A multi-center randomized controlled trial to investigate potential effects of exercise therapy on renal function stratified by renal disorders and renal pathology: beneficial or harmful effect in immunoglobulin a nephropathy. Clin Exp Nephrol 2024; 28:539-546. [PMID: 38402501 DOI: 10.1007/s10157-024-02461-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Accepted: 01/09/2024] [Indexed: 02/26/2024]
Abstract
BACKGROUND The effects of exercise therapy (ET) on renal function in chronic kidney disease (CKD) remain unclear. METHODS In a randomized controlled trial (UMIN-CTR number: UMIN000038415), we investigated whether ET affects renal function in CKD; eligible patients had undergone renal biopsy in the past 3 months. We stratified patients by disease (immunoglobulin A [IgA] nephropathy, n = 16; diabetic nephropathy, n = 4; benign nephrosclerosis, n = 13; and other CKD types, n = 13) and randomized them to 12 weeks' observation and 24 weeks' ET comprising home-based aerobic exercise 3×/week and resistance training 2×/week (intervention group) or usual care (non-intervention group). Primary endpoint was creatinine-based estimated glomerular filtration rate (eGFR) or serum cystatin C-based eGFR (eGFRcys). Secondary endpoints included urinary protein and exercise tolerance. RESULTS Seventy patients were enrolled, 50 fulfilled the inclusion criteria, but 4 discontinued before randomization. No items significantly differed between week 0 to 24 in either group (intervention group, n = 23; non-intervention group, n = 23) or between groups at week 24 (intention-to-treat population) in the total study population. The eGFRcys slope showed no significant intergroup difference in the observation period, but eGFRcys improved significantly in IgA nephropathy patients (n = 16) in the intervention group (stratified comparison; week 0, 48.3 ± 18.2; week 24, 51.6 ± 17.6; p = 0.043). In these patients, urinary protein was significantly worse at week 24 in the non-intervention group (p = 0.046) and worsened significantly less in the intervention group (p = 0.039). CONCLUSION ET did not improve renal function overall in CKD patients but might help maintain renal function in patients with IgA nephropathy.

Evaluating a Remotely Delivered Cardio-Oncology Rehabilitation Intervention for Patients With Breast Cancer (REMOTE-COR-B): Protocol for a Single-Arm Feasibility Trial. JMIR Res Protoc 2024; 13:e53301. [PMID: 38578682 PMCID: PMC11031702 DOI: 10.2196/53301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 01/18/2024] [Accepted: 01/19/2024] [Indexed: 04/06/2024] Open
Abstract
BACKGROUND Exercise rehabilitation is a promising strategy for reducing cardiovascular disease risk among patients with breast cancer. However, the evidence is primarily derived from programs based at exercise centers with in-person supervised delivery. Conversely, most patients report a preference for home-based rehabilitation. As such, there is a clear need to explore strategies that can provide real-time supervision and coaching while addressing consumer preferences. Evidence from cardiac rehabilitation has demonstrated the noninferiority of a smartphone-based telerehabilitation approach (REMOTE-CR) to improve cardiorespiratory fitness in people with cardiovascular disease compared to a center-based program. OBJECTIVE This study aims to assess the feasibility, safety, and preliminary efficacy of the REMOTE-CR program adapted for patients with breast cancer at risk of cardiotoxicity (REMOTE-COR-B). We will also assess the satisfaction and usability of REMOTE-COR-B. METHODS We will conduct a single-arm feasibility study of the REMOTE-COR-B program among patients with stage I-III breast cancer who are at risk of cardiotoxicity (taking treatment type and dose, as well as other common cardiovascular disease risk factors into account) and who are within 24 months of completing primary definitive treatment. Participants (target sample size of 40) will receive an 8-week smartphone-based telerehabilitation exercise program involving remotely delivered real-time supervision and behavior change support. The platform comprises a smartphone and wearable heart rate monitor, as well as a custom-built smartphone app and web application. Participants will be able to attend remotely monitored exercise sessions during set operating hours each week, scheduled in both the morning and evening. Adherence is the primary outcome of the trial, assessed through the number of remotely monitored exercise sessions attended compared to the trial target (ie, 3 sessions per week). Secondary outcomes include additional trial feasibility indicators (eg, recruitment and retention), safety, satisfaction, and usability, and objective and patient-reported efficacy outcomes (cardiovascular fitness, quality of life, fatigue, self-reported exercise, self-efficacy, habit strength, and motivation). Adherence, feasibility, and safety outcomes will be assessed during the intervention period; intervention satisfaction and usability will be assessed post intervention; and objective and patient-reported efficacy outcomes will be assessed at baseline, post intervention (2-month postbaseline assessment), and at follow-up (5-month postbaseline assessment). RESULTS Recruitment for this trial commenced in March 2023, and 7 participants had been recruited as of the submission of the manuscript. The estimated completion date for the project is October 2024, with results expected to be published in mid-2025. CONCLUSIONS The REMOTE-COR-B intervention is a novel and promising approach to providing exercise therapy to patients with breast cancer at risk of cardiotoxicity who have unique needs and heightened safety risks. This project will provide important information on the extent to which this approach is satisfactory to patients with breast cancer, safe, and potentially effective, which is necessary before larger-scale research or clinical projects.

Abstract
OBJECTIVE To investigate the feasibility of submaximal cardiopulmonary exercise testing (CPET) in patients with knee osteoarthritis (OA) scheduled for primary total knee arthroplasty (TKA) surgery. Secondly, to assess their preoperative aerobic capacity. METHODS In this observational, single-center study, participants performed a submaximal CPET 3-6 weeks before surgery. To examine their experiences, participants completed a questionnaire and one week later they were contacted by telephone. CPET was deemed feasible when five feasibility criteria were met. Aerobic capacity was evaluated by determining the oxygen uptake (VO2) at the ventilatory anaerobic threshold (VAT) and oxygen uptake efficiency slope (OUES). OUES values were compared with two sets of normative values. RESULTS All feasibility criteria were met as 14 representative participants were recruited (recruitment rate: 60.9%), and all participants were able to perform the test and reached the VAT. No adverse events occurred, and all participants were positive toward submaximal CPET. The median VO2 at the VAT was 12.8 mL/kg/min (IQR 11.3-13.6). The median OUES/kg was 23.1 (IQR 20.2-28.9), 106.4% and 109.4% of predicted. CONCLUSION Submaximal CPET using cycle ergometry seems feasible in patients with knee OA scheduled for TKA surgery to evaluate preoperative aerobic capacity.

Abstract
Background There is limited knowledge regarding physical activity and clinical correlates among people who have suffered a pulmonary embolism (PE). Objectives To assess physical activity levels after PE and potential clinical correlates. Methods One hundred forty-five individuals free of major comorbidities were recruited at a mean of 23 months (range, 6-72) after PE diagnosis. Physical activity was assessed by steps/day on the Sensewear monitor for 7 consecutive days, exercise capacity with the incremental shuttle walk test, and cardiac function with left ventricular ejection fraction (LVEF). The association between physical activity and other variables was analyzed by a mixed-effects model. Results Participants achieved a mean of 6494 (SD, 3294; range, 1147-18.486) steps/day. The mixed-effects model showed that physical activity was significantly associated with exercise capacity (β-coefficient, 0.04; 95% CI, 0.03-0.05) and LVEF (β-coefficient, -0.81; 95% CI, -1.42 to -0.21). The analysis further showed that men became less physically active with increasing age (β-coefficient, -0.14; 95% CI, -0.24 to -0.04), whereas no change with age could be detected for women. Conclusion In selected post-PE patients, physical activity seems to be associated with exercise capacity and LVEF but not with quality of life, dyspnea, or characteristics of the initial PE. Men appear to become less physically active with increasing age.

Abstract
OBJECTIVE This study aimed to measure the functional exercise capacity of patients with ankylosing spondylitis (AS) with the incremental shuttle walk test (ISWT), and to determine the factors associated with this test. METHODS This cross-sectional study included 54 patients with AS (29 males, 25 females). The ISWT was performed to determine functional exercise capacity. The number of completed shuttles was recorded, and the total incremental shuttle walk distance (ISWD) was calculated. Disease activity was assessed with the Bath AS Disease Activity Index (BASDAI), physical functioning was assessed with the Bath AS Functional Index (BASFI), and spinal mobility was assessed with the Bath AS Mobility Index (BASMI). Upper body and core endurance were assessed by sit-up and push-up tests. Tests were performed in a single session in the order listed. RESULTS The mean ISWD of the patients was 462.41 ± 97.96 m, and the subjects reached 50.48% of the predicted ISWD. The ISWD of male subjects was significantly higher than that of females (p < .05). At the end of the test, male subjects reached 60.87% of the age-predicted maximal heart rate, and female subjects reached 55.25%. There was a significant positive moderate correlation between ISWD and height (r = 0.535, p < .01), sit-up test (r = 0.617, p < .01), and push-up test (r = 0.495, p < .01), while there was a negative weak correlation between BASFI (r = -0.344, p = .011) and BASMI (r = -0.280, p = .040). CONCLUSION The study showed that functional exercise capacity as assessed by the ISWT decreased in patients with AS. ISWT performance was associated with sex, height, functionality, spinal mobility, and muscular endurance.

