The purpose of this study is to analyze the phases of back pain occurring on pregnant women, and to raise the necessity of the pain management on the basis of the former analysis. The objective group is 284 pregnant women who visited department of OBGY of hospital located both in Seoul and Andong. The results are as follows; 1. 204(71.8%) pregnant women were suffering from back pain. The ratio of pain occurrance in terms of the duration of pregnancy shows that 78.3% within 3 pregnant months, 68.4% between four and six months and 72.1% over seven month. Most common ares of pain was low back area rating 60.5%. 2. The most painful postural for the suffering women was lying on the back rating 35.9% and the next painful posture was standing rating 34.4%. And the most painful movement was to maintaining continues movement(57.8%). Twisting back rates the second(17.2%). These two variables were relevant each other(p<0.05). 3. 46.7% of pregnant women were experiencing nocturnal pain. Among women experienced the pain before pregnancy, 39.9% were suffering during the pregnancy. The occurrence of nocturnal pain was related to the pain before and after the pregnancy(p<0.05). 4. 58.8% of pregnant women who experience back pain take the pain for granted as a normal proceeding of pregnancy while 3.9% recognize the symptom as an abnormal. Pain recognition in accordance with the phases does not show much difference(p<0.05). 5. It is shown that the more one delivers the number of babies, the faster back pain occurs(p<0.01). 6. 32.3% of the pain-suffering women have family member(s) having back pain. Family member(s) of the women who does not experience the pain don't have the pain either. This case reports 46.1%. Statistically, these two variables are relevant(p<0.01). 7. 43.0% of back pain experiencing women does not have any particular management plan against the pain. 20.7% is exercising as for prevention. Women who recognize the necessity of some means of therapy for their pain marked 42.9%. The majority(65.8%) of women responded exercise gymnastic work-out are most appropriate pain management. The above results show that a great number of pregnant women is experiencing back pain, however, they properly managed. This span suggests that appropriate advocacy and education for pregnant women is necessary. It is recommended that positive contribution can be made to better health of pregnant women when pain management by physical therapist is given.

Purpose: Recently, various metal primers have been developed, and these are known to increase the bond strength between metal and relining resin. In this study, the change in bond strength according to amount of thermocycling was evaluated. Materials and Methods: In this study, 216 specimens were fabricated. Tokuyama Rebase $II^{(R)}$(Tokuyama Corp., Japan) and $Kooliner^{(R)}$(GC America Inc., Japan) as relining material, and MR. $Bond^{(R)}$(Tokuyama Corp., Japan) and Alloy $Primer^{(R)}$(Kuraray Medical Inc., Japan) as a metal primers were used. Using Ni-Cr and various metal surface treatment methods, resin was bonded and the change in bond strength during thermocycling was measured. The data was analyzed by one-way ANOVA, t-test(p<.05 level of significance). Results: When comparing the groups with only sandblasting, rapid decrease in shear bond strength could be seen. In the groups using Tokuyama Rebase $II^{(R)}$, with the exception of the 1000 and 2000 cycle groups, each group showed statistically significant decrease in shear bond strength(p<0.05). In comparison according to relining materials, $Kooliner^{(R)}$ showed higher shear bond strength than Tokuyama Rebase $II^{(R)}$ in all groups. In groups using MR $bond^{(R)}$, $Kooliner^{(R)}$ had higher shear bond strength than Tokuyama Rebase $II^{(R)}$ but, there was no statistical significance(p<0.05). In the other groups, $Kooliner^{(R)}$ showed significantly higher shear bond strength(p<0.05). There was significant difference between groups with sandblasting and metal primer treatments(p<0.05). In comparison according to metal primer materials, Alloy $Primer^{(R)}$ showed the highest shear bond strength but there was no statistical significance(p>0.05). According to the number of thermocycling cycles, when using Tokuyama Rebase $II^{(R)}$, there were no significant differences between the 0, 1000 and 2000 cycle groups regardless of the type of metal primer. There were no differences between the 2000 and 3000 cycle groups. When using $Kooliner^{(R)}$, regardless of the type of metal primer, there were no significant differences between the 0, 1000, 2000 and 3000 cycle groups(p>0.05). Conclusion: The use of metal primers showed increase in bond strength, and the stability after to thermocycling has been authenticated. Thus, the use of metal primers in relining and rebasing of metal frameworks is essential. But when selecting the material various physical properties should be considered.

