This study was conducted to identify the relations between the factors influencing syndrome and physical disability of fibromyalgia patients. The subjects of this study were 125 outpatients selected at H. Rheumatism clinic from February to July in 1997, The Collected data were analyzed by Frequency, Pearson correlation using SPSS Windows and Path analysis using LISREL 7.16. The results were as follows. 1. General characteristics of subjects About 2/3 of subjects were over 40years of age and most of them were graduated from high school. The Christian were over a half (54.0%) of subjects. 2. Correlation between Family support, knowledge, Self-efficacy, Syndrome and physical disability. As knowledge was positively related to self-efficacy(r=.306), the family support was positively related to self-efficacy(r=.217), and family support was negatively to syndrome. Self-efficacy showed negative relation with syndrome and Physical disability. Syndrome as physical disability represent positive relation. Therefore all hypotheses were supported. 3. Causal relations between research variables. Family support influenced on syndrome, as syndrome on physical activity, as well as knowledge on self-efficacy & physical disability. The model also showed a good fit to the data[$X^2$=1.21 df=1(p=.546), GFI=.996, AGFI=.971, RMSR=.023]. 4. Correlation between symptoms of Fibromyalyia. Having analyzed the relations between tender point, pain, stiffness, functional disturbance, sleep disturbance, depression, fatigue, anxiety, the results were as follows ; All relations show statistically positive correlation, which means close relationship between symptoms, except between pain and depression, pain and anxiety. As a result, symptoms of Fibromyalgia had close relation. Therefore, these were common, rather than individual symptoms. This syndrome influenced on physical disability, and self-efficacy on the both, as knowledge on self-efficacy. In conclusion, to improve syndrome relief and physical disability of fibromyalgia, nursing interventions such as education, self-efficacy increasing stratagy, and family counseling are needed.

Purpose: The purpose of this study was to identify the levels of physical activity and its relationships with depression, health-related quality of life (QoL), sleep disturbance, and physiological indicators in hemodialysis patients. Methods: The participants in this study were 139 patients undergoing hemodialysis in the hospitals in Busan and Yangsan-si. Data were collected using hematologic tests and questionnaires that contained items about individual characteristics, International Physical Activity Questionnaires (IPAQ), Center For Epidemiological Studies Depression Scale (CES-D), a 12-item Short-Form Health Survey (SF-12), and Pittsburgh Sleep Quality Index (PSQI). Data were analyzed using descriptive statistics, one way ANOVA, and correlation. Results: Mean age of the participants was $59.91{\pm}12.63$ and mean physical activity levels were $1,660.35{\pm}1,654.17$. Patients who performed higher physical activities during their daily activities reported lower levels of depression (F=4.16, p=.018) and higher levels of QOL (PCS: F=5.00, p=.008, MCS: F=8.66, p<.001) than those of the others who did not perform physical activities. Conclusion: This study showed that the levels of physical activity among hemodialysis patients was significantly associated with their depression and QOL. Developing strategies for enhancing physical activity is warranted to improve depression and QOL among hemodialysis patients.

Objective : To investigate objectively the postoperative improvement of gait disturbance in patients with cervical myelopathy through a gait analysis. Patients and Methods : Ten patients who underwent cervical decompression and fusion for cervical myelopathy caused by spondylosis, OPLL, or concomitant hypertrophy of ligamentum flavum were studied. Preoperatively, gait disturbance was present in all patients. The patients were evaluated by gait analysis using three dimensional motion analyzer to collect data of linear and kinematic parameters before surgery, 1 week and 3 months after surgery. Statistical analysis of the related pre-and post-operative data were performed. Results : In the linear parameters, average value of cadence, walking speed, stride length, step time, width and double support were increased postoperatively compare to preoperative value. In the kinematic parameters, average value of knee flexion during initial swing phase, plantar flexion of ankle and range of motion of hip joint were increased as well. These differences were statistically significant(p<0.05). Conclusion : This study suggests that gait analysis can be used as a method of quantitative analysis of postoperative gait improvement in patients with cervical myelopathy.