Abstract
BACKGROUND Muscle loss is prevalent in chronic obstructive pulmonary disease (COPD). Prior studies evaluating musculoskeletal dysfunction in COPD have focused on individuals with baseline low muscle mass. Currently, there is limited data evaluating clinical characteristics and outcomes associated with progression to incident low muscle mass in a tobacco-exposed cohort of individuals with baseline normal muscle mass. METHODS We evaluated 246 participants from a single-center longitudinal tobacco-exposed cohort with serial spirometry, thoracic imaging, dual energy x-ray absorptiometry (DXA) measurements, walk testing, and plasma adipokine measurements. DXA-derived fat free mass index (FFMI) and appendicular skeletal mass index (ASMI) were used as surrogates for muscle mass. Participants with incident low muscle mass (LM) at follow-up were characterized by FFMI < 18.4 kg/m2 in males and < 15.4 kg/m2 in females and/or ASMI < 7.25 kg/m2 in males and < 5.67 kg/m2 in females. RESULTS Twenty-five (10%) participants progressed to incident low muscle mass at follow-up. At baseline, the LM subgroup had greater active smoking prevalence (60% v. 38%, p = 0.04), lower FFMI (17.8 ± 1.7 kg/m2 v. 19.7 ± 2.9 kg/m2, p = 0.002), lower ASMI (7.3 ± 0.9 kg/m2 v. 8.2 ± 1.2 kg/m2, p = 0.0003), and lower plasma leptin (14.9 ± 10.1 ng/mL v. 24.0 ± 20.9 ng/mL, p = 0.04). At follow-up, the LM subgroup had higher COPD prevalence (68% v. 43%, p = 0.02), lower FEV1/FVC (0.63 ± 0.12 v. 0.69 ± 0.12, p = 0.02), lower %DLco (66.5 ± 15.9% v. 73.9 ± 16.8%, p = 0.03), and higher annual rate of FFMI decline (-0.17 kg/m2/year v. -0.04 kg/m2/year, p = 0.006). There were no differences in age, gender distribution, pack years smoking history, or walk distance. CONCLUSIONS We identified a subgroup of tobacco-exposed individuals with normal baseline muscle mass who progressed to incident DXA-derived low muscle mass. This subgroup demonstrated synchronous lung disease and persistently low circulating leptin levels. Our study suggests the importance of assessing for muscle loss in conjunction with lung function decline when evaluating individuals with tobacco exposure.

Abstract
BACKGROUND The validated Incremental Shuttle Walk Test (ISWT) is widely used for evaluating maximal exercise capacity, with the distance-walked (IWSD) as the primary outcome. However, there are no normative reference values (NRV) and reference equations to predict ISWD for the Singaporean population. OBJECTIVES This study aims to establish the NRV and reference equations for ISWD in healthy Singaporeans aged 21 to 80 and investigate the determining variables during ISWT. METHODS This cross-sectional study recruited community-dwelling healthy subjects aged 21-80 from the community via convenience sampling. Each subject completed two trials of the ISWT according to the standard protocol. Variables measured during the trials included ISWD, pre-and post-test heart rate (HR), oxygen saturation, blood pressure (BP), modified Borg's dyspnoea score and Borg's rate of perceived exertion (RPE). RESULTS 199 healthy Singaporean (females = 114, males = 85) participated in the study. The overall median ISWD was 660.0 metres (m) [interquartile range (IQR):440.0-850.0]. The age-stratified mean ISWD ranged from 430.0 m (IQR:350.0-450.0) (aged 60-80) to 480.0 m (IQR:438.0-650.0) (aged 40-59) to 780.0 m (IQR:670.0-960.0) (aged 21-39). Gender, age, weight, height and HR change (highest post-test HR minus pre-test HR) were the most significant variables (p < 0.001). IWSD (m) = 651.4(Height, m) +89.7(Gender, male = 1; female = 0) -6.31(Age, years) -3.61(Weight, kilograms) +2.54(HR change, beats per minute); R2 = 0.741. Previously published ISWT reference equations cannot accurately predict the ISWD in the Singaporean population. CONCLUSIONS This study investigated the ISWD NRV and established reference equations for healthy Singaporeans aged 21-80. The information would be beneficial in setting performance benchmarks to guide physical assessment, intervention and rehabilitation.

Investigation of Factors Affecting Shuttle Walking Performance at Increased Speed for Patients with Chronic Obstructive Pulmonary Disease. J Clin Med 2023; 12:4752. [PMID: 37510866 PMCID: PMC10381562 DOI: 10.3390/jcm12144752] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 07/12/2023] [Accepted: 07/16/2023] [Indexed: 07/30/2023] Open
Abstract
The aim of this study was to examine the factors affecting the shuttle walking test (SWT) in patients with chronic obstructive pulmonary disease (COPD). A total of 29 patients with COPD (the COPD group) and a healthy group (HG) of 34 women aged between 55 and 74 years were included in the study. After the pulmonary function profiles of the participants were assessed, and the SWT was performed. Walking distances, walking speeds, and SWT levels (SWT-L) were determined with the SWT. Before and after the SWT, the heart rate (HR), oxygen saturation level (SPO2), and Borg scale (perceived exertion (BSe) and dyspnea (BSd)) results were analyzed with a paired sample t-test. The dyspnea levels during activity of daily living were determined with the Medical Research Council (MRC) dyspnea scale, and the relationship between MRC dyspnea (MRCD) and walking distance, speed, and SWT-L was tested using multiple linear regression and Pearson correlation analysis. The walking distance, speed, and SWT-L were lower in the COPD group (p < 0.001) than in the HG. The HR values before and after the SWT changed significantly in the COPD group and the HG (p< 0.001), and the effect size was higher in the COPD group. Although the BSe and BSd results before and after the SWT in the COPD group increased significantly (p < 0.001), they did not change in the HG. There was a highly negative correlation between MRCD and walking distance, speed, and SWT-L in the COPD group (p = 0.002, p = 0.000, and p = 0.001, respectively), but no correlation was found in the HG. The results showed that the HR, perceived exertion, and dyspnea levels of women with COPD whose respiratory functions were lower than the HG were significantly affected on the SWT.

Objective assessment of functional capacity in patients with peripheral artery disease: a narrative review. Expert Rev Cardiovasc Ther 2023; 21:867-875.

Abstract
INTRODUCTION Peripheral artery disease (PAD) patients with claudication symptoms exhibit impaired functional capacity, which has been associated with disease severity, worse quality of life and higher risk of cardiovascular events. Different tests have been used to assess functional capacity in PAD patients. Therefore, understanding the characteristics, strengths and limitations of these tests are important to support the choice of tests to be used in clinical practice. AREAS COVERED This review summarizes the main methods to assess functional capacity in PAD patients, discussing their psychometric properties, applications, and limitations. EXPERT OPINION Robust evidence supports the use of treadmill and six-minute walk tests in PAD patients, as their results are associated with clinically meaningful outcomes, adequate psychometric properties and are sensitive to effects of interventions. On the other hand, other functional tests (Shuttle-walk test, outdoor walking capacity test, timed-up and go, four-meter walk test, heel-rise test, short physical performance battery and modified physical performance battery) are related to activities of daily living and do not require sophisticated equipment and can be easily used in clinical practice. However, these other tests still need evidence regarding their clinical relevance, reliability, and ability to detect long-term intervention changes, providing further investigation directions.

Minimal Clinically Important Differences in Inspiratory Muscle Function Variables after a Respiratory Muscle Training Programme in Individuals with Long-Term Post-COVID-19 Symptoms. J Clin Med 2023; 12:jcm12072720. [PMID: 37048804 PMCID: PMC10095020 DOI: 10.3390/jcm12072720] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 03/31/2023] [Accepted: 04/03/2023] [Indexed: 04/14/2023] Open
Abstract
OBJECTIVE To establish the minimal clinically important difference (MCID) for inspiratory muscle strength (MIP) and endurance (IME) in individuals with long-term post-COVID-19 symptoms, as well as to ascertain which of the variables has a greater discriminatory capacity and to compare changes between individuals classified by the MCID. DESIGN Secondary analysis of randomised controlled trial of data from 42 individuals who performed an 8-week intervention of respiratory muscle training programme. RESULTS A change of at least 18 cmH2O and 22.1% of that predicted for MIP and 328.5s for IME represented the MCID. All variables showed acceptable discrimination between individuals who classified as "improved" and those classified as "stable/not improved" (area under the curve ≥0.73). MIP was the variable with the best discriminative ability when expressed as a percentage of prediction (Youden index, 0.67; sensitivity, 76.9%; specificity, 89.7%). Participants classified as "improved" had significantly greater improvements in quality of life and lung function compared with the participants classified as "stable/not improved". CONCLUSION In individuals with long-term post-COVID-19 symptoms, the inspiratory muscle function variables had an acceptable discriminative ability to assess the efficacy of a respiratory muscle training programme. MIP was the variable with the best discriminative ability, showing better overall performance when expressed as a percentage of prediction.

Feasibility of Seated Stepping and Handshaking as a Cardiopulmonary Exercise Testing: A Pilot Study. J Clin Med 2023; 12:jcm12062140. [PMID: 36983144 PMCID: PMC10057871 DOI: 10.3390/jcm12062140] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 03/06/2023] [Accepted: 03/08/2023] [Indexed: 03/11/2023] Open
Abstract
Cardiopulmonary function is usually assessed by cardiopulmonary exercise testing (CPX) using a cycle ergometer (CE-CPX) or a treadmill, which is difficult in patients with lower extremity motor dysfunction. A stepping and handshaking (SHS) exercise has been developed that can be performed safely and easily while sitting on a chair. This study compared peak oxygen uptake (peak V.O2) between CE-CPX and SHS-CPX in healthy adults and investigated the safety and validity of SHS-CPX. Twenty young adults (mean age 27.8 ± 4.4 years) were randomly assigned to perform CE-CPX or SHS-CPX, with the other test to follow 1–2 weeks later. The peak V.O2, respiratory exchange ratio (RER), peak heart rate, blood pressure, and test completion time were compared between CE-CPX and SHS-CPX. All subjects completed the examination and met the criteria for peak V.O2. SHS-CPX and CE-CPX showed a strong correlation with peak V.O2 (r = 0.85, p < 0.0001). The peak V.O2 (40.4 ± 11.3 mL/min/kg vs. 28.9 ± 8.0 mL/min/kg), peak heart rate (190.6 ± 8.9 bpm vs. 172.1 ± 12.6 bpm), and test completion time (1052.8 ± 143.7 s vs. 609.1 ± 96.2 s) were significantly lower in the SHS-CPX (p < 0.0001). There were no adverse events. The peak V.O2 with SHS-CPX was equivalent to about 70% of that with CE-CPX despite the exercise being performed in a sitting position, suggesting its suitability as a submaximal exercise test.

