Introduction : In patient with ankylosing spondylitis, when bone formation progresses, spinal fusion occurs and joint motion is severely limited. We performed Medical Gi-gong and Korean medical therapies in patient with advanced ankylosing spondylitis with spinal fusion. Case : 46-year-old male with extensive spinal fusion at the cervical and lumbar spine complains of back pain, hip pain, joint stiffness, eye pain, and digestive problems. HLA-B27 (+), mSASSS is 70. Medical Gi-gong was done 311 days for 340 days. Acupuncture, cupping, and manual treatment were performed once every 5.9 days for one year. BASDAI improved from 5.3 to 4.3, BASFI from 4.3 to 3.7, and BASMI from 6.8 to 5.8. mSASSS did not change. Conclusions : Patients with advanced ankylosing spondylitis were treated with Medical Gigong and Korean medical therapies to achieve a slight improvement.

Purpose：The purpose of this study was to investigate of the change of the forward head posture(FHP) according to computer using time. Methods：Subjects were 30 male and 30 female. The factors of FHP were measured cranial vertical angle, cranial rotation angle, and head, upper back, neck flexion/extension angle according to computer using time. Change of FHP used to Digital Inclinometry(JTech, Dualer IQTM Dual Inclinometer). The data were collected by data logger(Logger Teknologi HB, Akarp, Sweden). Results：Cranial vertical angle, cranial rotation angle, and head, upper back, neck flexion/extension were increased according to computer using time(p<.05). But cranial vertical angle and cranial rotation angle, and head, upper back, neck flexion/extension were not significant differences between male and female group(p>.05). Conclusion：The effects of cranial vertical angle, cranial rotation angl and head, neck and upper back angle depend on the computer task time. Increased of FHP may result increased tension in posture muscles of cervical spine, resulting in a risk of musculoskeletal disorders.

Ossification of the posterior longitudinal ligament (OPLL) can be defined as an ectopic ossification in the tissues of spinal ligament showing a hyperostotic condition. OPLL is developed mostly in the cervical spine and clinical presentations of OPLL are majorly myelopathy and/or radiculopathy, with serious neurological pathology resulting in paralysis of extremities and disturbances of motility lowering the quality of life. OPLL is known to be an idiopathic and multifactorial disease, which genetic factors and non-genetic factors including diet, obesity, physical strain on the posterior longitudinal ligament, age, and diabetes mellitus, are involved into the pathogenesis. Up to now, surgical management by decompressing the spinal cord is regarded as standard treatment for OPLL, although there might be the risk of development of reprogression of ossification. The molecular pathogenesis and efficient therapeutic strategy, especially pharmacotherapy and/or preventive intervention, of OPLL has not been clearly elucidated and suggested. Therefore, in this review, we tried to give an overview to the present research results on OPLL, in order to shed light on the potential pharmacotherapy based on molecular pathophysiologic aspect of OPLL, especially on the genetic/genomic factors involved into the etiology of OPLL.

We describe a case of a 71-year-old male patient who experienced progressive bilateral proximal upper limb weakness and atrophy without sensory symptoms and signs over 5 years. Electromyography demonstrated denervation potentials and neuropathic motor unit action potentials on C5-C7 myotome muscles bilaterally. Cervical spine magnetic resonance imaging revealed engorged anterior epidural venous plexus, T2 hyperintensity localized to grey matter ("snake-eye" appearance) at C2-C6 vertebral level, and ventral epidural fluid collection from C6 to T8 vertebral level. This case indicates that bibrachial amyotrophy associated with epidural fluid leak should be suspected in patients presenting with progressive bilateral upper limb weakness and atrophy without sensory involvement.

