Combined study of transcranial direct current stimulation and electroencephalography for the analysis on upper limb function: a systematic review

Neurological disorders can directly affect basic functions of the upper limbs, leading to an alteration in or loss motor capacity and hindering performance activities daily living. Transcranial direct current stimulation (tDCS) is a noninvasive technique capable modulating cortical excitability, favoring both brain activity neuroplasticity. The objective was systematize discuss effects transcranial combined with electroencephalogram for analysis limb movements individuals neurological impairment. For such, following research question used: Is use tDCS EEG effective movements? A systematic review performed international network databanks using criteria: (1) design: randomized controlled clinical trial; (2) population: healthy impairment; (3) intervention: EEG; (4) control group different intervention no intervention; (5) outcome: movement function. Eight arti-cles were selected, revealing consensus on parameters use. Few studies have evaluated tDCS, physical therapy electroencephalogram. small number methodological variation hinder determination EEG. Further are needed define ideal quantity session, intervals between sessions administration concomitant tDCS.
