Transcranial Direct Current Stimulation Associate to Constraint Induced Movement Therapy Over Premotor Cortex in Severe Stroke


Lead sponsor: Federal University of Paraíba

Brief Summary

The purpose is to compare the effects of tDCS and constraint induced movement therapy (CIMT) in the premotor cortex vs. primary motor cortex in severely subacute stroke survivors.

Detailed Description

Stroke survivors experience one or more movement-related impairments and activity limitations. In this sense, the premotor cortex (PMC) can be considered as an alternative locus for post-stroke rehabilitation. In relation to physical rehabilitation protocols, associate to neuromodulation, the investigators have chosen a standardized physical therapy protocol for this study, the Constraint Induced Movement Therapy (CIMT), which presents evidence of good therapeutic results. The investigators hypothesized that applying tDCS and CIMT over the PMC promotes motor restoration in stroke patients.
