Long-Term Declines in Physical Fitness and Physical Activity for Individuals With Post-Liver Transplantation Compared to Healthy Controls.

Functional changes are essential determinants of mortality and morbidity in individuals with chronic liver disease. However, there is limited information about whether these changes persist long-term after liver transplantation (LT). We aimed to compare physical fitness, physical activity, balance, kinesiophobia, and fatigue between patients with LT and healthy controls. All participants underwent evaluation with the Senior Fitness Test (SFT) for exercise capacity and physical fitness, the International Physical Activity Questionnaire (IPAQ) for physical activity, the Timed Up-and-Go Test (TUG) and the Berg Balance Scale (BBS) for balance, the Tampa Scale for Kinesiophobia (TSK) for kinesiophobia, and the Fatigue Severity Scale (FSS) and Fatigue Impact Scale (FIS) for fatigue. We studied 16 persons with LT (M age = 40.56, SD = 15.73 years; M time since LT = 66.81, SD = 72.05 months) and 16 control participants (M age = 39.87, SD = 13.98 years). Compared to controls, participants with LT showed significantly poorer performance on the SFT components assessing upper and lower body strength, aerobic endurance, agility, and dynamic balance (p < .001 for all), significantly lower IPAQ physical activity scores (p = .002) and BBS score (p = .017), and significantly higher TUG time (p < .001) and TSK, FSS, and FIS scores (p = .001, p = .001, and p = .004, respectively). Individuals with post-LT had lower exercise capacity, physical fitness, balance, and physical activity, and higher kinesiophobia and fatigue levels in the long-term compared to their peers. Future studies should focus on frailty in individuals in the long term after LT.

Energy expenditure and glucose-lowering effect of different exercise modalities in diabetes mellitus.

OBJECTIVES: Hypoglycaemia is a serious complication of exercise in patients with type 2 diabetes mellitus (T2DM). The aim of this study was to test energy expenditure and the degree of the glucose-lowering effect of different exercise modalities. DESIGN: Cross-sectional study PARTICIPANTS: This study included 44 patients {35 women and nine men, mean age 51 [standard deviation (SD) 5] years} with T2DM [mean HbA1c 7% (SD 1%)]. MAIN OUTCOME MEASURES: Standardised exercise tests for walking, running and cycling were performed using the 6-minute walk test (6MWT), incremental shuttle walk test (ISWT), and symptom-limited maximal cycle exercise test, respectively. Energy expenditure was assessed with a multisensory accelerometer. Change in capillary glucose levels (∆glucose) was measured before and after each exercise modality. RESULTS: ∆Glucose was lower in the 6MWT {median 14 [interquartile range (IQR) 22] mg/dl} than in the ISWT [median 18 (IQR 23) mg/dl; median difference 7 mg/dl, 95% confidence interval (CI) of the difference 3-11] and the cycle test [median 18 (IQR 24) mg/dl; median difference 7 mg/dl, 95% CI 0-16]. Energy expenditure was lower during the 6MWT [median 41 (IQR 18) Kcal] compared with the ISWT [median 51 (IQR 23) Kcal; median difference 11 Kcal, 95% CI 6-16] and the cycle test [median 44 (IQR 25) Kcal; median difference 6 Kcal, 95% CI 0-13]. CONCLUSIONS: Energy expenditure and corresponding glucose-lowering effect during exercise in patients with T2DM can be predicted from the results of an exercise test. The type of exercise is related to the risk of hypoglycaemia. Walking is associated with the lowest energy expenditure and risk of hypoglycaemia, while cycling and running/jogging cause higher energy expenditure and greater reductions in glucose in patients with T2DM.

Daily living activities, exercise capacity, cognition, and balance in COPD patients with and without frailty.

