Introduction

Accurate measurement of lumbar spine mobility can help to assess the severity of a low back pain, monitoring its course and evaluating treatment effectivity. The results obtained with the Inclinometer and 3D Movement Analysis (optoelectronic) in a group of patients and controls are presented to evaluate the differences with both techniques between both populations.

Material and methods

A total of 47 subjects with chronic low back pain and 33 healthy controls were studied using both the Double Inclinometer technique and 3D Movement Analysis of the lumbar spine. Measurements were obtained in a single session of flexion, extension, right and left lateral flexions and flexion velocity.

Results

Range of motion was greater in men than in women in all directions of movement, however, based on the analysis of the variance, the differences were not statistically significant (p>0.05). Mean values were significantly higher in all variables in healthy subjects (flexion p=0.0001; extension p=0.05; R lateral flexion p=0.0027; L lateral flexion, p=0.0002; flexion velocity p=0.00001). Cutoff values for each variable are shown, indicating their sensitivity and specificity.

Discussion and conclusions

In the population studied by 3D Movement Analysis, lumbar mobility was similar en both genders, however, larger samples are needed to confirm these data. The main conclusion of the study is that this technique has excellent capacity to discriminate patients suffering chronic lumbar pain from the normal population. While restriction of motion is a well-known fact, the overwhelming statistical evidence and the normative data presented show that motion analysis is an excellent tool in the diagnosis of chronic low back pain, that is especially useful appears the velocity of flexion.
