RESUMEN
BACKGROUND AND OBJECTIVE: There are few studies that have used inspiratory muscle training (IMT) as an intervention for patients with isolated idiopathic pulmonary fibrosis (IPF). This study aimed to investigate and interpret the effects of home-based telerehabilitation-assisted IMT in patients with IPF. METHODS: Twenty-eight participants with IPF took part in the study. Lung function tests, functional exercise capacity by 6-min walk distance (6MWD), dyspnoea perception by modified medical research council dyspnoea scale (mMRC), and inspiratory muscle strength by maximal inspiratory pressure (MIP) were assessed. IMT was performed twice a day, 7 days/week, for 8 weeks. The intervention group (n = 14) performed IMT at 50% of their baseline MIP while the control group (n = 14) performed IMT without applied resistance. Loading intensity was progressed by keeping the load at 4-6 on a modified Borg scale for the highest tolerable perceived respiratory effort for each patient. RESULTS: Dyspnoea based on mMRC score (p < 0.001, η2 effect size = 0.48) significantly decreased within the intervention group compared with the control group. There were significant increases in the intervention group compared to the control group based on 6MWD (p < 0.001, η2 effect size = 0.43), MIP (p = 0.006, η2 effect size = 0.25) and MIP % predicted (p = 0.008, η2 effect size = 0.25). CONCLUSION: The findings of this study suggest that an 8-week home-based telerehabilitation-assisted IMT intervention produced improvements in inspiratory muscle strength, leading to improvements in functional exercise capacity and dyspnoea.
RESUMEN
BACKGROUND: While a whole-body warm-up may not adequately prepare the inspiratory muscles for exercise, inspiratory warm-up is an effective approach in preparing the inspiratory muscles for exertion. OBJECTIVES: To investigate the effects of inspiratory muscle warm-up performed prior to inspiratory muscle training (IMT) during pulmonary rehabilitation (PR) in patients with moderate-to-severe chronic obstructive pulmonary disease (COPD) and inspiratory muscle weakness. METHODS: Pulmonary function tests, maximal inspiratory and expiratory pressures (MIP and MEP), 6-minute walk test distance (6MWD), modified Medical Research Council Dyspnea Scale(mMRC), St. George's respiratory questionnaire and the 36-item short-form health survey were evaluated. Both groups performed IMT during PR for 8 weeks. The warm-up group (n = 15), in addition to the standard IMT group (n = 15), performed an inspiratory muscle warm-up protocol before each IMT session. RESULTS: At the end of the 8-week intervention, improvements in dyspnea (mMRC in score, p =0.033, effect size =0.76); exercise capacity (6MWD in meters, p =0.001, effect size =1.30); pulmonary function [forced expiratory volume in 1 second (FEV1) in %predicted, p =0.006, effect size =1.10]; and inspiratory muscle strength (MIP in cmH2O, p =0.001, effect siz e = 1.35) were significantly greater in the warm-up group. Moreover, there were significant improvements in health-related quality of life (HRQoL) sub-scores after the training in both groups (p <0.05). CONCLUSIONS: This study demonstrated improvements in both groups, surpassing or closely approaching the established minimal clinically important difference values for the respective outcomes. Performing a warm-up for inspiratory muscles before IMT boosts benefits for pulmonary function, inspiratory muscle strength, exercise capacity, dyspnea, and HRQoL in subjects with moderate-to-severe COPD and inspiratory muscle weakness.
