Using stretch sensors, a stuttering treatment training device that improve the abnormal breathing of stutterer was designed and developed. To improve stutterer's inadequate breathing method that is one of principal reason of stammering, the device estimates breathing method by checking the changes of the stretch sensor's resistances those are put on the chest and abdomen of user. And a vocal exercise program that carry out exercises only when the user maintains the abdominal breathing was designed. Using a PIC16C711 device that includes an A/D convertor, a main controller was designed and the vocal exercises software was developed using Director and C program with graphic user interface for user convenience. The controller sends the resistance data of sensors to PC through the serial port and the software verifies the breathing method. And the device was designed that the RTS (request to send) pin of serial port in PC is used as a power source so that it can work without any battery or other power source. Three stutterers have carried out the clinical experiments using the implemented device for two months and the results showed it was excellent to alleviate the stuttering.

Background: The consequences of disordered breathing patterns are not only distressing to the patient but also expensive to our health care systems if they are not diagnosed and treated. So we performed this study to investigate clinical significants trough gigong, yoga and hyperventilation in oriental medicine and westen medicine Method: Voluntary control of respiration is one of the main methods of physical and mental training such as meditation, qigong meditation or Yoga. So, this study focuses on breathing in qigong and yoga. This study appreciates a role that a control of respiration has in physical, mental aspects and searches side-effects in qigong and yoga Conclusions: A control of respiration has a function that manages Jung(精), Qi(氣), Shin(神) in Oriental Medicine. It manages Autonomic Nerve system, Endocrine system and induces natural awareness. So Briging the body and mind work through a control of breathing. Breathing pattern disorder has Damum and Qiher pattern in Oriental Medicine pattern. This disease pattern concearnes ATP metabolism. Qiher is concearned with a mitochondria disorder and Damum is concearned with a products of lactate. we guess that Lactate analysis may be utilized as a diagonostic criteria of Breathing pattern disorder. After this, It needs a study that Lactate analysis is concearned with Breathing pattern disorder as Damum pattern. Result: A control of respiration is related not only breathing but also spiritual and physical state. Joo-hwa-ip-ma as Breathing pattern disorder is smiliar to hyperventilation. HVS is patternated Damum and Qi-Weakness pattern in oriental medicine. Lactate is an important complement that diagonates HVS and will be concearned with Damum.

Purpose: The study aimed to examine the influence of PNF direct and indirect breathing treatments for patients with cervical spinal cord injuries who had breathing problems. Methods: For each cervical spinal cord patient, force vital capacity (FVC), peak expiratory flow, maximum phonation time (MPT), rib cage width, and VAS were measured pre-intervention and four weeks after post-intervention. The indirect method and the direct method were used for interventions. We treated patients with the indirect method using scapular anterior depression pattern, bilateral extensor pattern with rhythmic initiation, and a combination of isotonic. We treated patients with the direct method, applying pressure on the sternum and using rhythmic initiation (hold relax and stretch reflex) for the rib cage. Training occurred for 50 minutes a day and three days per week for four weeks. Results: FVC, MPT, peak expiratory flow, and rib cage width were increased and decreased at the VAS point for rolling after treatment. Conclusion: Patients with cervical spinal cord injuries who had breathing problems felt uncomfortable when they had conversations on a couch. We found that PNF direct and indirect treatments improved rib cage width and breathing functions of patients with cervical spinal cord injuries.

PURPOSE: This study was conducted to analyze the effects of virtual reality inspiratory muscle training and conventional inspiratory muscle training on diaphragm movement and pulmonary function in patients with thoracic restriction. METHODS: This study measured diaphragm movement, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF), and thoracic mobility (upper, middle, and lower trunk) under two different conditions. Forty young women between 19 and 24 years of age who had no history of orthopedic symptoms for the last 6 months were divided into experimental and control groups. The experimental group performed virtual reality inspiratory muscle training and diaphragm breathing, and the control group performed conventional inspiratory muscle training and diaphragm breathing. RESULTS: The control group showed a significant increase in all dependent variables except for lower trunk mobility and PEF. The experimental group showed a significant increase in all dependent variables except for lower trunk mobility. Particularly, the experimental group showed significant increases in diaphragm movement (p<.05), FVC (p<.05), FEV1 (p<.05), and PEF (p<.05) relative to the control group. CONCLUSION: We recommend inspiratory muscle training with a virtual reality program over conventional training to improve diaphragm movement and pulmonary function in patients with thoracic restriction.

