Reliability and validity of the Turkish version of the Self-care of Hypertension Inventory Version 3.0 in adults with hypertension.

BACKGROUND: Hypertension is an important cardiovascular disease risk factor. Blood pressure control for hypertensive patients is crucial to prevent hypertension related complications. Ensuring and assessing self-care of hypertensive patients is important for blood pressure control and hypertension management. The Self-care of Hypertension Inventory (SC-HI) is an inventory developed for assessing self-care of hypertensive individuals. SC-HI has three subscales; maintenance, monitoring and management. OBJECTIVE: The aim of this study was to conduct Turkish version of SC-HI Version 3.0 (SC-HI V3.0) and assessing its psychometric properties for adults with hypertension. METHODS: We included 120 hypertensive patients in this methodological study. SC-HI V3.0 translated Turkish and tested for reliability and validity. To analyse structural validity item-total correlations and factor analyses was used. Intraclass correlation coefficient (ICC) method was selected for analysing scale's consistency and convergent validity was conducted. RESULTS: The mean age of participants were 54.74 ± 7.19 years and the mean duration from hypertension diagnosis were 38.19 ± 19.42 months. Translated Turkish version's factor loadings were ranged between 0.419 and 0.841. Cronbach's alpha coefficient values were 0.661, 0.880, 0.805 and ICC values were 1.0, 0.99, 0.99 for maintenance, monitoring and management, respectively. Convergent validity's correlation coefficients weak to very strong and statistically significant. CONCLUSIONS: Turkish version of the SC-HI Version 3.0 is reliable, valid and useful scale for assessing self-management in hypertensive adults for clinical practice and research purposes.

Reliability and validity of the 6-minute pegboard and ring test for functional exercise capacity in patients with breast cancer.

BACKGROUND: Chronic pain, sensory disturbances, and lymphedema are frequent after breast cancer, leading to arm dysfunction. There is a need for objective performance-based clinical exercise tests for the upper extremity in patients with breast cancer. OBJECTIVE: The aim of this study was to evaluate the validity and reliability of the 6-minute pegboard and ring test (6PBRT) in breast cancer survivors. METHODS: Forty-eight women with breast cancer (mean age = 55.40 ± 10.40 years) were included. All patients performed 6PBRT on the first day and one week later to investigate the test-retest reliability of the 6PBRT, and intraclass correlation coefficients (ICC) were calculated. The peak workload (Wpeak) and oxygen consumption level (VO2peak) during the arm ergometer test were used as outcomes for the criterion validity of the 6PBRT. RESULTS: The 6PBRT showed good test - retest reliability with an ICC1,2 value of 0.871 [95% confidence interval (CI) 0.769-0.928]. The first 6PBRT score was very strongly correlated with the second test score (r = 0.866, p < .001). The 6PBRT score was significantly correlated with VO2peak (r = 0.634, p < .001), and Wpeak (r = 0.546, p < .001). While the 6PBRT score had less effect on VO2peak, the determination of VO2peak in the model was very good (R2 = 0.832). CONCLUSION: The 6PBRT has good test-retest reliability and is a valid test in individuals with breast cancer. These findings suggest that 6PBRT is a practical, useful, valid and reliable assessment tool for determining functional arm exercise capacity in patients with breast cancer.

Exercise capacity and muscle strength in patients who have undergone the Fontan procedure: a retrospective follow-up study.

BACKGROUND: Due to their relationship with clinical progression, follow-up of exercise capacity and muscle strength is important for optimal disease management in patients who have undergone the Fontan procedure. We aimed to retrospectively analyze exercise capacity and muscle strength trajectory over approximately 2 years. METHODS: Exercise capacity was assessed using an exercise stress test with the modified Bruce protocol on a treadmill, hand grip and knee extensor strength using a hand dynamometer, and body composition using a bioelectrical impedance device. Exercise capacity, muscle strength, and body composition follow-up data recorded between 2020 and 2022 were compared. RESULTS: Fifteen patients [median age from 17 (first assessment) to 18 years (last assessment), 5 females)] with a 20-month median follow-up time were analyzed retrospectively. There was an increase in weight, height, body mass index, and body fat weight (p<0.05). There was a tendency for increased handgrip strength (%) (p=0.069), but no significant difference was observed in the knee extensor strength of patients during the follow-up period (p>0.05). The changes in heart rate (HR) and oxygen saturation were higher in the last test than in the first test (p<0.05). Maximum HR (HRmax), % predicted HRmax and HR reserve recorded during the test and HR 1 minute after the test were similar between the first and last tests (p>0.05). CONCLUSIONS: After 20 months of follow-up, exercise capacity and muscle strength did not decline; instead, the body mass index and fat weight increased. Patients who have undergone the Fontan procedure may not be experiencing a decline in exercise capacity and muscle strength over relatively short time periods during childhood, adolescence, and early adulthood.

