목 적 : 본 연구는 이미 상용화가 시작된 호흡 동조 체적 세기조절 회전 방사선 치료(Gated RapidArc) 이전의 자동화가 되지 않는 장비들에서 호흡 동조 방사선 치료(Gated radiation therapy)와 체적 세기조절 회전 방사선 치료(VMAT)를 동시에 시행할 수 있게 Gated RapidArc의 정확성을 분석하여 유용성을 평가하고, 진폭모드(Amplitude mode)를 이용하여 Gated RapidArc가 자동으로 되지 않는 장비에 환자를 적용하여 보고자 하였다. 대상 및 방법 : 방사선량 분포의 분석은 물 등가물질 고체 팬톰과 GafChromic 필름(EBT2 QD+, USA)을 이용하였으며, Film QA (ver. 2.2, USA) 필름 분석 프로그램을 이용하여 Gamma 인자(3%, 3 mm)를 분석하였다. 또한, 삼차원 선량 분포의 정확도를 확인하기 위해서 Matrixx(IBA Dosimery, Germany) 선량 측정 장비와 Compass(IBA Dosimetry, Germany) 선량 분석 프로그램을 이용하였다. 고체 팬톰을 이용한 호흡 동조 주기 신호는 4D 팬톰(Dynamic Thorax Phantom, CIRS, USA)과 Varian RPM(Real-Time Position Monitor) 호흡 동조 시스템을 이용하여 만들었으며, 자유호흡(free breathing)과 호흡정지(breath holding) 시에 따른 방사선량 분포를 각각에 대하여 분석 평가하였다. 환자에게 적용하기 위하여 2013년 2월부터 2013년 8월까지 간암환자 4명을 대상으로 4DCT의 영상을 얻기 위하여 충분한 호흡주기 연습후에 환자의 호흡주기에 맞게 위상모드(Phase mode)를 이용하여 환자가 고글의 호흡주기 패턴을 눈으로 보고 정확하게 따라할 수 있도록 하면서 4DCT의 영상을 획득하였다. Gated RapidArc 치료를 위하여 진폭모드(Amplitude mode)의 호흡주기를 만들어 3회 호흡을 시행한 후 40%~60%의 구간에서 5~6초 호흡을 참을 수 있도록 연습을 하고, 치료 시 40%~60%의 구간에서 환자가 숨을 참을 때 Beam On 버튼을 눌러주는 방식의 반자동으로 치료를 시행하였다. 결 과 : 비 호흡 및 호흡 동조 체적 세기조절 회전 방사선 치료기법 간의 절대선량은 전산화 치료 계획을 이용한 계산값과 1% 이내의 차이를 보였으며, 치료 기법 간의 차이 또한 1% 이내의 차이를 보였다. Gamma 인자(3%, 3 mm)는 99% 이상의 일치함을 보였으며, 각 장기별 선량 차이는 대체로 95% 이상의 일치함을 보였다. 또한 호흡 동조 체적 세기조절 회전 방사선 치료를 위하여 만든 진폭모드(Amplitude mode)의 호흡주기와 실제 환자의 호흡주기가 잘 일치하는 것을 볼 수 있었다. 결 론 : 비 호흡 동조와 호흡 동조 시 체적 세기조절 회전 방사선 치료간의 절대 선량 및 방사선량의 분포가 매우 잘 일치함을 보였다. 이는 호흡 동조 체적 세기조절 회전 방사선 치료 기법을 이용하여 호흡에 따라 움직이는 흉부나 복부의 종양 치료에 적용이 가능한 것으로 사료된다. 또한 실제 치료환자를 대상으로 고글을 통하여 진폭모드(Amplitude mode)의 호흡주기를 만들어 Gated RapidArc가 자동으로 되지 않는 장비에 치료를 적용한 결과, 5~6초정도 정지된 호흡에서 호흡 동조 체적 세기조절 회전 방사선 치료가 원활히 이루어짐을 알 수 있었다.

Purpose: The study aims to determine the effect of a breathing exercise on shoulder pain, range of motion (ROM), and forward head posture in patients with rotator cuff repair. Methods: In total, 25 patients with rotator cuff repair were included in this study. The experimental group (n = 13) underwent a breathing exercise, while the control group (n = 12) received traditional physical therapy. The visual analogue scales (VASs) for pain, flexion and abduction ROM, and the craniovertebral angle (CVA) of both groups were recorded at both pre- and post-intervention. Paired t-tests were used to determine significant changes in the post-intervention compared with the pre-intervention period, and independent t-tests were used to analyze differences in dependent variables between the two groups. Results: After the two-week intervention, the experimental group experienced a significantly decreased VAS (p < 0.05) and significantly increased ROM and CVA (p < 0.05), while the control group experienced a significantly decreased VAS (p < 0.05). Further, the experimental group that underwent the breathing exercise showed greater improvements in flexion and abduction ROM and in the CVA than the control group (p < 0.05). Conclusion: The results suggested that a breathing exercise can reduce shoulder pain and enhance ROM and posture in patients with rotator cuff repair.

