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.