Background: Backpacks are one of the most widely used accessories in modern society. However, previous studies have shown that carrying a backpack can cause various musculoskeletal problems. Objectives: To investigate the effects of a body-adhesive backpack on craniovertebral angle, sagittal shoulder angle and the muscle fatigue in the upper extremity. Design: Randomized cross-over design. Methods: For this study, 36 healthy university students participated in this study. The experiment was conducted three times using common backpack, and body-adhesive backpack condition. The angles of the cervical spine and shoulder joints of the subjects were calculated without the backpack. Electrodes were placed at upper trapezius, lower trapezius, rectus abdominis and erector spinae to check for muscle fatigue. Subjects carried a backpack and walked on a treadmill for 15 minutes at 4 km/h. The muscle fatigue signal was also measured while walking. After walking, the craniovertebral and sagittal shoulder angles were measured again while subjects carried backpack. Results: As a result of this study, body-adhesive backpack condition showed significant decrease and significant increase in craniovertebral angle and sagittal shoulder angle than common backpack (P<.05). Body-adhesive backpack condition showed significant decrease in upper trapezius, lower trapezius, erector spinae, and rectus abdominis when compared to a common backpack (P<.05). Conclusion: This study suggests that a body-adhesive backpack is more beneficial in correcting body posture than a common backpack.

Purpose: Temporomandibular disorder (TMD) is a condition defined as pain and dysfunction of temporomandibular joints and masticatory muscles. Abnormal interconnections between temporomandibular muscles and cervical spine structures can cause the changes of postural alignment and balance ability. The aim of this study was to investigate changes in static balance ability in subjects with painrelated TMD. Methods: This study conducted on 25 subjects with TMD and 25 control subjects with no TMD. Pressure pain thresholds (PPTs) of the masseter and temporalis muscles were measured using a pressure algometer. Static balance ability was assessed during one leg standing using an Inertial Measurement Unit (IMU) sensor. During balance task, the IMU sensors measured motion and transfer movement data for center of mass (COM) motion, ankle sway and hip sway. Results: PPTs of masseter and temporalis muscles were significantly lower in the TMD group than in the control group (p<0.05). One leg standing, hip sway, and COM sway results were significantly greater in the TMD group (p<0.05), but ankle sways were not different between group. Conclusion: We suggest pain-related TMD is positively related to reduced PPTs of masticatory muscles and to static balance ability. These results should be considered together with global body posture when evaluating or treating pain-related TMD.

Purpose: This study was designed to evaluate the effects on bone mineral density (BMD) and related factors according to the distance from the radiation field at different sites. This study was conducted on patients with uterine cervical cancer who received pelvic radiotherapy. Materials and Methods: We selected 96 patients with cervical cancer who underwent determination of BMD from November 2002 to December 2006 after pelvic radiotherapy at Kosin University Gospel Hospital. The T-score and Z-score for the first lumbar spine (L1), fourth lumbar spine (L4) and femur neck (F) were analyzed to determine the difference in BMD among the sites by the use of ANOVA and the post-hoc test. The study subjects were evaluated for age, body weight, body mass index (BMI), post-radiotherapy follow-up duration, intracavitary radiotherapy (ICR) and hormonal replacement therapy (HRT). Association between the characteristics of the study subjects and T-score for each site was evaluated by the use of Pearson's correlation and multiple regression analysis. Results: The average T-score for all ages was -1.94 for the L1, -0.42 for the L4 and -0.53 for the F. The average Z-score for all ages was -1.11 for the L1, -0.40 for the L4 and -0.48 for the F. The T-score and Z-score for the L4 and F were significantly different from the scores for the L1 (p<0.05). There was no significant difference between the L4 and F. Results for patients younger than 60 years were the same as for all ages. Age and ICR were negatively correlated and body weight and HRT were positively correlated with the T-score for all sites (p<0.05). BMI was positively correlated with the T-score for the L4 and F (p<0.05). Based on the use of multiple regression analysis, age was negatively associated with the T-score for the L1 and F and was positively correlated for the L4 (p<0.05). Body weight was positively associated with the T-score for all sites (p<0.05). ICR was negatively associated with the T-score for the L1 (p<0.05). HRT was positively associated with the T-score for the L4 and F (p<0.05). Conclusion: The T-score and Z-score for the L4 and F were significantly higher than the scores for the L1, a finding in contrast to some previous studies on normal women. It was thought that radiation could partly influence BMD because of a higher T-score and Z-score for sites around the radiotherapy field. We suggest that a further long-term study is necessary to determine the clinical significance of these findings, which will influence the diagnosis of osteoporosis based on BMD in patients with cervical cancer who have received radiotherapy.

