PURPOSE: This study examined the effective impact of self and resistive and ultrasound-biofeedback diaphragm breathing on the pulmonary function and diaphragm thickening ratio of young adults. METHODS: Thirty normal adults were assigned randomly to three experimental groups (self- diaphragm breathing (n=9), resistive-diaphragm breathing (n=11), ultrasound-biofeedback diaphragm breathing (n=10)). Each group participated for 15 minutes for times with a two minute rest between two sets. The subjects were assessed using the pre- and post- diaphragm thickening ratio and the pulmonary function (forced vital capacity, forced expiratory volume at one second, maximal voluntary ventilation, and respiratory rate) on the thirty subjects. A paired t-test was to determine the difference between before and after the experiment in each group of diaphragm breathing before and after the exercises. One-way ANOVA was used to determine the differences between the groups. RESULTS: The forced vital capacity and maximal voluntary ventilation measurements revealed a significant difference in the resistive-diaphragm breathing group than the other two groups. On the other hand, there was no significant difference between the self-diaphragm breathing and ultrasound-biofeedback breathing groups. CONCLUSION: The resistive-diaphragm breathing group showed greater improvement in the pulmonary function than the other two groups. Therefore, resistive-diaphragm breathing will improve the pulmonary function on normal young adults.

PURPOSE: This study attempts to examine the impact of respiratory muscle exercises on the respiratory function and quality of sleep among stroke patients. METHODS: A total of 20 stroke patients were randomly divided into a breathing-exercise training group(n=10) and a breathing-device-training group(n=10). Changes in pulmonary function, as well as the quality, were measured before and after the intervention. The breathing exercise was performed three times a week for a total of eight weeks. Breathing-device exercises made use of a lung-capacity-strengthening device and were performed for three times a week for eight weeks. One Flow FVC was used as a measurement tool for the pulmonary function test. The Pittsburgh Sleep Quality Index(PSQI) and a sleep measurement tool were used for sleep evaluation. RESULTS: In a comparison of changes in pulmonary function before and after the training, the breathing-exercise group and the breathing-device-training group showed a significant difference. In changes of sleeping measure and PSQI, the breathing-exercise group and the breathing-device-training group also showed significant differences. CONCLUSION: Diverse index analyses confirmed that breathing exercises and exercises using a lung-capacity-strengthening device, were effective in improving respiratory function and quality of sleep among stroke patients experiencing respiratory function disorders and sleep disorders.

Background: Patients with stroke have core muscle weakness and limited rib cage movement, resulting in restrictive lung disease. Objectives: To examine the comparison of effects of rib cage joint mobilization combined with diaphragmatic breathing exercise and diaphragmatic breathing exercise on the pulmonary function and chest circumference in patients with stroke. Design: A cluster randomized controlled trial. Methods: Twenty-four patients were randomly assigned to an experimental group (rib cage joint mobilization combined with diaphragmatic breathing exercise group) and control group (diaphragmatic breathing exercise group). Patients in the experimental group underwent rib cage joint mobilization for 15 min and diaphragmatic breathing exercise for 15 min. The control group underwent diaphragmatic breathing exercise for 30 min. Both groups underwent exercise thrice a week for 4 weeks. The pulmonary function and chest circumference were measured using the MicroLab spirometer and a tape measure, respectively. Results: After the intervention, the pulmonary function and chest circumference significantly improved in both groups. These improvements were significantly higher in the experimental group than those in the control group. Conclusion: Rib cage joint mobilization combined with diaphragmatic breathing exercise improves pulmonary function and chest circumference in patients with stroke.

Purpose: This study investigated the effect of virtual reality and Schroth breathing exercises on the lung function characteristics of normal adults in their 20s. Methods: The subjects were randomly divided into groups with ten people each in the experimental groups, namely the virtual reality breathing exercise group (BBEG) and the Schroth breathing exercise group (SBEG), and the control group. The experimental groups performed each breathing exercise for 4 weeks. Subsequently, pulmonary function test indicators such as the forced vital capacity (FVC) and the forced expiratory volume (FEV1) were measured. Results: In the within-group comparison of the subjects before and after the exercises, there was a significant difference in the FVC and FEV1 (p<0.05), but there was no significant difference in FEV1/FVC. The result of the difference test between groups showed that there was a significant difference in FEV1/FVC after exercise (p<0.05). However, there were no significant differences in the remaining items (p>0.05). Conclusion: Improvement in lung function was seen in both exercise groups, and the changes in FEV1/FVC indicated significant improvement in the lung function of the experimental groups compared to the control group.

