下肢

In 47 cases with ABI〈0.9, 40 patients were suffered with lower limb vascular diseases.

其中，ABI〈0.9的47例中40例下肢血管彩超示有下肢血管病变。

The recovery of the hemiplegic upper limb diose not only involve the motional function,but,because of the speciality of its functional impairments,also involves the psychologic problem which mainly includes the slower recovery of he hemiplegic upper limb than the lower one,agnosia,apraxia and shoulder-hand syndrone.

因 在运动方式上，上肢要承担复杂、精细、灵巧的动作，而下肢只是完成简单、粗、半自动的步行，只要维持躯干平衡就能在地面走路[1]。这并不是说下肢的康复治疗不重要，只是说明上肢的康复治疗复杂、更精细，在康复治疗过程中，不仅存在运动功能问题，而且还涉及心理问题。

To study the regular human gaits,the test system based on string displacement sensor and human joint angle measurement instrument are used to measure the motion trajectory of anklebone and the joint angles of lower limb under walking in different road conditions,and the measurement data is analyzed and treated based on human rigidbody model and with data fusion method.Then the gaittrajectories and standphases are gotten under the condition of upstairs,normal walking and downstairs.The result shows that the longest standphase is in upstairs condition,the middle is normal walking and the shortest is downstairs.

为研究人体的步态运动规律，采用基于拉线传感器检测系统和人体关节角度测量装置，对人在不同路况下行走时踝关节运动轨迹和下肢关节角度进行了测量，根据人体下肢刚体模型和数据融合方法对测量结果进行了分析和处理，得到了人在上楼梯、平地行走和下楼梯时的步态轨迹和3种路况下的支撑相；上楼梯时的支撑相最大，平地行走次之，下楼梯最小。

This study was to observe the result in patients suffering from severe ischemia of legs with arterialization of the great saphenous vein. Eighty nine patients suffering from the disease were treated by bridging the autogenous cephalic vein or Gore-Tex artificial vessel between the great saphenous vein and the femoral or external iliac arteries.

摘 要 为探索一期大隐静脉动脉化治疗下肢严重缺血症的效果，采用自体头静脉或Gore-tex人造血管，在大隐静脉与患肢股动脉或髂外动脉之间搭桥，治疗89例127侧下肢严重缺血症患者。

Objective To discuss the application value of 16-slice spiral CT in lower extremity angiography diagnosis of arteriosclerotic occlusive disease.

目的：探讨16层螺旋CT下肢血管成像技术诊断下肢动脉硬化性闭塞症的应用价值。

Although there were the legs fluid distribution augmentative phenomenon, the sport behavioral （the ability of standing with eye closed and the ability of vertical jump） was still better.

有关液体改变情况和下肢水分分布增加的结果提示在今后同类训练科目中应注意适当补充水分和电解质、采取早期干预的措施，有效地防止下肢肿胀现象。

(1) The input of the internal fixation implant should be in accordance with the compressive trabeculae and be clingy with the femoral calcar, Abduction in small degree (10-30°) will improve the stress in femoral neck region. The stress distribution of the femur under extemal violence explained why the old people are easy to get the middle and low part fractures of the femoral neck and intertrochanteric fractures.(2) The finite element model of femoral neck fracture is good in orrowing various fixation methods for femoral neck fracture.

(1)三维有限元方法用于研究不规则物体是一种有效、准确的数值方法，不仅能考虑到所研究物体的几何形状，而且也考虑到物体的内部结构特性；股骨颈处的压力骨小梁和股骨距是重要的承载结构，内固定物的放置应循压力骨小梁方向尽量紧贴股骨距钻入；载荷主要通过压力骨小梁和股骨距传导至股骨干的中下1/3处；一定角度的下肢外展（10-30°）会较明显的增加股骨颈区的应力，而下肢的内收反而会减小此区的应力；暴力作用时股骨上端应力分布特点从生物力学角度说明老年人易于发生股骨颈中下段骨折和转子间骨折的原因。

The center of pressure displacement in the lace-up group is bigger than other two groups.

四、赤足组其著地期下肢长度变化量显著大於Lace-up组（P＜。05），且Lace-up组其著地期下肢劲度和踝关节劲度皆大於赤足组（P＜。05）。

Two rehabilitation physicians used the MAS to assess the muscle tone of the elbow flexors,wrist flexors,quadriceps femoris,hamstrings,hip adductors,gastrocnemius and soleus in...

结果：被评估的患者上肢肌肉以及膝屈和伸肌的信度较高(0.582～0.832)，而下肢比目鱼肌和腓肠肌的信度较低(0.095～0.486)。结论：MAS用于评定下肢肌特别是下肢远端肌群时应慎重。

To reduce risk of driver lower extremity injury in frontal impact, on the basis of literature studying about the well-adopted research method and fundamental theory, the paper summarized the experience and results obtained in the field of driver lower extremity injury research.

为了降低前碰撞中驾驶员下肢的损伤风险，本文通过对下肢损伤已采用的研究方法和基础理论的文献研究，深入了解并总结了下肢损伤研究领域所取得的经验和成果。
