Purpose: We aimed to test the validity of the EQ-5D (Euro-Quality of Life-5 Dimension), a brief and simple instrument, in measuring health related quality of life in the patients with osteoarthritis. Methods: 183 participants attending the education programs for osteoarthritis patients at the Health Centers located in Seoul and Gyunggi province area during the periods of June to December in 2009 were interviewed with the EQ-5D and KWOMAC (Korean version of Western Ontario and McMaster Scale). The data were analysed with Spearman correlation coefficents and t-test by using of SPSS/WIN 12.0 version. Results: There was a negative correlation between knee pain, stiffness and difficulty in usual activity of sub category items of KWOMAC and EQ-5Dindex, while there was no correlation between these categories and EQ-VAS. Moreover, as a result of comparing the score of physical function measured by KWOMAC according to the severity degree of the EQ-5Dindex, the group of advanced stage having moderate and severe symptoms reported significantly higher scores of physical function than those of groups having no health problems. Conclusion: The EQ-5D is an acceptable and valid instrument for measuring health-related quality of life in patients with osteoarthritis.

This study was performed to probe the effect of exercise program on muscle strength, endurance, flexibility, pain, disability level and life satisfaction in female teachers of elementary school who complain of low back pain. For this study, 44 female teachers aged 30-50 years with mechanical low back pain of 6 months' duration, who had the structural normalities in the lumbar spine, were recruited from April 1 to July 10 1999. Twenty three out of them were assigned to the experimental group and twenty one to the control group. The exercise program consisted of education on right postures, the etiology and diagnosis of low back pain, and exercise intervention such as muscle relaxation, elongation and strengthening. With 8 weeks program, the subjects received two sessions of education and six sessions of group exercise in the 1st week, while three sessions of group exercise and four sessions of individual exercise weekly and two sessions of education during the later 7 weeks. The muscle strength and endurance were measured by Cybex 770, the flexibility by flexibility measurement machine, the intensity of pain by Visual Analogue Scale (VAS), the level of disability by Oswestry low back pain disability scale, depression by Beck depression inventory (BDI), and life satisfaction by Life satisfaction index-Z. Study measurements were taken before and after 8 weeks exercise program. Data were analyzed using paired t-test, t-test, and ANCOVA. The results were as follows ; 1. The flexors and extensors peak torque and flexors peak torque per body weight of experimental group were significantly increased at test velocities $30^{\circ}$/sec, $60^{\circ}$/sec compared with those of control group. There was no significant difference in extensors peak torque per flexors peak torque at $30^{\circ}/sec$, $60^{\circ}/sec$ between experimental and control group. 2. The flexors and extensors total work and flexors total work per body weight of experimental group were significantly increased at $120^{\circ}/sec$, compared with those of control group. 3.The flexibility of lumbar spine in experimental group was significantly increased compared with that of control group. The pains in anterior, posterior, left lateral and right lateral bending and in rotation of experimental group were significantly increased compared with those of control group. 4. The Oswestry disability scores of experimental and control group were significantly decreased, and there was no difference in the Oswestry disability score change between experimental and control group. 5. The scores of BDI of experimental group were significantly decreased compared with those of control group. Life satisfaction index-Z scores of experimental group were not changed, but those of control group were significantly decreased. There was no difference in the score change of Life satisfaction index-Z between experimental and control group. 6. ANCOVA analysis for the data variables of inhomogeneous baseline represented that there was no significant difference in extensors peak torque and extensors total work at $120^{\circ}/sec$ and extensor total work per body weight at $120^{\circ}/sec$ change between experimental group and control group. These findings indicate that the exercise program could be effective in increasing the muscle strength, endurance, flexibility and decreasing pain, improving depression in female teachers of elementary school with chronic low back pain. It is suggested that the exercise program could be an essential factor for the effective nursing intervention to the patients suffered from chronic low back pain.

