  • A noble model of the whole lumbar spine (L1~L5) considering all the passive elements, especially the ligaments of the lumbar spine was developed. The purpose of this study was to investigate the relationship between the shear stress of the AVB and the ALL and the effect of a compressive follower pre-load on all ligaments with various motions. The result shows that the shear stress at the AVB and the ALL are positively correlated. This indicates that the shear stress of the ligament can be used an index of low back pain. Regarding the effect of a follower pre-load, contrary to our expectation, the shear stress of the ligaments was not always reduced by applying follower pre-load; flexion was decreased and axial rotation did not change, while extension and lateral bending were increased.

  • The relationships between nutrients intake, physical activity and bone mineral density were investigated in 19 elderly men aged 71-80 years. A trained nutritionist interviewed usual dietary intake and daily activity with a questionnaire, and bone mineral density was measured at the lumbar spine and three regions of the proximal femur (femur neck, Ward's triangle and trochanter) with a Luna DP3 dual photon absorptiometry. The correlations between dietary calcium intake and bone mineral density at the lumbar spine and trochanteric region were significant at P<0.05 and P<0.01 level respectively. the significant correlations were also found between vitamin A(P<0.005), riboflavin(P<0.01), and ascorbic acid(P<0.05) intake and bone mineral density at these sites. Higher physical activity was associated with greater bone mineral density of four sites, but this was not significant. But there were significant relationships between total energy expenditure and bone mineral density of the lumbar spine(P<0.01), femur neck (P<0.05) and Ward's triangle(P<0.05). In this study the results revealed that bone mineral density of the lumbar spine and trochanteric region were associated with dietary calcium intake. And bone mineral density of the femur neck and Ward's triangle were related to physical activity but not to nutrients intake. In conclusion, dietary calcium intake seems to be a important factor for greater bone mineral density. Further evidence will be needed that physical activity protects against bone fracture and osteoporosis in the edlerly.

  • This study was designed to investigate the effect of environmental an d physiological factors on bone mineral density(BMD) of the lumbar spine(L2longrightarrowL4) in 41 postmenopausal women. There were a positive relationships between BMD of the lumbar spine and monthly income food expenses pocket money energy expenditure(EXP) per day sociocultural EXP activity intensity time of standing and walking or age at first pregnancy. BMD of the lumbar spine was negatively correlated with age Engel index time of sleeping and sitting number of childbirty and children period of breastfeeding or menopausal period. But there were no significant relationships between BMD and physiological domestic EXP body mass index age at menar-che menstruation cycle or age at menopause. The complex interrelations between BMD and these variables were examined using stepwise multiple regression analysis. From this analysis in subject aged 50~59 years. EXP per body weight physiological EXP age at menopause time of sleeping were positively significant independent predictors of BMD. In subjects aged 60~69 years, . time of walking only and in total subjects. EXP per body weight pocket money were positively significant independent predictors ofBMD. This study suggest that EXP and pocket money are major constituents affection lumbar spine BMD in postmenopausal women.

  • Purpose : The purpose of this study is to analyze the corrective effect of the general coordinative manipulation (GCM) joint intervention model on distort leg with imbalance of the lower extremity joints, pelvic and shoulder girdles, and lumbar spine. Methods : The study used a comparative analysis of the size of the distort leg and the imbalance of the lower extremity joints, pelvic and shoulder girdles, and lumbar spine before and after the application of the GCM joint intervention model. A total of 31 subjects from movement center G and the department of physical therapy at university M were selected as research subjects, and they were divided into two groups. The GCM joint intervention model was applied to 18 subjects in the bow knee group and 13 subjects in the knock knee group. The two groups received daily intervention three times a week for four weeks. The corrective effect of the GCM joint intervention model for each type of distort leg was compared and analyzed. Results : The effects of the GCM joint intervention model in correcting bow knee and knock knee with knee deformation and imbalance of the lower extremity joints, pelvic and shoulder girdles, and lumbar spine were significant in most domains (p<.05). The correlation between the bow knee and knock knee groups showed significance in most domains (p<.05). Conclusion : The GCM joint intervention model showed significant corrective effect in the bow knee and knock knee groups in terms of knee deformation, lower extremity joints, pelvic and shoulder girdles, and lumbar spine (p<.05).