Abstract
BACKGROUND Lumbar spinal stenosis (LSS) has a substantial impact on mobility, autonomy, and quality of life. Previous reviews have demonstrated inconsistent results and/or have not delineated between specific nonsurgical interventions. OBJECTIVE The purpose of this systematic review is to assess the effectiveness of interventions in the management of LSS. METHODS Eligible studies were randomized controlled trials (RCTs) or prospective studies, included patients with LSS, assessed the effectiveness of any interventions (rehabilitation, surgical, injection, medication), included at least two intervention groups, and included at least one measure of pain, disability, ambulation assessment, or LSS-specific symptoms. Eighty-five articles met inclusion criteria. Meta-analyses were conducted across outcomes. Effect sizes were calculated using Hedge's g and reported descriptively. Formal grading of evidence was conducted. RESULTS Meta-analysis comparing rehabilitation to no treatment/placebo demonstrated significant effects on pain favoring rehabilitation (mean difference, MD -1.63; 95% CI: -2.68, -0.57; I2 = 71%; p = .002). All other comparisons to no treatment/placebo revealed nonsignificant findings. The level of evidence ranged from very low to high for rehabilitation and medication versus no treatment/placebo for pain, disability, ambulation ability, and LSS symptoms. CONCLUSIONS Although the findings of this review are inconclusive regarding superiority of interventions, this accentuates the value of multimodal patient-centered care in the management of patients with LSS.

Clinical characteristics with inflammation profiling of long COVID and association with 1-year recovery following hospitalisation in the UK: a prospective observational study. THE LANCET. RESPIRATORY MEDICINE 2022; 10:761-775. [PMID: 35472304 PMCID: PMC9034855 DOI: 10.1016/s2213-2600(22)00127-8] [Citation(s) in RCA: 173] [Impact Index Per Article: 86.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 03/23/2022] [Accepted: 03/31/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND No effective pharmacological or non-pharmacological interventions exist for patients with long COVID. We aimed to describe recovery 1 year after hospital discharge for COVID-19, identify factors associated with patient-perceived recovery, and identify potential therapeutic targets by describing the underlying inflammatory profiles of the previously described recovery clusters at 5 months after hospital discharge. METHODS The Post-hospitalisation COVID-19 study (PHOSP-COVID) is a prospective, longitudinal cohort study recruiting adults (aged ≥18 years) discharged from hospital with COVID-19 across the UK. Recovery was assessed using patient-reported outcome measures, physical performance, and organ function at 5 months and 1 year after hospital discharge, and stratified by both patient-perceived recovery and recovery cluster. Hierarchical logistic regression modelling was performed for patient-perceived recovery at 1 year. Cluster analysis was done using the clustering large applications k-medoids approach using clinical outcomes at 5 months. Inflammatory protein profiling was analysed from plasma at the 5-month visit. This study is registered on the ISRCTN Registry, ISRCTN10980107, and recruitment is ongoing. FINDINGS 2320 participants discharged from hospital between March 7, 2020, and April 18, 2021, were assessed at 5 months after discharge and 807 (32·7%) participants completed both the 5-month and 1-year visits. 279 (35·6%) of these 807 patients were women and 505 (64·4%) were men, with a mean age of 58·7 (SD 12·5) years, and 224 (27·8%) had received invasive mechanical ventilation (WHO class 7-9). The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804). Factors associated with being less likely to report full recovery at 1 year were female sex (odds ratio 0·68 [95% CI 0·46-0·99]), obesity (0·50 [0·34-0·74]) and invasive mechanical ventilation (0·42 [0·23-0·76]). Cluster analysis (n=1636) corroborated the previously reported four clusters: very severe, severe, moderate with cognitive impairment, and mild, relating to the severity of physical health, mental health, and cognitive impairment at 5 months. We found increased inflammatory mediators of tissue damage and repair in both the very severe and the moderate with cognitive impairment clusters compared with the mild cluster, including IL-6 concentration, which was increased in both comparisons (n=626 participants). We found a substantial deficit in median EQ-5D-5L utility index from before COVID-19 (retrospective assessment; 0·88 [IQR 0·74-1·00]), at 5 months (0·74 [0·64-0·88]) to 1 year (0·75 [0·62-0·88]), with minimal improvements across all outcome measures at 1 year after discharge in the whole cohort and within each of the four clusters. INTERPRETATION The sequelae of a hospital admission with COVID-19 were substantial 1 year after discharge across a range of health domains, with the minority in our cohort feeling fully recovered. Patient-perceived health-related quality of life was reduced at 1 year compared with before hospital admission. Systematic inflammation and obesity are potential treatable traits that warrant further investigation in clinical trials.

Correlation Comparison and Personalized Utility of Field Walking Tests in Assessing the Exercise Capacity of Patients with Chronic Obstructive Pulmonary Disease: A Randomized Controlled Trial. J Pers Med 2022; 12:jpm12060901. [PMID: 35743686 PMCID: PMC9224606 DOI: 10.3390/jpm12060901] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2022] [Revised: 05/27/2022] [Accepted: 05/27/2022] [Indexed: 11/16/2022] Open
Abstract
Background: Incremental shuttle walking tests (ISWT) are regarded as valuable alternatives to 6-min walking tests (6MWT) and cardiopulmonary exercise tests (CPET) owing to the maximal and externally paced loading. This study investigated the validity and reliability of ISWT by analyzing the correlation of the distances of two field tests with peak oxygen consumption (VO2) of CPET in patients with COPD. Methods: In this randomized controlled trial, patients with COPD were enrolled from two hospitals. Three assessments were performed for all patients. The ISWT and 6MWT were repeated twice in Hospital 1 to assess reliability. Results: A total of 29 patients were enrolled. The distances of ISWT (0.782, p < 0.001) and 6MWT (0.512, p = 0.005) correlated with peak VO2. The intraclass correlation coefficients of both ISWT (0.988, p < 0.001) and 6MWT (0.959, p < 0.001) was high. Patients with higher peak VO2 walked a longer distance in ISWT than 6MWT (r = 0.590, p < 0.001). Conclusions: The ISWT more highly correlates with peak VO2 than the 6MWT and has excellent reliability in patients with COPD. According to peak VO2, the walking distances of each field test varied, suggesting that the application should be personalized for the exercise capacity.

Abstract
Background/Aims Low functional capacity has been recognised to be the most important predictor of overall mortality compared to all other cardiovascular risk factors in patients with cardiovascular disease. Walk tests, such as the incremental shuttle walking test and the 6-Minute Walk Test, are used to assess functional capacity in patients, the effectiveness of a cardiac rehabilitation programme and the prognosis of cardiovascular diseases. The aim of this review was to provide a narrative review of the literature and identify the key features of the incremental shuttle walking test as a measure of functional capacity testing in cardiac rehabilitation patients. Methods The PubMed, MEDLINE, Elsevier and Google Scholar databases were searched for relevant scientific articles published up to March 2021 with no restriction on start day. The key words defined by researchers were ‘incremental shuttle walking test’, ‘exercise test’, ‘functional capacity’, ‘cardiovascular disease’, ‘cardiac rehabilitation’, ‘reliability’ ‘prediction; ‘walk tests’. A final set of 31 articles was included in this narrative review. Results Evidence-based findings suggest that the incremental shuttle walking test is a valid, reliable, sensitive, useful tool for detecting and predict cardiorespiratory capacity. Conclusions Clinicians can be confident that they can use the incremental shuttle walking test to monitor changes in functional capacity in patients with cardiovascular disease.

Stronger correlation of peak oxygen uptake with distance of incremental shuttle walk test than 6-min walk test in patients with COPD: a systematic review and meta-analysis. BMC Pulm Med 2022; 22:102. [PMID: 35331171 PMCID: PMC8953060 DOI: 10.1186/s12890-022-01897-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2021] [Accepted: 03/17/2022] [Indexed: 11/17/2022] Open
Abstract
Background The 6-min walk test (6MWT) and incremental shuttle walk test (ISWT) are valid and reliable measures to assess exercise capacity of patients with chronic obstructive pulmonary disease (COPD). However, the comparison of correlation between peak oxygen uptake (peak VO2) and 6MWT or ISWT distance has not been investigated. We aimed to investigate the correlation between peak VO2 and 6MWT and ISWT distances in COPD patients through a meta-analysis. Methods We systematically searched MEDLINE, Scopus, Embase, and the Cochrane Library up to June, 2020 for studies comparing the correlation of peak VO2 with either 6MWT or ISWT in COPD patients. Meta-analysis was performed with R software using a fixed-effect model. We compared the correlation coefficient and measured the heterogeneity using I2 statistics. Results We identified 12 studies involving 746 patients. Meta-analysis showed a significant correlation between peak VO2 and 6MWT and ISWT distances (6MWT: r = 0.65, 95% CI 0.61–0.70; ISWT: r = 0.81, 95% CI 0.74–0.85; p < 0.0001). The heterogeneity was lower in ISWT than in 6MWT (6MWT: I2 = 56%, p = 0.02; ISWT: I2 = 0%, p = 0.71). Subgroup analysis showed a higher correlation coefficient in the low exercise capacity group than in the high exercise capacity group in both field tests. Conclusions 6MWT and ISWT significantly correlated with peak VO2. Our findings suggest that ISWT has a stronger correlation with peak VO2 than 6MWT. The exercise capacity in COPD patients may affect the strength of the relationship between peak VO2 and walking distance in both field tests, suggesting the importance of using various exercise tests.

Title: Assessment of VO 2peak and Exercise Capacity after Stroke: a Validity Study of the Human Activity Profile Questionnaire. Arch Phys Med Rehabil 2022; 103:1771-1776. [PMID: 35101389 DOI: 10.1016/j.apmr.2022.01.141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 11/18/2021] [Accepted: 01/02/2022] [Indexed: 11/02/2022]
Abstract
OBJECTIVE to investigate, in individuals after stroke, the concurrent validity of the Human Activity Profile (HAP) to provide the VO2peak and the construct validity of the HAP to assess exercise capacity; and to provide equations based upon the HAP outcomes to estimate the distance covered in the Incremental Shuttle Walking Test (ISWT). DESIGN Cross-sectional study. SETTING University laboratory. PARTICIPANTS Fifty-seven individuals (54±11 years) after stroke. INTERVENTION Not applicable. MAIN OUTCOME MEASURES Agreement between the VO2peak provided by the HAP (lifestyle energy consumption (LEC) outcome, in mL.kg-1.min-1) and the gold standard measure of the VO2peak (mL.kg-1.min-1), obtained through the symptom-limited Cardiopulmonary Exercise Test (CPET). Correlation between the HAP outcomes (LEC; the maximum activity score (MAS) and the adjusted activity score (AAS)) and the construct measure: the distance covered (in meters) in the ISWT. An equation to estimate the distance covered in the ISWT was determined. RESULTS High magnitude agreement was found between the VO2peak, in mL.kg-1.min-1, obtained by the symptom-limited CPET and the value of VO2peak, in mL.kg-1.min-1, provided by the HAP (LEC) (ICC=0.75;p<0.001). Low to moderate magnitude correlations were found between the distance covered in the ISWT and the HAP (LEC/MAS/AAS) (0.34≤rho≤0.58). The equation to estimate the distance covered in the ISWT explained 31% of the variability of the ISWT (ISWTestimated=-361.91+(9.646xAAS)). CONCLUSION The HAP questionnaire is a clinically applicable way to provide a valid value of VO2peak (in mL.kg-1.min-1) and to assess the exercise capacity of individuals after stroke. Furthermore, an equation to estimate the distance covered in the submaximal field exercise test (ISWT) based on the result of the AAS (in points) was provided.

