  • Background: Panting method for airway resistance measurement has the disadvantages of departing from the normal breathing pattern and of difficult for some patients to perform. We can measure airway resistance during quiet breathing under more physiologic conditions. Airway resistance is often measured during panting but attempts have been made to facilitate resistance measurements during quiet breathing. This study was designed to compare airway resistance measurements during panting with those during quiet breathing. Method: The 24 normal persons and 29 pulmonary disease patients were included in this study. Spirometry was performed and airway resistance measurement was also done during panting and quiet breathing concomittently. Results: The results were as follows; 1) High correlations were found between airway resistance measurements during panting and quiet breathing. 2) Resistance fell during panting, 21.2% in Raw tot, and 22.1% in Raw 0.5. 3) In normal persons, airway resistance fell more during panting when comparing to those in pulmonary disease patients. 4) This was largely independent of thoracic gas volume differences, because the specific airway conductance rose significantly during panting 5) The patients in whom resistance didn't fell during panting was supposed to the patients who couldn't perform panting successively because of high resistance. Conclusions: Although airway resistance can be measured during panting or quiet breathing according to the patient's performance, we must consider resistance fell during panting, by a mean 20%. It may be concluded that quiet breathing is more likely than panting to provide a relevant measurement of airway resistance.

  • Abdominal muscle plays a crucial role in postural control and respiration control. However, thickness of abdominal muscle in the paretic side of a hemiplegic patient has not been reported in previous studies. The purpose of this research was to compare lateral abdominal muscle thickness between the nonparetic and paretic side in patients with chronic stroke using rehabilitative ultrasound imaging. Twenty two patients with chronic stroke participated in this study. Absolute thickness of transversus abdominis (TrA), internal oblique (IO) and external oblique (EO) was measured at the end of inspiration and expiration during quiet breathing, and relative thickness was calculated (thickness of each muscle as a percentage of total muscle thickness). Ultrasound imaging was recorded three times and the average value was determined for statistical analysis. Differences in absolute and relative lateral abdominal muscle thickness between the nonparetic and paretic side were assessed with paired t-tests. Absolute muscle thickness of the paretic side TrA was thinner than that of the nonparetic side at the end of inspiration and expiration during quiet breathing. Relative muscle thickness of the paretic side TrA was thinner than the paretic side only at the end of expiration during quiet breathing (p>.05). Therefore, it is necessary to strength TrA in patients with chronic stroke during physical therapy intervention. Further study is needed whether physical therapy intervension will induce TrA thickness in patients with chronic stroke in prospective study design.

  • T'oegye placed great emphasis on the cultivation of quiet-sitting. His idea of quiet-sitting, like Zhu Xi's, had various therapeutic effects as well. This can be highlighted as a real-life practice and a diverse application of the "abiding by Gyong" that he stressed; it is also associated with the treatment of physical diseases, composure in the mind, the benefits of reading, meditation in solitude, and many other areas. And We can easily infer that T'oegye would have set some premises before referring to Hualin Simbang. First, he would have been wary of quiet-sitting being the goal of cultivation: Too much obsession with and emphasis on Toinsul would actually obstruct the practice of "abiding by Gyong" and mislead one's effort for the "preservation and nourishment of the mind" and "reflection and examination." T'oegye would have probably used the physical and breathing exercises in Hualyin Simbang mainly as a reference to treat his physical illnesses. Also, his Toinsul would have been employed independently and partially as a sort of supplementary practice-without being used in parallel with quiet-sitting as one of the methods to achieve reverent seriousness.

