简要总结
Rehabilitation options for stroke survivors who present severe hemiparesis in chronic stages are limited and may end in compensation techniques that involve the use of the less affected arm to achieve some degree of functional independence. Transcranial direct current stimulation (tDCS) is a non-invasive technique that has been used after stroke to promote excitability of the surviving neural architecture in order to support functional recovery. Interestingly, cortical excitability has been reported to increase when tDCS is combined with virtual reality. This synergetic effect could explain the promising results achieved by preliminary experimental interventions that combined both approaches on upper limb rehabilitation after stroke. The objective of this study is to explore the use of these interventions in subjects with severe hemiparesis and to determine its efficacy in comparison to conventional physical therapy
