自体倒立牵引对正常人腰椎长度的影响

目的观察不同角度自体倒立牵引对正常人腰椎长度的影响。方法采用自体重量牵引方式,对20名健康军校学员进行脊柱牵引,测量不同角度（-15°、-30°、-45°）牵引时的腰椎长度、脉搏和血压。结果三种角度牵引后与牵引前比较,腰椎长度均有不同程度增加。但-15°牵引与牵引前相比,差异无统计学意义（P〉0.05）;而-30°和-45°牵引与牵引前相比,差异均有统计学意义（均P〈0.05）,但两种角度牵引之间相比腰椎长度变化差异无统计学意义（P〉0.05）。采用本方式牵引对收缩压和脉搏影响较小,但是可以引起舒张压的升高。结论 -30°和-45°自体倒立牵引均可以使腰椎长度明显增加,且两者之间差异无统计学意义,但是由于会引起舒张压的轻度升高,故该方式牵引对高血压、心脑血管疾病患者应当慎用。

Effect of inverted traction on the length of normal lumbar spine

Objective To observe the effect of inverted traction on the length of normal lumbar spine from different angles.Methods Twenty healthy students were towed by self-gravity.The length of lumbar spine,pulse and blood pressure were measured from different angles（-15°,-30°and-45°）.Results The length of lumbar spine increased in varying degrees after inverted traction with the three angles.No statistical differences were found between inverted traction with the angle of-15° and before traction（P0.05）.The length of lumbar spine was significant difference（P0.05） between inverted traction with the angle of-30°,with the angle of-45° and before traction.There was no significant difference of length increased between two angles（P0.05）.Conclusion Inverted traction with the angle of-30° and-45° increase the length of lumbar spine and there is no statistical significance between inverted traction with the two angles.But this way should be careful for the patients who suffer from hypertension,cardiovascular and cerebrovascular diseases,because it can slightly increase diastolic pressure.