Background: In Korea, private health insurance has neglected to induce externality on national health insurance by moral hazard. Therefore, we conducted this study in order to explore the influence of private health insurance on unnecessary medical utilization among patients with cervical or lumbar sprain. Method: The study examined a population of 449 patients (admission, 384; out-patient; 85) diagnosed with simple cervical or lumbar sprain without neurological symptoms at 20 small hospitals or clinics in Gwangju and Jeollanam provinces from Jul. 1 to Aug. 31 2008. The data were collected using structured, self-administrated questionnaire which collected information such as whether or not the patient was admitted (as a dependent variable), whether or not they had private health insurance (as a independent variable), and covariates such as socio-demographic characteristics, the factors related to the sprain, and characteristics of the insurance provider. Results: From hierarchical multiple logistic regression analysis, it was found that the admission rate of patient with private health insurance was higher than that those without it (Odds ratio=3.31, 95% Confidence interval; 1.14-9.58), meaning that private health insurance was an independent factor influencing the admission of patients with these conditions. Other determinants of admission were patient age and physician referral. Conclusions: This study is the first empirical study to explore the influence of private health insurance on inducing moral hazard in admission services, specifically among patients with cervical or lumbar sprain. Regulation of benefits provided by private health insurance may be necessary, as the effect of this moral hazard may mean existence of externality.

This research has been conducted to provide the spinal cord injured patients with comprehensive necessity of and backup data for their rehabilitation in the community and make the aware of importance of overall community support to patients. The data was collected through questionnaire made to 83 patients charged to general hospital in Jeonbuk Province between 1 and 31 March 1997 to analyse the patients ability on activities of daily living through the research on general characteristics and Modified Barthel Index(MBI). As a result the outcome of the research was as follows : 1. Sexual distribution represented that 57 male (68.7%) and 26 female(31.3%) and in the age distribution majority group was 36 thirties (43.4 %) most active in social activities. 2. Analysis on occupation of patients showed majority group was in technicians, 21 people representing 25.4 % and the major cause of injury was traffic accident, 45people representing 54.2%, fall down, 17 people representing 20.5% and industrial accident, 13 people representing 15.7%, respectively. 3. In the multiple choice questionnaire on complications, the rate of appealing pain was highest and spasticity, pressure sore, contracture, depression which restrict the patients from activities of daily living ability were also appeared. 4. The theoretical points in MBI Should lie between 1 and 115 and the average point be 58 but the average point of the MBI among 83 patients was 63. 5. The MBI point by the level of injured represented statistically critical difference(P<0.001) and the MBI points tested by Duncan's Multiple Area Testing in lumbar(80.1) and in thoracic (65.8) represented critically higher than the one in cervical(42.5). 6. In the distribution of the method of Urination after spine injury, the intermittent catheterization represented highest numbar of 34(41.1 %). Testing by Duncan's Multiple Area Testing, as we found the critical difference in the analysis on MBI points(P<0.001), the point in independent self voiding patients ($90.87{\pm}29.34$) was higher than the one in other self voiding patients(P<0.05). 7. In th category of social activities after spine injury, the number of people classified in others, 41 people representing 49.5% was highest and in the MBI points of the spinal cord injured people in religious activity, hobby activity, private club, occupation was critically higher than the people classified in miscellancous(P<0.01) who are the spinal cord injured people and mostly depend on their family's assistance at home in their daily activities.
