We will use the RANDBETWEEN function in Excel for making randomization order. Allocation concealment will be performed by the secretary of the assessment center, Blinding description: All participants in this study will be blind to their allocation to study groups (motor cortex stimulation, cognitive cortex stimulation and placebo). The outcome assessorو before and after intervention, will be blind to the allocation as well. However, the physiotherapist, study designer, statistical analyst and the committee of safety and data supervision will not be blind. N/A Stroke. Intervention 1: First intervention group: Motor cortex stimulation. Intervention 2: Second intervention group: Cognitive cortex stimulation. Intervention 3: Control group: Placebo. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is I have to provide all the data to the research sponsor.
