Hemodynamic Response and Motor Functions Following Transcranial Direct Current Stimulation in Acute Stroke
Stroke, Acute
About this trial
This is an interventional treatment trial for Stroke focused on measuring Stroke, Acute, tDCS, Rehabilitation
Eligibility Criteria
Inclusion Criteria:
- Between 18 and 75 years of age
- First ever-acute ischemic unilateral stroke in the anterior circulation (ACA or MCA territory), MRI/CT scan result is thus required.
- Stroke onset from 2-10 days
- Good level of consciousness (alert)
- Free of any neurological antecedent, unstable condition that may increase the risk of stimulation such as epilepsy; although tDCS is believed to induce less or no risk of seizure and epileptic seizure have never been reported in tDCS study even in a study with active epilepsy (19).
- No significant carotid artery occlusive disease (< 50% internal carotid artery stenosis) as assessed by carotid duplex ultrasonography
- Modified Ranking Scale ≤ 4
Exclusion Criteria:
- Recurrent stroke
- Having score more than 20 points on the National Institute of Health Stroke Scale
- Be unable to understand the instruction.
- Presence of intracranial metal implantation, cochlear implant, or cardiac pacemaker.
- Having as excessive pain in any joint of the lower limb (numerical pain rating score > 7)
- Open wound or wound infraction on scalp
Sites / Locations
- Faculty of Physical Therapy, Mahidol University

Anodal transcranial direct current stimulation (tDCS) will be applied for 20 mins before conventional physical therapy (about 1 hour). Anodal on the motor area (M1) of the affected hemisphere, Cathodal on the contralateral supraorbital area. The current intensity is fixed at 1.5 mA and the current will flow continuously. The physical therapist will give an intervention program base on the same basic conventional physical therapy treatment. The scope of intervention is administered to improve motor functions and cerebral hemodynamic.
Cathodal transcranial direct current stimulation (tDCS) will be applied for 20 mins before conventional physical therapy (about 1 hour). Anodal on the supraorbital area of the affected hemisphere, Cathodal on the primary motor area (M1) of the unaffected hemisphere. The current intensity is fixed at 1.5 mA and the current will flow continuously. The physical therapist will give an intervention program base on the same basic conventional physical therapy treatment. The scope of intervention is administered to improve motor functions and cerebral hemodynamic.
Dual transcranial direct current stimulation (tDCS) will be applied over C3-C4 or the motor area (M1) for 20 mins before conventional physical therapy (about 1 hour). Anodal on the affected hemisphere, Cathodal on the unaffected hemisphere. The current intensity is fixed at 1.5 mA and the current will flow continuously. The physical therapist will give an intervention program base on the same basic conventional physical therapy treatment. The scope of intervention is administered to improve motor functions and cerebral hemodynamic.
Dual transcranial direct current stimulation (tDCS) in sham mode will be applied over C3-C4 or the motor area (M1) for 20 mins before conventional physical therapy (about 1 hour). Anodal on the affected hemisphere, Cathodal on the unaffected hemisphere. The physical therapist will give an intervention program base on the same basic conventional physical therapy treatment. The scope of intervention is administered to improve motor functions and cerebral hemodynamic .
