Objective: To examine the effects of Hyeongbangdojeok-san-gami (荊防導赤散加味方) which has been used in asthmatic patients in Korean Medicine. Methods: Five asthmatic patients were enrolled who had visited Semyung University Korean Medical Hospital from July 1, 2015 to June 30, 2016. They were examined by a pulmonary function test and completed the Quality of Life Questionnaire for adult Korean Asthmatics (QLQAKA) before and after taking Hyeongbangdojeok-san-gami for 3 weeks. All data were analyzed by paired t-tests. Results: After treatment with Hyeongbangdojeok-san-gami for 3 weeks, Forced Expiratory Volume 1 sec (FEV 1.0) improved significantly (p=0.01) and Peak Expiratory Flow (PEF) showed an increase of 20% in results examined by Pulmonary Function Test (PFT). The results of the QLQAKA indicated that the main improvements occurred in theitems associated with theactivity domain. Conclusions: This study suggests that Hyeongbangdojeok-san-gami is effective in improving pulmonary function and quality of life in patients with asthma. More extensive study is needed in the future.

Purpose: The impact of prolonged sitting in a cross-legged posture on physiological factors has not been extensively studied. We therefore attempted to evaluate whether prolonged sitting in a cross-legged posture affects pulmonary function in normal young adults. Methods: Twenty-four participants were recruited in this study, and the participants were equally allocated to the normal sitting posture group (NSP group, n=12) or sitting posture with the cross-legs group (SPCL group, n=12). The NSP group sat on chairs without crossing their legs for 30 minutes, and the SPCL group sat on the chair with legs crossed (the right knee on the left knee or the left knee on the right knee) for 30 minutes. The pulmonary function of the subjects was evaluated based on forced vital capacity (FVC), forced expiratory volume in one second (FEV1), FVC/FEV1, and peak expiratory flow (PEF) measured using a spirometer. Results: In the intra-group comparison, the SPCL group showed significant differences in FVC and FEV1 before and after sitting (p<0.05), but no significant differences (p>0.05) were observed in the NSP group. However, there were no significant differences between the two groups in the pulmonary function parameters measured before and after sitting (p>0.05). Conclusion: Our results confirmed that prolonged sitting in a cross-legged posture could have a negative influence on pulmonary function. Therefore, if a sitting position is maintained for a long time, the correct sitting posture should be maintained to prevent musculoskeletal disorders as well as to maintain normal pulmonary function.

Background: This study was aimed to determine the effects of deep abdominal muscle exercises (DAME) and thoracic mobility exercises (TME) on pulmonary function. Methods: This study was conducted with 22 college students who are in their 20s and have no problem carrying out activities of daily living. All subjects were randomly assigned to either the DAME group (11) or the TME group (11) to undertake the exercises for 2 weeks. To measure pulmonary function of subjects, forced vital capacity (FVC), forced exploratory volume in 1 second (FEV1) and peak expiratory flow (PEF) were measured using chest graph. Chest expansion of subjects was also measured with tape ruler. These measurements were performed on the first day before the exercise program started and on the next day after the 2-week exercise program was completed. A paired-t test was performed to compare the differences in pulmonary function before and after the exercise program, and an independent t-test was performed to compare the two groups. Results: The results of this study were as follows: 1) In comparison of pre- and post-exercise changes in the DAME and TME groups, both groups showed significant increase in chest expansion and PEF after the exercise program, compared with the baseline data (p<.05). Both groups also demonstrated improvements in FVC and FEV1 after the exercise program, compared with the baseline data. However, the differences were not statistically significant (p>.05). 2) The comparison of the DAME and TME groups revealed no significant differences in chest expansion, FVC, FEV1 and PEF (p>.05). Conclusion: It is therefore concluded that both DAME and TME were effective in improving pulmonary function.

PURPOSE: The purpose of this study was to investigate the immediate effects of inspiratory muscle training on diaphragm movement and pulmonary function in healthy women. METHODS: The subjects of the study were 27 young women between ages 19 and 22 years who had no history of orthopedic damage for the last 6 months. The 27 participants were randomly selected and spontaneously participated and consented to the purpose of the study. This study measured diaphragm movement and pulmonary function under two different conditions, before and after inspiratory muscle training. Ultrasonography is appropriate for measuring diaphragm movement, and Pony Fx is appropriate to measure pulmonary function such as forced vital capacity (FVC), forced expiratory volume in 1 second ($FEV_1$), $FEV_1/FVC$ ratio, and peak expiratory flow (PEF) before and after inspiratory muscle training. Paired t-test with a significant level of .05 was used for statistical analysis. RESULTS: As a result, diaphragm movement significantly increases 1.45cm from before inspiratory muscle training (p<.05). Also, FVC, $FEV_1$, and FEP significantly increase 11.25%, 6.96%, and 8.18%, respectively, from before inspiratory muscle training (p<.05). CONCLUSION: The diaphragm movement and pulmonary function of the healthy women in this study were in stantly affected by inspiratory muscle training. From these results, we need to confirm effects of inspiratory muscle training on clinical patients such as pulmonary disease.

