Simulate the lumbar spine front flexion, back extension, and left / right lateral bending movement in the three-dimensional laser scanner, and the rotation motion in the vertical axis in the mechanical properties of biological materials tester. 在三维激光扫描仪上模拟腰椎的前屈后伸、左右侧弯运动,在生物材料力学特性试验仪上模拟腰椎在纵轴上的旋转运动。
The ranges of coupled axial rotational motion of flexion, extension, left lateral bending, and right lateral bending were, 12.42,16.14, 22.07 and 22.48 degrees respectively. 寰枢关节屈曲,后伸,左右侧屈主运动时伴有明显耦合旋转运动,其范围分别是12.42°,16.14°,22.07°,22.48°。
