Tratamento da dor orofacial em pacientes com fibromialgia: efeito da Laserterapia versus infiltração anestésica em pontosgatilho

Abstract

This trial aimed to evaluate the effect of lasertherapy and anesthetic injections in the treatment of orofacial pain in patients with fibromyalgia , at the city of João Pessoa - PB . In the first stage of the study, a questionnaire was applied to participants , which allowed us to assess the location and intensity of the initial orofacial pain research. The second stage began with the random division of the patients into two different groups for treatment : Group A, treated with anesthetic infiltration into four sessions, and Group B , treated by lasertherapy in 12 sessions (with Laser AsGaAl 780nm and ED=50J/cm2). In the third stage, after completion of treatment in both groups, patients were submitted to a new questionnaire, proceeding to data analysis. Both treatments were quite effective as the goal of reducing and even extinguish the pain in the head and neck. The t test was performed to compare two paired samples, considering the treatment of Group A, results in a statistically significant difference from the ' Degree of Orofacial Pain intensity ' in the moments Before x After, with t=103.422 with degrees of freedom (df)=32 and p-value=0.000<&#945;=0.05. Considering the B treatment, resulted in statistically significant differences in relation of the ' Degree of Orofacial Pain intensity ' in the moments Before x After, with t=12,178 with degrees of freedom (df)=32 and p - value=0.000< &#945;=0.05. For comparison of two independent samples, t=0.742 with (df)=64 and significance p - value=0.461>&#945;=0. These results indicate no significant difference in mean intensity of Orofacial Pain after each type of treatment, however, due to the question " improved well being " , we validate the additional properties of the Low Level Lasertherapy ( primary, secondary and therapeutic ) as better as infiltration with anesthetics. Showing up lasertherapy as a promising treatment for headaches and neck in patients with Fibromyalgia Syndrome.
