PURPOSE: The purpose of this study was to compare the effect of depending on the location of applying chest expansion resistance exercise on the respiratory muscle strength stroke patients, and to suggest more effective interventions to improve respiratory function in stroke patients in clinical practice. METHODS: A total of 30 subjects were selected and divided into two groups, and chest cage extension resistance exercise was applied to the sternum and rib cage, respectively, and performed for 4 weeks, 3 times a week, for 20 minutes. In order to compare the general characteristics of the study subjects and the homogeneity of the group, the pre-experimental values were analyzed using the independent sample t-test. Paired-sample t-test was used for pre-post value comparison of maximum inspiratory pressure and maximum expiratory pressure in each group. Statistical significance was set to .05. RESULTS: Both the sternum application group and the rib cage application group showed a significant difference in the maximum inspiratory pressure according to the intervention. Also, there was a statistically significant difference in the maximum expiratory pressure in the sternum application group. CONCLUSION: As breathing exercise is important for stroke patients, based on the results of this study, if therapists perform sternal extension resistance exercise or rib extension resistance exercise according to the patient's condition and environment, it can help the breathing function of stroke patients.

Objective : Respiratory muscle weakness and decreased chest mobility has been suggested to result from the deconditioning that accompanied activity level in chronic elderly stokes. The benefits of respiratory exercise programmes on exercise capacity and muscle strength in hemiplegia. This study aimed to determine the effects of selective inspiratory and expiratory muscles training and chest mobility exercise on patients with strokes to establish if an improved exercise capacity can be obtained in patients that are not limited in their daily activities. Methods & Intervention : Twelve patients were assigned to the intensive respiratory exercise group participated in a measures design that evaluated the subjects with pre-treatment and post-treatment. Thirteen subjects who were assigned to a control group received training with breathing exercise and resistance exercise of skeletal muscles. The subjects performed spirometry then undertook a 6-week programme of respiratory muscle and chest mobility training. Training for the two groups was carried out 2 times a week for 6 weeks. Measurements and Results : Spirometry(Forced Vital Capacity: FVC and Closed Circuit Spiromety: CCS) and thoracic mobility were measured before and after the 6 weeks. The experimental group improved significantly compared to control group in FVC, $FEV_1$, MVV, IRV and ERV, and upper chest wall expansion(p<0.05). No significant improvement was seen in thoracic mobility or lung function in control group(p>0.05). Conclusion : The major findings in this study were that a intensive 6week exercise programme of resistive breathing and chest mobility in patients with hemiplegia led to an increase in lung capacity. The resistive breathing exercise programme used here resulted in a significant increase in the chest excursion during breathing.

Purpose: The purpose of this study was to determine the effects of chest resistance exercise on Forced Expiratory Volume per second and on fatigue in patients with chronic obstructive pulmonary disease (COPD). Methods: In all, 62 male patients with COPD were included in this study. The experimental group included 32 patients who were treated with chest resistance exercise using the PNF technique with medication. The control group included 30 patients who were treated only with medication. Subjects were stratified into the 2 groups by randomized clinical sampling. Before the start of the experiment, forced expiratory volume at the first second (FEV1) and lactic acid were tested in both experimental and control groups. The experimental group did chest resistance exercise for 6 weeks, 4 times per week, 30 min per day, and the effects of this exercise in patients with COPD was determined by comparing the results of FEV1 and lactic acid tests before and after the experiment between and within the experimental and control groups. Results: There was a statistically significant within group difference for FEV1 MEAS and FEV1 %PRED. There was statistically significant control group of FEV1 MEAS and FEV1 %PRED There was a statistically significant difference in the experimental group for fatigue, comparing scores before and after the test. There was a statistically significant control group of fatigue, in comparison of between the groups of FEV1 MEAS, FEV1 %PRED, fatigue(p<0.01)(p<0.05). Conclusion: More research on COPD will be necessary for improving pulmonary function and reducing fatigue. Further studies on COPD will be required for improving pulmonary function and reducing of fatigue.

PURPOSE: This study compared the effects of chest expansion resistance exercise (CERE) and breathing retraining (BRT) on stroke patients' chest expansion and maximal inspiratory pressure(MIP), thereby intending to present an effective intervention method for enhancing their respiratory functions. METHODS: The subjects were 30 stroke patients and randomly and equally assigned to a CERE group (10), a BRT group (10), and a control group (10). The intervention was applied to each group five times per week, 30 minutes per each time, for six weeks. A tapeline was used to measure upper and lower chest expansion and MIP prior to and after the intervention and the results were compared. RESULTS: After the intervention, the upper and lower chest expansion was considerable in the CERE group (p<.01), significant in the BRT group (p<.05) but was not significant in the control group (p>.05). According to the post-hoc test result, the upper and lower chest of the CERE group and the BRT group significantly expanded compared to that of the control group (p<.05) and the upper and lower chest of the CERE group statistically significantly expanded relative to that of the BRT group (p<.05). According to the MIP evaluation result, the CERE group saw considerable improvement (p<.01) and the BRT group underwent significant changes (p<.05), but there were no significant changes in the control group (p>.05). The post-hoc test result was that the CERE group and the BRT group saw significant improvement compared to the control group (p<.05) and the CERE group experienced statistically significant enhancement relative to the BRT group (p<.05). CONCLUSION: As an intervention for respiratory function improvement, CERE is considered effective for strengthening respiratory muscles and promoting chest expansion through manual resistance by a therapist.

Objective: The purpose of this study was to compare the activities of the abdominal muscles according to trunk stabilization exercises using Swiss ball in normal individuals. Design: Cross-sectional study. Methods: Ten healthy university students participated in this study. The subjects were required to complete the following three exercise positions: Exercise position 1, sitting on a Swiss ball and lifting the legs; Exercise position 2, pushing to a plank position from an ending position; and Exercise position 3, push-up posture with the legs on a Swiss ball. Changes in the trunk muscle activities were estimated using Biometric electromyography (EMG). Activities of the dominant side internal oblique muscle (IOM) and external oblique muscle (EOM) were estimated in all participants. The maximal voluntary isometric contraction (MVIC %) was measured to standardize the EMG signals for the IOM and EOM during maximum resistance when sitting up with each shoulder pointing towards the contralateral pelvis with knees bent and both arms crossed on the chest for 5 seconds. Results: There was a significant difference in the activity of the internal and external oblique muscles between Exercises 1 and 2 and Exercises 1 and 3 (p<0.05). Furthermore, the IOM/EOM activity ratio was the greatest during Exercise 3 and the smallest during Exercise 1. IOM and EOM activities were the greatest during Exercise 2 with greater EOM activity. Conclusions: In future studies, it will be necessary to investigate muscle activities by supplementing the above-mentioned limitations during the stabilization exercise. The results of this study may be used as a basis for controlling the intensity and frequency of exercise while prescribing trunk stabilization exercises.

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.

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.
