Detailed Description
Hyperthyroidism is a pathological disease in which the synthesis and secretion of thyroid hormones are increased by the thyroid gland. Thyroid hormone excess affects many systems. Common clinical symptoms are fatigue, palpitations, disturbed sleep, weight loss, heat intolerance, sweating, tremors, polydipsia, and anxiety. Common physical findings are tachycardia, extremity tremors and weight loss.
Thyroid hormone directly affects skeletal muscles. Increased thyroid hormone causes myopathy with a decrease in muscle strength and mass. Hyperthyroid myopathy can cause a decrease in exercise capacity. The main cause of exercise intolerance in individuals with hyperthyroidism is the change in energy metabolism. The number of studies investigating the exercise capacity in hyperthyroid patients is limited. Information support will be provided to the literature by evaluating the exercise capacity in patients with hyperthyroidism.
Physical activity is positively associated with changes in cardiovascular risk factors. Neuromuscular symptoms and exercise intolerance seen with thyroid hormone excess can lead people to an inactive life. Indirect calorimetry, the gold standard in energy expenditure, has been shown to be highly correlated with metabolic holter.There are no studies evaluating physical activity level with metabolic holter in individuals with hyperthyroidism. In this study, physical activity level will be evaluated by metabolic holter.
Patients with hyperthyroidism referred to the Cardiopulmonary Rehabilitation Unit of Gazi University Physiotherapy and Rehabilitation Department by the physicians of the Department of Endocrinology and Metabolism of the Department of Internal Diseases of Gazi University Faculty of Medicine will be included in the study. Patients and healthy individuals will be evaluated and the evaluation results will be compared. According to the sample size analysis 15 patients and 15 healthy individuals with similar demographic characteristics will be included the study. Patients and healthy individuals will be selected according to predetermined inclusion and exclusion criteria. Patients will be evaluated twice. The first evaluation will be made in the new diagnosis. The second evaluation will be made in the euthyroidism.The assessments will be completed in two days.
Functional exercise capacity (6 minutes walk test and 6 minutes stepper test), physical activity level (multi-sensor activity monitor), respiratory functions (spirometer), respiratory muscle strength (mouth pressure measurement), peripheral muscle strength (dynamometer), respiratory muscle endurance (incremental threshold loading test), quality of life (The Thyroid-Related Quality of Life-ThyPRO), fatigue (Fatigue Severity Scale), depression-anxiety-stress (Depression Anxiety Stress Scale-42), quality of sleep (Pittsburgh Sleep Quality Index) and shortness of breath (Modified Medical Research Council (MMRC)) will be evaluated.

- Disease Specific Quality of Life [First Day]
Quality of life was evaluated with the Turkish version of the Quality of Life Scale (ThyPRO) in Thyroid Patients. For each question, a five-point Likert type (0 = not at all, 1 = very little, 2 = a little, 3 = a little bit, 4 = a lot) was used. Each subscale is scored differently. High scores indicate a decreased quality of life.
- Fatigue [First Day]
Fatigue will be evaluated using Turkish version of Fatigue Severity Scale. This questionnaire includes 9 items and score range for each item from 1 to 7 point (7-point Likert scale). Fatigue Severity Scale score is calculates by deriving an arithmetic mean. Cut-scores of over 4 are indicative of significant fatigue (higher scores show more severe fatigue)score range for each item from 1 to 7 point (7-point Likert scale).
- Shortness of breath [First Day]
The Modified Medical Research Council (MMRC) dyspnea scale will be used to determine the perception of dyspnea during activities of daily living. Dyspnea is graded as: zero (shortness of breath with strenuous exercise only); one (shortness of breath when rushing or walking up a slight uphill); two (because of shortness of breath they walk slower than people of the same age or have to stop to breathe while walking at their own pace); three (stops to breathe after walking 100 meters or after a few minutes); and four (too short of breath to leave the house or shortness of breath when getting dressed).daily living activities.
- Sleep Quality [First Day]
Sleep quality will be evaluated by Turkish adaptation of Pittsburgh Sleep Quality Index (PSQI). The scale includes 24 questions. The questions included in the scoring consist of seven components: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleeping pills, and daytime dysfunction. Total PSQI score varies between 0-21. A total score greater than five indicates "poor sleep quality".