RESUMEN
Kinesiophobia is a well-known barrier to positive clinical outcomes among patients with various diseases, but there remain few comprehensive studies of kinesiophobia among patients with myocardial infarction (MI). In this cross-sectional study, we investigated the presence of kinesiophobia and its relationship with clinical outcomes among 42 patients with MI who completed the Tampa Scale of Kinesiophobia Swedish Version for Heart (TSK-SV Heart) the International Physical Activity Questionnaire-Short Form (IPAQ-SF), the Six-Minute Walk Test (6MWT), the Hospital Anxiety and Depression Scale (HADS), the modified Medical Research Council (mMRC) Dyspnea Scale, the Charlson Comorbidity Index (CCI), and the MacNew Heart Disease Health-Related Quality of Life Questionnaire. The participants' mean TSK-SV Heart score was 39.24 (SD = 6.65), and 71.4% of these patients reported a high level of kinesiophobia. The TSK-SV Heart score demonstrated a strong correlation with the IPAQ-SF, 6MWT walking distance, and mMRC score (p < .001), and a moderate correlation with the HADS, CCI, and MacNew Heart Disease HRQoL (p < .05). Patients with a high level of kinesiophobia had lower IPAQ-SF, 6MWT walking distance, and HRQoL and higher mMRC, CCI, and HADS scores than patients with low levels of kinesiophobia (p < .05). Kinesiophobia was common and represented a considerable risk factor for physical-psychosocial dysfunctions in these patients with MI. To maintain functional independence and to increase physical activity level, clinicians should consider kinesiophobia from early to late-stage disease and should add a treatment focus that seeks to eliminate kinesiophobia in cardiac rehabilitation programs.

OBJECTIVE: Dyspnea may be a debilitating factor for people with pulmonary problems as it may cause fear of movement. The aim of the present study was to determine the related factors with breathlessness beliefs, in other words, dyspnea-related fear of movement, in patients with chronic obstructive pulmonary disease. MATERIAL AND METHODS: Male patients with chronic obstructive pulmonary disease were included in the study. Breathlessness beliefs (Breathlessness Belief Questionnaire), perceived dyspnea severity (modified Medical Research Council Dyspnea Scale and modified Borg Scale), pulmonary function tests (forced vital capacity, forced expiration volume in 1 second, and peak expiratory flow), emotional status (Hospital Anxiety and Depression Scale), fatigue (Fatigue Impact Scale and Fatigue Severity Scale), physical activity level (International Physical Activity Questionnaire-Short Form), disease-related quality of life (St. George Respiratory Questionnaire), and generic quality of life (Short-Form 36) were evaluated. RESULTS: A total of 70 patients were included. Significant correlations were detected between breathlessness beliefs and perceived dyspnea severity, pulmonary function tests, emotional status, fatigue, physical activity level, disease-related quality of life, and generic quality of life (P < .001). No correlations were detected between physical characteristics and dyspnea-related fear of movement (P > .05). CONCLUSION: Dyspnea-related fear of movement was found to be strongly related to perceived dyspnea severity, pulmonary function tests, emotional status, fatigue, physical activity level, and quality of life; thus, including breathlessness beliefs assessment into clinical examination may help clinicians to understand their patients' needs comprehensively.
RESUMEN
BACKGROUND AND AIM: New parameters in the 6-minute walk test (6MWT) are needed for assessing exercise capacity in patients with idiopathic pulmonary fibrosis (IPF). To our knowledge, no previous study has investigated the potential of using the desaturation distance ratio (DDR) to assess exercise capacity specifically in patients with IPF. This study aimed to investigate whether DDR is a potential tool for assessing the exercise capacity of patients with IPF. METHODS: This study conducted with 33 subjects with IPF. Pulmonary function tests and a 6MWT were performed. To calculate the DDR, first, the difference between the patient's SpO2 at each minute and the SpO2 of 100% was summed together to determine the desaturation area (DA). Next, DDR was calculated using dividing DA by the 6-minute walk test distance (6MWD) (i.e., DA/6MWD). RESULTS: When correlations of 6MWD and DDR with changes (Δ) in the severity of perceived dyspnea were examined, 6MWD did not significantly correlate with ΔBorg. Conversely, there was a significant correlation between the DDR and ΔBorg (r= 0.488, p=0.004). There were significant correlations between 6MWD and FVC % (r=0.370, p=0.034), and FEV1 % (r=0.465, p=0.006). However, DDR was significantly more correlated with FVC % (r= -0.621, p< 0.001), FEV1 % (r= -0.648, p< 0.001). Moreover, there was a significant correlation between DDR and DLCO % (r= -0.342, p=0.052). CONCLUSIONS: The findings of this study suggest that DDR is a promising and more useful parameter for assessing patients with IPF.
