Four categories cause of lower back pain
It can cause low back pain of many causes, but work-related lower back pain often associated with the following factors:
Causality heavy physical load between physical load and low back pain was almost accepted by all researchers.
Poor working posture to bend or twist the body will increase the pressure on the spine and cause uneven force the spine, it is a major risk factor for low back pain.
Studies have shown that whole-body vibration and lower back pain Chinese motorists prevalence of 57% -82%, slightly higher than the level of foreign workers in the same industry; in addition to this one for a long time sitting, smoking, fatigue and other relevant outside vibrations also an important factor causing low back pain.
Psychological factors engaged in labor intensive work, the work requires high concentration of attention, long working hours, work content monotonous repetition, and poor working conditions are unfavorable factors for the occurrence of occupational low back pain play a catalytic role.
Lower back pain is work related diseases
Lower back pain is a common type of work-related illness, the US, Germany, Japan and the Nordic countries have been included in the occupational low back pain need to compensate list of diseases.

Since many risk factors of back pain, its pathogenesis is very complex. Epidemiological findings suggest that lower back pain and a long fixed working posture, heavy physical labor and other factors have a significant correlation. In general, the work can be divided into static and dynamic job job categories. Static operation due to the fixed body posture, body posture to maintain the strength of fall entirely on the relevant muscles, the ligaments, the ligament tension for a long time, affecting blood circulation and nutrition, the results can lead to chronic musculoskeletal injuries. When dynamic job by force and frequent muscle, ligament fiber breakage may occur small, bleeding, exudation, resulting in the formation of scar tissue and adhesions, thus traction and compression of the nerve, resulting in pain.
Occupational low back pain mainly for persistent low back muscle pain, a long time in the same posture will aggravate the symptoms, postural adjustments can be alleviated, treatment, generally about one week of rest and timely recovery, low back pain, otherwise time will be extended, and even cause radioactive buttocks, leg pain, disc herniation or even severe, lower extremity muscle strength severely affected.
