自体牵引对正常人腰椎间隙的影响

Effect of autotraction on lumbar intervertebral space in normal persons

目的:①观察不同角度自体牵引对正常人椎间隙宽度的影响,确定自体牵引治疗的有效性。②观察不同角度自体牵引对正常人血压、脉搏的影响,确定自体牵引治疗的安全性。方法:选择健康卫校学生20名,牵引前先拍腰椎侧位片,然后将牵引床倾斜至60°进行自体牵引,间隔5天将牵引床倾斜至90°进行二次牵引,牵引时间20min,牵引后立即拍腰椎侧位片。取牵引前、60°、90°牵引后腰椎侧位片。结果:牵引前与两种角度牵引后比较,牵引后各腰椎间隙宽度不同程度增加,均有显著性差别(P<0.05);60°牵引后与90°牵引后比较,各腰椎间隙宽度无显著性差别(P>0.05)。结论:60°自体牵引与90°自体牵引后均可以使腰椎间隙增加,且牵引过程中血压和脉搏无过分升高,是治疗腰椎间盘突出症等下腰痛有效且安全的方法,两种角度自体牵引疗效无显著性差异。

Objective： ①To observe the effect of autotraction on lumbar intervertebral space in normal persons from different angles;②To exlpore the effect of autotraction on blood pressure and pulse in normal persons from different angles, and then determine the safety of autotraction therapy. Method：Twenty healthy students were chosen from a nursing school. Before autotraction, L-Spine LAT were obtained. Then the traction bed was tilted up to 60° slowly. The participant was hanged off the bed and autotractioned by gravity. The traction lasted 20 minutes. L- Spine LAT was taken immediately after the traction. The procedure was repeated 5 clays later with the same method, just tilting the traction bed to 90°. Result：The width of each lumbar intervertebral space after autotraction with the angle of 60°and 90° increased to different extents compared with that before autotraction. There was signifi- cant difference （P〈0.05）. The width of each lumbar intervertebral space after autotraction with the angle of 60° changed a little compared with that after autotraction with the angle of 90°（P〉0.05）.Conclusion：Autotraction with the angle of 60° and 90° increase the lumbar intervertebral space and there is no significant elevation of BP and pulse. There is no significant difference of the therapeutic effects between autotraction with two angles.