RESUMEN
BACKGROUND: Diaphragmatic function can be affected in many diseases and disorders. Although systemic sclerosis (SSc) is a serious connective tissue disease that affects not only the skin but also the pulmonary and musculoskeletal systems, there is insufficient information about diaphragm function. AIMS: To compare the diaphragmatic parameters by ultrasonography (USG) in patients with SSc and healthy individuals and examine the relationship between these parameters and clinical features in patients with SSc. METHODS: This study included 13 patients with SSc and 15 healthy individuals. Muscle thickness (in deep inspiration Tins and at the end of calm expiration Texp), changes in thickness (∆T), and thickening fraction at deep breathing were evaluated by USG. Skin thickness, pulmonary function tests, respiratory muscle strength, and the perception of dyspnea were measured as clinical features. RESULTS: The results of Texp, Tins, and ∆T were similar in both groups (pâ¯> 0.05), albeit patients in the SSc group had less thickening fraction compared to the control group (79.9⯱ 36.7â¯cm and 103.8⯱ 20.6â¯cm, respectively, pâ¯< 0.05). The Tins, ∆T, and thickening fraction of the diaphragm were associated with skin thickness, pulmonary function test parameters, and respiratory muscle strength (pâ¯< 0.05). Besides, there was significant correlation between muscle thickening fraction and perception of dyspnea (pâ¯< 0.05). CONCLUSION: These results confirm that diaphragm thickness and contractility can be affected in patients with SSc. Therefore, ultrasonographic evaluation of the diaphragm can play a complementary role to pulmonary function test and respiratory muscle strength measurement in the diagnosis and follow-up of patients with SSc.

BACKGROUND: The globalization of healthcare systems, and the aim to lower healthcare costs have all contributed to the growth of telehealth technology in recent years. However, before these systems are put into use, their efficacy should be verified. To the best of our knowledge, this is the first study focusing on the evaluation of functional exercise capacity using the 30-s sit-to-stand (30-s STS) test as a tele-assessment method in patients with type 2 diabetes mellitus (T2DM). AIMS: The purpose of the study is to investigate the level of agreement between tele-assessment and face-to-face assessment of 30-s STS test in patients with T2DM. METHODS: Fifty participants performed two times 30-s STS tests separated by 1 h: a face-to-face and an Internet-connected video call examination (tele-assessment). Two physiotherapists conduct these evaluations; each was blinded to the other. The order of the evaluations was designated at random for each participant and physiotherapist. RESULTS: There was a good level of agreement between tele-assessment and face-to-face assessment of the 30-s STS test (mean differences = 0.20 ± 0.88, limits of agreement = 1.93 to - 1.53). Excellent interrater reliability was found for scores of the 30-s STS test [ICC = 0.93 (95% CI: 0.88; 0.96)]. In addition, all before and after test parameters show that there was a very good interrater reliability (ρ ≥ 0.75). CONCLUSIONS: This study shows a good level of agreement between tele-assessment and face-to-face assessment of the 30-s STS test. Our study's findings indicate that tele-assessment is a potential application to determine the level of physical capacity remotely in patients with T2DM.

