前屈

M moments was loaded to simulate lumbar axial compression, anteflexion, extension, lateral bending and rotation. The stress of the pedicle screws was recorded.

m的力矩模拟腰椎前屈、后伸、侧屈和旋转等各种生理载荷，观察不同载荷下螺钉的应力分布。

The patients were treated with routine manipulation(group A,30 cases) and PMWL(group B,30 cases) respectively.The difference pain,function,range of active anteflexion,anteflexion strength and satisfaction degree of patient were analyzed according to UCLA scoring system after one period of treatment score.

分为2组，分别采用常规治疗和杠杆扳法治疗，每组30例，在治疗1个疗程(10次)后利用UCLA进行功能评分，比较两种治疗方法在疼痛、功能、主动前屈活动、前屈肌力及患者满意度方面的差异。

MAIN OUTCOME MEASURES: Stress images and peak stress of pedicle screws under lumbar axial compression, anteflexion, extension, lateral bending and rotation.

主要观察指标：椎弓根螺钉在轴向压缩、前屈、后伸、侧屈和旋转等各种生理载荷下的应力云图和峰值。

The difference pain,function,range of active anteflexion,anteflexion strength and satisfaction degree of patient were analyzed according to UCLA scoring system after one period of treatment score.Results:The pain,function and satisfaction degree of patient after treatment got better than those before treatment in group A(P.05);the active range and anteflexion strength had no improvement.

分为2组，分别采用常规治疗和杠杆扳法治疗，每组30例，在治疗1个疗程(10次)后利用UCLA进行功能评分，比较两种治疗方法在疼痛、功能、主动前屈活动、前屈肌力及患者满意度方面的差异。

RESULTS:In vertebral pulp extirpation group, the stress was proved to be the highest at superior edge, posterior middle part, lower edge and anterior middle part of small joints under anteflexion, backward extension, compression, lateroflexion and revolving states, moreover, small joint stress in artificial lumbar intervertebral disk was higher than that in normal intervertebral disk, but obviously lower than that in vertebral pulp extirpation group;however, the small joint of the middle part of artificial lumbar intervertebral disk bore the highest stress under revolving states.

结果：髓核摘除组小关节的上边缘部、后中部、下边缘部和前中部在前屈、后伸、压缩、侧屈、旋转状态应力最大，人工腰椎间盘组的小关节的应力比正常椎间盘高，但明显小于髓核摘除组，但正中部在旋转状态下，人工腰椎间盘小关节的中心部位承受的应力最大。

The therapeutic efficacy in posterior extension sitting position occupying 11-20° was better in upper hind neck; the therapeutic efficacy in anteversion sitting position occupying 11-20° was better in inferior neck; the therapeutic efficacy in anteversion sitting position occupying 1-10° was better in neutral position sitting position.

即上颈段椎动脉型颈椎病患者坐位后伸11°~20°牵引疗效较好，下颈段椎动脉型颈椎病患者坐位前屈11°~20°牵引疗效较好，混合型椎动脉型颈椎病患者坐位前屈1°~10°疗效较好。

The splenius capitis muscle was found to be significantly different for flexion, left anterolateral flexion, and left lateral flexion.

头颈夹肌在前屈、左前侧屈、左侧屈时具有显著的差异。

The parameter of mechanics was analyzed with the finite element system in three anteflexed levels:6°, 9° and 12°. Results The stress and displacement of the right side of lumbar disc were increased gradually during the manipulation.

结果 ①对于正常腰椎，椎间盘左侧后缘的应力随着腰椎前屈角度增大而增大，前屈角度的变化对位移的影响相对较小，椎间盘无明显向后突出。

Midwifery were quickly placed palace at the bottom with one hand, thumb in the anterior, posterior wall of the remaining four means for Palace at the end of even a massage by massage the uterus starts to contract, can be placed in the vagina before the one hand fist fornix, to withstand the uterus anterior abdominal wall push the other hand since the back wall of the uterus, so that the uterus flexion, the relative pressed his hands to massage the uterus.

助产者迅速用一手置于宫底部，拇指在前壁，其余4指在后壁，作均匀有按摩宫底，经按摩后子宫开始收缩，亦可一手握拳置于阴道前穹窿，顶住子宫前壁，另一手自腹壁按压子宫后壁，使子宫体前屈，两手相对紧压子宫并作按摩。

In all flexion activities, symmetrical or asymmetrical sternocleidomastoids were the major flexor muscles, and they had to balance the mechanics of the neck as agonists, synergists, or antagonists.

在所有的前屈肌中，对称性的和不对称的胸锁乳突肌是主要的前屈肌，并且，他们在颈椎的运动中，承担着主动肌、平衡肌和拮抗肌的作用。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
