Intervention type: OTHER
Group type: EXPERIMENTAL
Intervention: Cryotherpy
Description: Cryotherapy will be used by means of ice packs over a painful region. The ice will be crushed inside a bag so that it is in an ideal size that provides a coupling in a painful column in the lumbar spine; Once it has been inserted in the plastic bag and before closing it all the air must be removed to avoid a faster thawing of the ice and have difficulties of coupling.

Intervention: TENS Burst
Description: The TENS Burst therapy will be performed using the KLD Sonophasys EUS 0503 electrotherapy device connected in the current therapy mode with the following parameters: 4Hz frequency, high pulse duration of 200 μsec and the current intensity will be at the maximum amplitude To generate visible muscle contraction without generating pain / discomfort. A channel will be used using self-adhesive electrodes arranged parallel to the erector muscle of the spine, so that the region to be treated is between the electrodes.

Intervention type: OTHER
Group type: PLACEBO_COMPARATOR
Intervention: TENS Burst Placebo
Description: The TENS Burst placebo therapy will be performed using the KLD Sonophasys EUS 0503 electrotherapy device connected in the current therapy mode with the following parameters: 4Hz frequency, high pulse duration of 200 μsec and the current intensity will be on but without Produce the effects of visible muscle contractions because the channel will not be properly coupled in the apparatus so that the stimulation does not reach the patient. A channel will be used using self-adhesive electrodes arranged parallel to the erector muscle of the spine, so that the region to be treated is between the electrodes.

Intervention: Education
Description: After the electrophysical intervention, a moment of education and awareness will be held, in which the participants will receive information about the purpose of the treatment; Anatomy and biomechanics of the lumbar spine; Chronic non-specific back pain; Cognitive, emotional, genetic, social, and lifestyle factors; Intrinsic and extrinsic physical factors, biopsychosocial model: beliefs of pain and hypervigilance; Concepts of joint protection; Energy conservation and general guidelines.