BACKGROUND: Patients with systemic sclerosis (SSc) are at high risk for pulmonary and vascular complications. Smoking is an important risk factor for respiratory symptoms and vascular complications of many diseases in the general population. However, studies on the role of smoking in SSc are insufficient. AIMS: This study aimed to compare pulmonary function, respiratory symptoms, functional level, and health-related quality of life (HRQoL) in patients with SSc according to smoking status and to assess the correlation between cigarette consumption and these parameters in patients with SSc. METHODS: Seventy-two patients with SSc (smoker group; n = 35 or nonsmoker group; n = 37) were included. The pulmonary function test was measured with a spirometer. Respiratory symptoms were questioned and the perceived severity of dyspnea and fatigue was evaluated. The functional levels were determined by questioning the patients' average daily walking distance, exercise habits, and daily sedentary time. HRQoL was assessed by Scleroderma Health Assessment Questionnaire. RESULTS: The rate of respiratory symptoms including dyspnea, cough, and sputum were higher in the smoker group (p < .001, p = .041, and p < .001, respectively). Also, the perceived severity of dyspnea and fatigue was higher in the smoker group (p < .05). The mean daily walking distance, exercise habits, and overall HRQoL were lower (p = .004, p = .002, and p = .034, respectively) and the sedentary time and vascular complications were higher (p < .001 and p = .038, respectively) in the smoker group. However, there was no significant difference between the two groups in terms of the pulmonary function test (p > .05). There was a weak to moderate correlation between cigarette consumption and respiratory symptoms, dyspnea and fatigue severity, functional level, and HRQoL in the smoker group (0.001 ≤ p ≤ .024). CONCLUSIONS: Smoking may increase respiratory symptoms and vascular complications and decrease the functional level and HRQoL in patients with SSc. To maintain functional independence in patients with SSc, awareness of the harms of smoking should be increased and smoking cessation should be encouraged, along with physiotherapy and rehabilitation programs including exercise and physical activity recommendations.
RESUMEN
The importance of using masks during exercise has increased since the coronavirus disease-2019 (COVID-19). This study aimed to investigate the effects of using surgical masks on gas exchange and exercise responses in maximal exercise. Twenty-six participants were included. Participants performed the maximal exercise tests twice, masked, and unmasked. Gas exchange parameters (at maximal exercise and anaerobic threshold [AT]) and hemodynamic responses were measured. In the hemodynamic responses measured at rest, only the saturation of peripheral oxygen (SpO2 ) was lower in the masked (mean: 97.23 ± 1.33%) measurement than in the unmasked (mean: 97.96 ± 1.07%) measurement (p = 0.006). Test duration was lower in the masked test (unmasked: 10.32 ± 1.36 min vs. masked: 10.03 ± 1.42 min, p = 0.030). Peak oxygen consumption (VO2peak ) (unmasked: 31.23 ± 5.37 vs. masked: 27.03 ± 6.46 ml/kg/min), minute ventilation (VE ) l/min, and energy expenditure (EE) kcal/hour were higher in unmasked tests (p < 0.001). There was no difference in the gas exchange parameters measured at the AT in the masked and unmasked tests (p > 0.05). Respiratory gas exchange parameters were affected in peak exercise due to increased respiratory workload, but not at the AT. There was no change in hemodynamic responses because vascular control may not be affected by mask usage.

BACKGROUND: Supervised high-intensity interval training (HIIT) has been proposed to be more effective than moderate-intensity continuous training (MICT) for improving exercise capacity, but there are not sufficient information effects of home-based HIIT and MICT in patients with myocardial infarction (MI). AIMS: To compare the effects of home-based HIIT and MICT in patients with MI. METHODS: Twenty-one patients with MI were randomly assigned to one of two home-based exercise modes: HIIT group and MICT group. Home-based HIIT and MICT were performed twice a week for 12 weeks with an exercise intensity of 85-95% of heart rate (HR) reserve and 70-75% HR reserve, respectively. The primary outcome measure was functional capacity. Secondary outcomes included resting blood pressure and HR, peripheral oxygen saturation, pulmonary function and respiratory muscle strength, dyspnea severity, body composition (body fat%, body mass index (BMI), fat free muscle), peripheral muscle strength, and health-related quality of life (HRQoL). RESULTS: Functional capacity, measured by 6-minute walk test, increased in HIIT and MICT group (p < 0.05). Resting BP and HR, body fat%, and BMI were significantly decreased, and pulmonary functions, respiratory-peripheral muscle strength, and HRQoL were significantly increased in the both groups (p < 0.05). Home-based HIIT was more effective than MICT in improving pulmonary functions and lower extremity muscle strength (p < 0.05). CONCLUSIONS: This study suggests that HIIT and MICT can be applied at home-based in patients with MI and play an important role in improving functional capacity, health outcomes, and HRQoL. TRIAL REGISTRATION: Clinical Trials Number: NCT04407624.

