Clinical Trial Summary

Severe dyspnea, cough, fatigue, restrictive type ventilation disorder, decreased pulmonary function, impaired gas exchange, decreased cardiovascular function and exercise intolerance are frequently encountered findings in patients with interstitial lung disease. It was demonstrated exercise training has beneficial effects in patients with interstitial lung disease. However, no study investigated the effects of upper extremity aerobic exercise training on outcomes in patients with interstitial lung disease.

Description:

Interstitial lung diseases (ILD) are a heterogeneous group of diseases that cause significant mortality and morbidity worldwide. As a result of the chronic inflammatory process in this disease, structural and mechanical pulmonary disorders develop, which are considered the main causes of deterioration in cardiopulmonary functions. Interstitial lung patients have a decrease in both static and dynamic lung volumes and carbon monoxide diffusing capacity (DLCO). As a result of this pathological mechanism, effort dyspnea and an increase in exercise intolerance occur. Therefore, individuals with ILD tend to avoid activities that increase shortness of breath, resulting in decreased physical activity levels and an increased sedentary lifestyle. Individuals whose functional exercise capacities are also limited due to this vicious circle become more dependent in their daily living activities. In addition, peripheral muscle dysfunction is another important factor that causes exercise intolerance in individuals with all chronic lung diseases, including ILD. One of the most important mechanisms triggering peripheral muscle dysfunction in ILD is hypoxia which develops with desaturation. Hypoxia, which causes an increase in oxidative stress, is one of the factors that can cause muscle dysfunction. It has been reported that upper extremity exercise capacity and functional performance are low in individuals with advanced ILD, and it has been stated that upper extremity exercise training may be beneficial in these patients.

However, the effects of upper extremity aerobic exercise training have not been investigated in the literature in patients with ILD. In this context, the primary aim of our study is to investigate the effects of upper extremity interval aerobic exercise training applied to patients with ILD on oxygen consumption, muscle oxygenation, and physical activity level. The secondary aim of the study is to determine the effects of this training on upper extremity functional exercise capacity, respiratory functions, pulmonary diffusion capacity, respiratory and peripheral muscle strength, inspiratory muscle endurance, dyspnea, fatigue, quality of life, sleep quality, anxiety, and depression. For this purpose, our study was planned as a randomized, controlled, three-blind (investigators, patient, and analyzer) prospective study. According to the block randomization result, at least 21 patients with a diagnosis of ILD will be included in the training and control groups.

The training group will be given upper extremity interval aerobic exercise training with arm ergometer for 30-45 minutes 3 days a week for 6 weeks, and the control group will not be given any training during the study. After the study, the treatment applied to the training group will also be applied to the control group in order to ensure that the patients in the control group are not ethically deprived of rehabilitation.

All assessments will be completed in two days, before and after six weeks of training.