BACKGROUND: Information on the interaction between frailty and chronic obstructive pulmonary disease (COPD) is limited. AIMS: This study aimed to compare activities of daily living (ADL), exercise capacity, balance, and cognition in COPD patients with and without frailty. METHODS: Twenty frail and 28 non-frail COPD patients aged 55 years and over were included. Frailty was determined according to Fried et al. Dyspnea was evaluated using the modified Medical Research Council (mMRC) dyspnea scale. Respiratory and peripheral muscle strength were measured. Functional capacity was assessed using a 6-min walk test (6MWT); ADL performance was evaluated using the Glittre ADL test. The balance was evaluated using the functional reach test (FRT). Cognitive function was assessed using the Montreal Cognitive Evaluation (MoCA) Test. Quality of life was measured using the COPD Assessment Test (CAT). RESULTS: The mMRC and CAT scores were higher in the frail patients as compared with the non-frail patients (p < 0.05). The maximal inspiratory pressure, handgrip strength, 6MWT distance, and FRT score were lower in the frail patients as compared with the non-frail patients (p < 0.05). The duration for the Glittre ADL test was longer in the frail patients than the non-frail patients (p < 0.05). There was no significant difference between MoCA scores between groups (p > 0.05). CONCLUSIONS: Frail COPD patients have increased dyspnea perception, impaired muscle strength, and functional capacity, ADL performance, balance, and quality of life. Whether pulmonary rehabilitation programs for patients with frail COPD need to be adapted with new rehabilitation strategies, including components of frailty, needs further investigation.

Validity and reliability of 6-minute pegboard and ring test in patients with asthma.

OBJECTIVE: The 6-minute pegboard and ring test (6PBRT) is a test of upper-extremity functional capacity designed for and validated in chronic obstructive pulmonary disease. The aim of this study was to evaluate the validity and reliability of the 6PBRT in asthma patients. METHODS: Thirty-four adults (30 women, 4 men) with well-controlled asthma were included. Unsupported upper-extremity exercise capacity was assessed using 6PBRT, maximal arm exercise capacity using an arm ergometer, handgrip strength using a hand dynamometer, activities of daily living with the London Chest Activities of Daily Living Scale (LCADL), Milliken ADL scale (MAS) and health-related quality of life using the Asthma Quality of Life Questionnaire (AQLQ) and Health Assessment Questionnaire Disability Index (HAQ-DI). RESULTS: The 6PBRT showed moderate to excellent test-retest reliability with an intraclass correlation coefficient (ICC) value of 0.872 [95% confidence interval (CI) 0.702-0.941]. The 6PBRT was reproducible according to Bland-Altman analysis, with upper and lower limits of agreement of 53.51 and -25.08 rings moved, respectively. The 6PBRT score was significantly correlated with maximum workload (r = 0.514, p = 0.002) achieved in the arm ergometer test, change in dyspnea during 6PBRT (r = -0.402, p = 0.020), LCADL-self-care (r = -0.364, p = 0.037), MAS total (r = 0.483, p = 0.005), AQLQ-symptom domain (r = 0.420, p = 0.026) and HAQ-DI total scores (r = -0.390, p = 0.025). CONCLUSIONS: The 6PBRT can be used as a valid and reliable test to evaluate functional arm exercise capacity in patients with well-controlled asthma.

Physical fitness and activities of daily living in primary ciliary dyskinesia: A retrospective study.

BACKGROUND: Primary ciliary dyskinesia (PCD) is a rare, hereditary, autosomal recessive disorder characterized by recurrent upper and lower respiratory tract infections. This study aimed to compare pulmonary function, respiratory muscle strength, exercise capacity, physical fitness, and activities of daily living (ADLs) retrospectively between patients with PCD and healthy controls. METHODS: Data from 20 patients with PCD and 20 matched, healthy counterparts recorded between July 2015 and January 2017 were analyzed. The data evaluated and recorded included pulmonary function using a portable spirometer, respiratory muscle strength (using a mouth pressure device, exercise capacity using the incremental shuttle walk test,), physical fitness (using the Munich Fitness Test), and ADLs (using the Glittre ADL test). RESULTS: Pulmonary function, respiratory muscle strength, incremental shuttle walk test scores (all parameters), and total Munich Fitness Test scores were lower in the PCD group relative to controls (P < 0.05). The duration to complete the Glittre ADL test was higher in PCD patients than in healthy subjects (P < 0.05). CONCLUSIONS: Pulmonary function, respiratory muscle strength, exercise capacity, physical fitness, and ADL were affected by PCD. Thus, pulmonary rehabilitation regimens should be tailored according to these impacts.

