Purpose: To investigate breathing-related changes in the balance ability of healthy adults. Methods: The participants were 36 healthy adults in their 20s and 30s. All participants were trained in three breathing (neutral, thoracic, and abdominal) methods one week before measurements. We used AccuSway to measure each participant's balance ability, using each breathing technique, in two postures (bipedal and unipedal). Results: During the bipedal balance task, abdominal breathing produced significant increases in path length and sway velocity. Abdominal breathing resulted in significant changes in sample entropy at the anteroposterior location compared with neutral breathing (p<.05). In the normalized anteroposterior location, there were significant changes in backward movement during thoracic and abdominal breathing compared with those during neutral breathing (p<.05). During the unipedal balance task, path length and sway velocity increased significantly during voluntary breathing compared with those during neutral breathing (p<.05). There was a significant change in backward movement when abdominal breathing-compared with neutral breathing-was used in the normalized anteroposterior location (p<.05). In the normalized left-right location, there was a significant shift to the right during thoracic breathing compared with that during neutral breathing (p<.05). Conclusion: Compared with neutral breathing, altered voluntary breathing patterns affect balance in healthy adults. Our results indicated that that static balance was more affected by abdominal breathing than by neutral breathing. Future studies should examine variables such as the breathing volume, rhythm, and method.

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.

PURPOSE: The aim of this study was to examine the effects of abdominal breathing and thoracic expansion exercises on craniovertebral and cranial rotation angles in patients with rotator cuff injury. METHODS: This study enrolled 19 patients with rotator cuff injury, and ten and nine of the patients were randomly placed in abdominal breathing and thoracic expansion exercise groups, respectively. After pain treatment in each group, breathing exercise was conducted thrice a week for four weeks. The patients were recorded by using a digital camera and Image J (version 1.46, National Institutes of Health, USA), an angle measurement program, was used to analyze changes in the craniovertebral angle, cranial rotation angle, and sagittal shoulder posture. RESULTS: Statistically significant differences in the craniovertebral angle were found in both the abdominal breathing and thoracic expansion exercise groups (p<.05). A significant difference in cranial rotation angle was found in the thoracic expansion exercise group only (p<.05). No statistically significant differences in sagittal shoulder posture were found in both groups (p>.05). CONCLUSION: Although abdominal breathing and thoracic expansion exercises did not effectively change sagittal shoulder posture, the exercises were effective in improving craniovertebral and cranial rotation angles. Therefore, abdominal breathing and thoracic expansion exercises are suggested as effective exercise programs for forward head posture.

Purpose : To investigate the relationship between breathing pattern disorder and joint position error (JPE) in patients with chronic low back pain (CLBP). Methods : Thirty nine patients with CLBP participated. End-tidal $CO_2$ and respiration rate (RR) were measured using a capnography. Breathing-hold time (BHT) and Nijmegen Questionnaire (NQ) were investigated. Thoracic excursion was measured with a cloth tape measurement technique. Joint position error were measured using a small laser point mounted on a lightweight headband. they were asked to relocate the head, after the neck movement on the horizontal plane. Pearson 's test was used for correlation analysis between respiratory variables and JPE in patients with CLBP. Independent t-test was used to verify the difference between thoracic and diaphragm breathing pattern in patients with CLBP. The significance level was set at 0.05. Results : There was a significant correlation between JPE (LR) and JPE (RR, EX) (r=.639, r=.813) (p<.001) and a low negative correlation with end-tidal $CO_2$ (r=-.357) (p<.05). There was a significant correlation between RR and JPE (EX) (r=.750) (p<.001). There was a low correlation between JPE (EX) and NQ (r=.333) (p<.05). There was a somewhat high negative correlation between NQ and thoracic excursion (r=-.528) (p<.001). There was a somewhat high negative correlation between thoracic excursion and JPE (LR, RR, EX) (r=-.470, r=-.484, r=-.602) (p<.001). There were no significant differences in the RR, BHT, NQ, and thoracic excursion between the thoracic and diaphragmatic breathing (p>.05). There was a significant difference in the JPE (EX), end - tidal $CO_2$, and VAS values between the thoracic and diaphragm breathing (p<.05). Conclusion : There was a correlation between JPE (EX) and NQ in patients with CLBP, and correlation between thoracic excursion and JPE (LR, RR, EX) and NQ. There was a significant difference in the JPE (EX), end-tidal $CO_2$ level, and VAS value in the comparison of thoracic breathing and diaphragm breathing. The results showed that breathing patterns and JPE were related to each other.

