脊柱形态测量仪(Spinalmouse)测评腰痛患者全脊柱运动能力

目的量化测量脊柱各个椎体椎间角度变化，评估腰痛患者全脊柱运动能力。方法使用脊柱动态测量仪（Spimalmouse）测量34例腰痛患者不同姿势下的脊柱形态，得出量化脊柱各个椎体之间椎间角角度，并摄腰段X线片并测量，所得数据间进行独立样本t检验和配对样本t检验。结果直立位胸腰椎各个节段之间椎间角度基本符合脊柱生理曲线，前屈时T1－7，没有椎间角度变化差异，T8以下差异均有统计学意义（P〈0．05）。后伸时T6-8，T12、L1，L2，3这4个节段椎间角变化差异均有统计学意义（P〈0．05）。在与X线片对比时，T11～L3的各个椎间角度的结果是与影像学资料测量的角度数据基本一致的，差异无统计学意义，但在L3～S1，测量结果差异有统计学意义（P〈0．05）.结论Spinalmouse可以直接、方便地测量出胸、腰椎各个椎间角变化，并且存在很好的可靠性、重复性和可信性，是脊柱各个节段运动能力评定的良好工具，且避免了X线辐射。

Spinal mobility of low back pain patients measured by the Spinalmouse

Objective To measure spinal intervertebral angles in order to value the spinal mobility function of the low back pain patients. Methods All the 34 low back pain patients were measured by Spinalmouse and X-rays in different positions. Each spinal intervertebral angle was calculated in different groups by t test (independent or paired). Results The spinal intervertebral angles were fit to the normal spinal physiological curve. When flexion, the spinal curve at T_1~7 level changed little, while T₈-S₁ changed significianly (P<0.05). While extension, the most changes happened at T_6-8, T₁₂-L₁,L_2,3 segments (P<0.05). To compare with X-rays, T₁₁-L₃ were no significant different changes while L₃-S₁ had significant difference (P<0.05). Conclusion Spinalmouse can measure spinal intervertebral angles directly and conveniently. It is a good instrument to value the spinal mobility function with good reliability, repetitiveness and creditability and without any X-ray radiation.
