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. Conclusions: Results from this study indicate that distinct difference exist among patients and controls and gender, whereas little difference exists in age and working posture.

Lumbar Lordosis Angle (LLA) is an index that can be used to evaluate the curvature of the lumbar vertebrae. It can measure the structural stability of the lumbar spine and the stability of each segment of the vertebral column at the intervertebral disc angle (IDA). Especially, our data shows it is found to be a strong positive correlation between obesity and the angle of lordosis for lumbar vertebrae. Also, the reason for the large IDA in the case of obesity seems to be the result of the weakening of anatomical structure as well as the gravity effect. And, the obesity interferes with normal sagittal balance and fails to maintain a straight posture with minimal energy. Therefore, the obesity can be an important factor in causing back pain by changing the lumbar lordosis.

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.