The purpose of the study was to test the reliability and validity of the Korean version of Task Self-Efficacy Scale for activities of dally living (ADL). The Task Self-Efficacy Scale was developed by Roberts(1996) for low-intensity exercise study with older people to predict their performance of ADL. The scale was translated and back translated by bilingual persons, and then was modified to resolve variations in the translations. The Korean version of Self-Efficacy Scale for ADL was then administered to 193 elderly people including 95 hospitalized patients and 98 outpatients or healthy people. Face to face interview was used to fill out the structured questionnaire, and each interview took approximately 30 minutes. The subjects for the study were 80 women and 112 men with an age range of 65 to 95 years(M=71 years) of whom 82.6% classified themselves as moderate or quite active Most subjects(80.2%) had an education level of elementary school or less. The Self-Efficacy Scale for ADL is measured on a 0 to 10 VAS, assessing three areas of ADL : self care activities, household tasks, and motor tasks. The higher the score is, the higher person's confidence in performing ADL. Psychometric testing revealed that the scale was found to be internally consistent, showing a Cronbach's alpha of .97 The scale was significantly correlated with subjects' level of activity and subjective assessment of their health status. Moderate correlation with health-related hardiness scale also supported the validity. Factor analysis was performed to confirm whether the scale represents the three sub-areas as suggested in the literature. The results of the factor analysis led to a three factor solution according to Kaiser's criterion, but the items were not strongly and cleanly loaded for the third factor. This can be explained in that, among the three sub-ADL areas of the self-efficacy scale, the areas of self care activities and household tasks seem to have similar levels of difficulty in performance with not enough differences for the self-efficacy scale to distinguish between the two areas. Therefore, one factor solution was suggested since ADL can be seen as a unit of activities at similar level of difficulty in performance. One factor solution explained 68.1% of variance of the 19-item scale and all items were correlated over .6 with the factor, showing that the selected factor solution fits the model. The results indicated that the Korean version of Task Self-Efficacy Scale for ADL was reliable and valid in producing useful information to evaluate the effects of various interventions toward promoting health and quality of life for elderly people.

The aim of this study was to evaluate the efficacy of a topical 0.2% hyaluronic acid (HA) preparation in the management of wound after removal of arch bar for facial bone fracture and a suture site after orthognatic, oral cancer or oral surgery. Forty patients participated in a randomized, placebo controlled, double-blind trial to evaluate the efficacy of the topical HA and preparation. HA topically applied to the wound after removal of arch bar or stitch out, 3 times a day for 4 weeks. Evaluation is performed once a week for 4 weeks. For subjective evaluation, relative pain reduction in visual analog scale (VAS) and existence of heat sensation was accessed. For objective evaluation, gross evaluation, papilla index, existence of wound dehiscence, redness and swelling was checked. The same evaluation was performed in each arch bar group and suture group. For whole subject, 0.2% HA group resulted higher reduction than placebo group in pain of site in first week with significancy. Same findings were seen other weeks but there was no significancy. 0.2% HA group had better result than placebo in objective evaluation (papilla index, wound dehiscence, redness and swelling), but in gross evaluation placebo had better result than 0.2% HA group with no significancy. Subject was divided into suture group and arch bar group. Same aspect was seen, but only suture group had significancy not arch bar group in pain reduction score. 0.2% HA group resulted higher reduction than placebo group in pain of site in first week with significancy, especially in suture group. It reveals topical application of HA in wound especially suture site reduced pain in early stage. And 0.2% HA group had better result than placebo in papilla index, redness and swelling with no statistical significancy. In conclusion, HA has effect of pain reduction and healing promotion in the mucosal wound after oral surgery.

Purpose: This study was designed to verify preemptive effects of intravenous patient-controlled analgesia (IV-PCA) infusion on postoperative pain in women having a total abdominal hysterectomy. Method: The research design was a nonequivalent control group post test only design. The participants in this study were 50 women who were scheduled for a total abdominal hysterectomy at a University affiliated Hospital in Suwon, Korea. The subjects were divided into two groups. For the experimental group, IV-PCA infusion was started before the skin incision and for the control group. IV-PCA infusion was started after the skin was closed. Each group was evaluated in terms of pain score by the visual analogue scale (VAS) and the number of times they pushed the button for IV-PCA at postoperative hours 1, 2, 3, 6, 12, and 24. The data were collected from July 1 to December 10, 2001. Collected data was analyzed by SPSS/PC + program. Result: 1. There was no difference between the two groups, over six points for the number of times the control button for IV-PCA was used. Group differences and interaction effect were not significant. 2. There was no significant difference in pain scores between the two groups, over seven time points. A significant interaction effect was observed between groups and measurement Points in time. 3. There was a significant difference in the requirements for additional analgesia between the two groups, 32% of the control group received additional analgesia. Conclusion: Preemptive analgesics administration may have a better effect in relieving postoperative pain than the usual analgesic treatment which is started after surgery.