Purpose : It was to compare changes in respiratory function (pulmonary function, inspiratory function) after four weeks of inspiratory muscle strengthening training (diaphragmatic breathing with upper arm exercise, Power-Breathe breathing) for 36 healthy people. Methods : Subjects were randomly assigned to diaphragmatic breathing with upper arm exercise (Group I) and Power-breathe breathing (Group II) was conducted by the protocol for four weeks five times per week. As the main measurement method for comparison between groups For pulmonary function, Forced Vital Capacity (FVC) and Forced Expiratory Volume at One second (FEV1) were used, and for inspiratory function, Maximum Inspiratory Capacity (MIC), Maximum Inspiratory Pressure (MIP), and Maximum Inspiratory Flow Rate (MIFR) were used. Results : In changes in pulmonary function between groups, FVC and FEV₁ showed no significant difference, and in inspiratory function changes, MIC showed no significant difference, but in MIP and MIFR, Group B significantly improved over Group A. Conclusion : The progressive resistance training using the Power-breath device applied to the inspiratory muscle did not show a significant difference in the increase in the amount of air in the lungs and chest cage compared to the diaphragmatic breathing training accompanied by the upper arm exercise. However, by increasing the air inflow rate and pressure, it showed a more excellent effect on improving respiratory function.

PURPOSE: This study examined the effects of breathing exercise in the water on the pulmonary function and maximum phonation time in children with cerebral palsy. METHODS: The subjects were 24 children with cerebral palsy at GMFCS levels I-III, who were allocated randomly to either the aquatic breathing exercise group or general breathing exercise group 12 subjects per group. Each subject was required to complete 40 minutes of exercise twice a week for eight weeks. Those in the aquatic breathing exercise group performed aquatic breathing exercise, whereas those in the general breathing exercise group performed general aquatic exercise. RESULTS: Significant differences in $FEV_1$, PEF, VC, TV, ERV, and maximum phonation time were observed in the aquatic breathing exercise group after intervention, but there were no significant differences in either FVC, $FEV_1/FVC$, IC, or IRV. In the general breathing exercise group, there were no significant differences in the FVC, $FEV_1$, $FEV_1/FVC$, PEF, VC, IC, TV, IRV, ERV, and maximum phonation time after intervention. In terms of the pulmonary function, the two groups showed a significant difference in the change in $FEV_1$, PEF, and TV after intervention, but not in the FVC, $FEV_1/FVC$, VC, IC, ERV, IRV, and maximum phonation time. CONCLUSION: These results above show that aquatic breathing exercise training in water is more effective in improving the pulmonary function than general breathing exercise training.

Objective: This study was performed to investigate the effects of thoracic joint mobilization and breathing exercises on diaphragmatic thickness, chest expansion, respiratory function, and endurance in patients with chronic stroke. Design: Randomized controlled trial Methods: The study included 24 chronic stroke patients who were randomly divided into two groups. The experimental group (12 people) performed 15 minutes of thoracic joint mobility exercises and 15 minutes of breathing exercises, three times a week for 6 weeks, 30 minutes each time. The control group (12 people) received 15 minutes of conservative physical therapy and 15 minutes of breathing exercises, 3 times a week for 6 weeks, 30 minutes per session, the same as the experimental group. The experimental and control groups performed the same breathing exercises. To assess training effectiveness, changes in diaphragm thickness, chest expansion, respiratory function, and endurance were measured. Results: As a result, the experimental group exhibited significant improvements in diaphragm thickness, chest expansion, and respiratory function. The endurance mode also displayed significant enhancement (p<0.05), a finding consistent with the control group. However, the experimental group displayed more substantial improvements in non-affected diaphragm thickness and thoracic expansion compared to the control group (p<0.05). Conclusions: Drawing from these findings, breathing exercise which combine thoracic mobilization, will be actively utilized in addition to physical therapy interventions in clinical trials as an effective intervention method.

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: This study was conducted in order to determine the changes in pain and breathing function when kinesio taping is applied to patients with myofacial trigger points on sternocleidomastoid (SCM) muscle. Methods: The subjects were 25 males and females aged 20 to 30 years (male 10, female 15). They were randomly divided into the control group and the experimental group to be applied with kinesio taping. Kinesio taping was applied to SCM muscle three times per week for two weeks. Pain triggered when the taut band or nodule was palpated was measured. Pain intensity was measured using the visual analog scale (VAS). The breathing function was measured using forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), and FEV1/FVC ratio. In all subjects, VAS, breathing function was measured before and after intervention. Results: In the experimental group, pain in the SCM was relieved as VAS showed a significant decrease and FVC, FEV1, and FEV1/FVC ratio showed a significant increase. Comparison between the groups, showed significant differences in VAS and the FVC, FEV1, and FEV1/FVC ratio. Conclusion: These results suggest that myofascial pain on SCM muscle is thought a factor that affects the breathing function.