The presence of any symptoms during the test, supplemental oxygen support, and assistive device usage status will be recorded.	through study completion, an average of 2 year
Secondary	Dyspnea perception	"Modified Medical Research Council" dyspnea scale will be used to question dyspnea perception during activities. This scale is a 5-point scale based on rating various physical activities that increase shortness of breath. The lowest and highest values on this scale are as follows: Level 0 "No shortness of breath except strenuous exercise" and level 4 "Too breathless to leave the house or breathless while dressing or undressing."; The London Chest Activity of Daily Living scale (Turkish version) will be used to evaluate dyspnea perception during activities of daily living in patients. The scale has a total of 4 subheadings and a total of 15 items, including personal care (4 items), household chores (6 items), physical (2 items) and leisure (3 items). Each item is scored on a scale of 0-5 points. Sub-title score and total score are evaluated. The total score is a maximum of 75. As the overall score increases, so does the dependence on activities of daily living.	through study completion, an average of 2 year
Secondary	Fatigue	Fatigue will be assessed with Fatigue Severity Scale (Turkish version). This scale includes 9 items and each item scores from 1 (strong disagreement) to 7 (strong agreement) point. Fatigue Severity Scale total score is calculates by deriving an arithmetic mean. Cut-score of over 4 means significant fatigue and higher score indicates more severe fatigue.	through study completion, an average of 2 year
Secondary	Life Quality	Quality of life will be assessed with Saint George Respiratory Questionnaire (SGRQ) (Turkish version). This questionnaire is a questionnaire used to evaluate the quality of life in respiratory diseases. The questionnaire consists of 3 parts: symptoms (8 items), activities (16 items), effects of the disease (26 items) and a total of 50 items: 3 parts of the test are scored separately. Then the total score is obtained. The total score ranges from 0-100. A score of zero is normal, while a score of 100 represents maximum disability. As the total score increases, it indicates that poor quality of life. In this questionnaire, a change of 4 points with treatment is considered significant.	through study completion, an average of 2 year
Secondary	Sleep Quality	The Pittsburgh Sleep Quality Index (Turkish version) will be used to evaluate the sleep quality of the patients. 19 of the questions in the index, which consists of a total of 24 questions, are questions that the individual answers by evaluating himself/herself. The remaining 5 questions are answered by the individual's bed partner or roommate, if any. The questionnaire includes questions asked under 7 main headings: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleeping medication, and daytime functions. Each of these 7 main headings is first evaluated in its own right. The scores of the 7 components are then summed up. If the total score is above 5 points, it is considered bad sleep.	through study completion, an average of 2 year
Secondary	Anxiety and Depression	Hospital Anxiety and Depression Scale (Turkish version) will be used to evaluate the anxiety and depression levels of the patients. It consists of two subdivisions: Anxiety (HAD-A) and depression (HAD-D). 7 questions consisting of odd numbers (questions 1, 3, 5, 7, 9, 11, 13) measure anxiety, and 7 questions consisting of even numbers (questions 2, 4, 6, 8, 10, 12, 14) measure depression. For the answers to each question, a score of 0-3 is made in the form of a quadruple likert. The lowest score that can be obtained from both subscales is 0 and the highest score is 21. As the score increases, the severity of anxiety and depression increases. 0-7 is considered normal, 8-10 is borderline, 11 and above is considered abnormal. 10 points and above for anxiety and 8 points and above for depression are considered significant.	through study completion, an average of 2 year
Secondary	Modified Borg scale	The assessment of dyspnea and fatigue perception in all patients at rest, during, and after exercise training will be performed with the Modified Borg scale. In addition, the perception of dyspnea and fatigue before, during, and after the cardiopulmonary exercise test and 6 minutes of pegboard and ring test will be evaluated with the Modified Borg scale. The modified Borg scale is a subjective scale and scores patients' dyspnea at rest and/or during activity on a scale of 0-10. The lowest score of 0 (zero) indicates "not at all" and the highest score of 10 (ten) indicates "very very serious" shortness of breath or fatigue.	through study completion, an average of 2 year

It refers the average flow from the point at which 25% of the FVC has been exhaled to the point at which 75% of the FVC has been exhaled. It is expressed in liters (L) and as a percentage (%) of the expected value.	through study completion, an average of 2 year
Secondary	Diffusion capacity for carbon monoxide (DLCO)	Carbon monoxide diffusing capacity of the lung (DLCO) is a measurement to assess the lungs' ability to transfer gas from inspired air to the bloodstream. Its measurement uses carbon monoxide to calculate the pulmonary diffusion capacity. The most common method is the standard single-breathe diffusing capacity test. It is expressed in mmol/(min*kPa) and as a percentage (%) of the expected value.	through study completion, an average of 2 year
Secondary	Carbon monoxide transfer coefficient (KCO=DLCO/Va)	KCO is CO transfer coefficient, usually written as DLCO/Va, which indicates the efficiency of CO transfer by alveoli. In other words, it is the diffusion capacity of carbon monoxide for each unit of the alveolar volume. The most common method is the standard single-breathe diffusing capacity test. It is expressed in mmol/(min*kPa*L) and as a percentage (%) of the expected value.	through study completion, an average of 2 year