Physical activity patterns in children with cerebral palsy and typically developing peers.

Objective: To compare physical activity level between children with cerebral palsy and typically developing peers using accelerometer and activity diary.Method: Twenty children with spastic cerebral palsy Level I and II according to Gross Motor Function Classification System, and 20 healthy age- and sex-matched typically developing peers were included. An activity diary was logged, and each child wore an accelerometer for 4 days, 2 weekdays and 2 weekend days.Results: Total and physical activity energy expenditure assessed using either accelerometer or activity diary was markedly lower in children with spastic cerebral palsy compared to typically developing peers. Moderate and vigorous physical activities and daily total energy expenditure assessed using activity diary were significantly lower in children with cerebral palsy than those of typically developing peers (p < .05). There was a significant relationship between accelerometer and activity diary in total energy expenditure for children with cerebral palsy (r = 0.752, p < .001) and typically developing peers (r = 0.732, p < .001) and a moderate significant relationship in physical activity energy expenditure for children with cerebral palsy (r = 0.463, p = .040).Conclusion: In this study, children with cerebral palsy had lower physical activity levels than their typically developing peers. The activity diary provided detailed information about physical activities and was correlated with accelerometer data. The activity diary could be a valid measure of physical activity levels in children with cerebral palsy.

Evaluation of exercise capacity using two field tests in patients with metabolic syndrome.

PURPOSE: Field tests are popular for assessing exercise capacity because they are practical and have established validity. The objective of this study was to compare physiological responses and exercise performance of patients with metabolic syndrome in two field tests of exercise capacity. MATERIAL AND METHODS: Forty-seven patients diagnosed with metabolic syndrome participated in this cross-sectional study. Exercise capacity was assessed using incremental shuttle walk test and six-minute walk test. Factors determining exercise capacity and agreement between the two tests were also investigated. RESULTS: Metabolic syndrome patients achieved a significantly greater percentage of predicted maximal heart rate, blood pressure, and longer distance in the incremental shuttle walk test than in the six-minute walk test (p < 0.001). Gender and body mass index explained 48.5% of the variance in six-minute walk test distance (R = 0.697, R2 = 0.485, F(2-46) = 20.737, p < 0.001). Body mass index and fat-free mass explained 55% of the variance in incremental shuttle walk test distance (R = 0.746, R2= 0.557, F(2-46) = 27.623, p < 0.001). CONCLUSIONS: Despite the agreement in the percentages of predicted maximal heart rate during these two field tests, the incremental shuttle walk test may be a better assessment tool than the six-minute walk test because it elicits more pronounced and definitive physiological responses to exercise tolerance in patients with metabolic syndrome.IMPLICATIONS FOR REHABILITATIONThe incremental shuttle walk test can be used to evaluate exercise capacity in metabolic syndrome.The incremental shuttle walk test elicits greater physiological responses than the six-minute walk test.The incremental shuttle walk test may be preferable over the six-minute walk test in investigating exercise capacity.Both tests can guide and assist in the evaluation of this patient population in clinical practice.Body mass index affected distance in both exercise tests.

Association between 6 min pegboard and ring test and arm performance in GOLD stage II-III patients.

BACKGROUND: The 6 min pegboard and ring test (6PBRT) is a valid and reproducible test of unsupported arm exercise endurance. The aim of this study was to determine the associations between the 6PBRT, activities of daily living (ADL) and hemoglobin levels in chronic obstructive pulmonary disease (COPD). METHODS: This study included 40 stable patients with COPD. All participants underwent the 6PBRT, peripheral venous blood sampling, arm ergometer test and the Glittre-ADL and ADL simulation tests for the ADLs performance. RESULTS: An average 172.51 ± 25.94 rings were moved in 6 min. The number of rings in 6PBRT was significantly positively correlated with the number of cycles in ADL simulation test (r = 0.553, p < 0.001), peak oxygen consumption in arm ergometer (r = 0.381, p = 0.024) and serum hemoglobin level (r = 0.411, p = 0.011). CONCLUSION: The number of rings moved in the 6PBRT is associated with ADL simulation test performance that reflects upper extremity ADLs. Therefore, the 6PBRT can be used for estimating limitation in upper extremity ADLs as a simple and quick evaluation in patients with GOLD stage II-III COPD.