Background: Intraosseous anesthesia (IO) allows the anesthetic solution to be injected directly into the cancellous bone. The anesthetic solution immediately reaches the periapical region, and thus the axonal area of the nerve, where it can temporarily disable the sodium pump. The effect is felt almost without any time delay, and only a small amount of anesthetic solution is required. Methods: This study aims to investigate the efficacy of IO using the AnestoⓇ device after infiltration anesthesia (IA) and/or inferior alveolar nerve block anesthesia (IANB) failed to work in symptomatic irreversible pulpitis (hot tooth). The 33 patients included in the study were treated additionally with 1.7 ml articaine hydrochloride with 1:100,000 epinephrine hydrochloride (UltracainⓇ D-S, Sanofi-Aventis, Frankfurt, Germany) IO. Results: The electrical pulp test showed that 95.76% of the volunteers reacted positively to the combination of IANB or IA with the IO. In women, the additive IO was effective at 97.22%. In men, the IO led to pain elimination in 94.00% of cases. The duration of the IO was less than a quarter of an hour (13.03 min). The IO worked longer in women than in men (13.61 min vs. 12.33 min). Overall, more than every third tooth that needed trepanation was located in the posterior area of the mandible (36.4%). Treatment of hot teeth in this area was associated with an increased pulse rate and increased residual pain. There was a moderate correlation (Spearman-Rho [IRI] = 0.280) between the Visual Analog Scale (VAS) score and bone density, and a significant correlation (IRI = 0.612) between subjective residual pain and bone width. The IO resulted in a moderate, transient increase in the pulse rate by approximately 20 bpm. This is similar to the temporary increase in heart rate after conventional anesthesia techniques in non-preloaded patients and can be considered clinically irrelevant. Conclusion: IO with the AnestoⓇ device as an extension and deepening of local pain elimination is recommended for the treatment of hot teeth.

Objectives: In this study, the clinical characteristics of OSA patients and the quality of life before and after CPAP use were compared to determine the degree of improvement in quality of life according to CPAP use. Methods: Age, sex, height, weight, body mass index, Epworth Sleepiness Scale, Modified Mallampatti Score, Montreal Cognitive Assessment-Korean, and Pittsburgh Sleep Quality Index were compared between men and women through medical records. To understand the degree of improvement in quality of life resulting from use of CPAP, a personal telephone call was made to compare the VAS scores for quality of life before and after CPAP use. Results: In height (HT) (Z = -4.525, p < 0.001), weight (BW) (Z = -2.844, p < 0.05), sleep quality (PSQI) (Z = -2.671, p < 0.05), and arousal index (AI) (Z = -2.105, p < 0.05), there was a difference between men and women (p < 0.05). There was no difference in the remaining variables. Cross-analysis (Chi-square test) confirmed a difference between severity and sex of OSA. It has been found that there is no statistically significant order in size according to level-specific severity of OSA for PreCPAP QOL, PostCPAP QOL, CPAPUse Months, and CPAP4Hr/d (%) (p > 0.05). The difference between AHI before and after CPAP was 36.48 ± 21.54 (t = 11.609, p < 0.001) and the difference between QOL before and after CPAP was -25.43 ± 22.06 (t = -7.901, p < 0.001), both of which were significant (p < 0.001). Conclusion: Among OSA patients, there were differences in height (HT), weight (BW), sleep quality (PSQI), arousal index (AI), and severity of OSA between men and women, but the quality of life before and after CPAP was different. However, there was no difference between men and women in quality of life before and after CPAP. In addition, quality of life in OSA patients improved after using CPAP.
