How to protect the lumbar spine in daily life – lifting things to have “kind of” The action of lifting objects in daily life is common, and these routine life actions for the lumbar spine load is enough to cause injury, so in the process of lifting action we should pay attention to The following: 1, lifting objects, should make the object close to the body, which can reduce the distance from the center of gravity to the center of spinal movement (both lever resistance arm Lp) reduced, which naturally reduces the size of the lumbar spine bending moment, and ultimately the lower the load on the lumbar intervertebral disc (Figure below). Object size on the lumbar spine load (same weight, different shape) 2, in lifting heavy objects, our upper body in different postures (upright and bending) on the lumbar spine load also has a significant impact, when we bend over to lift, the weight of the object itself plus the weight of the upper body generated by the total bending moment (192.5Nm) is significantly greater than the value of the upright holding (69Nm), and similarly bending over Hold the object than upright hold the object on the lumbar spine load is also greater (the following chart). Therefore, avoid bending over to lift objects. The effect of upper body upright and bending posture lifting on the lumbar spine load 3, the study showed that when lifting objects in three ways: directly bending at the waist (192.5Nm), bending at the knee with the object close to the body (151Nm), and bending at the knee with the object in front of the knee only (212.5Nm), the load on the intervertebral disc is relatively minimal with bending at the knee with the object close to the body. In summary, it is wrong to bend at the waist and use lumbar force to extract heavy objects when lifting objects. This wrong way of lifting is the pathogenesis of many acute lumbar disc herniations and acute lumbar muscle strains and sprains, so pay particular attention to the correct lifting posture: make the object as close to the body as possible, bend the knees and back squat to lift the weight, and then stand up with leg strength. Three different ways to lift heavy objects on the lumbar spine load Tips: When we suffer from lumbar spine disease (such as disc bulge) and what should we pay attention to? Studies have shown that when lying down with good support (relaxed lumbar position), the intradiscal load is minimal, and when standing in a relaxed position, the intradiscal load is higher when sitting in a chair with no lumbar support, and the intradiscal pressure is lower if adjusted as in item 2 of this article. Therefore, when you suffer from back pain and other problems to remember, can “lying”, not sitting, standing “phase”, sitting “kind”. Lumbar spine relaxation posture
