Dynamic electrical neurostimulation (DENS) is a variant of transcutaneous electrical neurostimulation based on the use of biological feedback monitoring the surface impedance of the skin. The present study was designed to estimate the effectiveness of the application of dynamic electrical neurostimulation for the treatment of dorsalgias of the lumbar-sacral localization in comparison with the standard combined treatment including pharmacotherapy, massage, and therapeutic physical culture exercises. The data obtained indicate that the inclusion of DENS in the standard treatment protocol promotes the regression of pain and neurological symptoms; moreover, it accelerates the achievement of clinical remission.