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: The aim of this study is to suggest an intervention method for clinical use in the future by analyzing the effect of breathing exercise on activity of sternocleidomastoid muscle and scalenus anterior muscle, which are respiratory synergist muscles, and pulmonary functions in patients with forward head posture. Methods: Prior to the experiment, 12 patients (experimental group) performed feedback exhalation exercise along with conventional deep neck exercise, and 11 subjects (control group) performed feedback deep neck exercise along with conventional deep neck exercise. The intervention programs were performed for 40 minutes once a day (three times a week for four weeks). Results: Before intervention, %RMS was measured for surface electromyography (sEMG), and FVC, FEV1, and FEV1/FVC were measured using a spirometer. After four weeks, these items were re-measured under the same condition and analyzed. In within-group comparison of the experimental group, activity of sternocleidomastoid muscle and scalenus anterior muscle showed a significant decrease (p<0.05)(p<0.001), and forced vital capacity (FVC) showed a significant increase (p<0.05). In within-group comparison of the control group, activity of sternocleidomastoid muscle and scalenus anterior muscle showed a significant decrease (p<0.05), and in between-group comparison, there were significant differences in activity of sternocleidomastoid muscle and FVC (p<0.05). Conclusion: Long-term forward head posture restrains exercise performance of the neck and leads to exercise avoidance of the neck during daily activities, thus restraint factors might be created even while breathing. To cut off this link, a constant effort is required and diversified research on the correlation between neck functions and breathing should be conducted.

Purpose: This study attempts to determine the effects of applying three kinds of breathing exercises for four weeks on the neck muscle activation of subjects with a forward head posture. Methods: A total of 30 adults aged in their twenties (15 men and 15 women) with a forward head posture who voluntarily agreed to participate after listening to the purpose and procedure of this research were chosen as the subjects of this study. The subjects were randomly divided into either the diaphragmatic breathing exercise (DBE) group, the abdominal drawing-in maneuver (ADIM) group, or the abdominal expansion method (AEM) group according to the breathing intervention scheme. Each group included ten subjects. The muscle activity of the sternocleidomastoid, scalenus anterior, and splenius capitis was measured in all the groups prior to the intervention, two weeks after the intervention, and four weeks after the intervention. All the interventions were implemented for 30 minutes a day, three times a week, for a total of four weeks. Results: No significant between-group difference was observed in terms of the change in neck muscle activity according to the four-week intervention scheme. Further, there was no interaction between the intervention period and the intervention scheme in relation to the change in neck muscle activity. Conclusion: The results of this study suggest that abdominal expansion exercise is as effective as other breathing exercise methods for subjects with a forward head posture. We therefore expect that abdominal expansion exercise can be used as a scheme for the prevention of symptoms as well as therapy for patients with a forward head posture.

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 aim of this study was to determine the effectiveness of breathing exercises and lumbar segmental exercises on the segmental stability of patients with chronic back pain. Methods: Fifty-nine patients, who suffered from chronic low back pain, were enrolled in this examination. They were divided randomly into three groups: experiment group 1 underwent breathing and segmental stabilization exercises (n=20), experiment group 2 experienced segmental stabilization exercises (n=20), and the control group was given the modality treatment (n=19). The measurements were assessed through an Oswestry disability questionnaire (ODQ), as well as a lumbar segmental instability test (LSIT). Results: The ODQ results for experimental groups 1 and 2 were similar (p<0.05), both before and after six weeks of exercise, but different among the three groups (p>0.05). The differences in segmental instability of each of the three groups were similar (p<0.05), and also similar among the three groups (p<0.05). Conclusion: These findings suggest that lumbar segmental stabilization exercises are efficient in increasing the segmental stability and alleviating pain in patients with chronic back pain. Additional studies on this subject will be needed to improve the clinical applications in the future.

Purpose : The purpose of this study is to compare the effects on abdominal muscle thickness and breathing by applying trunk strength exercise and deep stabilization exercise along with breathing exercise, which is the main respiratory muscle during breathing, to present an efficient exercise method with diaphragm breathing. Methods : This study was performed on normal 6 females and 14 males subjects. They were divided into 2 groups which trunk strength exercise and deep stabilization exercise group. The trunk strength exercise group (TSE) attended prone press-up, crunch and pelvic tiling. The deep stabilization exercise group (DSE) attended abdominal drawing, horizontal side-support and bridging exercise. Breathing exercise was performed for each set break time for 1 minute. Results : First, in the comparison of the change in the thickness of the abdominal muscle between the trunk strength training group and the deep stabilization group before and after exercise, there was a statistically significant difference in the comparison of transverse abdominis (TrA), rectus femoris (RF), external oblique (EO), internal oblique (IO) (p<.05). However, there was no significant difference in any comparison between groups (p>.05). Second, in the comparison of changes in respiratory function between the trunk strength exercise group and the deep stabilization exercise group before and after exercise, there were statistically significant differences in the exerted forced vital capacity (FVC), forced expiratory volume at one second (FEV₁), peak expiratory flow (PEF) in the comparison before and after the experiment (p<.05). However, there was no significant difference in any comparison between groups (p>.05). Conclusion : As a result of this study, it can be said that both trunk strength exercises and deep stabilization exercises along with diaphragm breathing are exercises that strengthen deep and superficial muscles, and have a positive effect on breathing function as well as muscle strength. However, it is not known which exercise was more effective, and because it was combined with breathing exercise, the interference effect appeared.
