The purpose of this study was to find out an inspiratory muscles training program's therapeutic effects on stroke patients' respiratory function. For the purpose, this study targeted 20 stroke patients being hospitalized in K hospital in Daegu, and diveded the patients into the both groups of Inspiratory muscle training(IMT) group and control group, randomization. The 10 patients in the IMT group was applied the inspiratory muscles training. The control group was composed of other 10 patients. IMT group was given a inspiratory muscle training program for 30 minutes per times, 5 times a week for 6 weeks. The investigator measured the patients' respiratory function compared changes in the function and ability before and after the IMT. The results of this study are as follows. Investigating the inspiratory muscle training group's lung functions, there appeared some significant differences in the tests the FVC(Forced vital capacity), FEV1(Forced expired volume in one second) before and after the training(p<.05), but the control group had no significant in the same tests before and after(p<.05). The differences in the both groups after depending the inspiratory muscles training were significantly found in the tests of FVC, FEV1, FEV1/FVC(p<.05). The maximum inspiratory pressure showed some significant differences in the inspiratory muscle training group(p<.05), but didn't show any significant difference in the control group(p>.05). Conclusionally, it will be judged that the inspiratory muscles training program will improve stroke patients' respiratory function, and it is considered that will move up stroke patients' gait and body function.

PURPOSE: This study compared two different techniques of treadmill gait training, and evaluated the outcomes on gait and respiratory function in patients with hemiplegic stroke. METHODS: This was a single-blinded, randomized, controlled, comparative study, enrolling a total of 21 stroke patients in a rehabilitation hospital. Subjects were randomly assigned to either the treadmill walking training group with gradual speed increase (GSI group, n = 10), or treadmill walking training group with random speed changing (RSC group, n = 11). All participants performed 60 min of comprehensive rehabilitation therapy (5 × / week for 6 weeks). In additional, each group received either GSI or RSC treadmill walking training for 20 min (5 × / week for 6 weeks, total 30 sessions). Gait and respiratory function were measured before and after the 6-week training. RESULTS: Both groups showed significant improvements in the 10-m walking test, 6-minute walking test, timed up and go test, forced vital capacity (FVC), forced expiratory volume in 1 second, and maximal voluntary ventilation after training (p < .05). The GSI group showed a significantly greater increase in the FVC than the RSC group (+14.8 L vs. +12.5 L, p < .05). CONCLUSION: Both training methods can be effective for improving the walking and respiratory functions of stroke patients. However, our results indicate that treadmill walking training with gradual speed increase might be a more effective method for improving the respiratory function (FVC) than treadmill walking training with random speed changing.

Theoretically one might suggest the abdominoplasty can cause respiratory decompensation resulting from musculofascial plication, which reduces the respiratory reserve by decreasing intra-abdominal volume and diaphragmatic excursion. This prospective study was perfomed to evaluate the effect of abdominoplasty and the change of intraoperative Paw on the pulmonary function of 20 consecutive otherwise healthy subjects. The pulmonary function test was performed preoperatively, and repeated 2 months after the operation. Additionally, we monitored intraoperative Paw. Comparison of the pulmonary function test showed a significant decrease(p<0.001) in the mean forced vital capacity(FVC) and the mean forced expiratory volume in one second($FEV_1$) throughout the study period. Postoperatively, the mean FVC decreased by 11.65% and the mean $FEV_1$ decreased by 16.15%. The mean Paw increased by $6.6cmH_2O$($3-12cmH_2O$) by musculofascial plication. And we found that the decrease in FVC and $FEV_1$ was significantly correlated with intraoperative changing of Paw in abdominoplasty(p<0.001). FVC and $FEV_1$ could be decreased by abdominoplasty due to decreasing intra-abdominal volume and diaphragmatic excursion, but there was no respiratory symptom clinically in all patients 2 months after the operation. In conclusion, We found that the decrease in FVC and FEV1 after 2 months of abdominoplasty was significantly correlated with intraoperative Paw change during operation. The intraoperative Paw was increased to $12cmH_2O$ without any respiratory symptom in this study. We suggested that the increase in intraoperative Paw less than about $10cmH_2O$ can not affect on respiratory function clinically.

Background: Chronic obstructive pulmonary disease (COPD) is a serious chronic condition with a global impact. Symptoms of COPD include progressive dyspnea, breathlessness, cough, and sputum production, which have a considerable impact on the lives of patients. In addition to the human cost of living with COPD and the resulting death, COPD entails a huge economic burden on the Chinese population, with patients spending up to one-third of the average family income on COPD management in some regions is clinically beneficial to adopt preventable measures via prudent COPD care utilization, monetary costs, and hospitalizations. Methods: Toward this end, this study compared the relative effectiveness of six indices in predicting patient healthcare utilization, cost of care, and patient health outcome. The six assessment systems evaluated included the three multidimensional Body mass index, Obstruction, Dyspnea, Exercise capacity index, Dyspnea, Obstruction, Smoking, Exacerbation (DOSE) index, and COPD Assessment Test index, or the unidimensional measures that best predict the future of patient healthcare utilization, cost of care, and patient health outcome among Chinese COPD patients. Results: Multiple linear regression models were created for each healthcare utilization, cost, and outcome including a single COPD index and the same group of demographic variables for each of the outcomes. Conclusion: We conclude that the DOSE index facilitates the prediction of patient healthcare utilization, disease expenditure, and negative clinical outcomes. Our study indicates that the DOSE index has a potential role beyond clinical predictions.

