Comparative Study
Comparison of the lumbar flexion angle and repositioning error during lumbar flexion-extension in young computer workers in Korea with differing back pain.
Differences in LBP symptoms are particularly important with regard to the controversy over repositioning error because there can be considerable variation in the pattern of LBP symptoms in a heterogeneous LBP group. For this reason, several researchers have suggested that a study of subdivided LBP types is needed. Indeed, some recent studies have attempted to differentiate LBP subgroups. ⋯ This study suggests that lumbar hyper-mobility occurred and proprioception of the lumbar segment was decreased in people with LBP associated with lumbar flexion compared with people with LBP associated with lumbar extension. We also suggest that a lumbar repositioning error measurement using the lumbar flexion-extension test may be a more effective evaluation method in people with LBP associated with lumbar flexion than in those with LBP associated with lumbar extension.

Little research is available on low back biomechanical stresses that obese and overweight workers experience from manual load lifting. ⋯ In light of previous research on spine, bone and obesity, the study results seem to suggest that severely obese individuals are likely at an increased risk of lifting-related low back pain compared with normal weight individuals.
