Study of Effectiveness of Pold in Chronic Nonspecific Low Back Pain

Through this research is to conduct a pilot clinical trial in the treatment of chronic nonspecific low back pain (degenerative and mechanical), by comparing two groups, one that will apply a technique of physiotherapy by passive movement of the column with oscillations in axial rotation at a frequency of 1.5 to 2 cps (resonance) of low amplitude (called "Pold Concept"), another group that applies the standard protocol of treatment for this condition, as used in the hospital where performed the study. It will compare the levels of efficiency and effectiveness of each treatment and the comparison between them. This will measure the perception of pain intensity and disability.