The Effects of Various Approaches to Lobectomies on Respiratory Muscle Strength, Diaphragm Thickness, and Exercise Capacity in Lung Cancer.

BACKGROUND: The most common surgery for non-small cell lung cancer is lobectomy, which can be performed through either thoracotomy or video-assisted thoracic surgery (VATS). Insufficient research has examined respiratory muscle function and exercise capacity in lobectomy performed using conventional thoracotomy (CT), muscle-sparing thoracotomy (MST), or VATS. This study aimed to assess and compare respiratory muscle strength, diaphragm thickness, and exercise capacity in lobectomy using CT, MST, and VATS. METHODS: The primary outcomes were changes in respiratory muscle strength, diaphragm thickness, and exercise capacity. Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) were recorded for respiratory muscle strength. The 6-min walk test (6MWT) was used to assess functional exercise capacity. Diaphragm thickness was measured using B-mode ultrasound. RESULTS: The study included 42 individuals with lung cancer who underwent lobectomy via CT (n = 14), MST (n = 14), or VATS (n = 14). Assessments were performed on the day before surgery and on postoperative day 20 (range 17-25 days). The decrease in MIP (p < 0.001), MEP (p = 0.003), 6MWT (p < 0.001) values were lower in the VATS group than in the CT group. The decrease in 6MWT distance was lower in the MST group than in the CT group (p = 0.012). No significant differences were found among the groups in terms of diaphragmatic muscle thickness (p > 0.05). CONCLUSION: The VATS technique appears superior to the CT technique in terms of preserving respiratory muscle strength and functional exercise capacity. Thoracic surgeons should refer patients to physiotherapists before lobectomy, especially patients undergoing CT. If lobectomy with VATS will be technically difficult, MST may be an option preferable to CT because of its impact on exercise capacity.

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.

Are Sleep Quality, Physical Activity Levels, and Fear of Movement of Obstructive Sleep Apnea Syndrome Patients Different From Healthy People During the Coronavirus Disease 2019 Pandemic?

OBJECTIVE: The sleep quality and physical activity levels of patients with obstructive sleep apnea syndrome during the lockdown period have not yet been investigated. The aim of this study was to evaluate the sleep quality, physical activity level, and fear of movement in patients with obstructive sleep apnea syndrome and healthy individuals during the coronavirus disease 2019 pandemic. MATERIAL AND METHODS: Patients with obstructive sleep apnea syndrome (n = 33) and healthy individuals (n = 30) were included in the study. Physical activity levels, sleep quality, and fear of movement were evaluated. RESULTS: The total physical activity amount of patients with obstructive sleep apnea syndrome and healthy individuals was lower than the acceptable levels. The obstructive sleep apnea syndrome group had significantly lower leisure-time physical activity (P = .006) and higher sitting time (P = .008) than the healthy individuals. Patients with obstructive sleep apnea syndrome had significantly more sleep disturbances, daytime dysfunction, and daytime sleepiness than healthy people (P < .001). Fear of movement was negatively correlated with the amount of vigorous (r = -0.395, P = .023) and leisure activities (r = -0.557, P = .001) in the obstructive sleep apnea syndrome group. CONCLUSION: During the coronavirus disease 2019 pandemic, patients with obstructive sleep apnea syndrome and healthy individuals had lower physical activity levels. Physical activity counseling is an important strategy for increasing the physical activity of patients with obstructive sleep apnea syndrome and healthy individuals during and after the coronavirus disease 2019 pandemic.

Validity and Reliability of the Turkish Version of the Nijmegen Questionnaire in Asthma.

