简要总结
Stroke represents one of the main causes of adult disability and will be one of the main contributors to the burden of disease in 2030. However, our healthcare systems do not have enough resources to cover the current demand let alone its future increase. There is a need to deploy new approaches that advance the current rehabilitation methods and enhance their efficiency.
One of the latest approaches used for the rehabilitation of a wide range of deficits of the nervous system is based on virtual reality (VR) applications, which combine training scenarios with dedicated interface devices. On the other hand, recent studies have shown the potential of transcranial direct current stimulation (tDCS) to restore motor function in hemiparetic stroke patients. It must be emphasized, however, that so far little work exists on the quantitative assessment of the clinical impact of VR based approaches in combination with tDCS protocols. We hypothesize that the combination of VR-based motor rehabilitation protocols with concurrent anodal tDCS can boost functional recovery, and may achieve superior effects when compared to 3 alternative treatments: 1) VR without tDCS, 2) occupational therapy with tDCS, and 3) occupational therapy without tDCS.
The findings derived from this study will contribute to establish a novel and superior neurorehabilitation paradigm that can accelerates the recovery of hemiparetic stroke patients. Besides the clinical impact, such achievement could have relevant socioeconomic impact.

入选标准
- •Patients with hemiparesis secondary to first ever ischemic or hemorrhagic stroke (Medical Research Council score > 2).
- •Older than 18 years old.
- •Sufficient cognitive capacity to understand and follow the experimental instructions (Mini-Mental State Evaluation > 20).
排除标准
- •Presence of a condition or abnormality that in the opinion of the Investigator would compromise the safety of the patient or the quality of the data.
- •Epilepsia and metal implants. A diagnostic EEG will be performed by the Department of Clinical Neurophysiology of the hospital to detect epileptic paroxysmal in order to include or exclude patients in the study.
- •Low Cognitive capabilities that prohibits the execution of the experiment Arteriovenous malformation
- •Severe associated impairment such as spasticity, communication disabilities (sensorial, mixed or global aphasia or apraxia), major pain or other neuromuscular impairments or orthopaedic devices that would interfere with the correct execution of the experiment (Modified Ashworth Scale > 3)
- •History of serious mental-health problems in acute or sub acute phase
- •Refusal to sign the consent form
- •Previous surgeries opening the skull.
- •Active or recent substance abuse or dependence within the past year.
- •Pregnancy, breastfeeding, unwillingness to practice birth control during participation in the study.
