Objective : Obesity is associated with degenerative arthropathy giving stress on joints. It also amplifies loads of weight bearing joints by changing the gravity line of the body. Our aim is to investigate the correlation between obesity and lumbar lordosis in obese pre-menopausal Korean females. The hypothesis was tested that there is a correlation between obesity and lumbar lordosis. Methods : A cross-sectional evaluation of 44 Females (baseline age 30.77 ± 6.46) with BMI 31.53 ± 3.82 (kg/㎡) was done. Body composition was measured using bio-impedance analysis (BIA), and anthropometry was done by the same observer. A lateral whole spine X-ray was taken in standing position to measure the lumbar lordotic angle (LLA), Ferguson angle (FA) and lumbar gravity line (LGL). A Pearson correlation was used to measure the correlation between obesity and lumbar lordosis (SPSS 10.0 for windows). Results : Body mass index (BMI kg/㎡) had a negative relationship with LLA((equation omitted)=-0.469), FA((equation omitted) =-0.347) and LGL((equation omitted)=-0.389). Body fat rate had a negative relationship with LLA only(γ=-0.385). Waist circumference had a negative relationship with LLA((equation omitted)=-0.345) and LGL((equation omitted)=-0.346). WH ratio had no relationship with lumbar lordosis. Conclusion : These data show that obesity is related to mechanical structures, such as lumbar lordosis. BMI was the most useful index, which reflects a change of mechanical structure of lumbar, more than other variables in this study.

Objectives: The purpose of this study was to compare the difference of Lumbar Lordosis Angle (LLA)between patients with Low Back Pain (LBP) and control groups. Methods: Questionnaires were completed by 40 adults LBP patients seeking physical therapy services and by 40 controls at the department of Physical Therapy, SaeJong Neurosurgical Clinic in Taegu city, South Korea from October 1999 to March 2000. LLA was measured on lateral x-ray films with standing position. The angle between a line parallel to tile top of the first Lumbar (Ll) and the top of the fifth Lumbar (L5) was defined LLA. Results: LLA of 29.88$^{\circ}$ for LBP patients was statistically significant decrease from that of 35.31$^{\circ}$ for controls in the difference of lumbar lordosis (p<0.01). There were statistically significant differences between genders in patients groups. Females(32.22$^{\circ}$) had significantly greater angles than males (27.32$^{\circ}$) (p<0.05), while 36.63$^{\circ}$ for female was also greater than 34.12$^{\circ}$ for male in the controls. No significant difference was found between age. In patient groups, 27.95$^{\circ}$ for below age 40 was a smaller than 32.32$^{\circ}$ for above, however, 35.82$^{\circ}$ for below age 40 was a little greater than 34.27$^{\circ}$ for above in controls. Patients in sitting posture had greater LLA (31.35$^{\circ}$). than those standing (28.93$^{\circ}$), however. values for controls were similar to each other.

허허리뼈 전만각(LLA)은 허리뼈의 곡률을 평가하는 데 사용할 수 있는 지표이다. 허리뼈의 구조적 안정성과 추간판 각도(IDA)에서 척추의 각 부분의 안정성을 측정할 수 있다. 특히, 본 연구 자료에 따르면 허리뼈에 대한 비만과 전만각 사이에는 강한 양의 상관관계가 있는 것으로 나타났다. 또한, 비만의 경우 IDA가 큰 이유는 해부학적 구조의 약화와 중력 효과의 결과인 것으로 보인다. 비만은 정상적인 시상면 균형을 방해하고 최소한의 에너지로 똑바른 자세를 유지하지 못한다. 따라서 비만은 허리뼈 전만증을 변화시켜 요통을 유발하는 중요한 요소가 될 수 있다.

Purpose: This study examined the effects of sling exercise therapy on vertebral alignment, VAS, muscle activity, and multifidus of patients with chronic low back pain. Methods: Simple random sampling was used to divide the patients (n=116) into the sling exercise therapy group (SETG) and conservative physical therapy group (CPTG), with each group provided a intervention program in 3 sessions a week for 12 weeks. The lumbar lordosis angle (LLA), lumbar intervertebral disc angle (LIVDA) for vertebral alignment, lumbar muscle activity, and multifidus atrophy were measured before and after the intervention. Results: SETG showed significant changes in LLA, LIVDA of rate of change (delta score), and in relieving pain. The right-left balance gap for the lumbar dynamic muscle activity decreased after the intervention. The SETG showed significant changes in the grade of lumbar multifidus atrophy. Conclusion: The sling exercise therapy program is an effective exercise therapy method on vertebral alignment, muscle activity, recovery from multifidus atrophy, and pain relief for patients with chronic low back pain.

Objective: The purpose of this study was to characterize the movement of adjacent segments that occurred when posteroanterior joint mobilization was applied to the 3rd lumbar and thereby to provide basic clinical data. Design: Randomized controlled trial design. Methods: While the subjects were receiving posteroanterior joint mobilization of the 3rd lumbar vertebra, LD (lumbar displacement), LID (lumbar intervertebral distance), LIA (lumbar intervertebral angle), and LLA (lumbar lordosis angle) were measured using X-ray, and the data were then analyzed. Changes before and after posteroanterior joint mobilization were analyzed using a paired-sample t-test, and a one-way ANOVA of variance was performed to determine the difference between segmental movements. In addition, Pearson's correlation analysis was performed to determine the correlation between segmental movements. Results: The results revealed that there was a significant change in LD before and after the application of joint mobilization of the 3rd lumbar in all lumbar vertebrae (p<0.000), among which the 2nd lumbar vertebra, an adjacent segment, showed the most significant change. A significant change in LIA angle was observed in all segments (p<0.000), with the most significant change observed between the 2nd and 3rd lumbar vertebrae. There was a significant change in LLA before and after the application of posteroanterior joint mobilization (p<0.000). The correlation analysis showed a high correlation between displacement of the 3rd lumbar vertebra and displacement of all the other lumbar vertebrae. Conclusions: The presence of kinematic movements of the lumbar vertebrae when segmental movements were generated through the application of posteroanterior joint mobilization of the 3rd lumbar vertebra.