OBJECTIVE: The Nijmegen Questionnaire (NQ) enables the assessment and identification of symptoms related to respiratory dysfunction and hyperventilation syndrome. The aim was to investigate the validity of the Turkish version of the NQ in asthmatics. MATERIAL AND METHODS: Fifty-four individuals with asthma were included. Spirometry was performed. Dyspnea was assessed using the modified Borg and modified Medical Research Council scales. Breath-holding time was recorded. End-tidal carbon dioxide was measured using a portable capnograph. Oxygen saturation and heart rate were recorded. Asthma Control Test was used to evaluate the asthma control level. Quality of life was assessed using the Asthma Quality of Life Questionnaire and Nottingham Health Profile. Beck Depression Inventory was used to determine depression. RESULTS: Bartlett's test of sphericity (360.749, df 105, P < .001) and Kaiser-Meyer-Olkin criterion (0.752) for 15-item NQ supported a single-factor model with 36.38% of explained variability through principal component analysis and explanatory factor analysis. For 15-item NQ with this single-factor model, Cronbach's alpha was 0.872, and the test-retest reliability was 0.628. There was a significant negative correlation between NQ and Asthma Control Test (r = -0.448), and Asthma Quality of Life Questionnaire (r = -0.743) and a significant positive association with Beck Depression Inventory (r = 0.477), Nottingham Health Profile-energy (r = 0.370), Nottingham Health Profile-pain (r = 0.313), Nottingham Health Profile-sleep (r = 0.294), and Nottingham Health Profile-physical activity scores (r = 0.406) (P < .05). CONCLUSIONS: The 15-item Turkish version of the NQ is valid and reliable in asthmatics. Individuals with uncontrolled asthma have higher NQ scores than those with well-controlled asthma. NQ is associated with asthma control level, asthma-related quality of life, health profile, and depression.

Upper Extremity Exercise Capacity and Activities of Daily Living in Individuals With Bronchiectasis Versus Healthy Controls.

OBJECTIVE: The purpose of this study was to compare the upper extremity exercise capacity and activities of daily living (ADL) in individuals with bronchiectasis and controls. METHODS: Twenty-four individuals with bronchiectasis and 24 healthy controls were assessed for upper extremity exercise capacity (6-minute pegboard and ring test [6PBRT]) and ADL (Glittre ADL test). Energy expenditure was measured using a wearable metabolic monitor during the Glittre ADL test. RESULTS: The mean [SD] 6PBRT score of individuals with bronchiectasis was significantly lower than the mean score of controls (196.50 [51.75] vs 243.00 [29.76] number of rings). The Glittre ADL test duration was significantly higher in individuals with bronchiectasis compared with controls (3.54 [1.53] vs 2.36 [0.18] minutes), despite similar energy expenditure during the Glittre ADL test between the groups (17.67 [5.28] kcal in individuals with bronchiectasis vs 18.13 [5.71] kcal in controls). The 6PBRT score and the Glittre ADL test duration were negatively correlated in individuals with bronchiectasis (r = -0.694). CONCLUSION: The individuals with bronchiectasis had reduced upper extremity exercise capacity compared with healthy controls. Energy expenditure during ADL was similar between individuals with bronchiectasis and healthy controls, despite lower ADL performance in individuals with bronchiectasis. The upper extremity exercise capacity and ADL are related in individuals with bronchiectasis. Given this relationship, inclusion of upper extremity exercise training in pulmonary rehabilitation programs should be considered. IMPACT: Considering the impairment of upper extremity exercise capacity and ADL in individuals with bronchiectasis highlights the need to tailor preventive strategies and preclude further unfavorable effects. LAY SUMMARY: Bronchiectasis may reduce exercise capacity in your arms and reduce your ability to perform daily living activities. Physical therapists can evaluate your condition and create rehabilitation programs to help manage these impairments.

Assessment of exercise capacity using field walking tests in patients after the Fontan procedure: A case-control study.

