Detaillierte Beschreibung
Chronic obstructive pulmonary disease (COPD) is a disease that leads to increased morbidity and mortality with severe pulmonary complications. The Global Burden of Disease studies have estimated that COPD is the third leading cause of death worldwide. The effects of COPD are not only limited to the lungs but also affects other organs and systems, causing loss of strength in the respiratory and peripheral muscles, which leading to a decreased capacity for exercise. Respiratory muscles are the skeletal muscles that can be trained based on the principles of exercise just like peripheral muscles. It is known that while doing exercise training in peripheral muscles, more muscle performance can be achieved by warming up those muscles before the loading phase. In this study, it is aimed to investigate the effect of inspiratory muscle warm-up (IMW) performed before inspiratory muscle training (IMT) in addition to general exercise training on respiratory functions, respiratory muscle strength, exercise capacity, perceived dyspnea intensity and health-related quality of life in patients with COPD.
Participants were randomly divided into two groups as the study group (IMW Group) and the control group (Standard IMT Group). The Standard IMT Group performed only IMT, while the IMW Group performed an IMW protocol for warming the inspiratory muscles before each IMT session. The IMT and IMW were applied using a threshold pressure loading device. The IMT applied as 30 breath repetitions at 60% of the maximal inspiratory pressure (MIP). The intensity of MIP adjusts by two weekly MIP measurements. The protocol of IMW consists of 2 sets of 30 breaths at 40% of MIP, with 1 min rest between sets, using a threshold inspiratory muscle trainer. Then the respiratory exercises and aerobic exercise program performed in both groups in each session. Aerobic exercise program; After 5 min of general body warming, applied 20 min with a load of 4-6 according to the modified Borg scale on the treadmill, finished with 5 min whole body cool-down. All program applied to 3 days a week for 8 weeks under the supervision of a physiotherapist and other days of the week without a supervisor. Demographic features questioned and recorded in the data recording form through a mutual interview in patients who meet the inclusion criteria. All patients evaluated before treatment and after treatment.

Experimental: IMW Group
Patients who performed inspiratory muscle warm-up (IMW) before inspiratory muscle training (IMT)
|
The IMW protocol applied before each inspiratory muscle training (IMT) session by using a threshold inspiratory muscle trainer.
The IMW protocol consists of 2 sets of 30 breaths in 40% of the maximal inspiratory pressure (MIP), with 1 min rest between sets.
The intensity of MIP adjusted by two weekly MIP measurements.
The IMT applied twice a day as 30 breath repetitions at 60% of the maximal inspiratory pressure (MIP).
The intensity of MIP adjusted by two weekly MIP measurements.
Then the respiratory exercises and aerobic exercise program performed in both groups in each session.
Aerobic exercise program; After 5 min of general body warming, applied 20 min with a load of 4-6 according to the modified Borg scale on the treadmill, finished with 5 min whole body cool-down.
All program applied to 3 days a week for 8 weeks under the supervision of a physiotherapist and other days of the week without a supervisor.

Experimental: Standart IMT Group
Patients who performed standard inspiratory muscle training (IMT) without inspiratory muscle warm-up (IMW) protocol
|
The IMT applied twice a day as 30 breath repetitions at 60% of the maximal inspiratory pressure (MIP).
The intensity of MIP adjusted by two weekly MIP measurements.
Then the respiratory exercises and aerobic exercise program performed in both groups in each session.
Aerobic exercise program; After 5 min of general body warming, applied 20 min with a load of 4-6 according to the modified Borg scale on the treadmill, finished with 5 min whole body cool-down.
All program applied to 3 days a week for 8 weeks under the supervision of a physiotherapist and other days of the week without a supervisor.

Inspiratorische Muskelkraft
Zeitfenster: 8 Wochen
|
Die inspiratorische Muskelkraft (MIP) wurde mit einem tragbaren Munddruckgerät (Micro RMP; Micro Medical, Rochester, UK) gemessen.
Drei bis fünf akzeptable und reproduzierbare Maximalmanöver (d. h. Unterschiede zwischen den Werten < 10 %) wurden durchgeführt und der höchste Wert wurde aufgezeichnet.

Die exspiratorische Muskelkraft (MEP) wurde mit einem tragbaren Munddruckgerät (Micro RMP; Micro Medical, Rochester, UK) gemessen.
Drei bis fünf akzeptable und reproduzierbare Maximalmanöver (d. h. Unterschiede zwischen den Werten < 10 %) wurden durchgeführt und der höchste Wert wurde aufgezeichnet.

Respiratory functions
Zeitfenster: 8 weeks
|
Respiratory functions were evaluated by pulmonary function tests.
Pulmonary function tests were performed in accordance with the American Thoracic Society (ATS) / European Respiratory Society (ERS) criteria, in a sitting position with a computer-compatible spirometer (Sensor Medics Vmax 22 machine, SensorMedics Inc., Anaheim, CA).
Percentages of forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and FEV1 / FVC ratio values relative to the predicted value were recorded in pulmonary function tests.

|
The modified Medical Research Council (mMRC) Dyspnea Scale was used to evaluate the severity of dyspnea.
Commonly used in the assessment of dyspnea in COPD, mMRC has a five-level scoring system ranging from 0 to 4. A high score indicates an increased sense of dyspnea.

Bewertung der gesundheitsbezogenen Lebensqualität mit dem St. George's Respiratory Questionnaire (SGRQ)
Zeitfenster: 8 Wochen
|
Der SGRQ ist ein spezifischer Fragebogen für Atemwegserkrankungen.
Es handelt sich um einen von Patienten selbst auszufüllenden Fragebogen, bei dem 50 Items mit 76 gewichteten Antworten abgefragt wurden, die in drei Bereiche unterteilt waren: Symptome (8 Items), Aktivitäten (16 Items), Auswirkungen der Krankheit (26 Items).
Die drei Teile des Fragebogens werden getrennt bewertet und die Gesamtpunktzahl errechnet.
Die Werte reichen von 0-100.
Höhere Werte weisen auf eine schlechtere HRQOL hin.