Muscle weakness in the hemiplegia following stroke is an important factor which determines the quality of life in the future. Therefore, muscle strengthening exercise is essential for functional recovery in hemiplegic patients. Even though the popular conception is that muscle strengthening exercise causes spasticity and associated reaction that hemiplegia patients don't want, and that it disturbs functional recovery, recently there have been many new reports against that opinion. Therefore, the effects of strengthening exercise programs on functional recovery in hemiplegic patients are still controversial. The purpose of this study was to determine the effects of strengthening exercise programs for the knee joint using isokinetic exercise on the associated reaction of the upper extremities. Comparing the muscle activities of biceps brachii and triceps brachii during, before, and immediately after 2 and 5 minute intervals of isokinetic exercise, we examined the increase and decrease of associated reaction. Twenty stroke inpatients participated in this study. Surface electromyography was used to get muscle activity data from biceps brachii and triceps brachii. The major findings of this study were as follows: 1. The flexor and extensor peak torque were significantly higher on the sound side than the affected side (p<.05). 2. Before and after strengthening exercise, there was no significant difference in muscle activities (surface electromyographic root mean square values) between the sound and affected side. 3. Muscle activities were examined during, before, and immediately after 2 and 5 minute intervals of isokinetic exercise. There were significant differences in muscle activities between, before and during the exercises, during exercise and 5 minutes after exercise in the biceps brachii (p<.05), and during exercise and 5 minutes after exercise in the triceps brachii (p<.05). In conclusion, there was no relation between strengthening exercise and associated reaction in the upper extremities. Rather, muscle activities after exercise had a tendency to decrease relative to before the exercise. Thus, it is considered that intensive strengthening exercise contributes to improvement of functional recovery without increase in associated reaction in hemiparetic patients.

This study was designed 10 investigate the effects of therapeutic gymnastic ball exercise on pain, flexibility, lumbar disability level and daily activity levels in male patients of the armed forces medical hospital who complain of chronic low back pain. Twenty-three males were placed in the experimental group and twenty-nine males were placed in the control group. All of the subjects were chosen on the basis of availability among in-patients who were diagnosed with low back pain. The control patients were matched to the experimental group and they were selected considering gender, pain duration and age. Gymnastic ball exercise therapy was developed by the author with the assistance of a rehabilitation specialist. Gymnastic ball exercise therapy includes muscle relaxation, flexibility, muscle strength and posture development exercises. The gymnastic ball exercise therapy was carried out by the experimental group three times a week for eight weeks. Before and after the experiments, the intensity of pain, the lumbar joint mobility (flexibility), the lumbar disability levels, and the daily activity levels of the subjects were measured, respectively. The intensity of pain and the lumbar disability levels were measured by the Visual Analogue Scale, the level of flexibility by a measurement ruler, and the level of disability by the Oswestry Low Back Pain Disability Scale. Data were analysed using a t-test, a paired t-test and an unpaired t-test. The results were as follows: 1. The intensity of pain in the lumbar spine in the experimental group was significantly decreased compared with that of the control group during the 4th week and 8th week. 2. The flexibility of the lumbar spine in the experimental group was significantly increased compared with that of the control group during the 4th week and 8 week. 3. The level of pain caused by anterior, posterior, left lateral and right lateral bending and by rotation in experimental group was significantly decreased compared with that of the control group. 4. The Oswestry Disability score of the experimental group was significantly increased compared with that of control group. These findings indicate that gymnastic ball exercise therapy could be effective in decreasing pain and lumbar disability, and increasing the daily activity levels and lumbar flexibility in patients with chronic low back pain. The study also suggests that gymnastic ball exercise therapy could be an essential factor for effective nursing intervention for patients suffering from chronic low back pain.

