To determine the increase in pain tolerance through Algometry\n\nSecondary outcomes:\n\nThe improvement in pain after treatment with daily measurements for 7 days will be assessed using the TotPar Scale The reduction in pain will be assessed using the Sum of Pain Intensity Difference (SPID) Scale by comparing the differences in scores observed between pre-treatment and post-treatment with daily measurements for 7 days Reduction in the 10-point visual analogue scale for pain. Need for rescue medication\n\nSafety endpoint:\n\nEvaluate adverse events that occurred during the trial, after signing the Informed Consent Form (ICF).\n\nSafety outcomes:\n\nEvaluate safety through data obtained in clinical and physical assessments, and in specific assessments of the clinical trial (immediately after signing the ICF).\n\nEvaluate the rate of occurrence of non-serious and serious adverse events, related and unrelated to the treatment groups throughout the clinical trial.', 'detailedDescription': "Trial Population Patients with primary or secondary low back pain, aged between 18 and 65 years, who attended the Institute of Orthopedics and Traumatology of the Hospital das Clínicas of the Faculty of Medicine of the University of São Paulo (IOTHCFMUSP) acupuncture clinic.\n\nTrial Design\n\nClinical, superiority, double-blind, randomized trial with two parallel groups:\n\n* Test Group: Will receive an auricular laser application at the points indicated for this treatment and that are active (through a point locator device) using a 660 nanometer red laser with the appropriate Nogier frequency, 2 joules per point. In addition, an infrared laser will be applied at the frequency\n* Comparator group: will receive a touch on the skin at the same points with a non-laser emitting pen.\n\nBoth patients will wear opaque protective glasses and, therefore, will not be able to observe the application. The patient must continue to use the prescribed medications.\n\nExperimental procedure:\n\nLaser French Auriculotherapy using the ECCO REABILITY device and dual pen with red laser with a wavelength of 660 nm, manufactured by Ecco Fiber Optics and Devices, using the ideal Nogier Frequency for each region, with the application of 2 J per point and a power of 100 mW. For the active group, a 120 mW active tip, red laser with 660 nm, pulse width of 1.2 milliseconds will be used.\n\nComparator procedure:\n\nPlacebo laser using the ECCO REABILITY device and sham pen, both manufactured by Ecco Fiber Optics and Devices. For the control group, a placebo tip with red laser 660 nm with 1 mW of power, pulse width of 1.2 milliseconds will be used.\n\nApplication method Single session. The auriculotherapy treatment protocol will be adapted according to each patient. The Nogier mapping will be applied: lumbar and sacral spine area; Lumbar muscles in the posterior wall, thalamus, zero, zero', Shen Men and prefrontal cortex, main sensory and master point of the spine, in addition to the radian technique using the corresponding point in the auricular helix. The points to be used must be active according to the EL30 Finder differential pen point locator device manufactured by NKL Medical DevicesL.\n\nA red laser with a wavelength of 660 nm will be used with the ideal frequency for each location (Nogier frequencies) with an intensity of 2 joules per point. Patients randomized to the placebo group will undergo the same procedures, however a placebo pen will be used.\n\nIf the pain is located on one side, the application will be made in the ear on the same side as the affected side. If the pain is bilateral, the application will be made in both ears. If the pain only affects the midline, the application will be made in the ear on the same side as the dominant hand.\n\nMethodology Blinding The procedure will be performed by an unblinded investigator. The patient will be blinded by means of an eye protector that blocks his/her vision. The assessment of pain scales and algometry will be performed by a blinded investigator.\n\nThere will be 11 visits in total Visit 0 (V0) - Initial visit\n\n* Participant clarification about the protocol\n* Signing of the informed consent form\n* Assessment of the inclusion and exclusion criteria;\n* Randomization of the research participant; This visit will be performed by an unblinded investigator\n\nVisit 1 (V1) - Screening visit\n\nAfter the participant consents to participate in the trial, the following procedures must be performed:\n\n* Collect demographic data;\n* Assess and record medical history;\n* Perform a complete physical examination;\n* Record previous medications used in the last two weeks;\n* Apply the initial scales\n* Test algometry on the muscles affected by pain. This visit will be performed by a blinded investigator\n\nVisit 2 (V2) - Randomization and treatment visit • Apply the experimental or sham treatment according to randomization This visit will be performed by an unblinded investigator\n\nVisit 3 (V3) - Reassessment visit\n\n• Reapply the TotPar and SPID scale and repeat algometry This visit will be performed by a blinded investigator\n\nVisit 4 (V4) - Telephone reassessment visit\n\n* After 24h of V3\n* Reapply the TotPar and SPID scale This visit will be performed by a blinded investigator\n\nVisit 5 (V5) - Telephone reassessment visit\n\n* After 24h of V4\n* Reapply the TotPar and SPID scale This visit will be performed by a blinded investigator\n\nVisit 6 (V6) - Telephone reassessment visit\n\n* After 24h of V5\n* Reapply the TotPar and SPID scale SPID This visit will be conducted by a blinded investigator\n\nVisit 7 (V7) - Telephone reassessment visit\n\n* After 24h from V6\n* Reapply the TotPar and SPID scale This visit will be conducted by a blinded investigator\n\nVisit 8 (V8) - Telephone reassessment visit\n\n* After 24h from V7\n* Reapply the TotPar and SPID scale This visit will be conducted by a blinded investigator\n\nVisit 9 (V9) - Telephone reassessment visit\n\n* After 24h from V8\n* Reapply the TotPar and SPID scale This visit will be conducted by a blinded investigator\n\nVisit 10 (V10) - Closing visit\n\n* After 24h from V9\n* Reapply the TotPar and SPID scale\n* Final reassessment\n* Referral for follow-up This visit will be conducted by a blinded investigator.\n\nStatistical Plan The outcome is of an ordinal qualitative nature and, therefore, the one-tailed non-parametric Mann-Whitney-Wilcoxon test will be used to verify whether laser is superior to sham acupuncture in reducing pain.\n\nThe outcome is of an ordinal qualitative nature and, therefore, the Fischer test will be used to verify whether laser is superior to sham acupuncture in reducing pain.
