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.

Resonant sustained oscillations are applied in the following areas

  • general column.
  • lumbar muscles, and paraspinal muscles,
  • sacral decompression oscillatory
  • Opening by lateral vertebral lumbar rhythmic swing.
  • Balancing and pelvic decompression
  • Swing-lumbar vertebral rotation.
Other Name: oscillatory movement
Active Comparator: CONVENCIONAL: column exercise group
Patients who applied the conventional treatment of hospital
Other: column exercise group
  • paraspinal muscle stretching exercises
  • postural correction
  • mobilization exercises thoracic and lumbar
  • Motor control exercises
Other Name: motor control