  • Objectives : The purpose of this study was to investigate the clinical effects of Korean medical treatments combined with acupotomy on patients diagnosed with a herniated intervertebral disc of the lumbar spine. Methods : We reviewed the medical records of twenty in patients diagnosed with a herniated intervertebral disc of the lumbar spine. They had received Korean medical treatment combined with acupotomy on tender points in the gluteus minimus muscle and piriformis muscle at Gwangju Korean Medicine Hospital of Dong-Shin University from April, 2014 to December, 2014. To evaluate the efficacy of the treatments, the twenty in patients were asked to complete the Numerical Rating Scale(NRS) and the Oswestry Disability Index(ODI) before acupotomy, the first day after acupotomy, the third day after acupotomy, and the fifth day after acupotomy. Results : 1. NRS significantly decreased from $6.15{\pm}1.27$ to $3.90{\pm}1.45$. 2. ODI significantly decreased from $23.64{\pm}8.76$ to $15.95{\pm}7.35$. Conclusions : Korean medical treatment combined with acupotomy on tender points in the gluteus minimus muscle and piriformis muscle might be effective in reducing pain and improving the life quality of patients with a herniated intervertebral disc of the lumbar spine. We hope that further studies will be done to produce more clinical data and ensure effective application of these results.

  • 나이에 의한 외부의 환경조건의 변화는 이에 적응하려는 척추의 구조적인 변화를 가져온다. 이러한 구조적인 변화는 척추의 biomechanical 거동에 영향을 미칠 것이다. 이러한 구조적인 변화의 효과를 연구하기 위하여, 나이에 의한 척추의 재료 및 기계적인 물성의 변화는 제외되었다. 유한요소법 (finite element method)에 의한 lumbar spine model (L3-L4)에 있어서, Annulus 의 유한요소 모델은 laminate composite elements로서 16개의 layer와 6개의 물성으로 구성되어있다. Spinal stiffness 와 facet reaction은 나이가 들수록 증가했다. 나이가 들수록 inner annulus의 fiber/layer tensile strains, cancellous bone stress 및 end-Plate stress는 감소했다. Fiber/layer compressive strains, facet reaction, ligament reaction and end-plate rigidity는 나이에 의한 척추의 구조적인 변화에 의하여 증가했다. 따라서 나이에 의한 척추의 정상적인 쇠퇴과정에 있어서 척추의 구조적인 변화는 spinal stiffness를 증가 시켜서 척추 및 disc의 지나친 변형을 감소시킬 것이다.

  • To evaluate the applicability of osteoporosis management by statistical analysis of the correlation between bone mineral density (BMD) changes after menopause by dividing the T-score of bone mineral density measured by dual energy X-ray absorptiometry do. Between January 1, 2016 and July 31, 2017, women who visited the medical center of W Medical Center were enrolled in this study. The postmenopausal period was divided into 5 groups, There were 18 patients within 5 years, 44 patients in 6~10 years, 134 patients in 11~15 years, 109 patients in 16~20 years and 21 patients in 21 years or older. And postmenopausal women. Bone mineral density (BMD) of the lumbar spine and femur was measured using a dual energy X-ray absorptiometry. The lowest value among lumbar spine 1, 2, 3 and 4 and the lowest value among the femoral neck, greater trochanter, total femur, and ward Values were measured. The statistical significance was analyzed by using bivariate correlation coefficient method and one - way ANOVA. In 326 patients who underwent BMD, the correlation between bone mineral density and postmenopausal BMD showed a negative correlation (-.159, p<.01) with BMD of femur and BMD of lumbar spine The correlation between the menopausal period and negative (-.208, p<.01) was shown. There was a significant difference (p<.012) between the postmenopausal femur bone density and the mean value of the lumbar spine BMD (p<.000). The relationship between bone mineral density (BMD) and postmenopausal women's postmenopausal status can be estimated by estimating the bone mineral density and using it as a basic data for osteoporosis management.
