INTERVENTIONAL
Conditions
Summary
This clinical trial aims to evaluate the effect of different types of tDCS modulation with mCIMT in improving affected upper-limb motor function for stroke patients. The main question it seeks to answer: Which type of tDCS (bi-hemispheric, anodal, or cathodal) combined with the mCIMT program leads to greater improvement in affected upper-limb function in patients with stroke? Researchers will compare these three types of tDCS to a sham tDCS. To see which kind of tDCS protocol combined with the mCIMT program will be more effective in improving affected upper-limb function for stroke patients. Participants will: 1. Participants will receive 12 sessions of mCIMT combined with tDCS or mCIMT alone. 2. Visit the clinic three times a week for four weeks. 3. Participants will do fMRI and TMS before and after the program and three times of assessment before and after two weeks after the program.

Interventions
20 minutes of anodal tDCS followed by 1 hour of the mCIMT program. The anodal electrode will be placed over the ipsilesional M1 (primary motor cortex, C3 or C4 according to EEG 10/20 system), and the cathodal electrode over the contralateral supraorbital area (Fp1 or Fp2) ). Leading to subthreshold depolarization to promote cortical excitation. And twelve different oriented tasks will be used during the 1-hour training period.
20 minutes of cathodal tDCS followed by 1 hour of the mCIMT program. the cathodal electrode will be placed over the contralesional M1, and the anodal electrode over the contralateral supraorbital area (Fp1 or Fp2). leading to subthreshold polarization to promote cortical inhibition. And twelve different oriented tasks will be used during the 1-hour training period.
20 minutes of Bihemispheric tDCS followed by 1 hour of the mCIMT program. the cathodal electrode will be placed over the primary motor cortex (M1) of the contralesional hemisphere and the anodal electrode will be placed above the ipsilateral M1 position (C3 or C4 positions, according to the 10/20 EEG system). And twelve different oriented tasks will be used during the 1-hour training period.
20 minutes of sham tDCS followed by 1 hour of the mCIMT program. the same stimulation place and parameters will be used as in the anodal group. However, after 30 seconds of stimulation, the stimulator will switch off. This provides the participants with the experience of the initial itchy sensation that occurs during tDCS, which is required for efficient masking. And twelve different oriented tasks will be used during the 1-hour training period.
