The use of transcranial direct current stimulation combined with lower limb motor training in neurology: A systematic review of the literature

Abstract

Background: Transcranial direct current stimulation (tDCS) is a neuromodulatorystimulation technique that can modulate a maladaptive excitation patternagainst neurological injury. The combined use of this technique with physicalrehabilitation has been widely discussed in the literature. Objective: To conducta review of studies that employed the tDCS combined with lower limb trainingto improve gait, balance and postural control in neurological patients. Methods:A bibliographic review was performed in the databases: Medline, Lilacs, Embase,Physiotherapy Evidence Database, Cochrane databases, Cinahl, Scielo andPubMed.Selected articles were scored and qualified based on the PhysiotherapyEvidence Database scale. Results: Nine studies involving the combination oftDCS and lower limb motor training for individuals with neurological problemswere included. Conclusion: Despite being widely studied scientifically, nogeneral consensus is yet found in the literature regarding the ideal tDCS administrationparameters, we suggest that the combined use with motor training maypotentiate the functional effects of therapy.
