With the development of industry, musculoskeletal disorders have become increasingly prominent, and low back pain is one of the major problems. The United States and Germany have already included it in the category of occupational diseases. Therefore, it is extremely important to determine the occupational factors affecting low back pain and evaluate the load level of workers. In this paper, combined with the existing literature, the evaluation methods of the load of low back pain were reviewed, in order to provide reference for the development of prevention strategies of low back pain from the perspective of occupational factors.
