폐 종양의 위치에 따라 사이버나이프 치료 시 치료기법의 선택에 대해 고려해봐야 합니다. 폐암 환자 28명을 대상으로 18개 지점에 대해 4차원 단층촬영영상을 분석하였고, 응용프로그램을 통해 위치오차값을 추출하였다. 평가 결과 상부와 내측에서만 평균 위치오차값보다 낮았다. 이러한 결과를 통해 폐첨부에 가깝거나 척추체부에 가까운 경우 척추추적기법을 적용하는 것이 효율적이며, 이외의 위치에서는 호흡동조기법이 효율적이다. 이에 본연구를 기반으로 하여 향후 폐종양의 폐내 종양의 위치뿐만 아니라 폐활량에 따른 확장범위 및 환자마다 차이가 발생하는 호흡주기에 따라 사이버나이프 치료기법을 선택할 경우 효율적인 치료기법을 선택할 수 있도록 연구하고자 한다.

Purpose : The purpose of this study was to investigate the effects of abdominal functional electrical stimulation on peak cough flow and forced vital capacity in patients with cervical spinal cord injury. Methods : The study examined 20 patients with cervical spinal cord injury. The subjects were randomly divided into two groups. All subjects performed conservative physical therapy for 30 minutes. The experimental group also underwent abdominal functional electrical stimulation for at least 20 minutes per day. Abdominal functional electrical stimulation was applied to the rectus abdominis muscle twice each day, three times a week, for four weeks. In all subjects, the peak cough flow was measured using a peak flow meter and forced vital capacity was assessed using a spirometer. Results : The experimental group showed a significant increase in peak cough flow and forced vital capacity in pre-post measurements (p<.05), while the control group showed a significant increase only in peak cough flow. Conclusion : These findings suggest that conservative physical therapy in combination with the abdominal functional electrical stimulation can improve peak cough flow and forced vital capacity in patients with cervical spinal cord injury.

요부안정화 운동은 척추 주변 근육과 복부 근육을 강화시켜 최근 임상에서 많이 사용하는 운동 방법이지만 호흡기능에 어떠한 영향을 미치는지에 대한 연구는 부족한 실정이다. 이에 본 연구에서는 대표적인 요부안정화 운동인 복부 브레이싱 운동이 정상 성인의 호흡기능에 효과적인지를 알아보고자 실시하였다. 20대 성인 40명을 대상으로 각각 복부 브레이싱 운동을 25분간 실시하는 실험군과 일상생활을 25분간 하는 대조군으로 무작위 배치하였다. 호흡기능의 변화량을 비교하기 위하여 노력성 폐활량, 1초간 노력성 호기량과 최대호기유속을 통해 폐기능 검사를 하였고, 호흡압력의 변화량을 알아보기 위해 최대 호기압력과 최대 흡기압력을 측정하였다. 본 연구의 실험 결과 실험군에서 폐기능과 호흡압력 모두 유의하게 증가되었고(p<.05), 그룹 간 비교에서는 최대 흡기압력을 제외한 나머지 수치에서 유의한 차이가 있었다(p<.05). 이러한 결과는 복부 브레이싱 운동이 호흡기능을 향상시키기 위한 효과적인 운동으로 제시될 수 있다고 사료된다.

Purpose : The purpose of this study was to investigate the effect on lung capacity of healthy men and women in their twenties by performing an intervention using the chest extension exercise and the bridge exercise, which are respiratory muscle strengthening exercises. Methods : Thirty adult men and women in their 20s participated in this study. All subjects participated in the study after hearing the explanation of the purpose and method of the study, filling out a consent form. All subjects were randomly assigned to the chest extension exercise (CEE) group and the bridge exercise (BE) group of fifteen each. Each exercise was performed twice a week for 4 weeks. Lung capacity was measured by forced vital capacity (FVC) and forced expiratory volume in one second (FEV₁) using spirometry. Lung capacity was measured before and after exercise. The measured data were compared through the dependent t-test and the independent t-test. The statistical significance level was set at .05. Results : After the intervention, the CEE group showed a significant increase in FVC and FEV₁ compared to before the intervention (p<.05). After the intervention, the BE group also had a significant increase in FVC and FEV₁ compared to before the intervention (p<.05). However, there was no difference in FVC and FEV₁ between groups before and after the intervention (p>.05). Conclusion : There was no difference between groups in lung capacity after exercise. However, both the chest extension exercise and the bridge exercise increased FVC and FEV1, which was thought to be because both exercise methods were effective in increasing lung capacity. Therefore, both chest extension exercises and bridge exercises can be effectively applied as a way to increase lung capacity.