BACKGROUND: Despite the frequent use of the 6-minute walk test (6MWT), exercise capacity has not been assessed with the incremental shuttle walk test (ISWT) in patients who have undergone the Fontan procedure. It is unclear whether these tests cause clinically relevant cardiorespiratory responses in these patients. OBJECTIVES: We aimed to assess cardiorespiratory responses to the 6MWT and ISWT in Fontan patients, compare the responses with those in the controls, and examine the agreement between the two field tests. METHODS: Submaximal exercise capacity was assessed using the 6MWT, maximal exercise capacity using the ISWT, quadriceps isometric muscle strength with a hand dynamometer, and body composition using a bioelectrical impedance device. RESULTS: Twenty-one Fontan patients (16.42±6.63 years, 5F/16M) and 21 controls (16.57±4.30 years, 7F/14M) were included. While body composition was similar between the groups (p>0.05), quadriceps isometric muscle strength and 6MWT and ISWT distance were lower in the Fontan patients than in the controls (p<0.05). In both the 6MWT and ISWT, pre- and post-test heart rate (HR), oxygen saturation (SpO2), dyspnea, and leg fatigue differed significantly between the Fontan patients and the controls (p<0.05). In addition, the ISWT resulted in a more significant change in HR, SpO2, and leg fatigue than the 6MWT in the Fontan patients (p<0.05). Bland-Altman plots for the 6MWT vs. the ISWT indicated agreement between the two tests. CONCLUSION: There were remarkable changes in HR, SpO2, dyspnea, and leg fatigue in both tests. With similar safety to the 6MWT but with more caution applied for adverse events, the ISWT can also be performed as a field test to evaluate exercise capacity and identify more pronounced exercise-induced responses (especially oxygen desaturation) in Fontan patients.

Is there a relationship between respiratory function and trunk control and functional mobility in patients with relapsing-remitting multiple sclerosis?

OBJECTIVE: Multiple sclerosis (MS) causes impairment of respiratory function, trunk control, and functional mobility. The purpose of this study was to investigate the relationship between functional mobility and respiratory function and trunk control in MS patients and to compare the findings with those in healthy individuals. METHODS: Thirty MS patients and 30 healthy subjects were included in this case-control study. All participants were evaluated with a pulmonary function test, maximal inspiratory and expiratory pressure (MIP, MEP), core stability tests, a lumbopelvic stability test (LST), a 2-minute walk test (2MWT), and the Timed Up and Go test (TUG). The disability level of the MS patients was assessed with the Expanded Disability Status Scale (EDSS). RESULTS: Respiratory function, respiratory muscle strength, trunk control, and functional mobility were lower in the MS patients than in the controls (p < 0.05). TUG values had a significant negative correlation and the 2MWT values had a significant positive correlation with MEP, core stability tests, and the LST (p < 0.05). Of the variance in the 2MWT distance, 69% was explained by the LST, EDSS, and MEP; of the variance in TUG time, 40% was explained by the EDSS and MEP (p < 0.05). CONCLUSIONS: To preserve and develop functional mobility in MS patients, approaches to increase respiratory function and trunk control should be included in rehabilitation programs.

Gait and functional balance in non-CF bronchiectasis.

BACKGROUND: The decline in ambulatory activities and negative alterations in gait characteristics may impair balance and increase fall risk in obstructive lung diseases. Few studies have evaluated balance and gait parameters in individuals with bronchiectasis. PURPOSE: This study aimed to compare the gait parameters and functional balance in individuals with non-cystic fibrosis (CF) bronchiectasis and healthy subjects. METHODS: This cross-sectional and retrospective study analyzed data from 22 individuals with non-CF bronchiectasis and 32 healthy controls recorded between July 2019 and July 2020. Functional balance was assessed using the Timed Up and Go (TUG) test. Gait parameters were evaluated using the Biodex Gait Trainer. Step cycle (s), gait speed (m/s), the number of steps per minute, and ambulation index were measured for 6 min.Results The TUG time (s) was significantly longer (p = .019, effect size = 0.66), and gait speed (m/s) (p ˂ 0.001, effect size = 2.47), step cycle (s) (p ˂ 0.001, effect size = 2.23), and ambulation index (p ˂ 0.001, effect size = 2.56) were significantly reduced in individuals with non-CF bronchiectasis compared with healthy controls. CONCLUSION: Non-CF bronchiectasis is related to unfavorable changes in gait characteristics, such as slower gait speed and the decreased average step cycle. In addition, impairment in functional balance and mobility exists in a small percentage of adults with non-CF bronchiectasis. In comprehensive pulmonary rehabilitation, balance and gait evaluations should be included to prevent falls in adults with non-CF bronchiectasis.

Body functions and structure, activity, and participation limitations of adult cystic fibrosis patients under the international classification of functioning, disability, and health framework.