BACKGROUND: Surgical masks have become an important accessory of physical activity in daily life due to the COVID-19 pandemic. AIMS: To determine the effects of the surgical mask on respiratory gas exchange parameters, dyspnoea, and hemodynamic responses during maximal exercise in different age groups and gender. METHODS: Twenty-six healthy participants between 18 and 65 years (mean 37.35 ± 15.99) performed a maximal exercise test twice randomly, with and without a mask. To determine the respiratory gas exchange parameters (peak oxygen consumption (VO2peak), minute ventilation (VE), energy expenditure (EE), respiratory rate), and hemodynamic responses, each participant underwent a maximal exercise test with Bruce protocol on the treadmill. The modified Borg scale (MBS) was used to determine the dyspnoea before and after exercise test. RESULTS: Test duration (min), metabolic equivalents (MET), VO2peak ml/kg/min, respiratory rate, and peak heart rate (HRpeak) of young participants after exercise test with and without a mask were higher than in middle-aged participants (p < 0.01). There was no significant difference between males and females in test duration, VO2peak ml/kg/min, VO2peak ml/min, MET, VE l/min, respiratory rate, MBS, and EE in masked tests (p > 0.05). CONCLUSION: The surgical mask use affected the maximal exercise capacity of middle-aged participants more than young participants. Although males performed better than females in tests without masks, the decrease in exercise capacity with mask use was greater than in females. Advanced age and male gender may be factors that need more attention during exercise with mask use. TRIAL REGISTRATION NUMBER AND DATE: NCT04498546-02/17/2021.

PURPOSE: Obstructive sleep apnea (OSA) is an important public health problem. Beyond common treatment options, solution-oriented options are needed. Oropharyngeal exercise training may be a research area in this respect. This study aimed to evaluate the effects of oropharyngeal exercise (OPE) in addition to continuous positive airway pressure (CPAP) therapy in patients diagnosed with OSA. METHODS: Patients with moderate and severe OSA were screened from the electronic database of our hospital and 41 patients (20: exercise group; 21: control group) were included in the study. Each patient was assessed with CPAP usage time, maximal voluntary ventilation (MVV), maximum inspiratory and expiratory pressure (MIP-MEP), neck circumference, body mass index (BMI), waist-hip ratio, Epworth sleepiness score, Pittsburgh sleep quality index (PSQI), and short-form health survey (SF-36) in the first visit. The OPE was prescribed in addition to CPAP for the exercise group and performed by the patients for 3 months. At the end of the third month, groups were re-assessed with the same parameters. RESULTS: Most of the patients were men, and the mean age of the study population was 51.9 ± 7.4; the mean apnea-hypopnea index (AHI) in the last polysomnography report was 53.3 ± 27.4. In the exercise group, MVV (p = 0.003), MIP (p = 0.002), MEP (p = 0.024), and SF-36 energy/fatigue (p = 0.020) were observed to increase while the total PSQI score (p = 0.036) decreased. The neck circumference (p = 0.006) and BMI (p = 0.013) were found to be significantly decreased in the exercise group. CONCLUSIONS: We found that OPE training may have improved respiratory muscle strength as well as sleep quality and health-related quality of life in the exercise group. OPE along with CPAP therapy may be recommended in moderate and severe OSA patients who are willing to participate.

