Anthropometry, spinal canal width, and flexibility of the spine and hamstring muscles in 45-55-year-old men with and without low back pain.
One hundred fifty 45-55-year-old men were divided into three groups: those with healthy backs, recurrent low back pain (LBP), and chronic LBP. These groups were studied with respect to anthropometry, spinal canal width, spinal sagittal configuration and flexibility, and the flexibility of the hamstrings musculature with straight leg raising (SLR). There were no differences between the groups with respect to anthropometry. The group with healthy backs had significantly greater lordosis and sagittal flexibility than the other groups. The width of the spinal canal was correlated to body height. The SLR test showed significantly higher values in the group with healthy backs and in the recurrent pain group than in the chronic pain group. The possible role of restoring normal range of motion to minimize the risk of LBP recurrence is discussed.