Objective: There is no study in the literature evaluating impairments and functional limitations in adults with cystic fibrosis (CF) under the framework of the International Classification of Functioning, Disability, and Health (ICF). To evaluate the adults with CF using ICF model. Methods: Twenty-three adults with CF and 23 age-sex matched healthy individuals included in this cross-sectional study. The participants evaluated according to the selected items for domain b, domain s, and domain d from the Obstructive Pulmonary Diseases (OPD) Comprehensive Core Set. The body composition, pulmonary functions, respiratory and peripheral muscle strength/endurance tests and anxiety/depression level were evaluated for domain b and s. For domain d, the Incremental Shuttle Walk Test (ISWT) and Short Form-36 (SF-36) Health Survey were used. Results: The fat-free mass (p = .044), pulmonary functions (p < .05), respiratory muscle endurance (p = .010), absolute and %quadriceps muscle strength (p = .001, p = .025, respectively), number of sit-ups (p = .020), walking speed (p = .035), ISWT and ISWT% distance (p < .001) and peak oxygen consumption (p < .001) were significantly lower in adults with CF compared to healthy individuals (p < .05). There were only significant differences in SF-36 physical functioning and role physical subdimension scores between groups (p = .009, p = .045 respectively). Conclusions: The ICF framework is applicable to comprehensively evaluate limitations of adults with CF among rehabilitation professionals. Especially age, respiratory function, respiratory muscle strength and endurance, dyspnea perception, peripheral muscle endurance were related to activity and participation limitation.

Reliability and Validity of the Turkish Version of the Performance Measure for Activities of Daily Living-8 for Patients with Mild Symptomatic Heart Failure.

OBJECTIVE: The Performance Measure for Activities of Daily Living-8 (PMADL-8) for patients with congestive heart failure is an International Classification of Functioning, Disability, and Health-based Activities of Daily Living (ICF) questionnaire to evaluate disease-specific functional limitations in chronic heart failure (CHF). The purpose of this study was to investigate the reliability and validity of the Turkish version of the PMADL-8 in CHF patients. METHODS: In this study, 50 patients with CHF were included. Test-retest reliability of the PMADL-8 was assessed by intraclass correlation coefficient and Cronbach's alpha was calculated for internal consistency. Correlation coefficients between the PMADL-8 and New York Heart Association (NYHA) functional class, Chronic Heart Failure Questionnaire (CHQ), Nottingham Health Profile (NHP) were analyzed for construct validity. RESULTS: The Cronbach's alpha value of the PMADL-8 test and retest scores were recorded as 0.996, indicating that the scale is highly reliable. Test-retest reliability results of the PMADL-8 (mean intraclass correlation coefficient = 0.996) were excellent. The PMADL-8 score was moderately correlated with the NHP total score (r = 0.629, P < .001) and NHP physical abilities score (r = 0.517, P < .001). The PMADL-8 score was weakly correlated with the NYHA functional class (r = 0.385, P < .006), CHQ dyspnea (r = -0.475, P < .001), CHQ fatigue (r = -0.340, P = .016), and total score (r = -0.367, P = .009). CONCLUSION: The Turkish version of PMADL-8 is a reliable and valid assessment tool that could be used to determine activity limitations in CHF. The PMADL-8 is also useful for health professionals during the ICF evaluation of CHF patients.

Body Function and Structure, Activity, and Participation Limitations of Lung Transplant Recipients Within the Scope of the International Classification of Functioning, Disability, and Health.

OBJECTIVES: There is no study in the literature that specifically evaluates lung transplant recipients in the long-term under the framework of the International Classification of Functioning, Disability, and Health. The aim of this study was to evaluate the relationships between lung transplant recipient age, age at transplant, and comorbidity levels and the body structure and functions and the activity and participation levels of patients within the scope of the International Classification of Functioning, Disability, and Health. MATERIALS AND METHODS: We evaluated 27 lung transplant recipients according to the International Classification of Functioning, Disability, and Health items in domain b (body functions), domain s (body structures), and domain d (activities and participation). For domain b, sleep functions, psychosocial status, respiratory functions, and upper and lower extremity exercise capacity were evaluated. Posture was evaluated for the s domain. Balance, arm functional capacity, health-related quality of life, and physical activity were evaluated for domain d. RESULTS: As the age of lung transplant recipients and the age at transplant increase, their sleep quality and respiratory functions decreased, and postural impairment increased. There was a negative correlation between age at transplant and functional exercise capacity (P < .05). As the comorbidity level of the recipient increases, the upper and lower extremity exercise capacity, physical activity level, and quality of life declined. There was a moderately positive correlation between the level of comorbidity and balance disorder (P < .05). CONCLUSIONS: We found the International Classification of Functioning, Disability, and Health framework to be useful for the evaluation and for planning pulmonary rehabilitation for lung transplant recipients; it can bring a new perspective to physiotherapists specialized in cardiopulmonary rehabilitation.

