The relationship between anthropometric, postural, muscular, and mobility characteristics of males ages 18-55.

Abstract

Three hundred twenty-one males, ages 18-55, had standardized tests to determine height, weight, Davenport Index, leg length inequality, determination of flexion and extension torques, flexion/extension balance, range of motion, straight leg raising, and lumbar lordosis. A total of 106 (33.0%) had never experienced low-back symptoms; 144 (44.9%) had or were having moderate low-back pain (LBP); and 71 (22.1%) had or were having severe low-back symptoms. These three subgroups showed no significant differences in height, weight, Davenport Index, lumbar lordosis, or leg length inequalities. LBP patients had less flexor and extensor strength and were flexor overpowered, had diminished range of motion for spinal extension and axial rotation (P = 0.003, P = 0.0005), and diminished straight leg raising capacity (P = 0.04). A multivariate correlation matrix demonstrated no typical pattern of associated abnormalities except a diminished spinal range of motion in one plane was associated with the anticipated diminishment in all other planes of motion, and often with greater restrictions of straight leg raising tests.
