronavirus disease 2019 or coronavirus disease 2019 symptoms in the last 6 months; smokers; and asthmatics. RESULTS: When comparing with groups, the coronavirus disease 2019 group presented statistically significant lower maximal inspiratory pressure values compared with the control group (88.32±16.62 vs. 101.01±17.42 cm H2O; p=0.01). Regarding the maximal expiratory pressure, no significant differences were found. Similar results were found when performing a subgroup analysis by sex and group. CONCLUSIONS: Young students who suffered from coronavirus disease 2019 asymptomatically or mildly at least 6 months ago presented a significant decrease in the inspiratory muscle strength as a sequel, so we believe that patients affected by this disease should have a brief postinfection assessment of this musculature to detect the indication for cardiorespiratory rehabilitation.

ABSTRACT

Objective:To explore any effect of high-intensity inspiratory muscle resistance training on exercise capacity and life quality for persons with bronchiectasis.Methods:Sixty patients with bronchiectasis were randomly divided into an observation group and a control group, each of 30. The observation group received two 30-minute sessions of inspiratory muscle resistance training daily using the PowerBreak inspiratory muscle trainer 3 days/week for 8 weeks. The intensity was 70% of the maximum inspiratory pressure (MIP). The control group underwent the same training with the intensity at 10% of the MIP. The severity of illness, pulmonary function, respiratory muscle strength and endurance, exercise capacity and life quality of the two groups were evaluated before and after the intervention.Results:Compared with before the intervention, the average MIP in the observation group and the average distance they walked in the 6min walk test (6MWT) improved significantly. Their average social factor score on the Leicester cough questionnaire had increased significantly, while their average heart rate and self-perceived exertion during the 6MWT had decreased significantly. There were no significant differences in any of these indicators for the control group.Conclusions:High-intensity inspiratory muscle resistance training can significantly improve the exercise capacity and life quality of patients with bronchiectasis. The treatment is worthy of further research and application in the clinic.

ABSTRACT

Objective:To observe the effect of combining respiratory muscle training with occupational therapy in rehabilitating the upper limb function of stroke survivors.Methods:Fifty stroke survivors with upper limb dysfunction were randomly divided into an observation group and a control group, each of 25. Both groups were given routine rehabilitation treatment including proper positioning of the affected limb, physical therapy and motor function training. The observation group also received progressive resistance training of the inspiratory muscles and respiration control training combined with occupational therapy twice daily for 4 weeks. The trunk control test (TCT), Berg balance scale (BBS), Fugl-Meyer Upper Extremity Assessment (FMA-UE), Action Research Arm Test (ARAT), Modified Ashworth Scale (MAS) for the Hemiplegic Upper Limb and the Modified Barthel Index (MBI) were used to assess the core stability, balance, upper limb functioning, upper limb muscle tension and ability in the activities of daily living of all of the subjects.Results:Before the treatment there were no significant differences in any of the indexes between the two groups. Afterward the average TCT, BBS, FMA-UE, ARAT, MAS and MBI scores of both groups had improved significantly, but the improvements were all significantly greater in the observation group.Conclusions:Combining respiratory muscle training with occupational therapy can further improve the function of the upper limbs and daily living ability beyond what is observed with traditional rehabilitation therapy after a stroke.

ABSTRACT

Objective:To explore the effect of inspiratory muscle training (IMT) on the pulmonary functioning, respiratory muscle strength and endurance of morbidly obesity persons after bariatric surgery.Methods:Thirty-six morbidly obese patients undergoing bariatric surgery were randomly divided into an experimental group and a control group. A 20-minute daily IMT intervention was administered on the 2nd through the 30th day after the operation. The intensities were 40% and 5% of the maximum inspiratory pressure (MIP). Forced vital capacity, forced expiratory volume in 1 second, maximum peak expiratory flow, maximum inspiratory pressure (MIP) and maximum expiratory pressure, as well as endurance were measured before the operation and on the 2nd, 7th, 14th and 30th day afterward.Results:By the 7th day the pulmonary function of the experimental group had recovered to the level before the operation. For the control group that took until the 14th day. On the 30th day after the operation the average MIP and inspiratory muscle endurance of the experimental group had increased significantly compared with before the operation, while the average MIP of the control group had decreased significantly.Conclusions:Inspiratory muscle training can improve inspiratory muscle strength and endurance and accelerate the recovery of lung function of morbidly obese persons after bariatric surgery.