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.

Exercise performance in children and adolescents with cystic fibrosis with and without abnormal glucose tolerance: a single center cross-sectional study.

BACKGROUND: Abnormal glucose tolerance (AGT) in cystic fibrosis (CF) affects lung function and clinical parameters, including aerobic fitness. However, its effects on physical activity level (PAL), anaerobic power (AP), and muscle strength (MS) in children and adolescents are unknown. PURPOSE: To investigate aerobic fitness, PAL, AP, and MS in pediatric patients with mild-to-moderate CF and AGT. METHODS: The study included children and adolescents with CF aged 10-18 years. Participants underwent a pulmonary function test, quadriceps, and handgrip MS measurement, vertical jump test to assess AP, and six-minute walk test (6MWT) to assess aerobic fitness. Bouchard's Three-Day Physical Activity record was used to determine PAL. RESULTS: Height z-score (p = .006), 6MWT (p = .024), handgrip (p = .028), quadriceps MS (p = .044), and AP (p = .036) were significantly lower in AGT (n = 21) than normal glucose tolerance (NGT) (n = 19). In the AGT group, glycosylated hemoglobin (HbA1c) was significantly associated with forced expiratory volume in one second (FEV1) (p = .046). 6MWT distance (6MWD) was associated with height (p = .008), FEV1 (p = .001), forced vital capacity (FVC) (p = .001), forced expiratory flow from 25% to 75% (FEF25-75%) (p = .030), handgrip MS (p = .012), and PAL (p = .034). After adjusting for height and FEV1, the groups had similar 6MWD, MS, and AP (p > .05); also, insulin was associated with MS and AP but not with 6MWT or quadriceps MS. CONCLUSION: Measures of aerobic fitness, MS, and AP are lower in AGT, but after adjusting for height and FEV1, aerobic fitness, MS, and AP do not show substantial differences. Insulin sensitivity and resistance are associated with MS and AP.

Active video gaming in primary ciliary dyskinesia: a randomized controlled trial.

Primary ciliary dyskinesia (PCD) impairs pulmonary function, respiratory and peripheral muscle strength, and exercise capacity. We aimed to investigate the effects of active video games (AVGs) on pulmonary function, respiratory and peripheral muscle strength, exercise capacity, muscle oxygenation (SMO2), physical activity, activities of daily living (ADL), and quality of life (QOL) in PCD. Thirty-two PCD patients were randomly assigned to AVG group (n = 16) and the control group (n = 16). AVG group underwent AVGs using Xbox-Kinect-360 device for 40 min/day, 3 days/week for 8 weeks plus airway clearance techniques (ACT), and the control group was applied ACT only. Pulmonary function, respiratory and quadriceps muscle strength, exercise capacity (6-min walk test [6MWT], incremental shuttle walk test [ISWT]), and ADL (Glittre ADL test) were assessed. SMO2 during ISWT and ADL test was also recorded. Physical activity and QOL (PCD-QOL) were evaluated. Pulmonary function; respiratory and quadriceps muscle strength; 6MWT and ISWT distance; physical activity; ADL performance; SMO2; physical, emotional, and social functioning; treatment burden; and upper and lower symptom parameters of PCD-QOL significantly improved after 8 weeks in the AVG group (p < 0.05). There were no significant differences in measured parameters except emotional function and upper respiratory symptom scores of PCD-QOL in the control group (p > 0.05).    Conclusion: The AVGs positively affect pulmonary (pulmonary function, respiratory muscle strength) and extrapulmonary (peripheral muscle strength, exercise capacity, SMO2, physical activity, ADL, and QOL) characteristics in children with PCD. The AVGs may be added to the pulmonary rehabilitation program as an exercise training modality in patients with PCD.   Trial registration: This study registered at ClinicalTrials.gov with NCT03832491 on February 6, 2019. What is Known: • It is indicated that exercise capacity is increased with traditional exercise-training in a case report of Kartagener Syndrome. What is New: • No randomized controlled study investigated the effects of exercise-training in PCD. • 8-week moderate-intensity active video gaming (AVGs) improves pulmonary and extrapulmonary features in children with PCD. AVGs may be preferable due to being enjoyable, providing visual and audial feedback in the pulmonary rehabilitation programs of PCD.

