Description of intervention(s) / exposure
For the total sample of Patients with nonspecific CLBP and a pronated foot posture index we evaluate the Oswestry's Disability Index Questionnaire for Lower Back Pain (ODI) and a visual analogue scale (VAS) for pain. The outcome measure of CLBP, assessed using the Oswestry Disability Index (ODI) and the Visual Analogic Scale (VAS) at the moment of the inclusión in the study. We evaluate the foot posture using the foot posture index. We are not going to do any intervention, only a observacional meassures. Is only the day of the exploration, only one meassure.

Summary
Brief summary
Identify the foot posture index and it´s response in CLBP.
We evaluate the foot posture and the CLBP in patients with this pain to valorate if there is a disturb in the foot posture that can influence the chronic low back pain
It´s an observational study

We hypothesized that the anormal biomechanical of the foot may contribute to the low back pain symptoms. This question represents an important benefit for patients and for the public health system by reducing expensive treatments, such as surgery or long periods of rehabilitation.