Sustainable inspiratory pressure and incremental threshold loading for respiratory muscle endurance in chronic obstructive pulmonary disease: A pilot study.

INTRODUCTION: A prolonged mismatch between the demand for respiratory muscle work and the capacity to meet that demand in chronic obstructive pulmonary disease (COPD) can result in symptoms of dyspnea and the development of muscle fatigue. OBJECTIVES: The purpose of this study was to compare two different respiratory muscle endurance assessment methods of sustainable inspiratory pressure (SIP) and incremental threshold loading (ITL) in COPD. METHODS: Thirty-four patients diagnosed with COPD were included in the study. Physical and demographic characteristics of the subjects were recorded. Pulmonary function testing (PFT), modified Medical Research Council (MMRC) dyspnea scale, COPD assessment test, inspiratory and expiratory muscle strength (MIP and MEP, respectively) measurement and six-minute walk test (6MWT) were used to assess subjects. Two different respiratory muscle endurance tests (SIP and ITL) were performed within 48 hours apart, and each test was repeated two times on the same day. RESULTS: There was no correlation between the SIP and ITL tests (r = 0.069, P = .699). According to the test-retest reliability analysis, both tests were reproducible (ICC = 0.843; P < .001 for SIP, ICC = 0.905; P < .001 for ITL). Finding no differences between repeated tests showed that tests are not affected by learning effect. CONCLUSION: The SIP and ITL tests are used for the same purpose but have different characteristics. Regarding the relationship between the other parameters and tests, the ITL is well tolerated and reflects the differences in respiratory muscle endurance better.

Respiratory Dysfunction in Individuals With Thoracic Outlet Syndrome.

OBJECTIVE: The purpose of this study was to compare pulmonary function and respiratory muscle strength and endurance in individuals with thoracic outlet syndrome (TOS) and healthy participants. METHODS: Sixty-two individuals with TOS (mean age 30.81 ± 10.69 years; 10 male, 52 female) and 47 healthy individuals (mean age 30.64 ± 9.16 years; 14 male, 33 female) participated in this study. Pulmonary function testing was performed using a spirometer. Respiratory muscle strength (maximal inspiratory pressure [MIP] and maximal expiratory pressure [MEP]) were measured using a mouth pressure device. Respiratory muscle endurance was tested at 35% MIP and measured as the time in seconds from the start of the test to voluntary exhaustion. RESULTS: Age distribution and physical characteristics were similar between the groups (P > .05). All pulmonary function parameters except for peak expiratory flow rate were similar in patients with TOS and healthy controls (P > .05). Patients with TOS had significantly lower peak expiratory flow rate, MIP, MIP%, MEP, MEP%, and respiratory muscle endurance compared with controls (P < .05). Forty-six patients with TOS (74.2%) had MIP values below the lower limit of the 95% CI of the control group (97.05-113.88 cmH2O), and 53 patients with TOS (85.2%) had MEP values below the lower limit of the 95% CI of the control group (124.74-146.49 cmH2O). CONCLUSION: Expiratory flow rate and respiratory muscle strength and endurance may be adversely affected in TOS. Trunk muscles perform both postural and breathing functions. Therefore, disruption in one function may negatively affect the other.

The effectiveness of oropharyngeal exercises compared to inspiratory muscle training in obstructive sleep apnea: A randomized controlled trial.