Background and Objectives: As with other chronic diseases with limited medical treatment, the most important goal of Alzheimer's disease (AD) treatment is to provide a better quality of life (QoL). The purpose of this study was to investigate the factors affecting the QoL of patients with mild to moderate AD in terms of patients and caregivers. Materials and Methods: Seventy-three home-dwelling patients with AD and their caregivers participated in this prospective, cross-sectional study. The patients were asked about their cognition, depression and a self-rating part of a QoL questionnaire. The caregivers were asked about their patients' sociodemographic information, sleepiness, activities of daily living and a proxy rating part of a QoL questionnaire. Results: The self-rated QoL was higher than that provided by the proxy rating. Cognition (p = 0.02), sleepiness (p < 0.01) and depression (p = 0.03) were correlated with the self-rated QoL, while the patient's independence level in activities of daily living was correlated with the proxy-rated QoL (p < 0.05). In regard to predicting QoL according to linear regression analysis, the following were statistically significant: depression was for total score, depression and cognition were for the self-rating and instrumental activities of daily living was for the proxy rating (p < 0.01). Conclusions: While individual factors such as psychology are an important determinant of QoL for patients with AD, objective conditions such as the independence of the patient in daily life are important for the caregiver. While evaluating the quality of life of AD patients, it is important to remember that patients and caregivers have different priorities, and the priorities of both should be taken into account when planning a treatment program.

OBJECTIVES: This study aims to assess postural balance, fall risk, and the relationship of these parameters with disease-related factors in patients with systemic sclerosis (SSc). PATIENTS AND METHODS: Thirty patients with SSc (6 males, 24 females; mean age 51.1±10.6 years; range 35 to 65) and 30 healthy subjects (6 males, 24 females, mean age 52.4±8.7 years; range 35 to 65) matched for age, sex and body mass index were included in this cross-sectional study conducted between September 2018 and November 2019. Postural balance was measured with Biodex Balance SystemTM (Biodex-BS), Berg Balance Scale (BBS), and Timed Up and Go (TUG) test. Individuals' history of falls in the past year, functional capacity, lower limb muscles strength, pulmonary function, respiratory muscle strength, diffusion capacity, and dyspnea severity were evaluated. RESULTS: The SSc group had postural balance impairment and a higher fall frequency than the control group. The SSc group had significantly higher sway index on postural stability (0.6±0.5), lower directional control score (42.1±8.0), and longer test duration (51.8±11.8) on limit of stability of Biodex-BS, lower BBS score (51.5±4.9), and longer test duration on TUG test (8.3±2.7) than control group (all p<0.05). Also, SSc group exhibited significantly lower functional capacity, limb muscles strength, pulmonary function, respiratory muscles strength, diffusion capacity, and higher dyspnea severity than control group (all p<0.05). The postural balance and fall frequency of SSc patients were significantly associated with functional capacity, lower limb muscles strength, pulmonary function, respiratory muscle strength, diffusion capacity, and dyspnea severity. CONCLUSION: Our results suggest that postural balance impairment and fall risk should be assessed as they appear to be important problems in patients with SSc. Furthermore, assessment of functional capacity, lower limb muscles strength, and lung involvement may highlight those with postural balance impairment and higher fall risk.
