Though research exists that links LBP to specific factors, studying risk factor effects in isolation of other effects fails to quantify interactive effects of risk factors on LBP (Marras, 2005).
From the literature available it is evident that many identified risk factors across categories are not mutually exclusive and interaction effects also need to be studied to fully explain the incidence of low back pain (Marras, 2005).
Further research is required to study interactions of the various personal, psychosocial and occupational factors and their effects on low back pain in order to identify a combination of factors that may increase injury risk.
