OBJECTIVE: Evaluate the effect of the association of low doses of naltrexone (LDN) and transcranial direct current electrical stimulation (tDCS) on the quality of life of patients with fibromyalgia (FM).
METHODS: This is a randomized clinical trial in which 86 women aged between 18 and 65 years and diagnosed with FM were included. Patients were randomized between LDN + tDCS (n = 21), LDN + Sham-tDCS (n = 22), Placebo + tDCS (n = 22) or Placebo + Sham-tDCS (n = 21), receiving 21 days of medication and 5 days of association. Patients underwent the following procedures: sociodemographic questionnaire and Fibromyalgia Impact Questionnaire (FIQ), subdivided into function, overall impact and symptoms. The data were analyzed using the SPSS 20.0 program, using Friedman's test followed by Wilcoxon's Post-Hoc (significance when P <0.05).
RESULTS: There was no significant difference between groups in the baseline data (age, BMI, education), demonstrating to be a homogeneous sample. The LDN + tDCS group showed a significant difference when comparing the fourth assessment with the first in the function domain (P = 0.005), when comparing the eighth assessment with the first, significant differences were found in the total impact and symptoms (P = 0.004 and P < 0.001, respectively). The other groups showed a significant difference only in the symptoms domain, when the eighth assessment was compared with the first (P = 0.003 for all).
CONCLUSIONS: through this study it was possible to conclude that the association of LDN and tDCS is efficient in improving the impact of the syndrome on patients.