  • Breathing is essential for life and at the same time takes a role as a antidote for stress. In the Orient, it was recognized early that respiration, mind, and body have a relation that is inseparable and therefore proper breathing is so important. However, since the mechanism of therapeutic effect by breathing have not been verified, the treatment has been continued till recent years. From that which originated in the Orient, several techniques in the west have been developed to regulate breathing, and have been applying to the clinical situation and to studies, however scientific studies are still lacking. Recently, relaxed breathing has been used as an efficient strategy for breathing therapy as it has an effect on reducing physiological tension and arousal, and, therefore can be used as a basic technique to control or manage stress. In this study, in order to provide basic information and guidelines for clinical application, which will aid in the application of the theoretical basics of breathing therapy and its technique, a review of the literative was conducted. The findings are as follows: 1. Since proper breathing not only has, physically, the important function in supplying oxygen to the body but also gives a good emotional, or pleasant state of mind, it is the first step in controlling physical and mental health. 2. The basic types of breathing can be classified into two types; ‘diaphragmatic breathing(relaxed breathing)’ and ‘chest breathing(stress breathing)’. In yoga type breathing, there are four kinds of breathing, ‘upper breathing’, ‘mid breathing’, ‘down breathing’, and ‘complete breathing’. 3. The theoretical explanation of the positive thera peutic effect of breathing therapy techniques exemplifies good brain function, sufficient air flow through the nasal passages, diaphragmatic movement, light vagal stimulation, CO2 changes and cognitive diversion but in most studies, the hypothesis of CO2 is supported. 4. The technique of breathing is designated with many names according to the muscles and techniques used for breathing, and for control of stress, diaphragmatic breathing(relaxed breathing) is explained as a basic technique best used to manage of stress. 5. The relaxed-breathing includes slow diaphragmatic breathing, breath meditation, nasal breathing, yogic abdominal breathing, Benson's relaxed response, and quiet response.

  • Purpose: The purpose of this study was to investigate whether changes in electromyography (EMG) activations of spinal stability muscles with respiratory demand change were due to changes in respiratory demand or in postural demand. Methods: Forty healthy subjects (19male, 21female, $20.8{\pm}1.9$years old) performed quiet breathing and four different forced respiratory maneuvers (FRM) (Pulsed Lip Breathing, Diaphragmatic Breathing, Combination breathing, and respiratory muscle endurance training breathing) while in sitting and standing positions. EMG data for four muscles (TrA/IO, EO, RA, and ES) were collected and filtered using a band pass filter (20~200Hz) and a notch filter (60, 120, 180Hz). Results: There were no significant differences on percentage of change on %MVIC between QB and FRM (PLB, CB, DB, and RMET) between positions (all p>0.05).

  • Background: Research efforts to improve the pulmonary function of people with limited chest function have focused on the diaphragmatic ability to control breathing pattern. Real-time ultrasonography is appropriate to demonstrate diaphragmatic mechanism during breathing. Objective: The purpose of this study was to investigate the effects of diaphragmatic breathing training using real-time ultrasonographic imaging (RUSI) on the chest function of young females with limited chest mobility. Methods: Twenty-six subjects with limited chest mobility were randomly allocated to the experimental group (EG) and control group (CG) depending on the use of RUSI during diaphragmatic breathing training, with 13 subjects in each group. For both groups, diaphragmatic breathing training was performed for 30-min, including three 10-min sets with a 1-min rest interval. An extra option for the EG was the use of the RUSI during the training. Outcome measures comprised the diaphragmatic excursion range during quiet and deep breathing, pulmonary function (forced vital capacity; FVC, forced expiratory volume in 1-sec; FEV1, tidal volume; TV, and maximal voluntary ventilation; MVV), and chest circumferences at upper, middle, and lower levels. Results: The between-group comparison revealed that the diaphragmatic excursion range during deep breathing, FVC, and middle and lower chest circumferences were greater at post-test and that the changes between the pretest and post-test values were greater in the EG than in the CG (p<.05). In addition, the subjects in the EG showed increased post-test values for all the variables compared with the pretest values, except for TV and MVV (p<.05). In contrast, the subjects in the CG showed significant improvements for the diaphragmatic excursion range during quiet and deep breathings, FVC, FEV1, and middle and lower chest circumferences after the intervention (p<.05). Conclusion: These results indicate that using RUSI during diaphragmatic breathing training might be more beneficial for people with limited chest mobility than when diaphragmatic breathing training is used alone.