Abstract
Background Persistent dyspnea is a common symptom after pulmonary embolism (PE). However, the pathophysiology of persistent dyspnea is not fully clarified. This study aimed to explore possible associations between diffuse myocardial fibrosis, as assessed by cardiac magnetic resonance (CMR) T1 mapping, and persistent dyspnea in patients with a history of PE. Methods CMR with T1 mapping and extracellular volume fraction (ECV) calculations were performed after PE in 51 patients with persistent dyspnea and in 50 non-dyspneic patients. Patients with known pulmonary disease, heart disease and CTEPH were excluded. Results Native T1 was higher in the interventricular septum in dyspneic patients compared to non-dyspneic patients; difference 13 ms (95% CI: 2–23 ms). ECV was also significantly higher in patients with dyspnea; difference 0.9 percent points (95% CI: 0.04–1.8 pp). There was no difference in native T1 or ECV in the left ventricular lateral wall. Native T1 in the interventricular septum had an adjusted Odds Ratio of 1.18 per 10 ms increase (95% CI: 0.99–1.42) in predicting dyspnea, and an adjusted Odds Ratio of 1.47 per 10 ms increase (95% CI: 1.10–1.96) in predicting Incremental Shuttle Walk Test (ISWT) score < 1020 m. Conclusion Septal native T1 and ECV values were higher in patients with dyspnea after PE compared with those who were fully recovered suggesting a possible pathological role of myocardial fibrosis in the development of dyspnea after PE. Further studies are needed to validate our findings and to explore their pathophysiological role and clinical significance.

Is the modified shuttle test a maximal effort test in children and adolescents with asthma? Pediatr Pulmonol 2022; 57:75-80. [PMID: 34569722 DOI: 10.1002/ppul.25706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2021] [Revised: 08/12/2021] [Accepted: 09/15/2021] [Indexed: 11/11/2022]
Abstract
PURPOSE Whether the modified shuttle test (MST) achieves maximal effort in children and adolescents with asthma is unclear. The aim was to compare the physiological responses of MST to the cardiopulmonary exercise test (CPET) in pediatric patients with asthma, to observe its convergent validity. PATIENTS AND METHODS A cross-sectional study with volunteers with asthma (6-17 years of age) under regular treatment. The MST is an external-paced test, and the participants were allowed to walk/run. CPET was performed on a cycle ergometer to compare with MST. Gas exchange (VO2 , VCO2 , and VE) and heart rate (HR) were the outcomes and were continuously assessed in both tests. RESULTS Forty-seven volunteers were included, normal lung function expiratory forced volume at 1st second/forced vital capacity (FEV1 /FVC) 88.6 (7.7). VO2peak was higher at MST (2.0 ± 0.6 L/min) compared to CPET (1.6 ± 0.5 L/min), p < 0.001. Similar results was observed to VE at MST (50 ± 16 L/min) versus VE at CPET (40 ± 13 L/min), and to VCO2 at MST (2.1 ± 0.8 L/min) versus VCO2 at CPET (1.7 ± 0.6 L/min), p < 0.001. HR was also higher at MST (94 ± 6%pred) versus CPET (87 ± 8%pred), p = 0.002. VO2peak in MST correlated to the CPET (r = 0.78, p < 0.001). The ICC of VO2peak between tests was 0.73 (0.06-0.89), p < 0.001, and VO2peak Bland-Altman analysis showed a bias of 0.46 L/min. CONCLUSION The MST showed a maximal physiologic response in children and adolescents with asthma. It is a valid test and can be used as an alternative to evaluating exercise capacity.

In-hospital pulmonary rehabilitation after completion of primary respiratory disease treatment improves physical activity and ADL performance: A prospective intervention study. Medicine (Baltimore) 2021; 100:e28151.

Abstract
INTRODUCTION Pulmonary rehabilitation improves the physical condition of patients with chronic respiratory disease; however, there are patients who cannot leave the hospital because of their low activities of daily living (ADLs), despite the completion of primary respiratory disease treatment and rehabilitation during treatment. Therefore, this study demonstrated that those patients recovered their ADLs through in-hospital pulmonary rehabilitation after treatment completion. METHODS We prospectively studied 24 hospitalized patients who had some remaining symptoms and showed low ADL scores of 9 points or less on the short physical performance battery after undergoing treatment for respiratory disease in Fukujuji Hospital from October 2018 to October 2019, excluding 2 patients who had re-exacerbation and 1 patient who could not be examined using the incremental shuttle walk test (ISWT). After completion of the primary respiratory disease treatment, patients moved to the regional comprehensive care ward, and they received pulmonary rehabilitation for 2 weeks. In the ward, patients who could not yet leave the hospital could undergo pulmonary rehabilitation for up to 60 days. Data were evaluated three times: upon treatment completion (baseline), postrehabilitation, and 3 months after baseline. The main outcome was an improvement in the incremental shuttle walk test (ISWT) postrehabilitation. RESULTS The median age of the patients was 80 (interquartile range (IQR): 74.8-84.5), and 14 patients (58.3%) were male. The ISWT distance significantly increased postrehabilitation (median [IQR]: 60 m [18-133] vs 120 m [68-203], P < .001). The Barthel Index (BI) (P < .001), the modified Medical Research Council (P < .001), and other scale scores were also improved. Among patients with acute respiratory diseases such as pneumonia, chronic obstructive pulmonary disease, and interstitial pneumonia, ISWT and other data showed improvement at the postrehabilitation timepoint. Ten patients who could perform examinations at 3 months after baseline were evaluated 3 months after taking baseline data prior to starting rehabilitation. The ISWT showed significant improvement 3 months after baseline compared to baseline (P = .024), and the ISWT distance was maintained after rehabilitation. DISCUSSION AND CONCLUSIONS Physical activity, symptoms, mental health, and ADL status in patients who had not recovered after primary treatment completion for respiratory diseases could improve through in-hospital pulmonary rehabilitation.

Abstract
Rationale: Exercise capacity predicts mortality in pulmonary arterial hypertension (PAH), but limited data exist on the routine use of maximal exercise testing. Objectives: This study evaluates a simple-to-perform maximal test (the incremental shuttle walking test) and its use in risk stratification in PAH. Methods: Consecutive patients with pulmonary hypertension were identified from the ASPIRE (Assessing the Spectrum of Pulmonary hypertension Identified at a REferral centre) registry (2001–2018). Thresholds for levels of risk were identified at baseline and tested at follow-up, and their incorporation into current risk stratification approaches was assessed. Results: Of 4,524 treatment-naive patients with pulmonary hypertension who underwent maximal exercise testing, 1,847 patients had PAH. A stepwise reduction in 1-year mortality was seen between levels 1 (≤30 m; 32% mortality) and 7 (340–420 m; 1% mortality) with no mortality for levels 8–12 (≥430 m) in idiopathic and connective tissue disease–related PAH. Thresholds derived at baseline of ≤180 m (>10%; high risk), 190–330 m (5–10%; intermediate risk), and ≥340 m (<5%; low risk of 1-yr mortality) were applied at follow-up and also accurately identified levels of risk. Thresholds were incorporated into the REVEAL (Registry to Evaluate Early and Long-Term Pulmonary Arterial Hypertension Disease Management) 2.0 risk score calculator and French low-risk approach to risk stratification, and distinct categories of risk remained. Conclusions: We have demonstrated that maximal exercise testing in PAH stratifies mortality risk at baseline and follow-up. This study highlights the potential value of the incremental shuttle walking test as an alternative to the 6-minute walking test, combining some of the advantages of maximal exercise testing and maintaining the simplicity of a simple-to-perform field test.

Abstract
OBJECTIVE To determine the accuracy of incremental Shuttle Walking Test (ISWT) in detecting exercise-induced bronchospasm (EIB) in adults with asthma and to verify whether there is an association of the drop in FEV1 between ISWT and cardiopulmonary exercise testing with constant-load CPET-CL. METHODS In this cross-sectional study 32 individuals with asthma performed two ISWTs, an incremental cardiopulmonary exercise test (CPET-I) and a constant-load cardiopulmonary exercise test (CPET-CL) with na interval of 48 h between tests. Spirometric measurements were obtained 5, 10, 15, 20 and 30 min after exercise; an FEV1 decline > 10% was considered EIB. RESULTS Fifteen individuals had EIB in both tests [χ2 = 9.41; κ = 0.46 p < 0.002 (95% CI: 0.201-0.708)], with moderate agreement. There was a significant correlation between the greatest variation in the drop in FEV1 between the ISWT and the CPET-CL (r = 0.48; p < 0.01). There was a significant difference for ventilation maintenance time above 40% of Maximum Voluntary Ventilation between the groups of positive EIB (p = 0.001) and negative EIB (p = 0.001) and for ventilatory demand (positive EIB group) (p = 0.008) between ISWT vs CPET-CL. Moreover, assuming CPET-CL as the criterion test, ISWT presented a sensitivity of 62.5% and specificity was 100%. CONCLUSION ISWT showed moderate accuracy in detecting EIB in adults with asthma and was able to show similar metabolic and ventilatory demand presented in CPET-CL.