Background: The International Classification of Functioning, Disability, and Health-core set (ICF-core set) for children and youth (CY) with cerebral palsy (CP) provides a useful conceptual framework and a guide for health care planning and measuring the changes brought by interventions across a multitude of dimensions from body functions to personal activities, social participation, and environmental factors for them. Objects: This single case study was reported to illustrate the use of a goal directed approach in applying the ICF-core set for CY with CP from a physical therapist perspective. Methods: An eleven year old boy with spastic CP, Gross Motor Function Classification System (GMFCS) level V, and his mother participated in an evaluation of his functioning state. The intervention goal was set through an interview using the ICF-core set, Canadian Occupational Performance Measure (COPM) and Goal Attainment Scale (GAS). Physical therapy was carried out on an outpatient basis using a goal directed approach for 30 min, 1 time/week during 12 weeks and the boy's gross motor function was assessed using the Gross Motor Function Measure (GMFM)-66 version (item set 2) before and after the intervention. Results: As measured by the boy's mother, the COPM score showed a meaningful clinical change (performance=mean 3.5, satisfaction=mean 2.5) and the T-score of GAS changed 34.4 after the goal directed approach. The GMFM-66 (item set 2) score changed from 31.8 to 38.7 and evaluation using the ICF-core set displayed improvement in 6 items of activity level between before and after the intervention. Conclusion: The ICF-core set for CY with CP is useful for understanding the overall functioning of CY with this condition and provides an opportunity to share and integrate information and opinions from different disciplines. We consider it as a useful tool in the universal language for the therapy and education of CY with CP.

A case is described, where an adolescent boy developed alopecia areata and alopecia totalis during the course of routine orthodontic treatment for the resolution of a dentoalveolar Class II division 1 malocclusion. The orthodontic treatment lasted 22 months, with a successful outcome. However, within eight months of the onset of treatment the patient lost all his hair Exhaustive medical tests and differential diagnosis determined that the etiolgy of the patient's alopecia was psychological stress evoked by the orthodontic treatment. Numerous reports suggest that psychological stress can cause alopecia by affecting the immune system. Therefore, it appears reasonable to assume that in the case of this patient, alopecia had resulted from stress effects on the immune system, leading to autoimmune disease-like conditions in tissues surrounding the scalp hair follicles. The alopecia condition was successfully reversed by daily oral and topical applications of vitamin D. It is concluded that the immune system plays a pivotal role in tissue remodeling around the teeth and elsewhere in the body, and that any conditions capable of affecting this system may cause unfavorable outcomes, such as alopecia.

This present study was designed to screen medicinal plants for the treatment of brain diseases such as Parkinson's disease or aging. We tested the effects of the water extracts from 38 species medicinal plants on antioxidant capacity, monoamine oxidase B (MAO-B) inhibitory activity, acetylcholinesterase (AChE) inhibition and antiperoxidation activity in vitro. The water extracts from 38 species were tested on their antioxidant activity using radical scavenging effects against ABTS+. The water extract of C. sappan was showed the highest antioxidant capacity, the antioxidant activity at 1 Jig of herbal extract being 0.38mM TE. Lipid peroxidation in brain homogenates induced by NADPH and ADP-Fe/sup 2+/ was strong inhibited by C. sappan and R. palmatum extracts. Among the 38 medicinal plants investigated, R. palmatum showed significant biological activity (antioxidant capacity, MAO-B inhibiory activity, and AChE inhibitory activity). The protective efficacy of R. palmatum water extract on 1-methyl-4­phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced parkinsonism and its possible mechanism were studied in C57BL/6 mice. Treatment of R. palmatum water extract protected biomacromolecules such as lipids from oxidative damage induced by MPTP. The content of MDA in brain tissue was decreased significantly by R. palmatum extract. These results suggest that R. palmatum water extract plays on effective role in attenuating MPTP-induced neurotoxicity in mice. This protective effect of R. palmatum might be estimated the result from the inhibitory activity on monoamine oxidase B and the enhancement of antioxidant activity.

Neck pain was commonly experienced by both adolescents and adults. The neck disability index(NDI) was the most commonly used self-report measure for evaluating status in neck pain. The objective of this study is to research the prevalence of the NDI in their 20's of college students in department of physical therapy. The data were collected from the NDI questionnaire of college students(males: 229, females: 405) for functional disability measures. Statistical analysis was carried out with SPSS 12.0 program, which was used for descriptive statistics, independent samples test and Pearson correlation analysis. The results were : First, 'headache' item was showed 'the highest prevalence' in second choice demonstrating the neck disability and 'pain intensity' in third choice. Second, female(46.4%) was higher distribution than male(36.3%) on score, percentage and grade of NDI(p<0.05). Third, the NDI grade was investigated that it is composed of 'no disability(63.8%)', 'mild disability(35.4%)', and 'moderate disability(0.9%)' in male and 'no disability(53.6%)', 'mild disability(44.7%)', 'moderate disability(1.5%)' and 'severe disability(0.2%)' in female. Fourth, there was a statically significant relationship between NDI grade and NDI items(p<0.05). These results have specific meaning as future clinical and epidemiological studies. Also, it is needed to education and preparation on prevention and management of neck disability among college students.