Health related behaviours and physical activity level of hypertensive individuals during COVID-19 pandemic.

During the COVID-19 pandemic, all countries implemented lockdown to prevent transmission of coronavirus. The prolonged stay-at-home process created some unfavourable effects like unhealthy lifestyle, physical inactivity and sedentary behaviour especially in patients with cardiovascular risk. Hypertensive individuals are also affected in the pandemic because of limited access to healthcare services, screening, and altered lifestyles. We aimed to investigate physical activity (PA) level, sedentary behaviour, mental health and healthy lifestyle behaviours in patients with hypertension and compare these parameters with healthy controls. This prospective, cross-sectional study included 40 hypertensive and 40 age-sex matched healthy controls. We assessed PA with the International Physical Activity Questionnaire long-form, quality of life with Short-Form 36 (SF-36) questionnaire, anxiety and depression with Hospital Anxiety and Depression Scale (HADS) and lifestyle behaviours with Health-Promoting Lifestyle Profile Scale-II (HPLP-II). Moderate and vigorous PA levels of hypertensives' were statistically lower than healthy controls (P = 0.001; P = 0.003, respectively). Hypertensive patients exhibited lower SF-36 physical function (P = 0.001), energy/vitality (P = 0.042), body pain scores than those of healthy controls (P = 0.007). Although HADS-anxiety, depression scores were similar (P > 0.05), the depression ratio (45%) was more common in the hypertensive group during the lockdown. The main findings are that hypertensive patients have lower PA levels and worse quality of life than healthy controls during the pandemic. In addition, the presence of depression is more common among hypertensive patients. Considering unhealthy lifestyles, governments, and health professionals should take some precautions and plan interventions against physical inactivity. As known, providing regular physical activity is a keystone to fighting against cardiovascular disease.

Impaired Balance and Gait Characteristics in Patients With Chronic Heart Failure.

BACKGROUND AND AIMS: Heart failure affects most systems of the body and causes various problems in patients. Balance deficits and gait deviations can be a result of these effects. There is little information in the literature about balance and gait parameters in chronic heart failure (CHF). This study aimed to investigate balance abnormalities together with gait deficits for possible associations in patients with CHF and compare them to healthy controls. METHODS: Twenty-two (22) patients with CHF (59±2.5 years) and 22 age- and gender-matched healthy subjects (59.4±6.8 years) participated in the study. This study is a cross-sectional/comparison study. Balance was evaluated using the Activity-Specific Balance Confidence Scale (ABC) and the Mini-Balance Evaluation Systems Test (Mini-BESTest) balance battery, which includes the timed up-and-go test (TUG) and dual-task TUG. Gait analysis was performed using a Biodex Gait Trainer. Peripheral muscle strength (quadriceps muscle and handgrip strength) was assessed using a hand dynamometer and exercise capacity using the six-minute walk test (6MWT). RESULTS: The CHF patients had significantly lower Mini-BESTest total, reactive postural control, and gait stability scores, significantly longer TUG/dual-task TUG time, and lower ABC score compared to the healthy control group (p<0.05). Chronic heart failure patients also showed significantly lower gait speed, stride length, gait cycle and step length (p<0.05). Dominant-side quadriceps muscle and handgrip strength and 6MWT distance were significantly reduced in CHF (p<0.05). Anticipatory postural adjustments and sensory orientation did not differ between groups. CONCLUSIONS: Our study demonstrated impaired balance and gait performance and reduced muscle strength and exercise capacity in patients with CHF. Cardiac rehabilitation including balance and walking training should be planned for CHF patients to eliminate balance disorders, gait impairment and prevent falls in this patient group.