Abstract
Increasing evidence supports that individualised exercise is safe and beneficial for adults treated with allogeneic bone marrow transplantation (alloBMT), although this is not part of standard care and no research has investigated group-based interventions. This study aimed to determine safety, feasibility and exploratory effects of a supervised group-based inpatient and subsequent home-based exercise programme in alloBMT. This single-site prospective cohort study included consecutive adults treated with alloBMT for haematological disease. All participants received usual care in addition to the protocolised exercise programme pre-transplant until 60 days post transplant. The primary outcome was feasibility; secondary outcomes included exercise capacity, frailty, health-related quality of life and strength. Consent rate was 100% (n = 42); 83% (n = 35) completed all aspects of the intervention and outcome testing; of those, 83% (n = 29) attended ≥2 group-exercise sessions per week; no adverse events occurred. Emotional well-being significantly improved over time, which may highlight benefits of group-based intervention. Other outcomes significantly declined from pre-BMT to hospital discharge, with some improvement at 60 days post-BMT. Participants with early signs of frailty demonstrated the greatest decline in outcomes. Group-based exercise was safe and feasible; observations from this study highlight the importance of baseline identification of frailty to target intervention at those who need it most.

Pediatr Pulmonol 2021; 56:1550-1557. [PMID: 33650810 DOI: 10.1002/ppul.25348] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Revised: 02/22/2021] [Accepted: 02/24/2021] [Indexed: 11/11/2022]
Abstract
OBJECTIVE To evaluate the reproducibility of the modified shuttle test (MST) and to determine whether the test needs to be performed more than once to assess the exercise capacity of children and adolescents with cystic fibrosis (CF). METHODS This was a longitudinal study including patients diagnosed with CF aged more than 6 years. The participants were followed for a period of 9 months and were evaluated at three different time points (visits 1, 2, and 3). Spirometric, anthropometric, clinical, and genetic data were collected, and two MSTs were performed at each visit. RESULTS Forty-eight clinically stable volunteers with a mean age of 10.1 ± 2.7 years were initially included. The reproducibility of the test was evaluated using the distance achieved (DA) as the main variable. There were no significant differences in the DA (visit 1, p = .23; visit 2, p = .24; visit 3, p = .85), baseline heart rate (HR) (visit 1, p = .35; visit 2, p = .20; visit 3, p = .98), and peak HR (visit 1, p = .16; visit 2, p = .94; visit 3, p = .23) between the tests performed at each visit. The test-retest reliability demonstrated a high intraclass correlation coefficient at all visits (visit 1, 2, and 3: 0.83, 0.90, and 0.80, respectively) and the variation in HR was the main factor associated with the DA in the MST over time. CONCLUSION The MST was found to be a reproducible and reliable test. The data presented here support the use of a single MST to evaluate and monitor exercise capacity of patients with CF during clinic visits.

Adapted Chester Step Test Can Have Maximal Response Characteristics for the Assessment of Exercise Capacity in Young Women. Healthcare (Basel) 2021; 9:healthcare9030308. [PMID: 33802097 PMCID: PMC8000948 DOI: 10.3390/healthcare9030308] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2021] [Revised: 03/03/2021] [Accepted: 03/07/2021] [Indexed: 11/17/2022] Open
Abstract
Chester step test (CST) estimates the exercise capacity through a submaximal response, which can limit its application in the prescription of exercise. This study aimed to assess whether an adaptation of the CST (with a progressive profile) can have maximal response characteristics in young women and compare it to the incremental shuttle walk test (ISWT). Another aim was to determine its within-day test–retest reliability. A cross-sectional study was conducted with 25 women (20.3 ± 1.5 years) who performed the field tests twice on two different days (48 h apart). The maximal effort attainment was assessed by the heart rate (HR), perception of exertion (Borg scale), and blood lactate concentration. For the performance variables, Pearson’s correlation and intraclass correlation coefficient (ICC2,1) were used. In the best test, mean values of maximal response were observed in the adapted CST (94.0 ± 6.5% of age-predicted HRmax, 11.3 ± 4.5 mmol/dl of blood lactate, and 18.4 ± 1.5 of Borg rating). The correlations between the adapted CST and the ISWT were weak to moderate (0.38 ≤ r ≤ 0.55; p < 0.05). Fair to good reliability was found for the adapted CST (ICC2,1 = 0.48–0.61). The adapted CST showed mean values of maximal response, weak to moderate association with the ISWT, and low within-day test–retest reliability in young women.

Abstract
RESUMO O objetivo deste estudo foi avaliar a validade externa de três equações de referência para o cálculo da distância a ser percorrida no incremental shuttle walking test (ISWT) por idosos comunitários, e, por fim, identificar qual equação prediz melhor a distância nessa faixa etária. Foram selecionados 84 idosos cadastrados nas Unidades Básicas de Saúde de Diamantina, Minas Gerais. Os voluntários foram submetidos ao ISWT e a distância percorrida em metros até a interrupção do teste foi registrada e utilizada para comparação com as equações de predição. Os voluntários apresentaram média de idade de 73,15±5,89 anos e alguns comprometimentos de saúde comuns dessa faixa etária, sendo a maioria mulheres e praticantes de atividade física. A análise estatística demonstrou que houve interação entre os fatores, ou seja, existe diferença entre as distâncias obtidas pelo ISWT e as distâncias obtidas pelas equações. Houve diferença também nas comparações entre os sexos (p<0,05) e a Equação 1 apresentou maior força de correlação (p<0,0001; r=0,414) com a distância real percorrida em relação às outras equações. Portanto, este estudo demonstrou uma diferença na comparação das distâncias real e calculadas por três equações de predição do ISWT, sugerindo que as equações utilizadas podem superestimar a distância percorrida pelos idosos, e que entre essas a Equação 1 apresentou uma predição mais próxima da distância percorrida para a amostra de idosos avaliada.

Abstract
OBJECTIVE The purpose of this study was to evaluate the intrarater and interrater reliability of the 2-minute step test (2MST) in active and sedentary lean adults and to identify the test cutoff point to differentiate active from sedentary individuals. METHODS This observational study involved 4 mixed-sex groups (each with 50 lean participants): group 1, sedentary and aged 18 to 24 years; group 2, active and aged 18 to 24 years; group 3, sedentary and aged 25 to 44 years; and group 4, active and aged 25 to 44 years. The 2MST was administered independently by 2 examiners (with 3 months' training) at 2 different times, with a 7-day interval. Habitual physical activity was evaluated by means of the Baecke Questionnaire (BQ). In statistical analysis, the Pearson correlation coefficient was used to verify the correlation between the 2MST and BQ; intraclass correlation coefficients (ICC2,3) were used to determine the intrarater and interrater reliability of the 2MST; and the receiver operating characteristic curve was used to identify the accuracy of the 2MST. RESULTS Excellent intrarater and interrater reliability were found for all 4 groups (intraclass correlation coefficients ≥ 0.83). Correlating the 2MST score with the BQ score, a significant, positive, weak correlation was observed (r = 0.344, P < .001). For differentiating active from sedentary individuals, the 2MST showed low accuracy (area under the curve = 0.671), with 61% sensitivity and 67% specificity. CONCLUSION This study showed that the 2MST is a reliable test with a low amount of inherent error. There was a significant correlation between the 2MST and usual physical activity measured, and slight accuracy in differentiating active from sedentary individuals.

Pulmonary rehabilitation to improve physical capacity, dyspnea, and quality of life following pulmonary embolism (the PeRehab study): study protocol for a two-center randomized controlled trial. Trials 2021; 22:22. [PMID: 33407792 PMCID: PMC7789311 DOI: 10.1186/s13063-020-04940-9] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Accepted: 11/30/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Recently, a large group of patients with persistent dyspnea, poor physical capacity, and reduced health-related quality of life (HRQoL) following pulmonary embolism (PE) has been identified and clustered under the name "post pulmonary embolism syndrome" (PPS). These patients seem good candidates for pulmonary rehabilitation. The aim of the study is to explore whether a pulmonary rehabilitation program can improve physical capacity, dyspnea, and HRQoL in PPS patients. METHODS A two-center randomized controlled trial (RCT) is being performed at Østfold Hospital and Akershus University Hospital in Norway. Patients with PPS are 1:1 randomized into an intervention or a control group. The intervention consists of a supervised, outpatient rehabilitation program twice weekly (1 h) for 8 weeks provided by experienced physiotherapists. The intervention involves individually adapted exercises based on existing pulmonary rehabilitation programs (relaxation, interval, and resistance training), and an educational session including topics such as normal anatomy and physiology of the respiratory and circulatory system, information on PE/PPS, breathing strategies, and benefits of exercise/physical activity. Patients randomized to the control group receive usual care without specific instructions to exercise. Participants in the intervention and control groups will be compared based on assessments conducted at baseline, 12 weeks, and 36 weeks after inclusion using the incremental shuttle walk test (primary outcome) and endurance shuttle walk test (exercise capacity), Sensewear activity monitor (daily physical activity), the modified Medical Research Council scale, the Shortness of Breath Questionnaire (dyspnea), and EQ-5D-5L and the Pulmonary Embolism Quality of Life Questionnaire (HRQoL). Recruitment of 190 patients is currently ongoing. DISCUSSION Results from this study may provide a currently untreated group of PPS patients with an effective treatment resulting in reduced symptoms of dyspnea, improved exercise capacity, and better HRQoL following PE. TRIAL REGISTRATION Clinical Trials NCT03405480 . Registered prospectively on September 2017. Protocol version 1 (from original protocol September 2017). The study protocol has been reported in accordance with the Standard Protocol Items: Recommendations for Clinical Interventional Trials (SPIRIT) guidelines (Additional file 1).

Abstract
BACKGROUND Subjective cognitive decline (SCD) is an early manifestation of Alzheimer's disease (AD) and offers a therapeutic window where interventions have strong potential to prevent or delay the progression of AD. Aerobic exercise and cognitive training represent two promising interventions for AD prevention, but their synergistic effect has yet to be assessed in persons with SCD. METHODS/DESIGN The purpose of this single-blinded, 3-parallel group randomized controlled trial is to test the synergistic efficacy of an exergame intervention (simultaneous moderate-intensity aerobic cycling and cognitive training) on cognition and aerobic fitness in community-dwelling older adults with SCD. The Exergames Study will randomize 96 participants on a 2:1:1 allocation ratio to 3-month exergame, cycling only, or attention control (stretching). Primary outcomes include global cognition and aerobic fitness, which will be assessed at baseline and after 3 months. The specific aims of the Exergames Study are to (1) determine the efficacy of the exergame in older adults with SCD and (2) assess the distraction effect of exergame on aerobic fitness. Data will be analyzed using ANOVA following intention-to-treat. DISCUSSION This study will test the synergistic effects of exergame on cognition and aerobic fitness. It has the potential to advance prevention research for AD by providing effect-size estimates for future trials. TRIAL REGISTRATION ClinicalTrials.gov NCT04311736 . Registered on 17 March 2020.

