Cathodal transcranial direct current stimulation (tDCS) will be applied for 20 mins before conventional physical therapy (about 1 hour). Cathode on the on the motor area (M1) of the affected hemisphere, anode on the supraorbital area of the unaffect hemisphere.Current intensity is fixed at 1.5 mA and current will flow continuously. 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 .

Anodal transcranial direct current stimulation (tDCS) will be applied for 20 mins before conventional physical therapy (about 1 hours). Anode on the motor are (M1) of the affected hemisphere, and cathodal on the supraorbital area of unaffected hemisphere. Current intensity is fixed at 1.5 mA and current will flow continuously. 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/Anodal tDCS will be applied in 1.5 mA, 20 mins before conventional physical therapy for 5 days. All experiments will be performed in random order for each subject.

gold standard and widely used tool to assess sensorimotor in stroke. The item from upper limb and lower limb section will be used. The items are rated on a 3-point ordinal scale as follows: 0 = unable to perform; 1 = partial ability to perform; and 2 = near normal ability to perform.

The participants will be asked to perform 2 items that consist of reaching a can and reaching a pen because two tasks is the most common reaching task of hand functions in daily living activities.

Subjects will sits on the chair and place their back against the chair. Timing will begin at "GO", the subjects will be asked to walk 3m, turn, walk back, and sit down. The stopwatch stops when the patient's buttocks touch the seat.

The TUG test is a commonly used screening tool to measure basic mobility correlating to dynamic balance. Start from sitting, stand up, walk 3 meters, turn around, walk back 3 meters and sit down. Timed to complete the task represent the body transfer and gait performance

The strength of UE (shoulder flexor, shoulder extensor, elbow extensor, wrist extensor) and LE (hip extensor, hip flexor, knee extensor and ankle dorsiflexor) will be assessed by hand-held dynamometer

cerebral blood flow velocity (CBFV), cerebral vasomotor reactivity (VMR) that is the capability of cerebral small vessels to respond to a stimulus
