The purpose of this study is to confirm the validity of respiratory retraining exercise using pressure biofeedback units among patients with stroke as an effective intervention for improving inspiratory function. 30 patients with stroke were recruited as subjects. Among them, 15 patients were randomly assigned to an experimental group performing lumbar stabilization exercise and respiratory retraining exercise, and other 15 patients were randomly assigned to a control group conducting only lumbar stabilization exercise. Exercise was implemented three times a week for six weeks. The experimental group performed stabilization exercise for half an hour and respiratory retraining exercise for 20 minutes. For tests, a preliminary test before training, a test three weeks after training, and a test six weeks after training were carried out. For results from this study, the interaction between three durations including a preliminary test (0 week), a test three weeks after training, and a test six weeks after training and groups was statistically significant in strength index and peak inspiratory flow (p<.05). A test for main effects according to the duration of experiment indicated a significant difference in comparing strength index, peak inspiratory flow and inspiratory volume in each group (p<.05). The above results showed that the joint implementation of respiratory retraining exercise and lumbar stabilization exercise had more positive effects in inspiratory function than performing ordinary lumbar stabilization exercise. 본 연구의 목적은 뇌졸중 환자를 대상으로 압력 생체되먹임 장치를 이용한 호흡재교육 운동이 들숨기능에 미치는 영향을 알아보고 중재 방법으로 타당한지 알아보고자 진행되었다. 연구대상자는 뇌졸중 환자 총 30명을 대상으로, 허리 안정화 운동 및 호흡재교육 운동한 실험군 15명과 허리 안정화 운동만을 시행한 대조군 15명을 무작위로 배정하였다. 훈련은 6주 동안 주 3회 실시하였으며, 실험군은 허리 안정화 운동 30분, 호흡재교육 운동 20분을 실시하였다. 검사는 훈련 전 사전검사, 훈련 3주 후 검사, 훈련 6주 후 검사를 시행하였으며, 각 그룹 내 중재 기간에 따른 비교와 그룹 간 비교를 통해 종속변수에 미치는 효과를 알아보고자 하였다. 본 연구의 결과는 사전검사(0주), 3주 후 검사, 6주 후 검사에 대한 세 기간과 집단의 상호작용은 들숨압력과 최대들숨유속에서 통계학적으로 유의한 차이가 있었다(p<.05). 각 군의 들숨압력, 최대들숨유속, 들숨량에서 실험 기간에 따른 주 효과 검정에서는 유의한 차이가 있었다(p<.05). 이러한 결과를 미루어 볼 때 호흡재교육 운동과 허리 안정화 운동의 병행이 일반적인 허리 안정화 운동만 수행하는 것보다 들숨에 긍정적인 효과를 보인 것으로 알 수 있었다.
Effects of Social Support and Self-Efficacy on the Quality of Life of Elderly People

Objective: This study investigated how social support and self-efficacy affect the quality of life of elderly people with chronic diseases. Design: The study consisted of descriptive survey research. Methods: A questionnaire covering social support, self-efficacy, and quality of life was distributed to 320 elderly people with chronic diseases. Pearson’s correlation analysis was performed to examine the correlation between the respondents’ social support (family support, friend support, medical support), self-efficacy (confidence, self-regulation efficacy, preference for task difficulty), and quality of life. Multiple regression analysis was also performed to identify the factors affecting the respondents’ quality of life. Results: “Friend support" and “quality of life” (r=-636, p<0.001), had a negative correlation, “confidence” and “quality of life” (r=0.827, p<0.001), “self-regulating efficacy” and “quality of life” (r=0.736, p<0.001), and “preference for task difficulty” and “quality of life” (r=0.295, p<0.001)—had positive correlations. Friend support (β=-0.164, p<0.001), confidence (β=0.592, p<0.001), and self-regulation efficacy (β=0.160, p<0.001) were found to affect quality of life. The independent variables showed the following degrees of influence, in order: confidence, friend support, and self-regulation efficacy. Their explanatory power was 73.3% (F=146.844, p<0.001). Conclusions: The quality of life of elderly people with chronic diseases can be improved by formulating health-promotion programs that foster a sense of community.