RESUMEN
BACKGROUND: Disease and aging-related factors may predispose chronic obstructive pulmonary disease (COPD) patients to impaired balance, although the underlying determinants of impaired balance in COPD patients are still unknown. The purpose of this study was to identify the determinants of impaired balance in COPD patients. Also, we aimed to determine which balance measures (clinical or laboratory tests) are more indicative in determining balance impairment in these patients. METHODS: This cross-sectional study recruited 24 patients with moderate to severe COPD and 24 age-matched healthy subjects. Participants were evaluated regarding demographic and clinical data, previous falls history, lower limb muscle strength, exercise capacity, physical activity and balance level. RESULTS: COPD patients exhibited significantly a longer test duration on timed up and go test, a higher sway index on the postural stability and lower directional control score on the limit of stability of Biodex balance system (all, pâ¯< 0.001) compared to healthy controls, whereas there was no difference in Berg balance scale score between groups (pâ¯> 0.05). Balance impairment of the patient group was significantly associated with nonpulmonary conditions, such as physical activity level, exercise capacity, lower limb muscle strength, and with fall history. Also, COPD patients represented significantly lower physical activity level and exercise capacity, weaker lower limb muscle strength than healthy controls (all, pâ¯< 0.001). CONCLUSIONS: Patients with moderate to severe COPD exhibit apparently important reductions in balance control that is directly associated with nonpulmonary consequences and fall history. These results may be extremely important to fall prevention and to guide the development of interventions for this population.

AIM: To compare the effects of supervised exercise and home exercise program in patients with systemic sclerosis (SSc). METHODS: Thirty-seven SSc patients were included. Patients with SSc were allocated into 2 groups as supervised and home exercise. Breathing, aerobic and resistance exercises were performed with a physiotherapist for 12 weeks in the supervised exercise group. Breathing, posture and aerobic exercises were given to the home exercise group as a home program for 12 weeks. All patients were assessed at baseline and 12 weeks later in terms of functional capacity, pulmonary functions, respiratory-peripheral muscle strength, dyspnea severity, health-related quality of life (HRQoL) and fatigue level. RESULTS: Significant improvements were observed in the functional capacity, measured by 6 minute walking test in the supervised exercise group (before = 376.21 ± 65.50, after = 518.78 ± 75.84 m) and home exercise group (before = 384.44 ± 68.14, after = 432.7 ± 70.8 m; (P < .05). Respiratory-peripheral muscle strength (with the exception of inspiratory muscle strength and upper limb strength in the home exercise group) and HRQoL were significantly increased and fatigue level was significantly decreased in the supervised exercise and home exercise groups (P < .05). However, pulmonary functions and dyspnea severity were significantly improved only in the supervised exercise group (P < .05). The supervised exercise program was found superior to the home exercise program for change in all parameters (P < .05). CONCLUSION: This study suggests that exercise interventions should be applied in addition to the medical treatments of patients with SSc as supervised and home exercise programs play an important role in the functionality and health status of these patients.

OBJECTIVE: To investigate the association of core stability with physical function and functional performance in patients with systemic sclerosis (SSc). METHODS: Forty patients who met the American College of Rheumatology / European League Against Rheumatism 2013 classification criteria for SSc were included in the cross-sectional study. For evaluation of core stability, trunk muscle endurance and trunk muscle strength were assessed. Trunk extensor and trunk flexor endurance tests were used for assessment of trunk muscle endurance. Trunk muscle strength was measured with a hand-held dynamometer and modified sit-up test. To measure physical function the Health Assessment Questionnaire Disability Index (HAQ-DI) and to measure functional performance 6-minute walking test (6MWT) and sit-to-stand test (STS) were used. RESULTS: Patients with SSc had lower mean trunk extensor and flexor endurance test times (49.87 ± 30.81 and 32.17 ± 15.42 seconds, respectively), modified sit-up test repetition (17.42 ± 7.81) and trunk extensor and flexor muscle strength (7.48 ± 2.29 kg and 6.20 ± 1.68 kg, respectively) when compared to the reference values in healthy individuals. All measurements were used to evaluate core stability associated with HAQ-DI score, 6DMWT walking distance and STS test duration (all P < .05). CONCLUSION: Patients with SSc have markedly reduced core stability and this negatively affects the physical function and functional performance. Therefore, this study highlights the importance of trunk muscle in patients with SSc. We suggest that not only upper-lower extremity muscles, but also trunk muscle strength and endurance should be measured and core stability exercises can be added to the training programs to maintain and/or improve physical functions and functional performance in SSc patients.