Abstract
OBJECTIVE To evaluate the efficacy of an inspiratory muscle training protocol on inspiratory muscle function, functional capacity, and quality of life in patients with asthma. DESIGN A single-blind, randomized controlled clinical trial. SETTING Community-based. SUBJECTS Patients with asthma, aged between 20 and 70 years old, non-smokers. INTERVENTIONS Participants were randomized into two groups: inspiratory muscle training group performed inspiratory muscle training 5 days a week for 8 weeks, consisting of six sets of 30 breaths per day with a training load ⩾50% of maximal inspiratory pressure, plus an educational program; the control group only received the educational program. MAIN MEASUREMENTS Maximal inspiratory pressure, inspiratory muscle endurance, and the distance performed on the incremental shuttle walking test were assessed pre-intervention, post-intervention and at follow-up (3 months after the end of the intervention). The asthma quality of life questionnaire was applied pre and post-intervention. RESULTS Data from 39 participants were analyzed. Maximal inspiratory pressure in percentage of predicted and endurance test duration were significantly higher post-intervention in the inspiratory muscle training group (∆ post-pre: 50.8% vs 7.3% of predicted - P < 0.001 and ∆ post-pre: 207.9 seconds vs 2.7 seconds - P < 0.001, respectively). There was no significant difference in the incremental shuttle walking distance between groups (∆ post-pre: 30.9 m vs -8.1 m, P = 0.165). Quality of life was perceived as significantly better, without a difference between groups (P > 0.05). CONCLUSIONS About 8 weeks of inspiratory muscle training in patients with controlled asthma significantly increased inspiratory muscle strength and endurance.

Abstract
The aim of the present clinical trial is to evaluate the effectiveness of neuromuscular versus classical strength-resistance training as part of a cardiac rehabilitation programme in patients following acute coronary syndrome. The study is designed as a double-blinded, randomised, and controlled clinical trial. Thirty participants suffering from acute coronary syndrome who meet our inclusion criteria will be recruited by a private tertiary hospital. The intervention group will follow 20 sessions of a cardiac rehabilitation programme divided into two parts: aerobic training and neuromuscular strength-resistance training. The control group will complete the same aerobic training as well as a classical strength-resistance training workout programme. The primary outcome of the study will be the mean difference in change from baseline in the Incremental Shuttle Walking Test. The secondary outcomes will be the cardiorespiratory fitness of the patients (assessed by means of the Chester Step Test), lower-limb performance (assessed with the 30-Second Chair Stand Test and Single-Leg Squat Test), lower-limb strength (hip flexor handheld dynamometry), sexual dysfunction assessment (Sex Health Inventory for Men) and quality of life (EQ-5D-5L). This work will provide evidence for the effectiveness of a neuromuscular versus a classic strength-training programme in terms of cardiorespiratory fitness, lower-limb performance capacities and quality of life, in cardiac patients. The data obtained could lead to more effective and functional workouts which, in turn, may enhance the speed at which these patients can return to their everyday activities of life and improve the efficiency of their movement patterns and heart responses. Furthermore, patients may find neuromuscular workout routines more motivating and engaging, thus encouraging them to adopt healthier lifestyle patterns.

Abstract
The purpose of this study was to investigate the relationships among peak exercise parameters on 6-min walk test, shuttle walk test, and laboratory-based cardiopulmonary exercise testing in persons with Alzheimer's dementia. This study is a cross-sectional analysis of the baseline data of 90 participants (age 77.1 [6.6] years, 43% female) from the FIT-AD trial. Cardiopulmonary exercise testing produced significantly higher peak heart rate (118.6 [17.5] vs. 106 [22.8] vs. 106 [18.8] beats/min), rating of perceived exertion (16 [2.1] vs. 12 [2.3] vs. 11 [2.1]), and systolic blood pressure (182 [23.7] vs. 156 [18.9] vs. 150 [16.9] mmHg) compared with the shuttle walk test and 6-min walk test, respectively. Peak walking distance on shuttle walk test (241.3 [127.3] m) and 6-min walk test (365.0 [107.9] m) significantly correlated with peak oxygen consumption (17.1 [4.3] ml·kg-1·min-1) on cardiopulmonary exercise testing (r = .449, p ≤ .001 and r = .435, p ≤ .001), respectively, which is considerably lower than what is seen in older adults and persons with cardiopulmonary diseases.

Abstract
OBJECTIVE To investigate the effects of rehabilitation methods on leg muscle function and functional performance in cystic fibrosis. DATA SOURCES A literature search was conducted in PubMed (MEDLINE), Scopus and the Cochrane Library from inception to October 12, 2020. A secondary hand search through reference lists from identified articles was conducted. REVIEW METHODS Three authors independently checked the full-text copies for eligibility of relevant articles. Randomized controlled trials were included. Methodological quality was assessed using the Physiotherapy Evidence Database scale. The PRISMA guidelines were followed. Results suggestive of leg muscle function (e.g. strength, power, endurance, and fatigue) and functional performance were reported. RESULTS The search identified 8 studies (233 patients). The overall quality of these articles was good. Rehabilitation modalities investigated were physical exercises (aerobic, anaerobic and resistance training) (n = 7) and neuromuscular electrical stimulation (n = 1). Most studies (n = 4) reported on the effects of combined aerobic and resistance training and showed improvement on leg strength when exercises were supervised. Aerobic training alone or the use of neuromuscular electrical stimulation also enhanced leg strength, whereas anaerobic training did not. Two studies evaluated leg fatigue and found no improvement compared to standard care. One study assessed the effect of exercises on functional performance and found no improvement when compared to standard care. No studies emphasized the impact of rehabilitation methods on leg muscle endurance or power. CONCLUSION Combined aerobic and resistance training enhances leg muscle strength in cystic fibrosis. There is insufficient data on other leg muscle outcomes, nor on alternative rehabilitation strategies.

Abstract
BACKGROUND There are limitations to perform the cardiopulmonary exercise test (CPET) and the six-minute walking test (6MWT) in clinical settings. The incremental shuttle walking test (ISWT) might be an alternative assessment of exercise capacity and an estimation of cardiopulmonary fitness after stroke. OBJECTIVES To investigate the test-retest and inter-rater reliabilities, the standard error of measurement (SEM) and the minimal detectable change (MDC) of the ISWT, its construct validity to assess exercise capacity and its concurrent validity to estimate cardiopulmonary fitness after stroke. METHODS Prospective diagnostic accuracy study. Fifty-one individuals (54 ± 11 years) at the chronic phase (65 ± 73 months after stroke) were included. The distance walked, in meters, during the 12-stage-ISWT and the 6MWT and the peak oxygen uptake (VO2peak, ml.kg-1.min-1) in the CPET (gold standard) were assessed. RESULTS Significant and high to very high magnitude test-retest and inter-rater reliabilities (0.88≤ICC≤0.93) of the ISWT was found. The SEM for both reliabilities was small (-23.35 m≤ SEM≤41.47 m). The MDC for test-retest and inter-rater reliabilities were 114.63 m and 64.53 m, respectively. For construct validity, a significant and high magnitude correlation between the ISWT and the 6MWT was found (ICC = 0.82). For the concurrent validity, a significant, but low magnitude correlation was found between the ISWT and the VO2peak (rho = 0.42). CONCLUSIONS The ISWT demonstrated adequate reliabilities and construct validity for exercise capacity assessment. However, the concurrent validity of the ISWT as an estimation of cardiopulmonary fitness still requires further research.

Abstract
BACKGROUND Aerobic training and breathing exercises are interventions that improve asthma control. However, the outcomes of these 2 interventions have not been compared. OBJECTIVE To compare the effects of aerobic training versus breathing exercises on clinical control (primary outcome), quality of life, exercise capacity, and airway inflammation in outpatients with moderate-to-severe asthma. METHODS Fifty-four asthmatics were randomized into either the aerobic training group (AG, n = 29) or the breathing exercise group (BG, n = 25). Both interventions lasted for 24 sessions (2/week, 40 minutes/session). Asthma clinical control (Asthma Control Questionnaire [ACQ]), quality of life (Asthma Quality of Life Questionnaire), asthma symptom-free days (ASFD), airway inflammation, exercise capacity, psychological distress (Hospital Anxiety and Depression Scale), daily-life physical activity (DLPA), and pulmonary function were evaluated before, immediately after, and 3 months after the intervention. RESULTS Both interventions presented similar results regarding the ACQ score, psychological distress, ASFD, DLPA, and airway inflammation (P > .05). However, participants in the AG were 2.6 times more likely to experience clinical improvement at the 3-month follow-up than participants in the BG (P = .02). A greater proportion of participants in the AG also presented a reduction in the number of days without rescue medication use compared with BG (34% vs 8%; P = .04). CONCLUSIONS Outpatients with moderate-to-severe asthma who participated in aerobic training or breathing exercise programs presented similar results in asthma control, quality of life, asthma symptoms, psychological distress, physical activity, and airway inflammation. However, a greater proportion of participants in the AG presented improvement in asthma control and reduced use of rescue medication.

Abstract
Background Chronic obstructive pulmonary disease (COPD) is highly prevalent and significantly affects the daily functioning of patients. Self-management strategies, including increasing physical activity, can help people with COPD have better health and a better quality of life. Digital mobile health (mHealth) techniques have the potential to aid the delivery of self-management interventions for COPD. We developed an mHealth intervention (Self-Management supported by Assistive, Rehabilitative, and Telehealth technologies-COPD [SMART-COPD]), delivered via a smartphone app and an activity tracker, to help people with COPD maintain (or increase) physical activity after undertaking pulmonary rehabilitation (PR). Objective This study aimed to determine the feasibility and acceptability of using the SMART-COPD intervention for the self-management of physical activity and to explore the feasibility of conducting a future randomized controlled trial (RCT) to investigate its effectiveness. Methods We conducted a randomized feasibility study. A total of 30 participants with COPD were randomly allocated to receive the SMART-COPD intervention (n=19) or control (n=11). Participants used SMART-COPD throughout PR and for 8 weeks afterward (ie, maintenance) to set physical activity goals and monitor their progress. Questionnaire-based and physical activity–based outcome measures were taken at baseline, the end of PR, and the end of maintenance. Participants, and health care professionals involved in PR delivery, were interviewed about their experiences with the technology. Results Overall, 47% (14/30) of participants withdrew from the study. Difficulty in using the technology was a common reason for withdrawal. Participants who completed the study had better baseline health and more prior experience with digital technology, compared with participants who withdrew. Participants who completed the study were generally positive about the technology and found it easy to use. Some participants felt their health had benefitted from using the technology and that it assisted them in achieving physical activity goals. Activity tracking and self-reporting were both found to be problematic as outcome measures of physical activity for this study. There was dissatisfaction among some control group members regarding their allocation. Conclusions mHealth shows promise in helping people with COPD self-manage their physical activity levels. mHealth interventions for COPD self-management may be more acceptable to people with prior experience of using digital technology and may be more beneficial if used at an earlier stage of COPD. Simplicity and usability were more important for engagement with the SMART-COPD intervention than personalization; therefore, the intervention should be simplified for future use. Future evaluation will require consideration of individual factors and their effect on mHealth efficacy and use; within-subject comparison of step count values; and an opportunity for control group participants to use the intervention if an RCT were to be carried out. Sample size calculations for a future evaluation would need to consider the high dropout rates.

