No link to low back pain
There is no evidence from eight systematic reviews, covering 99 studies, that occupational physical activity causes low back pain (LBP), although individual workers may attribute it to their work. There is no strong causal relationship between occupational physical activity and LBP, and there is conflicting evidence of an association (not causal) between LBP and bending, twisting, lifting, and pushing and pulling. There is strong evidence that assisting patients, manual handling, carrying, awkward postures, sitting, standing and walking does not cause LBP. Methodological weaknesses are common and need to be addressed in future research.