ABSTRACT

Objective:To observe any short-term effect of combining respiratory muscle training with feedback respiratory electrical stimulation on the pulmonary function and respiratory muscle strength of stroke survivors.Methods:Sixty stroke survivors were randomly divided into an observation group ( n=30) and a control group ( n=30). Both groups were given conventional rehabilitation 6 days a week for 3 weeks, but the observation group also received respiratory muscle training with feedback electrical stimulation. Before and after the treatment, both groups′ pulmonary functioning and respiratory muscle strength were measured, and also their trunk control, skill in the activities of daily living and fatigue level. The trunk impairment scale (TIS), modified Barthel index (MBI) and fatigue severity scale (FSS) were used. The incidence of stroke-associated pneumonia (SAP) was also compared between the two groups. Results:After the treatment, average forced vital capacity, forced expiratory volume in 1 second, maximum voluntary ventilation, peak expiratory flow, maximum inspiratory pressure, maximum expiratory pressure, as well as the average TIS and MBI scores of both groups had improved significantly, and there was a significant decrease in the average FSS scores. After the intervention, all of the average measurements of the experimental group were significantly better than the control group′s averages except their MBI scores. There was no significant difference in the incidence of SAP.Conclusions:Three weeks of respiratory muscle training combined with electrical stimulation feedback can effectively improve the pulmonary function, respiratory muscle strength and inspiratory muscle endurance of stroke survivors, resulting in better coughing ability, trunk control and reduced fatigue.

ABSTRACT

The aim of this randomized controlled trial was to analyze the effects of an inspiratory muscle training (IMT) program on apnea and hypopnea index (AHI), inspiratory muscle strength, sleep quality, and daytime sleepiness in individuals with obstructive sleep apnea (OSA), whether or not they used continuous positive airway pressure (CPAP (+/−) therapy. The intervention group underwent IMT with a progressive resistive load of 40-70% of the maximum inspiratory pressure (PImax) for 30 breaths once a day for 12 weeks. The control group was submitted to a similar protocol, but with at a minimum load of 10 cmH2O. Changes in the AHI were the primary outcome. PImax was measured with a digital vacuometer, daytime somnolence was measured by the Epworth sleepiness scale (ESS), and the quality of sleep by the Pittsburgh Sleep Quality Index (PSQI). CPAP use was treated as a confounder and controlled by stratification resulting in 4 subgroups: IMT−/CPAP−, IMT−/CPAP+, IMT+/CPAP−, and IMT+/CPAP+. Sixty-five individuals were included in the final analysis. Significant variations were found in the 4 parameters measured throughout the study after the intervention in both CPAP− and CPAP+ participants: PImax was increased and AHI was reduced, whereas improvements were seen in both ESS and PSQI. The twelve-week IMT program increased inspiratory muscle strength, substantially reduced AHI, and had a positive impact on sleep quality and daytime sleepiness, whether or not participants were using CPAP. Our findings reinforce the role of an IMT program as an adjunct resource in OSA treatment.

ABSTRACT

Objective This living systematic review aims to provide a timely, rigorous and continuously updated summary of the evidence available on the role of pulmonary rehabilitation in the treatment of patients with COVID-19. Design This is the protocol of a living systematic review. Data sources We will conduct searches in the L·OVE (Living OVerview of Evidence) platform for COVID-19, a system that maps PICO questions to a repository maintained through regular searches in electronic databases, preprint servers, trial registries and other resources relevant to COVID-19. No date or language restrictions will be applied. Eligibility criteria for selecting studies and methods We adapted an already published common protocol for multiple parallel systematic reviews to the specificities of this question. We will include randomized trials evaluating the effect of pulmonary rehabilitation as monotherapy or in combination with other interventions-versus sham or no treatment in patients with COVID-19. Two reviewers will independently screen each study for eligibility, extract data, and assess the risk of bias. We will pool the results using meta-analysis and will apply the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to assess the certainty of the evidence for each outcome. Ethics and dissemination No ethics approval is considered necessary. The results of this review will be widely disseminated via peer-reviewed publications, social networks and traditional media.
