前屈

The stability was compared by measuring the destructive torsional moment and angle rotation as well as destructive flectural loading and displacement.

颈椎严重损伤在选用内固定后，由于抗旋转和前屈强度及位移差异，可适当辅以外固定。

Uncomfortable symptoms including dizziness, dim eyesight, cardiopalmus, acratia will appear when seated for a long time because of cerebral blood flow reduced for the reason of cervical vessels flexure or compressed, which result in lack of oxygen and nutritive materials.

由于久坐头处于前屈位，颈部血管轻度屈曲或受压，会使流向脑部的血流受到限制，脑血流量减少，从而造成大脑的氧和营养物质供应不足，出现头晕、眼花、心悸、乏力、手足麻木等不适症状。

Objective To study the effect of the rotation manipulation on degenerate lumbar disc in three anteflexed levels.

目的 探讨不同前屈状态下坐位腰椎旋转手法对椎间盘的影响。

You should take care not to hyperextend your knees in Trikonasana, just as in Tadasana and Uttanasana.

你应该注意在三角式中不要膝关节超伸，就像是在山式和站立体前屈一样。

Extension view. Intravertebral gas becomes apparent in L5 body.

前屈位。后伸位，L5椎体可见真空现象。

No significant difference were found between left and right hand weight loading for erector spinae during the trunk movements, but the values of AEMG with back weight loading were significantly higher than left and right hand weight loading;(2)The AEMG of lumbar multifidus had no significantly different under three load ways during the walking.

(1) 躯干屈曲伸展过程中，腰部多裂肌与竖脊肌各自两侧的激活程度呈现对称性特点；躯干伸展运动对腰部竖脊肌和多裂肌的激活程度大于屈曲运动；(2)腰部多裂肌在躯干旋转时激活特征存在显著的对侧增强效应；(3)腰部前屈过程中，竖脊肌和多裂肌肌肉的高激活区域可能集中在45°—65°的角度范围之内。

The general displacement of centrums was observed after the traction in each patient.

结果：前屈10°位牵引椎体后缘分离较前缘明显，中立位牵引椎间距离增大最明显。

Results: The posterior margin separation of centrums was more obvious than anterior margin separation in cases with traction from anteflection position of 10 degrees, while the most increases of intervertebral space occurred in cases with traction from neutral position.

颈椎牵引在中立位时对椎间盘的轴向作用最大，前屈位时受力集中在椎体后缘，后伸位转移到后侧小关节。

In the later stages of pregnancy, extreme forward bends are contraindicated

另外，针对怀孕后期的准妈妈们，过度的前屈也是不适当的。

A pulled hamstring is a common muscle strain seen in yoga class. This occurs particularly where the hamstring attaches to the sitting bones, and is a result of overstretching in seated forward-bending poses.

腘绳肌的拉伤是瑜伽中的常见损伤，尤其发生在腘绳肌与坐骨联结处，也可由于坐立前屈体式中的过度拉伸。

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。