Background: To evaluate the effect of thoracic mobility exercise and deep breathing exercise applied to stroke patients on pulmonary function. Methods: The subjects were divided into two group. Twenty-five patients with stroke were randomly assigned to DB (deep breathing exercise) group (n=13) and TM (combination of deep breathing exercise and thoracic mobility exercise) group (n=12). During four weeks, DB group were carried out deep breathing exercises for 5~10 minutes twice a day and TM Group were carried out deep breathing exercises for 5~10 minutes and thoracic mobility exercise for 20~30 minutes twice a day. All tests were completed before and after experiment. The pulmonary functions were measured by PowerBreathe K5 (Hab International Ltd, England) and tape measure respectively. For each case, the experimental data were obtained in 4 items; average of inspiratory load, inspiratory flow speed, inspiratory flow volume and chest expansion. Results: The results of this study were as follows: 1. In DB group, the statistically significants were shown on average of inspiratory flow speed, inspiratory flow volume and chest expansion (p<.05). 2. In TM group, the statistically significants were shown on all items (p<.05). 3. There was a statistically significant difference on all items between DB group and TM group (p<.05). Conclusions: The above results revealed that DB and TM group can be used to improve pulmonary function in stroke patients. In comparison of DB and TM group, TM group was more improved. In conclude, thoracic mobility exercise helped improving function of vital capacity and chest expansion in stroke patients.

The purpose of this study was to examine the effects of combined respiratory physical therapy on respiratory function, spinal curve and spinal mobility for community-dwelling elderlies with restrictive lung diseases. In total, 10 patients participated in an 8-week intervention program of thoracic cage mobilization and breathing exercise in combination. The results of the study are as follows: for respiratory function, the forced expiratory volume in 1 second (FEV1), forced vital capacity(FVC), and FEV1/FVC were significantly improved to $.30{\pm}0.31{\ell}$, $.46{\pm}.42{\ell}$, and $18.10{\pm}11.39%$, respectively (p<.05). For spinal curve, the thoracic curve and the lumbar curve were improved significantly to $-2.20{\pm}1.40^{\circ}$ and $-1.20{\pm}1.14^{\circ}$, respectively (p<.01). For spinal mobility, the thoracic flexion ($3.40{\pm}2.99^{\circ}$), thoracic extension ($3.50{\pm}1.43^{\circ}$), lumbar flexion ($4.50{\pm}4.74^{\circ}$), and lumbar extension($-1.50{\pm}1.84^{\circ}$) were all significantly improved (p<.05). These findings indicate that thoracic cage mobilization and breathing exercise in combination improve the respiratory function, spinal alignment, and spinal mobility in elderly people with restrictive lung diseases.

