动关节

Methods. A 60-year-old man with athetoid cerebral palsy and a history of posterior occipitocerical fusion presented with quadriparesis. Salage surgery for cerical myelopathy and pseudarthrosis was performed with laminectomy and rearthrodesis using the pedicle screw system. An intraspinal cyst was identified as the main cause of the paraparesis.

一位60岁的手足徐动症样大脑麻痹患者，既往曾行后路枕颈融合术，临床表现为四肢轻瘫，影像学检查示脊髓型颈椎病和假关节形成，采用椎板切除和椎弓根钉系统关节成形术后，发现椎管内存在的囊肿是导致四肢轻瘫的主要原因。

By using the Lagrangian approach, the explicit dynamic model in the Cartesian space and joint space is created. The model has taken full account of the influences of the length variation of the driving links and the orientation of the translational mechanism.

其次，本文应用拉格朗日方法首次系统地建立了该并联机器人在操作空间和关节空间的显式动力学模型，该模型充分考虑驱动杆长度变化和平动机构位姿变化对操作力的影响。

He was sounding the deeps of his nature, and of the parts of his nature that were deeper than he, going back into the womb of Time. He was mastered by the sheer surging of life, the tidal wave of being, the perfect joy of each separate muscle, joint, and sinew in that it was everything that was not death, that it was aglow and rampant, expressing itself in movement, flying exultantly under the stars and over the face of dead matter that did not move.

这声音发自他天性深处，发自那比他自身更深远的天性，回溯到纪元的初始，生命的涌动、存在的奔腾、全身健全的肌腱关节的畅快控制了他，那产生于一种难以明状的东西，既狂热又暴烈，体现为在星空之下，在静止不动的死物表面上的欢快飞驰。

Imitated the characteristics of gymnast's swing-up and handstand movement,the control process of robot is divided by six sequence phase.

在完成这些动作的过程中，身体各关节力的大小和方向的协调控制具有高度的技巧和动觉智能。

The bone s must be returned to their normal position and the joint kept immobile until healed.

骨头必须回到其正常的位置，然后保持关节固定不动到完全愈合。

While the idea and the prototype of the three-degree-of-freedom motor came into being, it is more convenient to realize the motion of the robot joint where the demand on workspace is low but three DOF is required. It also combines the merits of simplified system construction, minimized machine volume, improved dynamic and static performance with high position accuracy.

三自由度球形电机设计概念及样机的出现，使得机器人关节的空间三维运动可以在一个较小的工作空间中完成，简化了系统结构，减小了机构体积，有利于提高系统的动、静态性能和定位精度。

researches on kinesthesia in sports mainly include such areas as the effects of kinesthetic or visual information on the formation of sports skills, movement orientation accuracy, and articular kinesthesia, having such problems as neglecting the exploration of connotations of kinesthesia theories and failing to make the study according to the characteristics of sports events.

体育运动中的动觉研究主要集中在动觉或视觉信息对运动技能形成的影响，动作方位准确性，关节动觉感受性等方面。现有的研究存在忽视对动觉理论内涵的探讨，未能根据运动项目的特点进行研究等问题。

Elderly patients with conservative treatment of femoral neck fracture in the bone unhealing rate, avascular necrosis rate and bed incidence of complications are very high, often need surgical treatment, Currently Artificial arthroplasty better able to load the early running, and significantly improved the quality of life. Orthopedist has been universally acknowledged, which was also hemiarthroplasty for and hip arthroplasty mainly, But these indications of operation and the pros and cons of surviving in numerous disputes, By comparing our double-action Hemiarthroplasty with total hip arthroplasty for femoral neck fracture in the elderly average operative time, The average blood transfusion, the average length of stay, average hospital charges, early complications, Harris score, Oxford hip score standards evaluation discussion bipola Femeral Head placement with total hip arthroplasty in the treatment of femoral neck fracture in the elderly: the advantages and disadvantages.

老年患者股骨颈骨折保守治疗的骨不愈合率、股骨头缺血坏死率及卧床并发症发生率很高，常需要行手术治疗，目前应用人工关节置换疗效较好，能早期负重行走，生活质量明显提高，已得到骨科医师的普遍认同，其中又以人工股骨头置换术和人工髋关节置换术为主，但这些术式的适应证及利弊尚存在诸多争议，我们通过比较双动人工股骨头置换与全髋关节置换治疗老年人股骨颈骨折的平均手术时间、平均输血量、平均住院时间、平均住院费用、早期并发症、Harris评分、牛津髋关节评分标准评价来探讨双动人工股骨头置换与全髋关节置换在老年人股骨颈骨折治疗中的优势与劣势。

此时关节保持平衡点不动，关节总力矩为0，但有一定的刚度。

My children will all have spavins and heaves.' Well, Ma fainted when I said that about spavins, but I stood firm and Grandma backed me up.

我的孩子会像马那样得大关节病和气喘病的'好，我妈一听说大关节病便晕倒了，可我巍然不动，我奶奶也支持我。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.
