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.