The aim of this study was to investigate the effects of respiratory muscle training (RMT) with abdominal drawing-in maneuver (ADIM) on pulmonary function. Twenty-two subjects with restrictive breathing participated in this study. All the subjects were randomly assigned to three groups (7 subjects in RMT group, 7 subjects in RMT with ADIM group, 8 subjects in control group). The first group performed the RMT by using incentive respiratory spirometer (IRS). The second group performed the RMT by using IRS and the ADIM by using a Stabilizer. The exercises were conducted over four days. The pulmonary function was evaluated using the spirometer to measure the force exploratory volume in 1 second ($FEV_1$) and forced vital capacity (FVC). Measurements were conducted on the first day and the last day. A paired-t test was used for pre-post changes and the change rates in FVC and $FEV_1$ among each group were investigated by a one-way ANOVA. The findings of the the study were as follows: 1) There were significant differences of FVC and $FEV_1$ between pre and post in the two training groups (p<.05) 2) There was no significant difference of the change ratio the FVC and $FEV_1$ between the RMT group and RMT with ADIM group. Therefore, it is concluded that respiratory muscle and ADIM training, combined with two methods of treatment would suggest positive evidence for improving pulmonary function.

PURPOSE: Sitting with crossed legs may have an effect on maintaining a healthy body posture and proper functioning of the respiratory system. Thus, this study's objective was to identify whether or not sitting with crossed legs affects the vertebral angle, chest wall mobility, the pulmonary function, and the activity of the respiratory muscles. METHODS: Thirty healthy subjects were recruited for this study (16 males and 14 females). The vertebral angle, chest wall mobility, pulmonary function, and the activity of the respiratory muscle were measured while the subjects sat in the correct posture and these factors were again measured with the subjects seated with their legs crossed. Three-dimensional motion analysis was used to determine the trunk and lumbar vertebral angles. Surface electromyography was employed to measure the sternocleidomastoid, the rectus abdominis, and the external and internal oblique abdominis muscles. A tapeline was utilized to evaluate the subjects' chest wall mobility. Spirometry was assessed to determine the forced vital capacity and forced expiratory volume in one second. Paired t-tests were then performed (p<.05). RESULTS: There were significant differences in the trunk and lumbar flexion angles, the chest wall mobility, the activity of the right external oblique muscle, and the left internal oblique abdominis muscle. However, the difference in pulmonary function did not reach statistical significance. CONCLUSION: A crossed leg posture caused slight thoracic extension and lumbar flexion, which may lead to a decrease of the chest wall mobility and also to an imbalance of the abdominal muscles. Therefore, sitting with a crossed leg posture should be avoided. Yet a crossed leg posture did not have any clinical effect on the pulmonary function of healthy people. It may be necessary to study the effects of sitting with crossed legs over an extended period of time for patients suffering with impaired respiratory function.

PURPOSE: The purpose of this study was to compare how the shoulder height and respiratory function are affected by applying shoulder stabilization exercises and core stabilization exercises that are effective for strengthening the trunk muscles and postural stability for adults with a round shoulder posture (RSP). METHODS: The participants were 28 young adults with RSP. They were assigned randomly to two groups: shoulder stabilization exercise and core stabilization exercise. They performed the exercises for 30 minutes twice a week for four weeks. They measured the shoulder height and respiratory function before and after exercise. RESULTS: No significant difference in shoulder height was found between the groups. A significant decrease in shoulder height was found in the shoulder stabilization exercise group after exercise. The core stabilization exercise group showed a significant decrease after exercise. In respiratory function, no significant difference was found between the groups. The forced vital capacity (FVC) and forced expiratory volume in one second (FEV₁) were increased significantly in the shoulder stabilization exercise group before and after exercise. The FEV₁, FEV₁/FVC, and peak expiratory flow were significantly higher in the shoulder stabilization exercise group after exercise than in the core stabilization exercise group. CONCLUSION: Shoulder stabilization exercise and core stabilization exercise improved the postural alignment and pulmonary function, and the exercises could be helpful in shoulder rehabilitation as well as the clinical part of the treatment of rounded shoulder posture.

