The purpose of this study was to evaluate the change of functional ambulation profile(FAP) and temporal-spatial gait parameters in hemiplegic patient by forceful respiratory exercise. 28 Hemiplegic patients due to stroke was randomized in 3 groups, forceful expiratory training(FET), forceful inspiratory training(FIT) and control group. In the experimental groups, ordinary physical therapy with forceful expiratory training and forceful inspiratory training for 20 minutes duration 3 times per week for 6 weeks were respectively performed. In the control group, only ordinary physical therapy was done. FAP and temporal-spatial gait parameters was measured at before and after experiments. The results of this experimental study were as follows : 1. In comparison of FAP before and after experiment, the FAP was significantly increased in the FET and FIT group (p<.01). In comparison of difference of FAP among 3 groups, there was the significant difference between the FIT group and the control group (p<.05). 2. The results of temporal-spatial gait parameters are as follows : 1) In comparison of gait velocity before and after experiment, the gait velocity was significantly increased in the FET and FIT group (p<.05). In comparison of difference of the gait velocity among 3 groups, there was the significantly difference between the FIT group and the control group (p<.05). 2) In comparison of gait cadence before and after experiment, the gait cadence was significantly increased in FIT group (p<.05). In comparison of the difference of the gait cadence among 3 groups, there was no significant difference between the FIT group and the control group (p>.05). Based on these results, it is concluded that the forced respiratory exercise program for 6 weeks can be improve the FAP and temporal-spatial gait parameters in hemiplegic patients. Therefore, the forced respiratory exercise is useful to improve the walking ability in hemiplegic patients.

This study was conducted to investigate the effects of whole body vibration stimulation training combined with respiratory resistance on respiratory and balance function in stroke patients. 17 patients with chronic stroke were randomly assigned to the experimental group (n = 8) and the general vibration exercise program (n = 9). The intervention was conducted three times a week for 30 minutes once a week for 4 weeks. The respiratory function and balance ability were evaluated before and after the intervention to evaluate the degree of functional improvement. As a result, there was a significant difference (p<.05) between the respiratory function and the balance ability in the experimental group, and a significant difference(p<.05) in the respiratory function between the experimental group and the control group. The balance ability was not significantly different among the experimental groups. Through the results of this study, whole body vibration stimulation training combined with respiratory resistance may be useful as a program for improving respiratory function and balance ability of stroke patients.

Background: Several large outbreaks have demonstrated the threat of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in close-contact environments, such as occurs during training and quartering of military recruits training. In South Korea, which is a hospital or healthcare-associated MRSA prevalent area, military service is compulsory for all healthy young men. We surveyed and determined the extent of CA-MRSA colonization in the upper respiratory tracts of Korean military recruits. Methods: The Korean military recruits who were enrolled in a military training facility from November 2004 to March 2005 were eligible for this study. Sputum or nasopharyngeal swap was obtained from randomly selected subjects who displayed upper respiratory tract symptoms. Results: Of the 181 participants, 32 participants (17.7%) were colonized with S. aureus, and 12 participants (6.6%) were colonized with MRSA. Among the cases that were colonized with S. aureus, 37.5% (12/32) were colonized with MRSA. Antimicrobial susceptibility testing showed resistant patterns that were suggestive of the CA-MRSA strains for all of the MRSA isolates. Conclusion: This study of Korean military recruits found a great deal of showed MRSA colonization in them, and the antimicrobial resistant profile that was suggestive of a CA-MRSA strain. Further efforts to prevent the spread of MRSA infections and careful monitoring for CA-MRSA outbreaks are warranted, especially in a high risk group such as military recruits.

PURPOSE: This study investigated the immediate effect of inspiratory muscle training with whole-body vibration on the pulmonary function of subacute stroke patients. METHODS: All participants (n=30) were allocated to the following groups: (1) the inspiratory muscle training group with whole-body vibration (n=10), wherein the patients received inspiratory muscle training with whole-body vibration comprising 3minutes of vibration per session and respiratory training of 30 times and 2 sessions for one day. (2) the inspiratory muscle training group with visual feedback (n=10), wherein the patients received inspiratory muscle training with visual feedback. (3) the inspiratory muscle training group (n=10), wherein the patients received inspiratory muscle training. RESULTS: After the experiment, the inspiratory muscle training group with whole-body vibration exhibited significantly higher forced vital capacity, forced expiratory volume at 1 second, peak inspiratory flow rate, maximal inspiratory pressure, and chest expansion (p<.05), compared to the other groups. Inspiratory muscle training group with whole-body vibration had significantly higher peak expiratory flow rate and maximal voluntary ventilation than the other groups (p<.05). CONCLUSION: These results show that pulmonary function, maximal inspiratory pressure, and chest expansion were significantly better in the inspiratory muscle training group with whole-body vibration than in the other groups. Thus, this treatment will help recovery of pulmonary function in stroke patients.