Purpose : This study was done to examine the actual effect of the scapular position in these flexibility tests. The purpose of this study was to examine the differences between the measurement of SRT(Sit-and-Reach Test) without intentional abduction of the scapular (pre-test) and with intentional abduction of the scapular (post-test). The hypothesis is: 1. There is no differences in the SRT result of the pre-test and the post-test. 2. There is no differences in the HJA(Hip Joint Angle) result of the pre-test and the post-test. 3. There is no differences in the Spine Motion Test(SMT) result of the pre-test and the post-test. Method : The total 60 people (30 men, 30 women) were participated in this study. In the pre-test, the subjects were asked to sit on the examination table and try the SRT motion; and then the HJA, SRT and the SMT numerical values were taken. In the post-test. the subjects were instructed to intentionally bring the scapula outward from the midline; and the HJA, SRT and the SMT numerical values were taken. Result : In the pre-test. the SRT result averaged 34.17cm. and in the post-test. the SRT result averaged 36.68cm. The difference was about 2.81cm which showed a significant mean statistically (p<0.01). The measurement increased by 8.22%. The HJA was $85.9^{\circ}$ in pre-test, and it was $85.5^{\circ}$ in post-test. giving the $0.4^{\circ}$ differences. Therefore, it didn't have a statistical mean (p>0.05). The SMT value was 69.56cm in the pre-test. and it was 69.28cm in the post-test, about 0.28cm decreased. Therefore, it didn't have a statistical mean (p>0.05). SRT values and HJA values were correlated (p<0.01). SMT values and SRT values (p<0.01), and SMT values and HJA values(p<0.05) were each in counter correlation. Conclusion : The result of the SRT without intentional scapular abduction (34.17cm) and with intentional scapular abduction (36.68cm) showed a significant increase about 8.22% (p<0.01). In SRT, the effect of the intentional scapular abduction on SMT showed no significant means, the pretest value being 69.56cm and the post-test value being 69.28cm (p>0.05).

The purpose of this study was to examine the amount of $\beta-endorphin$ and pain threshold according to time sequences in applying experimented TENS and MENS(pre treatment, posttreatment, 25 minutes after the treatment). This test was to aim at showing the effects of the experimental $\beta-endorphin$ and pain threshold applied to the randomly selected twenty healthy men in their twenties. The subjects were divided into two group(ten for TENS and the other ten MENS). The results obtained are as follows : 1. There was no significant difference in the $\beta-endorphin$ between TENS and HENS(p>0.05). There was no difference in the pain threshold at pretreatment and posttreatment(p>0.05), but there was some difference at 25 minutes after the treatment(p<0.05). 2. The group of TENS in the experimental $\beta-endorphin$ had the highest level of $14.40{\pm}3.098$ at posttreatment, but the level decreased a little according to time passed. And in the experimental pain threshold, the level went to the highest plateau of $2.92{\pm}0.483$ at 25 minutes after the treatment. 3. The group of MENS in the experimental $\beta-endorphin$ had the highest plateau of $14.20{\pm}3.967$ at posttreatment, but the level decreased a bit according to time passed also. And in the experimental pain threshold, the level went to the highest plateau of $2.49{\pm}0.617$ posttreatment. 4. There were some differences of the experimental $\beta-endorphin$ in TENS group at pretreatment and posttreatment(p<0.05). There were some differences in the experimental pain threshold between pretreatment and posttreatment as well as between pretreatment and 25 minutes after the treatment(p<0.05) MENS did not influence the experimental $\beta-endorphin$ and pain threshold. This experiment showed that TENS increased the levels of the experimental $\beta-endorphin$ at posttreatment and increased the levels of the experimental pain threshold untill 25 minutes after the treatment. Therefore, the time of sustaining pain in TENS group was longer than that of MENS group. Also, MENS showed that it increased each level of the experimental $\beta-endorphin$ and pain threshold, but these levels were not statistically meaningful.