Background: Inhalation of asbestos fibers can lead to adverse health effects on the lungs. This study describes lung function profiles among individuals with nonmalignant asbestos-related disorders (ARDs). Methods: The study population was from the Workers' Compensation (Dust Diseases) Board of New South Wales, Sydney, Australia. Lung function measurements were conducted in males with asbestosis (n = 26), diffuse pleural thickening (DPT; n = 129), asbestosis and DPT (n = 14), pleural plaques only (n = 160) and also apparently healthy individuals with a history of asbestos exposure (n = 248). Standardized spirometric and single-breath diffusing capacity for carbon monoxide ($DL_{CO}$) measurements were used. Results: Mean age [standard deviation (SD)] was 66.7 (10.3) years for all participants. Current and ex-smokers among all participants comprised about 9.0% and 54.8%, respectively. Median pack-years (SD) of smoking for ex- and current-smokers were 22.7 (19.9). Overall 222 participants (38.6%) and 139 participants (24.2%) had forced expiratory volume in 1 second ($FEV_1$) and forced vital capacity (FVC) measurements < 80% predicted, and 217 participants (37.7%) had $FEV_1/FVC$ results < 70%. A total of 249 individuals (43.8%) had DLCO values < 80% predicted and only 75 (13.2%) had DLCO/VA results < 80% predicted. A total of 147 participants (25.6%) had peak expiratory flow (PEF) measurements < 80% predicted. The presence of ARDs lowered the lung function measurements compared to those of healthy individuals exposed to asbestos. Conclusion: Lung function measurement differs in individuals with different ARDs. Monitoring of lung function among asbestos-exposed populations is a simple means of facilitating earlier interventions.

PURPOSE: This study was conducted to investigate the effect of the resistance respiratory muscle exercise with transcutaneous electrical nerve stimulation (TENS) on the respiratory muscle tone and pulmonary function of stroke patients. METHODS: Twenty stroke patients were divided into the TENS group (n = 7), placebo TENS group (n = 7), and control group (n = 6), and each intervention was performed on the three groups 5 times a week for 4 weeks. The assessment was carried out by measuring changes in the muscle tone of the latissimus dorsi and abdominal external obliques, and pulmonary function. RESULTS: In this study, the TENS group and the placebo TENS group had significant increases in the paretic side latissimus dorsi muscle tone, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and peak expiratory flow (PEF). There was no significant difference in changes in respiratory muscle tone between the three groups. The pulmonary function was significantly different between the three groups, and it was observed from the results of the post-hoc test that FVC showed a significant increase in the TENS group and the placebo TENS group compared to the control group. CONCLUSION: Through this study, it was found that the respiratory muscle resistance exercise was more effective as a method to increase respiratory muscle tone and pulmonary function in stroke patients than combined transcutaneous electrical nerve stimulation.

Objective: This study aims to assess the reliability and validity of the new hand-held spirometer as a potential substitute for traditional pulmonary function testing (PFT) devices. Design: Cross-sectional study. Methods: In this study, thirty healthy adults underwent spirometry using both the new hand-held spirometer and the MIR spirometer, which is a standard PFT device. Parameters including peak expiratory flow (PEF), forced expiratory volume in one second (FEV₁), and forced vital capacity (FVC) were measured and analyzed for validity and reliability. Inter-rater reliability and validity were evaluated through 95% limits of agreement (LOA) and intraclass correlation coefficients (ICC). Statistical analyses, including the Bland-Altman plots and the ICC, were utilized to assess agreement between the two devices. Results: The new hand-held spirometer exhibited a good agreement with intra-class coefficient (ICC [2,1]) ranging 0.762 to 0.956 and 95% LOA of -1.94 to 1.80 when compared with MIR. The test-retest reliability of the hand-held spirometer analyzed using - ICC [2,1] demonstrated a good level of consistency (ICC [2,1] =0.849-0.934). Conclusions: In conclusion, the study aimed to assess the potential of the new hand-held spirometer as a viable alternative to traditional PFT devices, with a specific focus on its reliability and validity in spirometric measurements. The new hand-held spirometer exhibited good test-retest reliability across all measured variables, suggesting its potential as a valid and reliable tool for simultaneous PFT measurements.
