Brief summary

We hypothesize that, after applying the electroanalgesia treatment protocol, subjects with chronic low back pain will experience an imporvement in pain perception and lumbar functionality. Although the use of electrotherapy has been put into question in several studies, we hypothesize that the effectiveness of electrotherapy is strongly related to the parameters used for treatment

Interventions

ELECTROANALGESIA PROTOCOL The electroanalgesia treatment protocol will consist of applying transregional interferential current to the lower back region. The stimulation parameters will be: intensity of 4000Hz, amplitude-modulated frequency of 100Hz, sweep of 50 Hz, and pulse duration of 130 micros. The subjects will be placed in a prone position with the lower back area unclothed. The electrotherapy treatment will be based on the interferential current and tetrapolar method; that is, with four electrodes and two intersecting channels, with a rectangular stimulus 1/1, with electrodes of 75 cm2 in area, for 25 minutes. The four self-adhesive electrodes will be symmetrically placed onto each subject's lower back region, at the level of L1 and L5, in a crossed pattern. The treatment will undergo ten treatment sessions, applied once a day from Monday to Friday over a two weeks period of time
