Study Design: A multifactorial cross-sectional nonexperimental design. Objectives: To collectively investigate the association among 17 mechanical factors and occurrence of low back pain (LBP). Background: Several physical characteristics, based on assumptions, clinical findings, and scientific experiments, have been associated with the development of LBP. Controversy exists regarding the degree of association between some of these physical characteristics and LBP. Information regarding the degree of association of each factor to LBP is needed for effective prevention and appropriate treatment strategies.
