Results During 20° flexion to 15° extension, average relative angles at the adjacent levels of C6–7 and C4–5 in the fused patients were 13.4° and 8.8° versus 3.7° and 4.8° in the healthy individuals.

结果 在屈20°伸 15°，，对C6-7与C4-5的相邻节段测其平均角度，。在融合病人为13.4°与8.8°，而在健康人群为3.7°与 4.8°。

Each of eight adult fresh cadaver specimen of lumbarsacral segmcnts was analyzed in four states: intact, L5S1 ALIF, L5S1 ALIF fixed with pedicle screw or fixed with translaminar facets screw, test and compare its range of motion in flexion, extension, lateral bending and axial rotation.

方法］ 采用新鲜腰椎标本8具，分别于完整状态、L5S1，前路植以Cage、L5S1，前路Cage分别行椎弓根钉固定及经椎板关节突螺钉固定下，测定前屈、后伸、侧弯及扭转运动下运动范围并进行比较。

Recommended threshold criteria for solid fusion using flexion-extension radiographs have varied from 0 to 5 of angular motion between vertebrae.

概括背景资料：我们推荐评判融合是否稳定的标准是：在腰椎过伸过屈位片上，椎间的矢状面活动角度不超过5度。

Methods Seven cadaveric spinal specimens were measured of neutrol zoneand range of motionin 6 movements including anteflexion,retroflexion,left and right lateral flexion,left and right axial rotation.

测试前屈、后伸、左侧弯、右侧弯、左旋转、右旋转的中性区(neutral zone，NZ)和运动范围(range of motion，ROM)。程序：完整状态；②骨折后状态；③椎体成形后；④3000次循环疲劳后。结果骨折后中性区和运动范围均明显增大。椎体成形后屈伸、侧弯、旋转在NZ及ROM均明显减少。

Our findings indicate that tibiofemoral AP translation during knee flexion can be assessed on an active flexion lateral knee radiograph and provide additional information that is not available from a routine lateral radiograph.

我们的研究结果表明膝关节屈曲时胫骨和股骨之间在前后位上的移位能够在主动膝关节屈曲侧位 X 线片上进行评估，并且和既往常规侧位片相比，我们又提供了新的信息，这些信息是既往常规 X 线片所不能反映出来的。

In an effort to obtain a quantitative measurement of both anteroposterior tibiofemoral position and active knee flexion we have routinely taken post-operative lateral radiographs in a position of maximal active flexion.

为了定量测量出前后位胫骨与股骨之间的相对位置及主动膝关节屈曲范围，我们常规在术后拍摄了最大主动屈曲状态时侧位 X 线片。

The length of the anterior bundle was maxium at 90° of the elbow flexion, the length of the posterior bundle varied with the change of the angle of elbow flexion, and a transverse bundle was unchanged.

前束在肘关节屈曲90°时最长，此时亦为最紧张状态，后束则随肘关节屈曲角度增大而逐渐变长，而斜束的长度不随肘关节屈曲角度的变化而变化。

The results indicate that weight factor had significantly effect on gait speed, steps per minute, gait cycle time, the ratio of stance time and swing time, maximal flexion angle of knee joint and the range of motion of elbow joint. Shelf height had significantly effects on hip flexion and elbow ROM. Box size factor had significantly effect on stride length, gait cycle time, the ratio of stance time and swing time, knee joint elbow ROM. For the muscle activity levels with EMG, load weight and shelf height both affected the %MVC significantly. When the subjects carrying a load of 14kg, the muscle activity and the subjective body part discomfort rating are both higher than that of 7kg. The box size had effect on the body part discomfort rating of upper extremity and back. For the kinetic and kinematics analysis, the shelf height around elbow height was better than the other two height levels.

研究结果显示，对步态时间与空间参数而言，重量因子显著影响步速、步频、步态周期时间与站立期摆荡期比值，箱型因子显著影响步长、步态周期时间与站立期摆荡期比值；关节活动度而言，重量显著影响膝关节最大弯曲角度、肘关节屈伸角度范围，高度因子显著影响髋关节前后倾角度、肘关节活动各变项，箱型因子影响膝关节弯曲最大最小值以及肘关节活动各变项，对肌肉活动度而言，重量与高度因子皆显著影响MVC%值，14公斤重者肌肉活动度与主观不舒适程度皆较7公斤者高，箱型因子虽无明显影响肌肉活动度，但是在主观不舒适程度上却明显影响上肢与背部，终点放置高度应设在肘高附近为佳。

To investigate the the body shape strength and kinematics thateffects sprint expert performance 17 healthy male sprinters weremeasured using SongxiaM9000 high speed vidicon in the field; body shape of sprint athlete were tested by steel rule; Meanwhile shoulder were tested at 60, 240and360 deg/sec velocities ; lower limb were tested at 60, 240 deg/sec velocitues using Biodex-II tesing and rehabilitation system in the laboratory This research provide theoretical basement to scientifically make reasonable exercise prescription and perfect sprint theoryThe result show that (1) The results of correlation indicate that 100M performance related to the shoulder fast flexion torque and hip flexion/extension torque^ ankle fast dorsiflexion torque ;(2) The upper arm relaxing enclose and lower limbs length effect 100Mperformance;(3) The biggest shoulder extension joint, swing rage of shoulder and the biggest elbow joint extension effect 100M performance.
