Reduction of pain symptomatology, verified through the Visual Analogue Scale, the application of the Short-form McGill Questionaire and the Pressure Pain Threshold at the pre and posttreatment moments, and the expected reduction is 50% or more in pain intensity and sensitivity for the group that received low intensity laser therapy (LLLT); and 20% or less in the parameters described above for the placebo group. Reduction of the levels of anxiety and stress for both groups (active laser and placebo), verified through the Beck Inventory Questionnaire and the dosage of the morning salivary cortisol at the pre and posttreatment moments, and the expected reduction is 50% or more for both groups.
