急性腰扭伤,在体力劳动中发病率较高。发病主要原因是:因肩挑重物或提举重物时,身体用力不当,或在干活当中突然扭转身躯,以致腰部肌肉强力地收缩而造成肌肉痉挛、筋膜或肌纤维撕裂、腰骶部小关节扭挫等。常见的损伤部位为两侧腰肌,腰骶部椎间的小关节或棘上韧带等。其症状表现为腰部僵硬,运动受限,不能前屈、后仰和侧转活动,重者体位倾斜或不能行走,伤处有明显地压痛等,给劳动者带来很大的痛苦和不便。怎样防治急性腰扭伤呢?在体力劳动中思想要集中,这样才能使身体用力一致。我们千活走路都受大脑中枢神经的支配。每当人们提举重物时,大脑中枢神经就会协调地支配入的身躯和四肢去操作。如思想分散,注意力不集中就会使中枢对运动器官的支配不协调,以致脊柱平衡失调造成急性腰 Acute lumbar sprain, higher incidence of manual labor. The main reason is: heavy shoulder or lifting heavy objects, the body improper force, or in the work which suddenly turn around the body, resulting in strong contraction of the waist muscles caused by muscle spasm, fascia or muscle fiber tear, lumbosacral Small joint contusion and so on. Common parts of injury on both sides of the psoas, lumbosacral intervertebral facet joint or supraspinous ligament. The symptoms of the waist stiffness, limited movement, can not flexion, backwardness and lateral rotation activities, severe posture tilt or can not walk, the wounds were significantly tenderness, etc., to the workers brought great pain and inconvenience. How to prevent acute lumbar sprain? In the manual labor to concentrate, so as to make the body hard. We are all living under the control of the central nervous system.
