“…In the latter, about one-third, half the patients experienced some kind of pain relief. This phenomenon is well observed in studies involving neuromodulation in the treatment of pain 59,60 . Some studies have also observed a reduction of anxiety in volunteers allocated to placebo group 61 , an effect also observed in the present study.…”

BACKGROUND AND OBJECTIVES: In temporomandibular disorder, the pain is a very present and striking symptom, with a tendency to chronicity, through mechanisms of maladaptive neuroplasticity. In the face of this, transcranial direct current stimulation appears as a possible strategy for the treatment of chronic pain in the temporomandibular disorder. This study aimed to evaluate the efficacy of anodal transcranial direct current stimulation in the pain symptoms and anxiety levels in individuals with chronic myofascial temporomandibular disorder. METHODS: The participants received three different types of intervention in a randomized order: anodic in the primary motor cortex, in the dorsolateral prefrontal cortex and sham stimulation. RESULTS: There were significant improvements in clinical pain in all stimulation protocols, with a relief of approximately 40% (p=0.001). There was no significant difference in the effect of the transcranial direct current stimulation between the different types of stimulation (p=0.14). There was a positive impact on anxiety symptoms, leading to a significant decrease in state anxiety levels (p=0.035) and trait (p=0.009). CONCLUSION: The use of the transcranial direct current stimulation improved the health status of patients with chronic myofascial temporomandibular disorder, promoting pain relief, decreased level of anxiety, and quality of life.

“…TES can be classified based on the current form to transcranial alternating current stimulation (tACS), transcranial direct current stimulation (tDCS), and transcranial random noise stimulation (tRNS). The technique has applications to different neurological and psychiatric disorders such as stroke [2,3], depression [4,5], epilepsy [6,7] and chronic pain [8,9]. TES applies weak currents in the range of 1-2 mA via at least two electrodes to change the brain activity level.…”

BackgroundAdvances in transcranial electric stimulation (TES) were hampered by the conventional rubber electrodes manually attached to the head with rubber bands. This procedure limited montages to a few electrodes, was error prone with respect to electrode configurations and was burdensome for participants and operators. A newly developed flexible cap with integrated textile stimulation electrodes was compared to the conventional setup of rubber electrodes fixated by rubber bands, with respect to usability and reliability. Two operators applied both setups to twenty healthy volunteers participating in the study. Electrode position and impedance measures as well as subjective evaluations from participants and operators were obtained throughout the stimulation sessions. ResultsOur results demonstrated the superiority of the flexible cap by means of significantly higher electrode configuration reproducibility and a more efficient application. Both, operators and volunteers evaluated the flexible cap as easier to use and more comfortable to wear when compared to the conventional setup. ConclusionIn conclusion, the new cap improves existing and opens new applications scenarios for TES.

“…A maior parte dos estudos com TECNIs apresentavam apenas uma única sessão de ETCC em desenhos não clínicos. Desta forma, os dados eram muito limitados em termos de segurança cognitiva após múltiplas sessões de ETCC em contextos clínicos (85).…”
