Objective assessment with establishment of normal values for lumbar spinal range of motion.
The purpose of this article is to present an assessment method, in conjunction with age-related normal values, for lumbar spinal range of motion. Lumbar flexion, lumbar extension, and right and left lateral flexion were measured on 172 subjects by a combination of goniometry and spinal distraction techniques. Normal values are given for six age groups; each group had a range of 10 years. The results demonstrate that a significant decrease in lumbar spinal range of motion is expected with increasing age. The interobserver reliability based on 17 subjects was substantial for the four measurements taken; coefficients ranged from +.76 to +1.0. The information may prove useful to the clinician as an improved method for assessing the lumbar spine.
