| EN Abstract: |
| 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. |