Purpose : The purpose of this study was to investigate the effects of stabilization exercise and breathing exercise on the flexion relaxation phenomenon (FRP) and respiratory parameters in patients with chronic low back pain. Methods : We randomly allocated 30 chronic low back pain patients (CLBP) to a stabilization exercise (SE) group (n=15) and a breathing exercise (BE) group (n=15). FRP was measured using surface electromyography (SEMG). Thoracic excursion was measured with a cloth tape measurement technique. The SE group participated in a stabilization exercise program and the BE group participated in a breathing exercise program three times a week for 12 weeks. The data was analyzed using paired t-tests for comparisons of flexion relaxation ratio (FRR) and respiratory variables. Independent t-tests were used for comparison of inter-group FRR and respiratory variables. The significance level was set at .05. Results : FRP variables-ES FRR (Flex/MVF), ES FRR (Ext/MVF), MF FRR (Flex/MVF), and MF FRR (Ext/MVF) values-increased significantly after exercise in both the SE and BE groups (p<.05). The thoracic excursion measurements after exercise increased significantly in both groups (p<.001). VAS values decreased significantly in both groups (p<.001). There were no significant differences between the two groups in FRP variables-ES FRR (Flex/MVF), ES FRR (Ext/MVF), MF FRR (Flex/MVF), and MF FRR (Ext/MVF)-or VAS values after exercise (p>.05). For thoracic excursion after exercise, the BE group was significantly higher than the SE group (p<.001). Conclusion : We found that FRP and respiratory variables increased significantly after SE and BE for 12 weeks in CLBP. Thoracic excursion-a respiratory variable-suggests that treatment was more effective in the BE group than the SE group.

연구의 목적은 의사호흡정지(QBH) 바이오 피드백이 의료영상획득 시간의 큰변화 없이 잔류 호흡 운동을 조절함으로써 호흡 운동에 의한 영상 오류를 줄이고, 게이트 3차 흉부 자기 공명 영상을 향상시킬 수 있다는 가설을 실험하는 것이다. 가설을 확인하기 위해 건강한 다섯 사람을 대상으로 3T 지멘스 엠알아이의 호흡 탐색기가 포함된 T2 가중 스페이스 엠알 펄스 시퀀스를 이용해 두번의 게이트 자기공명 영상 연구를 시행 하였다: 자유 호흡 상태와 의사호흡정지 바이오 피드백 호흡상태, 의사호흡정지 바이오 피드백 시스템은 알피엠(RPM) 시스템(실시간 위치 관리시스템, 베리안)을 사용하여, 복부의 외부 위치를 측정하고, 음향과 시각적으로 각각의 호흡주기의 90% 위치에서 2초 숨을 정지하도록 안내하는 방법을 사용했다. 평가방법은 의사호흡정지 바이오 피드백 시스템을 이용시 간 상부의 호흡정지모습의 재현성이 게이팅 영역 내에서 향상되는지를 지원자의 실험을 통해 평가하였다. 자유호흡상태와 의사호흡정지 바이오 피드백상태에서 3차 흉부자기공명영상내에 호흡 운동에 의한 영상 오류와 게이팅영역 내에서의 잔류 호흡 운동 조절여부도 함께 평가했다. 또한, 복부 변위의 RMSE도 (제곱근오차) 조사되었다. 의사호흡정지 바이오 피드백방법을 사용함으로 자유호흡의 경우보다 게이트 3차 흉부 엠알 영상에서 폐와 간에서 호흡운동에 의한 영상오류의 감소 결과를 획득했다(영상획득시간: ~6분). 이는 의사호흡정지 바이오 피드백사용시, 게이팅 영역에서 복부 운동 감소와 횡경막의 잔류 움직임 감소가 일치함을 의미한다. 따라서, 알피엠을 통해 얻은 복부 변위의 전체 자료에서평균 RMSE는 (제곱근오차) 자유 호흡의 2.0 mm에 비해 7 mm (67% 감소, p값=0.02)로 감소하였으며, 게이팅영역만을 고려했을때는 자유 호흡의 1.7 mm가 의사호흡정지 바이오 피드백 호흡을 사용함으로써 0.7 mm (58 % 감소, p값=0.14) 로 개선되었다. 선형 피팅을 사용하여 얻은 평균 기준 이동값은 의사호흡정지 바이오 피드백 을 사용하면 자유 호흡 5.5 mm/분보다 0.6 mm/분(89% 감소, p값=0.017)으로 감소되었다. 이 연구는 의사호흡정지 바이오 피드백을 이용해 게이트 3차 흉부 자기 공명 영상 중에 간 상부의 호흡정지 재현성이 향상되는 것을 보여 주었다. 이 시스템은 내부 해부학의 운동을 조절함으로써 게이트 의료 영상과 방사선 치료에 임상적으로 적용 할 수 있다.
