ABSTRACT
<p><b>OBJECTIVE</b>To observe and compare the clinical effect of Dingweiban and Xieban manipulation, and to compare the change of the deviation of spinous processes between two methods.</p><p><b>METHODS</b>One hundred and twenty-two cases were divided into two groups. Sixty-two cases were treated with Dingweiban manipulation method and 60 cases by Xieban manipulation. The changes of Fairbank scores, the clinical effects and the difference of the deviation of the spinous processes (L3, L4, L5) from the lumbar posterior-anterior X-ray were compared.</p><p><b>RESULTS</b>The scores before and after treatment and 3 months after treatment were compared. There were significant differences between two groups (P < 0.05) by nonparametric test. The result of Dingweiban manipulation group: 53 cases cured, 5 cases better, 3 cases effective and 1 case no effect. The result of clinical Xieban manipulation group: 43 cases cured, 6 cases better, 7 cases effective and 4 cases no effect. The clinical effects had significant differences after treatment and 3 months after treatment (P < 0.05, P < 0.0l) by nonparametric test. After the first treating, there was clear difference of the deviations' distance of the L4 spinous process compared with the Xieban manipulation group (P < 0.05). After the last treating, there were clear differences of the deviation distance of the L4 and L5 spinous processes compared with the Xieban manipulation group (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>Dingweiban manipulation is better than Xieban manipulation in effects and has influence on the deviation of spinous processes, especially for the L5 spinous process.</p>
