Purpose: The purpose of this study was to evaluate effects of lumbar vertebrae mobilization and lumbar stabilizing exercises on the muscle strength. Methods: The subject were sixty healthy adult(30 females. 30 males) two decade from 21 to 35. All subjects randomly assigned the control group, lumbar vertebrae mobilization group, lumbar stabilizing exercises group. lumbar stabilizing exercises group received lumbar stabilizing exercises for 30 minutes, lumbar vertbrae mobilization group received lumbar vertbrae mobilization for 4-5 minutes per day and three times a week during 3 weeks period. BIODEX was used to measure muscle strength. All measurements of each subjects were measured at pre-experiment, after 10 day, and post-experiment. Results: The results of this study were summarized as follows; 1. The flexion strength test of control group, lumbar vertebrae mobilization group, lumbar stabilizing exercises group were no significantly differences at pre-experiment and after 10 days(p> .05), however significantly increased post-experiment(p <.05). The result of analyzed effects of flexion strength test was significantly increased accordining to experiment type(p <.05). 2. The extension strength test of control group, lumbar vertebrae mobilization group, lumbar stabilizing exercises group were no significantly differences at pre-experiment and after 10 days(p> .05), however significantly increased post-experiment(p <.05). The result of analyzed effects of extension strength test was significantly increased accordining to experiment type(p <.05). Conclusion: conclusionally these data suggest that a 3-week lumbar stabilizing exercises improved muscle strength. Additional randomized controlled trials to more fully investigate trement effects and factors that may mediate these effect are needed.

Objective: Studies confirming the lumber spine kinematics of direct or indirect segmental mobility under the application of joint mobilization, which induces passive force on the spine, are insufficient.Therefore, this study aims to obtain the underlying clinical data by identifying direct or indirect segmental mobility produced by Maitland's PA mobilization technique. Design: Randomized controlled trial design. Methods: Thirty subjects with no back pain participated in this study. X-ray testing equipment (SIG-40-525, Ecoray Inc., Korea) was used to verify the segmented movement of their lumbar. Joint mobilization was performed by physiotherapists with more than 10 years of experience in prescription therapy, and radiography was performed once without PA joint mobilization and once without the mobilization for comparing the lumbar vertebrae before and after the mobilization. The radiographs taken were analyzed using the picture archiving and communication system (PACS) program to measure the spinal displacement, intervertebral height, intervertebral angle, and lumbar lordosis angle. Results: Significant differences were observed in the lumbar displacement, intervertebral angle, and lumbar lordosis angle in all lumbar vertebrae before and after the mobilization. The intervertebral height indicated significant differences in all ventral vertebrae and only in L3-L4 and L4-L5 in dorsal vertebrae. Conclusions: This study suggests that the segmental mobility produced through indirect approaches plays an important role in inducing therapeutic effects in patients with 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.

Background: The purpose of this study was to investigate the relationship between the spine and the flat-foot, the stability and the alignment of the posture of the neck to prevent the alignment of the ankle joint operation and the lower back flexibility of the lumbar region according to the type of treatment using active stretching of the triceps, back pain, and to see how they affect weight bearing differences. Methods: The subjects of this study were 24 chronic low back pain patients. They were randomly divided into experimental group and control group. In the experimental group, ankle joint mobilization and active scraping of triceps were performed three times a week for a total of 6 weeks. The control group was performed in the same way without articulation. The range of flexion and extension motion of the lumbar spine and pain degree and difference of weight-bearing were measured before and after the experiment. Results: The model of ankle joint mobilization and calf muscle elongation of flat foot significantly improved the range of flexion and extension motion of the vertebrae (p<.05) and the VAS and distribution of weight-bearing were decreased in both of two groups (p<.05). In other words, the exercise and mobilization help to recover of the balance of the whole musculoskeletal, the vertebrae. Conclusions: The active exercise of the triceps muscle of the lower leg in this study It affects the flexibility of the lumbar spine, the pain and the difference in the weight support of the lower extremities, when we performed ankle joint mobilization for exercise and cramping, pain and the difference in weight support between the two lower limbs.
