The purpose of this article is to present an assessment method, in conjunction with age, sex, and occupation-related normal values, for thoracolumbar spinal range of motion in Korea healthy adults. The thoracolumbar spinal range of motion, flexion, extension, right side lateral flexion, and right and left side rotation were measured on 160 subjects by a goniometry.

The results were as follows;

1) The average thoracolumbar spinal range of motion in healthy adults are 53.1±12.9⁗ in flexion, 39.9±12.2⁗in extension, 46.2±8.9⁗ in lateral flexion, 27.6±7.3⁗and 29.5±8.2⁗ in right and left side rotation.

2) Although there are some exceptions, thoracolumbar spinal range of motion are decreased gradually with increasing age.

3) The female adults shows increased range of motion in flexion, extension, and lateral flexion than male, but no significant difference in both side rotation between sexes.

4) The white coloured shows increased thoracolumbar spinal range of motion to all directions than laboured.
