旋转关节

A new analytic scheme for solving the inverse kinematics equations of CRS robot manipulator was presented by the shift of the joint coordinates and the rotation coordinate system, which were significant to optimize the robot motion and path planning, and the formulas of calculating the sine and cosine of each rotate angle variable were solved.

通过关节坐标的转换和旋转坐标系统的引入，给出了CRS机械手逆运动方程求解的一种新解析法，直接推导出各个关节转角变量的反三角公式，为机械手的运动优化和轨迹规划创造了条件。

Results of measurement of mimic rotatory manipulative reduction indicate that there are undulant changes within the intra -pressure of posterior facet joints.

对模拟旋转手法测定表明：后关节内压力呈波浪状变化，其下关节突出现向上→前→下→后的全方位移动。

All case of illness all are traumatic send radius far end 3 months after fracture issues dislocation of feet oar joint to treat come 1 year patient, all have wrist ministry ache, wrist ministry is faint, antebrachium whirligig suffers bounds symptom, via X line photograph examination diagnose is dislocation of joint of oar issueing rule. Below anaesthesia of sluggish of block of nerve of clump of arm of 1.2 operations method, the upper arm having side uses hemostatic tape.

所有病例均为外伤致桡骨远端骨折并下尺桡关节脱位治疗后3个月至1年患者，均有腕部疼痛，腕部无力，前臂旋转运动受限的症状，经X线照片检查确诊为下尺桡关节脱位。1.2手术方法臂丛神经阻滞麻醉下，患侧上臂应用止血带。

Flexible pneumatic torsion joint is another application of FPA. A torsion joint is mainly composed of two arcual FPAs, which can realize turning movement in a plane.

气动柔性扭转关节是FPA的另一个应用，扭转关节主要由两个弧形的FPA构成，可以在平面内形成旋转运动。

Methods: 12 fresh frozen adult leg-foot specimens were mounted in a coordinated system, a Steinmann pin was perforated across the calcaneus, cuboidcum, talus, and naviculare as markers. The displacements of the marked points in the coordinated system were recorded. Through matrix translation and Euler equation, the rotational angle of the calcaneus, cuboideum, talus, naviculare were calculated, which represented the motion of the calcaneocuboid, talonavicular and ankle joint in different condition respectively, while statistical analysis were also taken between different conditions.

取新鲜足标本12例，通过加载使足产生某种形式的运动，用三维数字化坐标仪测量距下关节组成骨在某种运动状态下的相对三维坐标位移，通过矩阵转换和求解非线性函数方程计算其三维旋转角度，确定距下关节的运动范围、规律和在足整体运动中的作用。

The huge interarticular contact force of artificial atlanto-odontoid joint at shear and flexion/extension will bring about abrasion, mobilization and destruction of bone or prosthesis. There is potential instability in rotation after replacement operation.

人工寰齿关节置换术后前后向剪切和屈伸运动时人工寰齿关节间的接触应力过大，易造成磨损、引起假体松动和骨或假体的破坏；并且潜在旋转不稳的趋势。

Results: The scaphoid and lunate primarily flexed or extended in all directions of wrist motion, and their rotation aried linearly with the direction of wrist motion (R2 = 0.90 and 0.82, respectiely).

结果：舟状骨和月骨在腕关节各个方向上原始的屈曲和背伸及旋转运动与腕关节运动呈线性关系（分别为R2 = 0.90 和0.82）。

The dorsal radiocarpal ligament was the most strongest of all wrist ligaments,and radiolunate ligament was the most strongest of palm radiocarpal ligaments.

三维运动分析：挠骨远端关节面出现一10以上变化时，挠腕关节运动主要是掌屈、尺偏及前臂旋转运动范围受限。

These can then be parented under a Maya joint such that the tendon surface will bend as the joints rotate.

然后parent到maya关节下，筋就会随着关节旋转弯曲。

The ROM of L5-S1 segment was significantly increased in flexion, left and right lateral bendings (relative ROM 1. 57, 1. 43, 1. 61 seperatively).

双侧小关节内侧1/2切除和双侧小关节全切除状态之间在右轴向旋转运动方面有显著性差异。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