BACKGROUND: Inspiratory muscle training (IMT) and oropharyngeal exercises (OE) have different advantages and disadvantages and a comparison of these modalities has been recommended. The aim of this study was to compare the effects of IMT and OE on important outcomes for patients with OSAS. METHODS: This was a randomized controlled clinical trial. Forty-one clinically stable OSAS patients not receiving CPAP therapy were randomly divided into three groups. Patients in the IMT group (n = 15) trained with a threshold loading device 7 days/week for 12 weeks. Patients in the OE group (n = 14) practiced exercises 5 days/week for 12 weeks. Twelve patients served as control group. Apnea-hypopnea index (AHI), respiratory muscle strength, snoring severity and frequency (Berlin Questionnaire), daytime sleepiness (Epworth Sleepiness Scale; ESS), sleep quality (Pittsburg Sleep Quality Index; PSQI), impact of sleepiness on daily life (Functional Outcomes of Sleep Questionnaire; FOSQ), and fatigue severity (Fatigue Severity Scale; FSS) were evaluated before and after the interventions. RESULTS: AHI and sleep efficiency did not change significantly in any of the groups. Significant decreases in snoring severity and frequency, FSS and PSQI total scores were found in the IMT and OE groups after the treatments (p < 0.05). There was a significant reduction in neck and waist circumference and significant improvement in respiratory muscle strength (MIP and MEP) in IMT group compared to control group (p < 0.05). The%MEPpred value and FOSQ total score significantly increased and ESS score reduced after the treatment in OE group compared to control group (p < 0.05). CONCLUSIONS: Our results indicate that both OE and IMT rehabilitation interventions are applicable in rehabilitation programs for OSAS patients who do not accept CPAP therapy. Our findings could lead to increase these methods' use among rehabilitation professionals and decrease in cost of CPAP treatment in OSAS.

Subclinical Inflammation Is Associated With Reductions in Muscle Oxygenation, Exercise Capacity and Quality of Life in Adults With Type 2 Diabetes.

OBJECTIVES: Exercise capacity is related to both morbidity and mortality in patients with type 2 diabetes (T2DM). The aim of this study was to investigate the relationship between subclinical inflammation level, exercise capacity, muscle oxygenation and quality of life in T2DM. METHODS: This study includes 28 patients with T2DM (mean age, 51.5±5.0 years; male-to-female ratio, 6:22). Exercise capacity was evaluated using an incremental symptom-limited maximal exercise test on a bicycle ergometer. Muscle oxygenation was investigated using a wearable lactate-measuring device. Diabetes-specific quality of life was assessed using the Diabetes Quality of Life Questionnaire (DQOL). Subclinical inflammation was assessed using C-reactive protein (CRP) levels. RESULTS: CRP level was negatively correlated with peak workload during the test (r=-0.588, p=0.002), muscle oxygenation (r=-0.465, p=0.019) and the psychological impact of treatment subscale of the DQOL (r=-0.540, p=0.017), and positively correlated with body mass index (r=0.519, p=0.008), waist circumference (r=0.426, p=0.038) and fat percentage (r=0.573, p=0.004). There was no correlation between CRP and fasting blood glucose or glycated hemoglobin level (p>0.05). Peak workload was inversely related to fat percentage (r=-0.467, p=0.016) and the DQOL worry about the future impact of diabetes subscale (r=-0.501, p=0.021). CONCLUSIONS: In our study, subclinical inflammation negatively affected muscle oxygenation, exercise capacity and quality of life independently of glycemic indicators. Our findings suggest that the degree of glycemic control is insufficient to explain lower exercise capacity. Further studies are needed to investigate subclinical inflammation-reducing interventions in T2DM.

Levels of Physical Activity and Physical Fitness in Pediatric Pacemaker Patients: A Cross-Sectional Study.

