| Summary: | To develop a systematic review that examines existing evidence on the effects of non-invasive brain stimulation (NIBS) in motor performance in dual-task conditions, in individuals with or wihtout phatology. A systematic search of the literature was conducted in five databases (PubMed, Web of Science Core Collection, Scopus, Cochrane Central Register of Controlled Trials and EBSCO Datasets) and, to retrieve potentially missing records, a manual search strategy was also conducted. Randomized controlled trials (RCTs ) and nonrandomized controlled trials with a sham stimulation group that examined the effects of NIBS interventions on motor performance under dual-task (DT) conditions were included. Data was extracted on study design, participants, and intervention characteristics; types of motor and cognitive tasks used for single and DT assessment, DT prioritization instructions, results by outcome measures and statistical data. Of the 816 articles identified, 42 met the inclusion criteria. After screening for records from the same trials, a total of seven r TMS studies were evaluated. Two rTMS and five tDCS ongoing trials were also identified. For the rTMS studies, there was a significant Effect on DT gait performance in high frequency stimulation targeting the dorsolateral prefrontal córtex. Analysis of the tDCS studies suggest that this method allows for improvements in walking and gait, balance, standing and postural control, especially in multisession studies. This review suggests that gait, balance, standing and postural control under DT conditions can be improved after single and multi-session of rTMS and tDCS. Still, there is a need to define the number of sessions, frequency and intensity, target region and motor and cognitive tasks assessmentwich are the most effective. Further research is strongly recommended to provide guidelines for the use of NIBS in clinical rehabilitation.