Objective: The aim of this study is to explore how using inspiratory training affects the respiratory function and balance of stroke patients. We also plan to compare the results with a control group that does not receive the intervention. Design: A Randomized Controlled Trial Methods: In this study, 27 chronic stroke patients were randomly assigned to either a control group (n=14) or an experimental group (n=13). Both groups underwent six weeks of common interventions involving standard physiotherapy and treadmill training. Additionally, the experimental group received inspiratory training. Respiratory function and balance were evaluated using Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1), Maximal Inspiratory Pressure (MIP), Maximal Expiratory Pressure (MEP), Peak Expiratory Flow (PEF), Five times Sit-to-Stand (FTSTS), Seated Center of Pressure (S-COP), and Timed Up and Go (TUG) tests. Results: Respiratory function and balance were compared within each group before and after intervention. The experimental group, which received inspiratory training, showed significant improvements in FVC (0.26±0.18), FEV1 (0.35±0.32), MIP (11.54±12.39), PEF (1.12±1.52), and TUG (-3.39±2.45) compared to pre-intervention values (p<0.05). When comparing changes between groups post-intervention, the experimental group demonstrated significant increases in FVC, FEV1, MIP, PEF, and TUG compared to the control group (p<0.05). However, there were no significant differences in MEP, FTSTS, and S-COP. Conclusions: The results of this study indicate a positive effect of inspiratory training on chronic stroke patients. These findings suggest that with further research involving a larger sample size and enhanced intervention methods, inspiratory training could be employed positively in the rehabilitation of stroke patients.

연구배경: 횡격막의 운동은 흉부 단순 촬영과 fluoroscopy로 관찰해 왔으나 근래 초음파에 의해서 횡격막의 운동거리와 두께를 측정하는 연구들이 있어왔다. 초음파 검사의 장점을 살펴보면 간편하고 비침습적이며 방사선조사가 없고 재현성과 정확성이 있다는 점을 들 수 있다. 본 연구에서는 이러한 횡격막 운동 측정에 대한 초음파의 장점을 이용하여 정상인과 만성폐쇄성 폐질환 환자에서 횡격막 운동을 조사하고 그 결과를 폐기능 지표들과 비교하였다. 연구방법: 정상 성인 28례(의과대학생 16례, 나이를 고려한 대조군 12례)와 만성폐쇄성 폐질환 환자 17례를 대상으로 각각에서 폐기능 검사, 최대 흡기압, 최대 호기압과 초음파상 횡격막의 이동 거리를 측정하여 비교하였다. 초음파는 Aloka 사의 KEC-620 모델을 이용하였으며 앙와위 상태에서 환자의 쇄골 중심선에 해당하는 부위의 우상복부에 횡으로 3.5MHz 탐촉자를 대고 간을 에코창으로 이용하여 M-mode 상에서 평상 호흡시와 폐활량 호흡 또는 최대 호흡시의 횡격막 이동 거리를 3회 측정하여 그 평균값을 얻었으며 최대 흡기압과 최대호기압은 Chest사의 Vitalopower KH-101을 이용하여 3회 측정하여 그 평균값을 얻었다. 결 과: 정상인에서의 횡격막 이동거리는 평상호흡에는 1.5cm-1.7cm를 보였고 최대호흡시에는 5.7cm-6.7cm를 보였다. 정상인에서의 최대호흡시에 횡격막 이동거리는 $FEV_1$ $FEV_1/FVC$, PEF, PIF, 신장과 유의한 상관관계를 보였으나 다중 희귀분석에서는 $FEV_1$ 만이 유용한 예측지표로 계산되었다. 만성폐쇄성 폐질환 환자에서의 횡격막 이용거리는 평상호흡시에는 $1.5{\pm}0.6cm$로 정상인과 유의한 차이가 없었으나 최대호흡시에는 $3.7{\pm}1.3cm$로 대조군에 비해 유의하게 감소되어 있었다. 만성폐쇄성 폐질환 환자군의 각 병기에 따라 횡격막 이동거리를 비교해 본 결과 최대호흡시 횡격막의 이동거리는 $FEV_1$이 감소할수록 짧은 경향을 보였으나 통계적 의의는 없었다. 만성폐쇄성 폐질환 환자에서의 최대호흡시에 횡격막 이동거리는 연령, PEmax, %FVC와 유의한 상관관계를 보였으나 다중 회귀분석에서는 최대호기압(PEmax)과 연령이 유의한 예측인자로 계산되었다. 결 론: 만성폐쇄성 폐질환 환자의 횡격막 이동거리는 정상인에 비해 유의하게 감소하였으며 최대호기압과 가장 좋은 상관관계를 보였다. 그러나 만성폐쇄성 폐질환 환자에서 횡격막 이동거리는 $FEV_1$과 유의한 상관관계를 발견할 수 없어서 초음파를 통한 횡격막 운동검사가 폐기능 평가의 또다른 생리적 지표로 이용될 수 있음을 시사하였다.
