伸颈

The displacement pick-up was put into C3/4 intervertebral space and axis pressure (0～160N) homolateral-bending (0～1.5Nm), oppositeside-bending (0～1.5Nm), back-extending (0～1.5Nm) and anteflexion (0～1.5Nm) were respectively loaded. After having measured the morphological changes of C3/4 intervertebral foramena in C5/6 intergrity group, discectomy group and replaced group, the changes in different groups were compared.

将位移传感器置入C3/4椎间孔内，在颈椎标本上施加轴向（0～160N）、同侧弯（0～1.5Nm）、对侧弯（0～1.5Nm）、后伸（0～1.5Nm）、前屈（0～1.5Nm）分级载荷，分别测量C5/6椎间盘完整组、C5/6椎间盘髓核摘除组和C5/6人工颈椎间盘置换组，C3/4椎间孔高度、宽度和ROV。

METHODS: 240 cases suffering CSA were selected and divided into groups according to anatomy angle of lesion parts (upper cervical segments, lower cervical segments, mixed type) and traction mode, angel (anteversion sitting position 1°-10°, 11°-20°, 21°-30° groups, posterior extension sitting position 1°-10°, 11°-20°, 21°-30° groups, neutral position sitting position group). Local massage served as control group.

选择椎动脉型颈椎病患者240例，根据解剖学角度按病变部位(上颈段病变、下颈段病变、混合型)和牵引方式、角度(坐位前倾分1°~10°、11°~20°、21°~30°组，坐位后伸1°~10°、11°~20°、21°~30°组，坐位中立位组)分组，以局部按摩为对照组。

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。

This is the most widely used approach to crane modeling.

这是伸颈模型的最广泛二手的方法。

Extensor hypertonia, neck stretched back, lower extremity stretching or cross, his hands can not get in front of the middle bit, showing the anti-bow angle of trunk extension Zhang.

仰卧位伸肌张力增高，颈向后伸，下肢伸或交叉，双手拿不到前方正中位，呈角弓反张性躯干伸展。

Group C, based on the protocol of group A, double-door laminoplasty with reconstruction of posterior cervical ligamentous complex was performed.

新鲜山羊颈椎标本24具，随机分成3组，每组8具。A组，完整标本组，保留后方项韧带、伸肌等伸颈结构，切除前方结构；B组，在A组基础上行重建颈后方韧带复合体单开门椎板成形手术；C组，在A组基础上行重建颈后方韧带复合体双开门椎板成形术。

With taxi drivers as subjects, Experiment Three investigated the comfort at dynamic driving situation by the eEMG tests of neck extensors, erector spinae muscle, multifidus muscle and biceps femoris muscle through maximum back expansion and Biering-Sorensen Testing.

实验三借助sEMG技术对出租车司机进行驾驶试验，通过对颈伸肌、竖脊肌、多裂肌、股二头肌的sEMG测量，对最大背伸肌力和耐力负荷进行了研究，考察了驾驶员在动态驾驶情况下的舒适度。

The hoop tension force is axisymmetrical about the tension direction and increase from the top position to both sides. The distribution of hoop tension force is even with small friction coefficient, but will increase rapidly from top to side positions, which subsequently result in necking and fracture near the edge of gauge section.

结果表明：采用正压力线性变化假设所得的切向力分布规律与拉伸实验结果吻合较好；切向力关于拉伸方向呈轴对称分布，从正上方到两侧逐渐增大；当摩擦系数较小时，切向力分布较均匀，但当摩擦系数较大时，切向力从正上方到两侧迅速增大，试样的颈缩和断裂发生在标距段内靠近标距边缘的位置。

A contracted state of the neck muscles producing an unnatural position of the head.

假如这是有益于罗马人民的。一边说着一边伸颈就死。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