Children with heart diseases have reduced physical activity (PA) levels relative to their peers, which in turn increases cardiovascular risk. To the best of our knowledge, physical fitness and objectively measured PA levels have not been previously studied in children with pacemakers. We evaluated PA levels and physical fitness in pediatric pacemaker patients compared to their healthy peers. Twenty-eight pediatric patients with pacemakers (15 female, 13 male; mean age 13.43 ± 3.68 years) and 24 healthy subjects (14 female, 10 male; mean age 13.08 ± 3.67 years) were included. Physical fitness was assessed using the Munich Fitness Test (MFT). SenseWear Armband metabolic Holter device was used to record the PA for 7 consecutive days. MFT total and sub-parameter scores were significantly lower in the patient group (p < 0.05). Patients' total and active energy expenditure, PA level, total distance, number of steps, and vigorous PA were significantly lower than those of healthy children (p < 0.05). Sedentary activity and light, moderate, and very vigorous PA durations were similar in both groups (p > 0.05). Duration of mean moderate to vigorous PA was higher than 60 min/day recommended in PA guidelines in both patients and healthy subjects. These results provide initial data on PA and fitness in children with pacemakers and suggest that physical fitness and activity levels in children with pacemakers are lower than in healthy peers. Appropriate exercise programs may improve PA levels in pediatric pacemaker patients. Awareness of the importance of PA should be raised among the parents and families of these children.

Visuomotor reaction time and dynamic balance in children with cystic fibrosis and non-cystic fibrosis bronchiectasis: A case-control study.

OBJECTIVE: Extrapulmonary involvement such as balance and reaction time is unclear in cystic fibrosis (CF) patients. The aim of this study was to evaluate visuomotor reaction time (VMRT) and dynamic balance in children with CF and non-CF bronchiectasis compared to healthy children. DESIGN/METHODS: Demographic and clinical characteristics were recorded. All children were evaluated with pulmonary function test (PFT) using a spirometer, incremental shuttle walk test (ISWT) for exercise capacity, Fitlight Trainer for VMRT, and functional reach test (FRT) for dynamic balance. RESULTS: Fourteen children with CF (10.71 ± 2.94 years, 7 females), 17 children with non-CF bronchiectasis (12.75 ± 2.81 years, 8 females), and 21 healthy children (11.36 ± 3.28 years, 11 females) were included. Children with CF had longer total VMRT (P = .027), poorer FRT performance (P = .001), and shorter ISWT distances (P = .03) compared to the children with non-CF bronchiectasis and controls. Although total VMRT was longest in the CF group, there was no significant difference in mean VMRT among the CF, non-CF bronchiectasis, and control groups (P > .05). CONCLUSION: Dynamic balance and VMRT show greater impairment in children with CF than in children with non-CF bronchiectasis compared to healthy controls. Our findings suggest that VMRT and dynamic balance should be taken into consideration for assessments and exercise programs in pulmonary rehabilitation.

Exercise Capacity and Activities of Daily Living are Related in Patients With Chronic Obstructive Pulmonary Disease / La capacidad de ejercicio y las actividades de la vida diaria están relacionada en pacientes con enfermedad pulmonar obstructiva crónica

INTRODUCTION: The knowledge of the relationship between exercise capacity and activities of daily living (ADLs) is important to minimize the negative outcomes in ADLs resulting from reduced exercise capacity in patients with chronic obstructive pulmonary disease (COPD). There is a limited study about the association between exercise capacity and ADLs in patients with COPD. This study aimed to investigate the relationship between maximal exercise capacity and ADLs in patients with GOLD stage II-III COPD. METHODS: Twenty-seven clinically stable GOLD stage II-III COPD patients were included (mean age = 58.59 ± 9.63 years and mean FEV1 = 50.6 ± 13.7%) in this cross-sectional study. Maximal and submaximal exercise capacity were evaluated using an incremental shuttle walk test (ISWT) and 6-min walk test (6 MWT), respectively. Activities of daily living were assessed using Glittre-ADL test. RESULTS: The ISWT distance was significantly correlated with Glittre-ADL test time (r = -0.517, p = 0.006). There was also a negative correlation between 6MWT distance and Glittre-ADL test time (r = -0.506, p = 0.007). CONCLUSION: A moderate relationship was found between maximal exercise capacity and general activities of daily living performance. The reduction in exercise capacity increases the negative influences in ADLs and strengthens our beliefs that exercise interventions in pulmonary rehabilitation could influence activities of daily living positively

