查询词典 erector spinae

The research can provide theoretical reference to ascertain work intensities of Erector spinae for forestry worker under different forestry work conditions,which has important theoretical value to quantificationally study loads and labor intensities of the lumbar muscles for the forestry workers under different forestry work conditions,to prevent and decrease the lumbar traumas,to provide laboring safety and protection,to diagnose and correct unreasonable operating postures,to train the labor skills,to design and improve forest operating tools,to prevent and treat the occupational diseases.

本研究为确定不同林业操作中劳动工人腰背部肌肉工作强度提供理论参考，为定量研究在不同林业作业中操作工人的腰背部肌肉及脊柱所承担的工作负荷以及劳动强度理论依据，并对于预防和降低林业作业工人腰部损伤、提供劳动安全与保护、诊断和矫正不良作业姿势、进行劳动技能培训、指导设计与改进林业生产工具、职业病的预防与治疗等具有重要的理论价值。

The thesis analyzed the influence of terrains and chain saws on the trunk muscles.The results showed that the terrains only influenced the Erector spinae amplitudes(p＜0.05),while it makes no sense to study the the influence of terrains on other muscles amplitudes.

在对不同地势与不同油锯对躯干各肌肉活动影响进行分析时发现，不同地势只对背部竖脊肌肌肉活动有影响(p＜0.05)，而对其他肌肉活动影响无统计学意义。

The results were showed as following:The work intensity of trunk muscles activities was different in forestry work conditions; work intensity of Erector spinae were the maximum,approaching over 30%Maximum Voluntary Contraction,and EMG amplitudes of Rectus abdominis and Oblique external abdominis were 10%MVC.

研究结果如下：在不同作业工况中，躯干不同肌肉的工作强度存在差异，背部竖脊肌工作强度为最大，均在最大用力的30%左右，其次为腹直肌与腹外斜肌均在最大用力的10%左右。

The fitting function of SEMG signal indexes and the vibration parameter change of the key parts of a human body are achieved by the regression analysis method, including the biceps brachii, erector spinae and biceps femoris. Carrying on grading to the subjective feeling, the objective method of comfort evaluation based on SEMG signals of human body under the different vibration environment is proposed.

采用回归分析法，得出了肱二头肌、竖棘肌、股二头肌的局部肌电与振动参数的拟合函数，结合主观感受评分结果，提出了振动环境下基于SEMG的判定人体舒适性的客观评价方法。

Lifting was the main component of moulding process with over 50%MVC EMG activity. The sEMG of erector spinae muscles was abnormal in moulders with low back pain during work.

造型作业中又以搬举动作肌电活动最高，超过了最大随意收缩的50％，有的搬举指数为NIOSH推荐值的4-5倍，且腰背痛的造型工人在作业期间，竖脊肌肌电活动与非腰背痛者明显不同。

STUDY DESIGN.: A prospective cohort study evaluating the quantitative lumbar flexion-relaxation phenomenon, measured with surface electromyographic signals from the erector spinae during trunk flexion pre- and postrehabilitation, in patients with chronic disabling occupational lumbar disorders. OBJECTIVES.

研究设计：评价慢性职业腰椎疾病患者量化腰椎屈曲松弛现象的前瞻性队列研究，通过测定患者康复前后躯干俯屈时竖脊肌的表面肌电信号来反映QLFRP。

Palpation reveals tenderness in the paraspinous area, with "trigger points" or "knots" in the erector spinae.

触诊时在脊柱旁有压痛，竖脊肌内有触发点或结，常发现脊柱旁肌肉痉挛，病人可向非疼痛侧轻度倾斜，活动因疼痛而受限。

Methods: 28 rabbits were divided into 3 groups (4 animals for every group). All animals were dissected to keep the spine and the pelvis, hip joint, the upper part of the femur, with the anterior and posterior longitudinal ligaments, intervertebral disk and psoas muscle, erector spinae, and supraspinal ligament attached to it.

取家兔12只，分3组，每组4只，解剖后保留枢椎以下完整之脊柱及骨盆、髋关节、上段股骨，不损伤脊柱前、后纵韧带、椎间盘及所附着之腰大肌，保留脊柱背侧的竖脊肌、棘上韧带，置于生物力学拉伸测试仪（日本岛津制作所产AGS-J系列）。

Erector spinae muscle fatigue was found after repetitively lifting and the forces at L5/S1 spinal joint were changed with various lifting technologies in volunteers simulating the lifting tasks in laboratory.

在实验室由健康人模拟造型作业中的搬举动作，结果重复搬举导致竖脊肌疲劳，而生物力学和动力学分析发现搬举姿势、搬举速度和负荷均影响脊柱腰骶关节的受力。

Palpation reveals tenderness in the paraspinous area, with "trigger points" or "knots" in the erector spinae. Spasm of the paraspinous muscles is a common finding, and the patient may have a slight list toward the nonpainful side. Motion is limited by pain.

触诊时在脊柱旁有压痛，竖脊肌内有触发点或结，常发现脊柱旁肌肉痉挛，病人可向非疼痛侧轻度倾斜，活动因疼痛而受限。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
