문제 정의
- This study examined how inspiratory muscle training (IMT) affected the diaphragm thickness, pulmonary function, and chest expansion of chronic stroke patients. The results showed that stroke patients had experienced a decline in exercise capacity and deteriorated coordination of the respiratory muscle due to a damaged motor cortex.
제안 방법
- , 1993). Recognizing that IMT could benefit patients with a cardiac disease or COPD (Chronic Obstructive Pulmonary Disease), this study established a hypothesis that IMT could improve pulmonary function in chronic stroke patients and the researchers conducted an experiment accordingly.
- We admit some limitations of the study. The researchers conducted a six-week experiment, and due to the short period of experiment, it was difficult to examine the long-term effects of IMT. Also, the subjects were not randomly selected.
- To assess functional residual capacity (FRC), diaphragm thickness was measured first. The subject changed to an upright sitting position and wore a spirometer nose clip and mouth piece in order that the diaphragm thickness at functional residual capacity (Tdi.rel) could be measured (ICC .86, 95%CI .81 to .91). The subjects were asked to keep the maximum inspiratory mouth pressure (PImax) possible for two seconds so that diaphragm thickness at total lung capacity (Tdi.
- The experiment subjects were people who had been diagnosed with a stroke through computed tomography, had partial impairment in the cerebral hemisphere, and had a secondary injury of hemiplegia. The subjects had been with effects of a stroke for longer than six months and were undergoing general physical therapy, including neurological treatment, though without special treatment to enhance pulmonary function. Those who had an innate thorax deformity, were incapable of performing the respiratory-system mechanics due to a rib fracture, or had a disease related to lungs, kidneys, the endocrine system, orthopedics, or rheumatology were excluded from the experiment.
- To measure the degrees of consciousness concerning the subjects’ fatigue, the Borg Rating of Perceived Exertion (RPE) was used (Borg, 1982). The subjects recorded a log documenting their exercise adherence, the Borg RPE, and daily symptoms. Patients who developed lightheadedness were removed from the training and resumed the training after the symptom was gone.
- Only a few studies have been undertaken concerning IMT’s impact on the pulmonary function of chronic stroke patients with restrictive respiratory patterns. Therefore, this study applies IMT to chronic stroke patients over a period of six weeks and observes changes in their diaphragm thickness, pulmonary function, and chest expansion.
대상 데이터
- Blinding the patients was not possible because of the nature of the treatment. In the end, 33 stroke patients participated in the experiment. They had a full understanding of its objective and consented to participation.

- The intervention group had seven males and eight females; among them, nine had right hemiplegia and six had left hemiplegia. The control group had nine males and six females; among them, six had right hemiplegia and nine had left hemiplegia.

- 05. The study conducted a paired t-test to examine the effect of the training intervention and conducted an independent t-test to observe differences between the two groups.
이론/모형
- To measure the degrees of consciousness concerning the subjects’ fatigue, the Borg Rating of Perceived Exertion (RPE) was used (Borg, 1982).
성능/효과
- Regarding FVC, its average value increased but not at a statistically significant level. Also, regarding the FEV1/FVC ratio, the average value increased in the IMT group and decreased in the control group, and yet the difference was not found to be statistically significant. Previous studies identified the most effective length of an IMT program to be six to eight weeks (Teixeira-Salmela et al.
- examined 46 multiple sclerosis patients and applied a ten-week IMT session to twenty patients in an experimental group that used an inspiratory-muscle threshold trainer. Following the training, FEV1andFVC significantly increased in the experimental group, as did FEV (by 25 to 75 percent). However, the FEV1/FVC ratio did not increase significantly (Fry et al.
- The control group had nine males and six females; among them, six had right hemiplegia and nine had left hemiplegia. General characteristics of the two groups were examined in advance, and no significant difference was found in terms of age, height, body weight, diaphragm thickness, lung function, and chest expansion (Table 1).
- , 2005). Presumably, FVC and the FEV1/FVC ratio in this study would have shown significant increases if the IMT had lasted longer than six weeks.
- , 2010). The results showed that FEV1andFVC increased significantly in the IMT group, but PEF did not. As well, Fry et al.
- This study examined how inspiratory muscle training (IMT) affected the diaphragm thickness, pulmonary function, and chest expansion of chronic stroke patients. The results showed that stroke patients had experienced a decline in exercise capacity and deteriorated coordination of the respiratory muscle due to a damaged motor cortex. As a stroke develops into a chronic stage, patients’ pulmonary function keeps declining due to an inactive lifestyle.
- As a stroke develops into a chronic stage, patients’ pulmonary function keeps declining due to an inactive lifestyle. The study applied IMT to stroke patients for six weeks, and the results showed that their diaphragm thickness, thickness ratio (TR), and pulmonary function increased. These findings suggest that IMT could be an adequate intervention method for enhancing the diaphragm mobility and pulmonary function of chronic stroke patients.
- , 2006), even though the previous study’s subjects were not stroke patients. The study results suggest that IMT applies a load to the inspiratory muscles, increases diaphragm thickness, and enhances pulmonary mechanics. This study showed that continued application of IMT also affects diaphragm thickness in stroke patients, and its impact on stroke patients is consistent with the overload principle (Kraemer et al.