Abstract
OBJECTIVE To compare performance and cardiorespiratory responses in field tests performed by healthy children, with and without the use of a portable gas analyzer (PGA), and to analyze the reproducibility of the tests. METHOD The study included healthy children aged 6 to 14 years old. The sample was divided into children who underwent field tests (modified shuttle walk test [MSWT], 6-minute walk test [6MWT], and ADL-Glittre for pediatrics [TGlittre-P]) without PGA (GS) and children who carried the equipment K4b2 -COSMED, Rome, Italy (GK). RESULTS A total of 120 children participated in the study, 31 in the GK (mean age 10.16 ± 1.81 years old) and 89 in GS (mean age 10.1 ± 1.79 years old). The groups did not differ from each other and there was no significant difference in the performance of the 6MWT and MSWT intergroup (P > .05), but the significant alteration in the variables of the cardiorespiratory response was identified. In the TGlittre-P, the GK completed the test in a shorter time than the GS (2.69 ± 0.38 minutes vs 2.91 ± 0.40 minutes) and both presented alterations in most cardiorespiratory variables. The intragroup reproducibility showed concordance in all tests, and there was no concordance between groups (P > .05). CONCLUSION The use of PGA had a lower time spent on TGlittre-P. In the 6MWT and MSWT, there was no difference in cardiorespiratory performance and response with and without the use of PGA. The three field tests were reproducible, but the same test, with and without the use of PGA, did not show agreement.

Abstract
The purpose of the present study was to evaluate the reliability and responsiveness of the incremental shuttle walk test (ISWT) to estimate exercise capacity in patients with pulmonary arterial hypertension (PAH). This was a cross-sectional longitudinal study performed on stable PAH patients (n=30, mean age ± standard deviation, 60±13.6 years) with World Health Organization functional class II & III. Reliability was assessed by comparing the distance covered between ISWT-1 (initial) and ISWT-2 (retest). Responsiveness was determined by comparing the distance covered in the ISWT-3 post pulmonary rehabilitation (PR) to the ISWT-1. The distance covered between ISWT-1 (177±87.85 m) and ISWT-2 (191.67±96.39 m) was not statistically significant. The result of the relative reliability has shown to be excellent with an intraclass correlation coefficient (ICC2,1= 0.98, 95%CI = 0.95-0.99). Absolute reliability was evaluated through the standard error of the measurement and minimal detectable change at a 95% confidence interval (MDC95) were 12.29 and 33.9 m, respectively. Bland Altman plot showed good agreement between the two ISWTs. Following PR, the effect size (ES=0.78) and standardised response mean (SRM=1.50) were moderate and large respectively. ISWT is considered to be a reliable and responsive measure to estimate exercise capacity in patients with PAH. The ISWT may be considered a suitable alternative tool over a 6-min walk test and in the absence of equipment availability or expertise for conducting cardiopulmonary exercise test for the assessment of exercise capacity in these patients.

Abstract
IMPORTANCE Survivors of acute pulmonary embolism (PE) experience long-term negative physical and mental consequences, but the effects of rehabilitation on outcomes among these patients have not been investigated. OBJECTIVE To investigate the effect of a rehabilitation intervention, comprising an 8-week home-based exercise program and nurse consultations, on physical capacity and patient-reported outcomes among patients with acute PE. DESIGN, SETTING, AND PARTICIPANTS This multicenter randomized clinical superiority trial was conducted at 4 regional hospitals and 1 university hospital in Denmark. The 140 consecutively included participants had been diagnosed with an acute PE between April 2016 and February 2018 and had 6 months of follow-up. An intention-to-treat analysis was conducted. INTERVENTION Patients in the control group received a brief nurse consultation, while patients in the exercise group participated in an 8-week home-based exercise program in addition to receiving nurse consultations. MAIN OUTCOMES AND MEASURES The primary outcome was the Incremental Shuttle Walk Test, and secondary outcomes were the Pulmonary Embolism Quality of Life and the EuroQol-5 Dimensions-3 Levels questionnaires, self-reported number of sick-leave days, and self-reported use of psychotropic drugs. RESULTS A total of 140 patients (90 [64.3%] men) were included, with a mean (SD) age of 61 (11) years. Of 70 participants (50.0%) randomized to each group, 69 participants (49.3%) received the intervention and 68 (48.6%) received the control intervention. Both groups achieved improvements in all outcomes (eg, mean [SD] improvement on Incremental Shuttle Walk Test: control group, 78 (127) m; intervention group, 104 [106] m; median [interquartile range] improvement on Pulmonary Embolism Quality of Life: control group, -17 [-22 to -11] points; intervention group, -20 [-24 to -15] points). Between-group differences were nonsignificant. The mean differences between the intervention group and the control group were 25 m (95% CI, -20 to 70 m; P = .27) on the Incremental Shuttle Walk Test, 3.0 points (95% CI, -3.7 to 9.9 points; P = .39) on the Pulmonary Embolism Quality of Life questionnaire, and 0.017 point (95% CI, -0.032 to 0.065 point; P = .50) on the EuroQol-5 Dimensions-3 Levels questionnaire. Of the 27 patients in the intervention group on sick leave at baseline, 24 (88.9%) reported fit-for-duty at the 6-month follow-up, and of 18 patients in the control group on sick leave, 17 (94.4%) reported fit-for-duty at the 6-month follow up. The between-group risk difference was not significant (5.5 points; P = .49). CONCLUSIONS AND RELEVANCE An 8-week rehabilitation intervention with exercise added to nurse consultations did not show significantly better outcomes than nurse consultations alone. However, because of a ceiling effect on the primary outcome of physical capacity and an inclusion of patients with a low comorbidity burden and low PE disease severity, definitive conclusions could not be drawn. Initiating an exercise intervention shortly after pulmonary embolism was safe and without adverse events. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02684721.

Abstract
<LEAP> Highlights the findings and application of Cochrane reviews and other evidence pertinent to the practice of physical therapy. The Cochrane Library is a respected source of reliable evidence related to health care. Cochrane systematic reviews explore the evidence for and against the effectiveness and appropriateness of interventions-medication, surgery, education, nutrition, and exercise-and the evidence for and against the use of diagnostic tests for specific conditions. Cochrane reviews are designed to facilitate the decisions of clinicians, patients, and others in health care by providing a careful review and interpretation of research studies published in the scientific literature. Each article in this Physical Therapy (PTJ) series will summarize a Cochrane review or other scientific evidence resource on a single topic and will present clinical scenarios based on real patients to illustrate how the results of the review can be used to directly inform clinical decisions. This article focuses on the effectiveness of supervised exercise therapy for intermittent claudication. Can supervised exercise therapy help a person with intermittent claudication?

Abstract
OBJECTIVE The modified shuttle test is a field test that avoids the ceiling effect, and there are no reports of a multidimensional assessment concerning physical activity in asthmatic patients. Thus, the aim was to evaluate functional capacity by MST, additionally to perform a multidimensional assessment as physical activity in daily life, muscle strength, and cytokine levels in children and adolescents with asthma, and to correlate these variables. METHOD This cross-sectional study included volunteers aged between 6 and 18 years who were divided into two groups: asthma group (n=43) that received regular treatment and control group (n=24). Functional capacity was evaluated by distance walked during the MST; physical activity in daily life was evaluated using an accelerometer by the number of steps. Quadriceps femoris strength was evaluated by load cell. RESULTS Distance walked was lower for the asthma group (790m [222m]) when compared with the control group (950m [240m]; p=0.007); however, the number of steps was similar between the two groups (asthma group: 7743 [3075]; control group: 7181 [3040]; p=0.41), and both groups were classified as sedentary behavior. There was no difference in muscle strength. Tumor necrosis factor-α differed, but interleukin levels were similar between groups. Quadriceps strength was correlated to distance walked (r=0.62; p<0.001) and tumor necrosis factor-α to the number of steps taken (r=-0.54, p=0.005). CONCLUSION Children and adolescents undergoing regular asthma treatment showed reduced functional capacity and sedentary behavior. The lower the quadriceps strength, the shorter the distance walked; the higher the tumor necrosis factor-α levels, the lower their daily physical activity levels.

Abstract
RESUMO O objetivo deste estudo foi traduzir e adaptar a escala de utilidade clínica de Tyson e Connell para o português brasileiro, além de avaliar sua confiabilidade interexaminador e intraexaminador. O processo de tradução e adaptação transcultural foi desenvolvido em cinco estágios: tradução; síntese das traduções; retrotradução; avaliação pelo comitê de especialistas; e teste da versão pré-final. Para avaliação da confiabilidade intra e interexaminador da escala, 20 instrumentos de avaliação foram analisados de forma independente por dois examinadores (confiabilidade interexaminador). Além disso, um dos examinadores fez todas as avaliações, em dois momentos distintos, com um intervalo de 30 dias entre uma e outra (confiabilidade intraexaminador). A tradução e a adaptação transcultural foram realizadas de forma sistemática, seguindo os critérios propostos, de modo que houve apenas pequenas alterações em dois itens para tornar a escala mais útil a todos os instrumentos disponíveis na literatura. Em relação à confiabilidade interexaminador da escala de utilidade clínica de Tyson e Connell-Brasil, o valor encontrado foi CCI=0,85 (IC 95%, 0,79-0,87), enquanto para a confiabilidade intraexaminador o resultado foi CCI=0,89 (IC 95%, 0,85-0,93). Os resultados deste processo indicaram adequado grau de equivalência semântica, conceitual e cultural. Além disso, as medidas de confiabilidade intra e interexaminadores foram consideradas adequadas. Esses achados demonstraram que a escala é adequada para avaliar a utilidade clínica de instrumentos de avaliação comumente utilizados em pacientes. Dessa forma, deve ser incorporada na prática clínica e em pesquisas para a escolha do melhor instrumento.