INTRODUCCIÓN: Es importante conocer la relación entre la capacidad de ejercicio y las actividades de la vida diaria (ADL) para minimizar los resultados negativos de las ADL que resultan de una capacidad reducida de ejercicio en pacientes con enfermedad pulmonar obstructiva crónica (EPOC). Los estudios sobre la asociación entre la capacidad de ejercicio y las ADL en pacientes con EPOC son limitados. En este estudio se investigó la relación entre la capacidad máxima de ejercicio y las ADL en pacientes con EPOC de estadios GOLD grado II-III. MÉTODOS: Estudio transversal que incluyó a 27 pacientes clínicamente estables con EPOC de estadios GOLD grado II-III (edad media = 58.59 ± 9.63 años and FEV1 medio = 50.6 ± 13.7%). Las capacidades máxima y submáxima de ejercicio se evaluaron utilizando la prueba de lanzadera por tramos (ISWT) y la prueba de marcha de 6 minutos (6 MWT) respectivamente. Las actividades de la vida diaria se evaluaron mediante el test de Glittre-ADL. RESULTADOS: La distancia ISWT mostró una correlación significativa con el tiempo en el test Glittre-ADL (r = -0.517, p = 0.006). También se observó una correlación negativa entre la distancia en el 6MWT y el tiempo en la prueba de Glittre-ADL (r = -0.506, p = 0.007). CONCLUSIÓN: Se encontró una relación moderada entre la capacidad máxima de ejercicio y el desempeño general de las actividades de la vida diaria. La reducción en la capacidad de ejercicio aumenta las influencias negativas en las ADL y refuerza nuestras creencias de que las intervenciones con ejercicio tienen una influencia positiva en las actividades de la vida diaria en la rehabilitación pulmonar

Validity and Reliability of the Turkish Version of the London Chest Activity of Daily Living Scale in Obstructive Lung Diseases.

OBJECTIVES: The London Chest Activity of Daily Living Scale (LCADL) is a simple, useful, and comprehensive measure of dyspnea perception in activities of daily living. This study was conducted to determine the validity and reliability of the Turkish version of the LCADL. MATERIALS AND METHODS: A total of 64 patients with obstructive lung disease (24 chronic obstructive pulmonary disease, 20 asthma, and 20 bronchiectasis patients) were included. The Turkish LCADL was evaluated for interobserver reliability, test-retest reliability, and criterion validity. Two different observers applied the scale with an interval of 10 minutes to assess interobserver reliability. The second observer applied the scale twice at an interval of 10-15 days to assess test-retest reliability. Criterion validity was assessed using the 6-minute walk test (6MWT), Nottingham Health Profile (NHP), and Saint George Respiratory Questionnaire (SGRQ). RESULTS: The interobserver reliability of the scale was very high (rs=0.985, p<0.050). Cronbach's alpha coefficient for total score was 0.976 and intraclass correlation coefficient was 0.953. These results indicate that the Turkish LCADL has high reliability. The correlation between LCADL and 6MWT was moderate 0.503 (p=0.002). The LCADL total score was weakly correlated with NHP total score (rs=0.370, p=0.040) and SGRQ total score (rs=0.367, p=0.004). CONCLUSION: The Turkish version of the LCADL scale is reliable and valid in obstructive lung disease. The LCADL scale will be beneficial in existing pulmonary rehabilitation programs aiming to improve functional status. We believe that using the Turkish LCADL scale as an outcome measure in pulmonary rehabilitation programs will serve as an indicator of rehabilitation efficacy for individual patients.

Deviations of body functions and structure, activity limitations, and participation restrictions of the International Classification of Functioning, Disability, and Health model in children with cystic fibrosis and non-cystic fibrosis bronchiectasis.

