简要总结
This study investigates the effect of threshold inspiratory muscle training on diaphragm thickness and diaphragm excursion, measured using ultrasonography, in patients with stable chronic obstructive pulmonary disease (COPD).
详细描述
This quasi-experimental study with a pretest-posttest design evaluates the effect of a 6-week structured threshold inspiratory muscle training program on diaphragm thickness and diaphragm excursion in patients with stable COPD. Conducted at the medical rehabilitation polyclinic of Rotinsulu Hospital, Bandung, this study includes patients who meet specific inclusion criteria. The intervention is performed once daily, five times per week, with progressive intensity based on maximal inspiratory pressure using a threshold device. Outcomes will be assessed using ultrasonography to measure diaphragm thickness and diaphragm excursion before and after the intervention.

结局指标
主要结局
Diaphragm Thickness (cm)
时间窗: Baseline to Week 6
Diaphragm thickness reflects the structural characteristics of the diaphragm muscle and is measured at end-inspiration and end-expiration using ultrasonography. The values are expressed in centimeters (cm).
Diaphragm Excursion (cm)
时间窗: Baseline to Week 6
Diaphragm excursion represents the vertical movement of the diaphragm during the respiratory cycle, reflecting diaphragmatic mobility and function. Measurements are obtained using ultrasonography and expressed in centimeters (cm).
次要结局
- Forced Vital Capacity (FVC)(Baseline to Week 6)
- Forced Expiratory Volume in one second (FEV1)(Baseline to Week 6)
- Peak Expiratory Flow (PEF)(Baseline to Week 6)