Background: This study was to determine whether the diaphragmatic breathing exercise using a DiP Belt(Diaphragmatic Pressure Belt) is effective in increasing the diaphragmatic motion and forced vital capacity. Design: Pretest-Posttest design. Methods: A total of 44 subjects(15 male, 29 female) participated in this study. All subjects were measured the diaphragmatic motion with a sonography and the Forced Vital Capacity(FVC) was measured with a digital spirometer. After 4 weeks, the subjects were intervened the diaphragmatic breathing exercise using a DiP belt and were remeasured for diaphragm motion and FVC. Results: After exercise intervention, quiet breathing significantly increased with the change in diaphragmatic motion and showed a moderate effect size (p<.01, Cohen's d = -0.53). In addition, it was significantly increased in deep breathing and showed a high effect size (p<.001, Cohen's d = -1.32). The mean diaphragmatic contraction pressure increased, but there was no significant difference and the peak diaphragmatic contraction pressure increased significantly (p<.05). Both diaphragmatic contraction pressure showed small effect sizes (respectively Cohen's d = -0.28, -0.33). In spirometry, FVC, Forced Expiratory Volume in 1 second (FEV₁), and FEV₁/FVC% all increased, but there was no significant difference. Only peak expiratory flow increased significantly and showed a small effect size (p<.05, Cohen's d = -0.41). Conclusion: The DiP belt diaphragmatic breathing exercise that the principle of visual feedback can correct diaphragm breathing in a short time, so it is a useful breathing exercise device that can help the diaphragm breathing exercise in the right way in clinical practice.

Purpose: This study aimed to examine the immediate effects of different breathing training techniques on diaphragm excursion and vital capacity in healthy adults. Specifically, the study focused on comparing respiratory exercise without PNF, bilateral pattern respiratory exercise, and bilateral pattern with spiral pattern respiratory exercise. Methods: Twenty-seven healthy adults in their 20s participated in the study. Diaphragm excursion and vital capacity were evaluated under three different conditions. A one-way repeated ANOVA was used to analyze the differences in diaphragm excursion and vital capacity among the interventions. Results: Statistically significant differences were observed in diaphragm excursion among the interventions, comparing respiratory exercise without PNF, bilateral pattern respiratory exercise, and bilateral pattern with spiral pattern respiratory exercise. Similarly, statistically significant differences were found in vital capacity among the interventions without PNF respiratory exercise, bilateral pattern respiratory exercise, and bilateral pattern with spiral pattern respiratory exercise. Conclusion: The study demonstrated that incorporating the spiral technique in respiratory exercise led to increased diaphragm excursion and lung capacity compared to other interventions. These findings suggest that PNF respiratory exercise combined with the spiral pattern may have clinical implications for the treatment of respiratory diseases. Further research is warranted to explore the long-term effects and clinical application of these approaches.

Purpose : This study aimed to compare lung capacity measures (forced vital capacity; FVC, forced expiratory volume at 1 second; FEV1, and FEV1/FVC) and the activities of rectus femoris (RF) and gastrocnemius (GCM) muscles between young adults prescribed aerobic exercise combined with lower limb strength exercise (complex exercise) and those prescribed only aerobic exercise. Methods : We randomly divided 22 young adults into 2 groups: the complex exercise group that combined the leg strengthening and aerobic exercises (n = 11) and the aerobic-exercise-only group (n=11). Before the intervention, the FVC, FEV1, and FEV1/FVC values and the activities of RF and GCM muscles were measured. Measurements were in triplicates, and the average of the 3 measurements was used. The complex exercise group performed the treadmill exercise followed by squats and lunges, and the group performed only the treadmill exercise. Both groups were allocated the same time. Both groups performed the assigned exercise thrice a week for 3 weeks. After the intervention, the FVC, FEV1, and FEV1/FVC values and the activities of RF and GCM muscles were measured again. Results : The FVC and FEV1 values increased significantly in both groups after the intervention (p<.05). RF activity increased significantly after the intervention in the complex exercise group (p<.05), and the magnitude of change in RF activity after the intervention was significantly higher in the complex exercise group than in the aerobic-exercise-only group (p<.05). GCM activity also significantly increased after the intervention in both groups (p<.05). Conclusion : On the basis of our results, we recommend combining leg strengthening and aerobic exercise to improve leg muscle activity along with lung function.