BACKGROUND: To the best of our knowledge, there is no study in the literature investigating the extrapulmonary outcomes of children with non-cystic fibrosis (CF) bronchiectasis and CF under the framework of the International Classification of Functioning, Disability, and Health (ICF) model. The purpose of the present study is to evaluate the children with CF and non-CF bronchiectasis using the ICF model. MATERIALS AND METHODS: Children with CF, non-CF bronchiectasis, and healthy counterparts were evaluated (20 participants in each group) according to the ICF items in domain b (body functions), domain s (body structures), and domain d (activities and participation). The pulmonary functions, respiratory and peripheral muscle strength tests, and posture analysis were carried out for domain b. For domain d, however, the Glittre-activities of daily living test and Pediatric Outcome Data Collection were used. RESULTS: Muscle strength of shoulder abductors and hip extensors in children with CF was significantly lower than healthy children and adolescents (P < .05). The severity of lateral and posterior postural abnormalities in children with CF and non-CF bronchiectasis was higher than those of healthy children (P < .05). Among the patient groups, global function, sports/physical function, expectations, transfers/basic mobility, and pain/comfort were the most affected participation dimensions (P < .05). CONCLUSIONS: This study highlights the need for comprehensive up-to-date evaluation methods according to the ICF model for understanding rehabilitation requirements in CF and non-CF bronchiectasis in different age groups.

Physical activity of patients with bronchiectasis compared with healthy counterparts: A cross-sectional study.

BACKGROUND: A few studies have implied that patients with bronchiectasis have a more inactive lifestyle than healthy counterparts do. The main objective of this study was to compare physical activity (PA) levels subjectively and objectively between patients with bronchiectasis and healthy individuals using an accelerometer and a questionnaire. METHODS: The study included 41 patients with bronchiectasis aged 18-65 years and 35 healthy age- and sex-matched control subjects. The PA level was assessed objectively using a multisensorial PA monitor, the SenseWear Armband (SWA), and subjectively with the International Physical Activity Questionnaire (IPAQ). All participants performed the incremental shuttle walk test (ISWT) for the assessment of exercise capacity. Pulmonary function, dyspnea, severity of bronchiectasis, respiratory and peripheral muscle strength, and quality of life were assessed. RESULTS: The pulmonary function test parameters, respiratory and peripheral muscle strength, exercise capacity, step count, moderate- and vigorous-intensity PA duration were significantly lower in patients with bronchiectasis than in the healthy control group (p < 0.05). Sedentary, moderate, vigorous, and total PA duration measured using the SWA were higher than those obtained using the IPAQ (p < 0.05). CONCLUSIONS: Patients with bronchiectasis have a reduced PA level compared with healthy counterparts. The IPAQ (based on the subjective estimation of PA) outcomes differed from the SWA outcomes, reinforcing the necessity for a disease-specific PA questionnaire. IPAQ underestimates the physical activity level compared with objective measurements.

Exercise Capacity and Activities of Daily Living are Related in Patients With Chronic Obstructive Pulmonary Disease.

INTRODUCTION: The knowledge of the relationship between exercise capacity and activities of daily living (ADLs) is important to minimize the negative outcomes in ADLs resulting from reduced exercise capacity in patients with chronic obstructive pulmonary disease (COPD). There is a limited study about the association between exercise capacity and ADLs in patients with COPD. This study aimed to investigate the relationship between maximal exercise capacity and ADLs in patients with GOLD stage II-III COPD. METHODS: Twenty-seven clinically stable GOLD stage II-III COPD patients were included (mean age=58.59±9.63 years and mean FEV1=50.6±13.7%) in this cross-sectional study. Maximal and submaximal exercise capacity were evaluated using an incremental shuttle walk test (ISWT) and 6-min walk test (6MWT), respectively. Activities of daily living were assessed using Glittre-ADL test. RESULTS: The ISWT distance was significantly correlated with Glittre-ADL test time (r=-0.517, p=0.006). There was also a negative correlation between 6MWT distance and Glittre-ADL test time (r=-0.506, p=0.007). CONCLUSION: A moderate relationship was found between maximal exercise capacity and general activities of daily living performance. The reduction in exercise capacity increases the negative influences in ADLs and strengthens our beliefs that exercise interventions in pulmonary rehabilitation could influence activities of daily living positively.