Objective: The interest of clinicians is increasing due to the newly established medical insurance for pulmonary rehabilitation. Improvement of respiratory muscle strength and pulmonary function is an important factor in pulmonary rehabilitation, and this study aims to investigate the correlation between changes in respiratory muscle contraction thickness that can affect respiratory muscle strength and pulmonary function. Design: Cross-sectional observational study. Methods: Thirty-one subjects (male=13, female=18) participated in this study. The respiratory muscle strength was measured by dividing it into inspiratory/forced expiratory muscles, and the pulmonary function was measured by forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and FEV1/FVC. To evaluate the respiratory muscle length increase, in resting and concentric contraction thickness of diaphragm, external/internal oblique, transverse abdominis, and rectus abdominis were measured by using ultrasonography. Results: Inspiratory muscle strength showed a significant correlation with the length increase of the inspiratory muscle (r=0.368~0.521, p<0.05), and forced expiratory muscle strength showed a significant correlation with length increase of forced expiratory muscle (r=0.356~0.455, p<0.05). However, pulmonary function was not correlated with the length increase of the respiratory muscle. Conclusions: In this study, a correlation between respiratory muscle strength and respiratory muscle length increase was confirmed, but no correlation with the pulmonary function was found. It is considered that the respiratory muscle strength can be improved by increasing the respiratory muscle thickness through appropriate respiratory muscle training.

Purpose : The purpose of this study was to investigate the impact of postural correction training on pulmonary function on 28 college students suspected of turtle neck syndrome, and the following conclusions were obtained. Methods : Turtle neck syndrome suspicion 28 person were randomly divided into a posture training group (n = 14) and group that does not perform posture training (n = 14). Respiratory function was measured by SPIROVIT SP-1 and respiratory gas analyzer. The posture training group performed balloon blowing and stair climbing after 20 minutes of posture training, and the group without posture training carried out balloon blowing training and stair climbing. Five times a week and for two weeks. Results : 1. The comparison of the FVC before and after experiments caused by balloon blowing showed a higher level of effortful pulmonary function in the control group than in the experimental group. 2. Comparison of PEFs before and after the experiment by balloon blowing showed that the experimental group's peak flow rate was higher than that of the control group. 3. Comparison of the FIVC before and after experiments with balloon blowing showed that the comparison of the FIVC showed a higher level of effortless intake pulmonary function in the control group than in the experimental group. 4. The comparison of the maximum ventilation volume(VE) before and after the experimental gas measurement showed that the maximum ventilation rate of the experimental group was higher than that of the control group. 5. The comparison of pre-test and post-test heart rate(HR) by breath gas measurement showed that the heart rate of the control group was higher than that of the experimental group. Conclusion : the results of this study showed that postural correction training, balloon blowing training, and stair climbing could have a positive impact on improving pulmonary function. However, the two-week experiment conducted five times a week showed an increase in pulmonary function, but it was difficult to see the effect due to the short study period. Therefore, it is hoped that later studies will be conducted more systematically on the effects of breathing exercises on improving pulmonary function after post-postural correction training for patients with pulmonary function problems.

Purpose : The purpose of the study was to examine if a respiratory muscle strengthening training in patients with stroke can improve their pulmonary function. Methods : Volunteers were included for the study if a patient diagnosed stroke more than 6 months and had 24 points or higher in MMSE-K scores. Twenty-eight subjects participated in this study and were randomly divided into two groups; a breathing exercise group(n=14) and a control group(n=14). The intervention for all subjects was conducted for 20minutes, three times a week for 4 weeks. Subjects for the breathing exercise group had the respiratory muscle strengthening training using spiro-tigers, where-as subjects in the control group got their usual treatment ie a postural training. The six-minute walking test(6MWT) and the pulmonary function tests(FVC, $FEV_1$, $FEV_1$/FVC, VC, Vt, IRV and ERV) were employed to assess treatment effects at baseline and after their intervention. Results : Twenty-four subjects finished their 4-week treatment programs. The general characteristics between groups were found to be similar (p>0.05). The pulmonary function between groups were also observed no difference across groups at the baseline measurement (p>0.05). In the post treatment group comparison, subjects in the breathing exercise group showed an increase in lung function with VC ($2.73{\pm}0.80{\ell}$) and Vt ($0.87{\pm}0.38{\ell}$) than those in the control group ($1.91{\pm}0.80{\ell}$ and $0.48{\pm}0.22{\ell}$ respectively) (p<0.05). However, there was no difference found in 6MWT, FVC, $FEV_1$, $FEV_1$/FVC, IRV, and ERV across groups (p>0.05). Conclusion : A significant increase in VC and Vt was found in subjects with stroke, who had four-week training on respiratory muscle strengthening. However, respiratory muscle strengthening showed no effect on walking speed and FVC, $FEV_1$, $FEV_1$/FVC, IRV, and ERV in patients with stroke.