  • Background: This study was to determine whether the diaphragmatic breathing exercise using a DiP Belt(Diaphragmatic Pressure Belt) is effective in increasing the diaphragmatic motion and forced vital capacity. Design: Pretest-Posttest design. Methods: A total of 44 subjects(15 male, 29 female) participated in this study. All subjects were measured the diaphragmatic motion with a sonography and the Forced Vital Capacity(FVC) was measured with a digital spirometer. After 4 weeks, the subjects were intervened the diaphragmatic breathing exercise using a DiP belt and were remeasured for diaphragm motion and FVC. Results: After exercise intervention, quiet breathing significantly increased with the change in diaphragmatic motion and showed a moderate effect size (p<.01, Cohen's d = -0.53). In addition, it was significantly increased in deep breathing and showed a high effect size (p<.001, Cohen's d = -1.32). The mean diaphragmatic contraction pressure increased, but there was no significant difference and the peak diaphragmatic contraction pressure increased significantly (p<.05). Both diaphragmatic contraction pressure showed small effect sizes (respectively Cohen's d = -0.28, -0.33). In spirometry, FVC, Forced Expiratory Volume in 1 second (FEV1), and FEV1/FVC% all increased, but there was no significant difference. Only peak expiratory flow increased significantly and showed a small effect size (p<.05, Cohen's d = -0.41). Conclusion: The DiP belt diaphragmatic breathing exercise that the principle of visual feedback can correct diaphragm breathing in a short time, so it is a useful breathing exercise device that can help the diaphragm breathing exercise in the right way in clinical practice.

  • Background: Airway resistance(Raw) is measured with the body plethysmograph by displaying the relationship between airflow and alveolar pressure($V/P_A$). If the resistance curve on $V/P_A$ tracing is curved or looped, the estimation of Raw is difficult. This study was designed to examine wheather there is any correlation between the shape of resistance curve and the clinical status and the pulmonary function of patients. Methods: The 146 pulmonary disease patients with increased Raw were included in this study. The shapes of resistance curves on $V/P_A$ tracing with body plethysmograph during quiet breathing were analyzed and compared with pulmonary function. Results: The results were as follows ; 1) The shapes of resistance curves were summarized in 5 categories; type 1: linear, type 2: ovoid, type 3: sigmoid, type 4: scoop, type 5: paisley. The type 3 except 1 case, type 4 and type 5 were found to have loop mainly in expiratory phase. 2) Although the shapes of resistance curves were not typical for specific disease, the resistance curves of acute disease tended to belong to type 1 or 2 and those of chronic airflow obstruction tended to belong to type 3, 4 or 5. But resistance curves of bronchial asthma and destructive lung with tuberculosis showed all types in proportion to degree of airflow obstruction or destruction of parenchyme. 3) In the cases of resistance curves going to type 5 rather than type 1 and those with looping, airflow obstuction tended to be severe and airway resistance and residual volume tended to increase. Conclusions: Analysis of resistance curve on $V/P_A$ tracing measuring airway resistance is helpful for judging degree of airflow obstruction and air trapping. Although the shape of resistance curve is not typical for specific disease, there is a close association between looping and airway obstruction.

  • To perform a long-term ambient sampling study at a residential site, an air sampler was constructed to collect 24-hour integrated air samples suitable for the volatile organic compounds (VOCs) analysis. It includes an esthetically acceptance due to proximity to homes, as fell as providing the required sampling specifications. The VOCs sampler accomodates four 5/8 "stainless steel(SS) traps packed with adsorbent(Tenax) and is capable of four flow rates in the range of 5 to 50 cc/min. Sintered metal filters(10 micrometer) were directly connected to the inlet of the trap adapters. Additional specifications include: 1) constructed of organically inert materials, 2) weatherproof, 3) battery operated, 4) collecting of VOCs at a breathing zone level, and 5) quiet operation with micro diaphragm pumps wrapped by the sponge. The pump/battery system was separated from the sampling shelter. Sound levels measured for this system were below permissible sound levels (NJDEP) at a residential site. The sampler has been successfully operated at both ground level in a residential area and on the roof of a one story elementary school.hool.

  • Lung hernia is defined as a protrusion of lung parenchyma beyond the confines of the musculoskeletal thorax. To date, less than 300 cases have been reported in the literature. The patients were 37 & 57-year-old men who had traumatic rib fractures in the past, whose chief complaint was a painless soft bulging mass increased in size during expiration or coughing and diminished during inspiration or quiet breathing. The primary repair was performed without any p stoperative recurrance. We report two cases of acquired herniation of lung first time in Korea with a brief review of literature.