Recently, many study of the Kigong, but that is in the point of the view in Taoism and Ki itself. So, it thought that the study in comparison Kigong(Taoism) to Oriental Medicine is insufficient. I thought much of that there are many description of the movement and the effect in the the body in the old book written Taoism, Doinbub(Physical and breathing exercise), and that there are many relation 'the circulation of the Ki to 12 Jung-kyung(12 regular meridians). Then I give a report of the result that the study is compared in Taoism with in Oriental Medicine. The result were as follows ; 1. In the training of Doinbub, the effect is regulating muscle and skeleton, promote wi(constructive) system and ki(superficial) system, promote the ki and blood, strengthen the body resistance and dispel the invading pathogenic factors and preventive treatment. 2. In the training of Doinbub, the movements were much related to 12 regular Meridians and Muscles along the 12 meridians. 3. In the training of Doinbub, the effect were much related to 12 regular Meridians and Muscles along the 12 meridians. 4. It is possible that we set pathological syndrome to Doinbub(Physical and breathing exercise).

Purpose: To improve self-management in elderly people with hypertension, the researcher examined the effects of an abdominal relaxed breathing exercises using biofeedback on blood pressure. These exercises regulate physical response to stress and lessen the activity of sympathetic nerves. Method: A single-experimental pre-and post-test design was used. Eight elderly people with hypertension participated in the study from April, 6 to June, 14, 2000. Biofeedback was done with soft ware by developed by J & J Company (1-410 form for abdominal respiration training). The abdominal relaxed breathing exercises are based on Mason's suggestion (1985) and were modified by Yu & Song(2001). This program consisted of 4 sessions once a week for four weeks. Data were analysed using SPSSPC+(10.0). Result: There was a significant decrease in systolic and diastolic blood pressure over three different times. There was a significant difference in the level of total stress response, overall health and quality of life but no significant difference in the level of emotional condition over three different times. Conclusion: The results of this study will contribute to the development of nursing strategies for the regulation of blood pressure in older people as the exercises are easy to learn and are a nonpharmacologic approach.

There is a growing need for a care system that can continuously monitor, manage and effectively relieve stress for modern people. In recent years, mobile healthcare devices capable of measuring heart rate have become popular, and many stress monitoring techniques using heart rate variability analysis have been actively proposed and commercialized. In addition, respiratory biofeedback methods are used to provide stress relieving services in environments using mobile healthcare devices. In this case, breathing information should be measured well to assess whether the user is doing well in biofeedback training. In this study, we extracted the heart beat interval signal from the PPG and used the oscillator based notch filter based on the IIR band pass filter to track the strongest frequency in the heart beat interval signal. The respiration signal was then estimated by filtering the heart beat interval signal with this frequency as the center frequency. Experimental results showed that the number of breathing could be measured accurately when the subject was guided to take a deep breath. Also, in the timeing measurement of inspiration and expiration, a time delay of about 1 second occurred. It is expected that this will provide a respiratory biofeedback service that can assess whether or not breathing exercise are performed well.

Purpose: The purpose of this study was to assess the effects of breathing techniques on trunk muscle activity and balance during Pilates reformer footwork exercises, comparing results both within and between groups before and after the intervention. Methods: Thirty-one adult women over the age of 20 were selected as subjects for this study. They were divided into a Pilates breathing group (n = 15) and a general breathing group (n = 16) using a randomized control group study design. A surface electromyogram was used to measure muscle activity within and between the groups before and after the reformer footwork exercise. Static balance measurements were taken while standing on two legs, and dynamic balance measurements were taken while standing on one leg. All measurements were taken three times, and the average values were used for analysis. Results: The results of the study showed that muscle activity increased with significant differences in the external oblique and transverse abdominal muscles after exercise in the pre-post comparison within the Pilates breathing group (p < 0.05). In the between-group comparison, there was a significant difference in the increase in muscle activity of the external oblique and transverse abdominal muscles in the Pilates breathing group (p < 0.05). In the pre-post comparison of static and dynamic balance within the Pilates breathing group, there was a significant increase (p < 0.05) after exercise. The Pilates breathing group also showed a significant increase even in the between-group comparison (p < 0.05). Conclusion: This study confirmed that reformer footwork exercise accompanied by Pilates breathing has positive effects on muscle activity and static balance ability of trunk muscles in adult women. Therefore, reformer footwork exercise accompanied by Pilates breathing can be presented as an effective exercise method to increase trunk stability and balance ability through the simultaneous activity of the trunk muscles.
