About

This study aims to determine the effects of balloon inflation and pursed-lip breathing exercises, in addition to the forward-leaning position, on physiological parameters in individuals with Chronic Obstructive Pulmonary Disease (COPD).

The hypotheses of the study are as follows:

H1_1: The forward-leaning position and balloon inflation breathing exercise have a positive effect on physiological parameters in patients with Chronic Obstructive Pulmonary Disease (COPD).

H1_2: The forward-leaning position and pursed-lip breathing exercise have a positive effect on physiological parameters in patients with COPD.

H1_3: There is a significant difference in physiological parameters between the balloon inflation and pursed-lip breathing exercise groups and the control group.

Within this scope, the study will be conducted with three groups:

Intervention Group 1: Balloon inflation exercise applied in addition to the forward-leaning position.

Intervention Group 2: Pursed-lip breathing exercise applied in addition to the forward-leaning position.

Control Group: Standard practice implemented in the institution where the study is conducted.

Participants:

A home exercise program will be designed for both intervention groups, allowing them to perform the exercises independently each day.
The exercises will start with three sessions per day and will be increased by one session each week, continuing for a total of four weeks.
Participants will visit the outpatient clinic in the 4th week for assessments and tests.
Patients will be contacted weekly by the researcher via phone to ensure adherence to the program.

Full description

The exercise program will be determined in collaboration with a respiratory physiotherapist and implemented by the researcher. Accordingly, patients with stage II-III COPD (as determined by a physician) who visit the pulmonology outpatient clinic of the relevant hospital and meet the inclusion criteria will be given brief information about respiratory exercises, their benefits, and duration. They will then be instructed on how to perform the exercises through verbal commands for approximately 30 minutes. At the end of the session, the exercise guidelines will be practiced under the supervision of the researcher.

Before starting, the patient will be seated in a chair and allowed to rest for about 15 minutes. The patient will be informed about how to perform the walking test, the expected walking pace, and that they can stop and rest if they feel fatigued. Then, the patient will be asked to walk at a brisk pace for six minutes under the supervision of the researcher. During the walk, the researcher will continuously monitor the patient's oxygen saturation using a handheld pulse oximeter. If the patient exhibits signs of excessive sweating, pallor, or a significant drop in oxygen levels, the test will be terminated early.

Before and after the test, blood pressure, pulse rate, respiratory rate, oxygen saturation [SpO2], and dyspnea score using the Modified Borg Scale will be assessed, and the distance the patient walks in six minutes will be recorded. The six-minute walk test will be repeated at the end of the study. Subsequently, the patient will undergo a pulmonary function test, and the values for FVC, FEV1, FEV1/FVC ratio, and peak expiratory flow will be recorded.
