| 目的：通过影像学研究颈椎后前向松动产生的椎间运动，分析其生物力学作用。方法：选取正常受试者12例,均采用多功能颈椎康复治疗仪给予后前向颈椎关节松动，力量为10~30N；松动前后，采用静态颈椎侧位片，比较运动节段矢状面的角度旋转及前后椎间隙变化。结果：松动后，C3~C6节段矢状面旋转角度均大于松动前（P<0.05）；C3、C5节段前椎间隙均显著大于松动前（P<0.05），C5节段后椎间隙显著小于松动前（P<0.05）。结论：后前向松动明显增加C3~C7脊柱的前凸，在伸展同时椎体产生旋转，前椎间隙增宽，后椎间隙减小。 |

| Objective:To study the cervical intervertebral movements following posteroanterior mobilization and the biomechanics.Methods:Twelve normal volunteers were recruited.All the subjects received posteroanterior cervical mobilization (10-30N for force).Before and after mobilization,cervical lateral slice at static state was used to test the sagittal rotation of motion segments and the posteroanterior displacement of posterior and anterior intervertebral separation (IVS).Results:After the mobilization,the sagittal rotation of C3-C6 were larger than that before (P<0.05);the anterior IVS of C3 and C5 was larger than that before (P<0.05);the posterior IVS of C5 was smaller than that before (P<0.05).Conclusion:The posteroanterior cervical mobilization significantly increased the lordosis of C3 to C7,and there is a rotation while the cervical is being extened,which leads to an increase of anterior IVS,but a decrease of posterior IVS. |