BACKGROUND: Although FEV1 and FEV1/FVC are accepted as standard parameters in treatment follow-up, these parameters have a limited ability to predict clinical outcomes in patients with COPD. However, small airways dysfunction, which is determined by maximum mid-expiratory flow, is variable in the same stage of patients with COPD, even if their FEV1 and FEV1/FVC are similar. The aim of this study was to compare pulmonary function, the severity of perceived dyspnea, the severity of fatigue, physical activity level, and health-related quality of life based on the severity of small airways dysfunction in male subjects with moderate COPD. METHODS: The study consisted of 96 subjects with moderate COPD. Pulmonary function tests, the distance achieved on the 6-min walk test, the modified Medical Research Council Dyspnea Scale, the International Physical Activity Questionnaire - short form, the Fatigue Severity Scale, the St George Respiratory Questionnaire, and Short Form 36 questionnaire were evaluated in all subjects. After calculating the mean percent of predicted maximum mid-expiratory flow for the entire sample, subjects were divided into 2 groups: below average (Group 1, n = 54 subjects) and above average (Group 2, n = 42 subjects). RESULTS: There were no differences between the groups in age, body mass index, cigarette consumption, percent of predicted FEV1, and FEV1/FVC (P = .55, .61, .19, .09, and .15, respectively). Scores from the Fatigue Severity Scale and the modified Medical Research Council dyspnea scale were significantly higher in Group 1 (P = .003 and P = .002, respectively); in addition, results from the 6-min walk test and the International Physical Activity Questionnaire - short form scores were significantly lower (P = .001 and P < .001, respectively). CONCLUSIONS: Increased small airways dysfunction led to increased perception of dyspnea and fatigue, as well as poor exercise capacity and health-related quality of life in male subjects with COPD. We suggest that it may be useful to consider the maximum mid-expiratory flow in addition to FEV1 and FEV1/FVC in the treatment and follow-up of male patients with moderate COPD.

Background/aim: Fatigue is very common symptom in patients with systemic sclerosis (SSc) and adversely affects health-related quality of life and the ability to perform daily living activities. This study aimed to determine the severity of fatigue, and its related factors, in patients with SSc. Materials and methods: A total of 35 patients with SSc (6 males and 29 females, mean age of 50.71 ± 10.09 years) and 35 healthy control subjects (8 males and 27 females, mean age of 54.14 ± 9.51 years) were included in this study. The Fatigue Impact Scale for fatigue, Modified Medical Research Council Scale for dyspnea severity, 6-Minute Walking Test for functional capacity, Health Assessment Questionnaire Disability Index, Scleroderma Health Assessment Questionnaire and Short Form-36 Quality of Life Questionnaire for health-related quality of life were used in the evaluation of the subjects. Furthermore, pulmonary functions, diffusion capacity, and respiratory and peripheral muscle strength were evaluated. Results: Of the SSc patients, 80% experienced fatigue and presented with higher total and cognitive, physical, and psychosocial subscale fatigue scores than the healthy control subjects (P < 0.05). Moreover, the SSc patients exhibited significantly increased dyspnea severity, impaired pulmonary function-diffusion capacity, decreased respiratory-peripheral muscle strength, reduced functional capacity, and worsened health-related quality of life when compared to the control group (P < 0.05). Fatigue in the SSc group was significantly associated with age, dyspnea severity, diffusion capacity, respiratory and peripheral muscle strength, functional capacity, and health- related quality of life (P < 0.05). Conclusions: Along with the decrease in diffusion capacity, increase dyspnea, a decrease in both peripheral and respiratory muscle strength, and worsening functional capacity may have an effect on increased fatigue in SSc patients. Increased fatigue can also affect the life quality and daily life activities of a patient. Therefore, multidisciplinary approaches are recommended to evaluate and improve these parameters in the treatment of fatigue from the early period in SSc patients.
