脊柱动态测量仪对正常人和腰痛患者脊柱运动能力的量化测量

目的：量化测量脊柱各个椎体椎间角度变化,评估腰痛患者运动能力下降程度。方法：使用脊柱动态测量仪测量112例正常人和60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,并进行独立样本t检验和配对样本t检验。结果：腰痛患者脊柱前屈运动能力比正常人下降80%,后伸要比正常人要下降60%,P〈0.05。前屈时腰痛患者的胸段脊柱（T1～7）后凸增加不明显,没有显著差异,但是下胸段与腰段前凸转为后凸,椎间角度变化存在显著差异,P〈0.05。正常人的下腰段后伸能力变化最大的L4～5、L5～S1、L3～4椎间隙,在腰痛患者则表现为此3个节段的脊柱僵硬,后伸位与伸直位时椎间角比较没有显著差异。结论：脊柱动态测量仪可以直接、方便的测量出胸、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。

Spinal Mobility Sagital Range of Motion Measured with the Spinalmouse Between Normal People and Low Back pain Patients

Objective：To measure spinal vertebra angles in order to value the spinal mobility function of the low back pain patients.Methods：112 cases healthy people and 60 cases low back pain patients were measured by Spinalmouse in different positions.It was found each spinal vertebra angles and was calculated in different groups by t test（independent or paired）.Results：The spinal flexion movement of patients decreased 80% than that of normal people,while the extension movements decreased 60%.It was significantly different with P〈0.05.When flexion,the spinal curve from T1-T7 of patients changed less than lumbar spine.While extension,the most degrees of normal spine mobility range were L4-5,L5S1,L3-4.However,for patients,the three segments angles were stiff with no significant different changes.Conclusions：Spinalmouse could measure spinal vertebra angles directly and conveniently.It was a good instrument of value the spinal mobility function with good reliable,repeatable and confidence.
