Investigation of the Effects of Functional Inspiratory Muscle Training in Patients With Lung Cancer

Официальное название

Investigation of the Effects of Functional Inspiratory Muscle Training on Oxygen Consumption, Muscle Oxygenation, Balance and Physical Activity Level in Patients With Lung Cancer

Обзор

Patients' pulmonary functions and diffusion capacity worsen following lung cancer surgery. Diaphragmatic activity and lung compliance decrease due to surgery. Peripheral and respiratory muscle functions are impaired in patients with lung cancer, exercise capacity and physical activity level decreased. Patients have postural instability and balance problems. Inspiratory muscle training has increased inspiratory muscle strength in patients with lung cancer. However, there is no study investigating functional inspiratory muscle training in patients with lung cancer.

Подробное описание

Lung cancer is a malignant lung tumor characterized by uncontrolled cell growth in lung tissues. The main treatment methods for lung cancer are chemotherapy, radiotherapy, and surgery. Molecularly targeted therapy and immunotherapy are also among the treatment options. Patients with lung cancer experience various symptoms such as dyspnea, cough, chest pain, hemoptysis, fatigue, weight loss due to the disease process, the effects of chemotherapy and radiotherapy treatment, and comorbidities. The treatment method varies depending on the histological type, stage, location of the tumor, and the physical condition of the patient. Surgery is performed as a therapeutic option for many patients with lung cancer. Lung cancer surgery impair the cardiorespiratory functions of the patients. Patients' pulmonary functions and diffusion capacity worsen following lung cancer surgery. In lung cancer patients, the incision applied to the respiratory muscles due to surgery and changes in the mechanics of the chest wall cause worsening of respiratory muscle function. The condition results in dyspnea in patients at rest and during activities of daily living. Mitochondrial dysfunction due to the pathogenesis of the disease and chemotherapy/radiotherapy leads to deterioration in muscle oxygen metabolism. In individuals with reduced muscle oxygen, exercise tolerance and muscle strength decrease. Impairment of diaphragm function is associated with decreased postural stability after lung cancer surgery. Patients with lung cancer have postural instability and balance problems. Lung cancer significantly affects the quality of life of patients, limiting their physical and social activities. Inspiratory muscle training is recommended as part of disease management for lung cancer. In the literature, there are studies investigating the effectiveness of inspiratory muscle training in lung cancer patients in the preoperative, perioperative, and postoperative periods. However, there is no study investigating functional inspiratory muscle training in patients with lung cancer. Functional inspiratory muscle training (IMT) was developed by McConnell. It is a program that is based on the functions of respiratory muscles other than breathing, and IMT is applied along with exercise.

The primary aim of this study: To investigate the effects of functional inspiratory muscle training on oxygen consumption, muscle oxygenation, balance and physical activity level in patients with lung cancer.

The secondary aim of this study: To investigate the effects of functional inspiratory muscle training on pulmonary functions, peripheral and respiratory muscle strength, inspiratory and trunk muscle endurance, cough strength, fatigue, dyspnea and quality of life in patients with lung cancer.

Вмешательства

• Устройство Functional inspiratory muscle training group
  Patients will be given fundamental inspiratory muscle training with the inspiratory muscle training device at 50% of the maximal inspiratory pressure 30 min/day, 3 days/week for 4 weeks online with a physiotherapist. On the other days of the week, the training will be used as a home program. In the 5th week, the functional inspiratory muscle training program will be started. Before the program begins, patients will be shown the exercises in the functional inspiratory muscle training program. Pa
• Устройство Control group
  The control group will not be given any training during the 8-week period. 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.