Abstract
RESUMO O objetivo deste estudo foi avaliar e comparar respostas metabólicas, cardiovasculares e ventilatórias do incremental shuttle walk test (ISWT) e do Glittre activities of daily living test (Glittre-ADL test). Trata-se de um estudo transversal, realizado com indivíduos saudáveis. A capacidade funcional (CF) foi avaliada pela distância percorrida e consumo de oxigênio pico (VO2pico) no ISWT e pelo tempo gasto e VO2 no Glittre-ADL test. Trinta indivíduos percorreram 656,67 (IC95%:608,8-704,5) metros no ISWT e executaram o Glittre-ADL test em 2,4 (IC95%:2,2-2,6) minutos. O VO2 pico do ISWT foi 27,8 (IC95%25,6-29,9) versus 22,2 (IC95%20,5-24,1)mL×kg−1×min−1 (p<0,001) no estado estável (EE) do Glittre-ADL test. As correlações entre distância percorrida no ISWT e o tempo gasto no Glittre-ADL test, o VO2pico do ISWT e o VO2 no EE do Glittre-ADL test e a FC no pico do ISWT e no EE do Glittre-ADL test foram de moderada a alta magnitude. O Glittre-ADL test apresenta menores respostas metabólicas, cardiovasculares e ventilatórias se comparado ao ISWT.

Abstract
PURPOSE To determine the reliability, validity, and responsiveness of the incremental shuttle walk test (ISWT) in patients with interstitial lung disease (ILD). METHODS This was a cross-sectional longitudinal study. Patients (n = 27, 10 males; mean age ± SD, 61 ± 9.8 y) with ILD of any etiology, who participated in an outpatient pulmonary rehabilitation (PR) program, were recruited. Reliability was determined by comparing the distance covered in meters between the ISWT-1 and the ISWT-2. Validity was assessed by correlating the distance covered in the ISWT-1, with the maximum oxygen consumption ((Equation is included in full-text article.)O2max) obtained through cardiopulmonary exercise testing and distance covered during the 6-min walk test (6MWT). Responsiveness was assessed by comparing the distance covered in the ISWT-3, undertaken after the completion of PR, to the ISWT-1. RESULTS The distance covered was equivalent between the ISWT-1 (216.7 ± 64.9 m) and the ISWT-2 (220.7 ± 67.3 m), with an excellent intraclass correlation coefficient (ICC2,1 = 0.91; 95% CI, 0.81-0.95). The standard error of measurement and minimal detectable change at the 95% CI (MDC95) values for the ISWT were 19.5 m and 53.9m, respectively. There were significant correlations between the distance covered on the ISWT and (Equation is included in full-text article.)O2max (r = 0.79, P < .0001) and the distance covered on the 6MWT (r = 0.76, P < .0001). Following PR, the change in the ISWT distance showed large effect size (ES = 0.85) and standardized response mean (SRM = 1.58). CONCLUSIONS The ISWT is a reliable, valid, and responsive measure of estimated functional capacity in patients with ILD.

Abstract
BACKGROUND The incremental shuttle walk test (ISWT) is one of the most widely used field tests to assess cardiorespiratory fitness in clinical and research settings. Reference equations to predict ISWT distance in different populations and age cohorts have been established. However, an equation for the Portuguese pediatric population is not available. This study aimed to develop a reference equation for predicting ISWT in Portuguese children and adolescents. METHOD Healthy children and adolescents aged between 5 and 17 years old were recruited. Sociodemographic (sex, age), anthropometric (height, weight) and physical activity (Physical Activity Index) data were collected. Lung function was assessed through spirometry and quadriceps muscular strength through hand-held dynamometry. The ISWT was performed twice. A reference equation was established with a multiple linear regression. RESULTS 130 (60 male; 13.66±2.61y) participants with normal lung function (forced expiratory volume in one second 102.73±15.09% predicted), body mass index (BMI) (20.27±3.59kg/m2) and quadriceps muscular strength (19.75±6.84kgf), completed the assessment. 50.8% (n=66) of the participants were moderately active. Participants walked on average 1165.08±327.19m in the ISWT. Sex, age and BMI were independent contributors to the ISWT, explaining 54% of its variability (p<0.001). The derived reference equation was: ISWT=342.06+(283.07×sex)+(83.61×age)-(22.22×BMI), with female=0 and male=1. CONCLUSION Sex, age and BMI were found to be contributors to the ISWT predictive equation for pediatric population, providing a simple reference to assess their cardiorespiratory fitness.

Abstract
Pulmonary hypertension (PH) is classified into five groups based on disease etiology but there is only limited information on the prognostic value of exercise testing in non-group 1 PH. In group 1 PH, the incremental shuttle walking test (ISWT) distance has been shown to correlate with pulmonary hemodynamics and predict survival without a ceiling effect. This study assessed the ISWT in non-group 1 PH. Data were retrieved from the ASPIRE Registry (Assessing the Spectrum of Pulmonary hypertension Identified at a REferral centre) for consecutive patients diagnosed with PH. Patients were required to have been systematically assessed as group 2-5 PH and to have a baseline ISWT within three months of cardiac catheterization. Patients were stratified according to incremental shuttle walk test distance (ISWD) and ISWT distance percent predicted (ISWD%pred). A total of 479 patients with non-group 1 PH were identified. ISWD and ISWD%pred correlated significantly with symptoms and hemodynamic severity. ISWD and ISWD%pred predicted survival with no ceiling effect. The test was prognostic in groups 2, 3, and 4. ISWD and ISWD%pred and change in ISWD and ISWD%pred at one year were all significant predictors of outcome. In patients with non-group 1 PH the ISWT is a simple non-invasive test that is easy to perform, is predictive of survival at baseline and follow-up, reflects change, and can be used in the assessment of PH of any etiology.

Respirology 2019; 24:752-757.

Abstract
BACKGROUND AND OBJECTIVE We investigated the repeatability and validity of the incremental shuttle walk test (ISWT) distance compared to peak oxygen uptake (VO2pk ) during maximal incremental cycle ergometer (ICE) and treadmill (ITM) tests in adults with severe asthma. METHODS Adults with severe asthma, Medical Research Council (MRC) dyspnoea ≥2, were recruited from specialists caring for patients with severe asthma. All participants performed three ISWT (familiarization and two subsequent tests on the same day), an ICE and an ITM in a randomized order, on separate days, to intolerance with expiratory gas analysis. RESULTS A total of 50 patients (32 females, mean (SD), age: 54 (13) years, forced expiratory volume in 1 s (FEV1 ): 1.9 (0.8) L and body mass index (BMI): 32 (6) kg/m2 ) completed all five tests. The mean (SD) ISWT distance for each test was 400 (156), 418 (142) and 438 (157) m (P = 0.001), respectively. There was a strong correlation between the ISWT distance with VO2pk derived from ITM (r = 0.74, P < 0.001) and ICE (r = 0.75, P < 0.001). CONCLUSION There was a small increase in the mean ISWT distance on sequential testing. In clinical practice, the coefficient of repeatability and heteroscedasticity need to be considered when assessing whether a true change has occurred within an individual patient. The ISWT has validity compared to VO2pk on both ICE and ITM, but they are not interchangeable.

Abstract
This study investigated the influence of cardiac intervention and physical capacity of individuals attending an Australian outpatient cardiac rehabilitation program on the initial exercise prescription. A total of 85 patients commencing outpatient cardiac rehabilitation at a major metropolitan hospital had their physical capacity assessed by an incremental shuttle walk test, and the initial aerobic exercise intensity and resistance training load prescribed were recorded. Physical capacity was lower in surgical patients than nonsurgical patients. While physical capacity was higher in younger compared with older surgical patients, there was no difference between younger and older nonsurgical patients. The initial exercise intensity did not differ between surgical and nonsurgical patients. This study highlights the importance of preprogram exercise testing to enable exercise prescription to be individualized according to actual physical capacity, rather than symptoms, comorbidities and age, in order to maximize the benefit of cardiac rehabilitation.

Abstract
INTRODUCTION Type 2 diabetes is common in Māori and Pacific peoples and in those living in areas of high socioeconomic deprivation in New Zealand (NZ). People with type 2 diabetes often have multimorbidity, which makes their diabetes management more complex. The Diabetes Community Exercise and Education Programme (DCEP) is an interprofessional, patient-centred, whānau (family)-supported package of care specifically developed to engage with Māori and Pacific people and those living in deprived areas. We have previously demonstrated the feasibility and acceptability of the DCEP. This study aims to determine the effectiveness and cost-effectiveness of the DCEP through a pragmatic randomised controlled trial (RCT). METHODS AND ANALYSIS 220 adults (age ≥35 years) with type 2 diabetes will be recruited from general practices in the lower South Island of NZ (Dunedin and Invercargill) to participate in an RCT. Participants will be randomised to intervention (DCEP) and control (usual care) groups. The DCEP participants will have their exercise goals agreed on with a physiotherapist and nurse and will attend two 90 min exercise and education sessions per week for 12 weeks. The primary outcome measure is blood glucose control (glycated haemoglobin). Secondary outcome measures include quality of life assessed using the Audit of Diabetes-Dependent Quality of Life questionnaire. Data will be collected at four time points: baseline, end of the 12-week intervention (3 months), 6 months postintervention (9 months) and 12 months after the intervention ends (15 months). We will also conduct a cost-effectiveness analysis and a qualitative process evaluation. ETHICS AND DISSEMINATION The study has been approved by the Health and Disability Ethics Committee, Ministry of Health (HDEC17/CEN/241/AM01). A key output will be the development of an evidence-based training package to facilitate implementation of the DCEP in other NZ regions. TRIAL REGISTRATION NUMBER ACTRN 12617001624370 p; Pre-results.
