This study will investigate whether combining virtual reality-based mirror therapy (VRMT) and transcranial direct current stimulation (tDCS) alongside conventional physical therapy (CPT) will significantly improve hand function for patients with stroke compared to using VRMT or tDCS alone.
More than half of stroke survivors suffer from upper-limb dysfunction that persists years after stroke, negatively impacting patients' independence and, therefore, affecting their quality of life. Motor rehabilitation is required after a stroke to facilitate motor recovery. More importantly, finding new ways to maximize patients' motor recovery is a core goal of stroke rehabilitation. Thus, researchers have explored the potential benefits of using advanced technologies such as virtual reality-based mirror therapy (VRMT) and transcranial direct current stimulation (tDCS) to boost the brain's responses to interventions and maximize the effects of rehabilitation to improve upper-limb recovery post-stroke. However, the potential impact of combining VRMT and tDCS on upper limb functions for patients with stroke has not been explored. Therefore, the goal of this study is to investigate whether combining virtual reality-based mirror therapy (VRMT) with transcranial direct current stimulation (tDCS) alongside conventional physical therapy (CPT) will significantly improve hand function for patients with stroke compared to using VRMT or tDCS alone.
The participants will be randomly assigned into one of the four groups: (1) the anodal tDCS + VRMT group, (2) the anodal tDCS alone group, (3) the VRMT alone with sham tDCS group, and (4) the CPT with sham tDCS group. All groups will receive CPT as part of the treatment. Functional scales will be used before and after the intervention to assess upper motor functions. These measures include the Fugl-Meyer Assessment, Wolf Motor Function Test, Box and Block Test, Nine-Hole Pegboard Test, and Stroke Impact Scale-16 (SIS-16). In addition, physiological measures such as transcranial magnetic stimulation (TMS) and task-based fMRI.

| Transcranial Direct Current Stimulation | Device | tDCS will be used during the sessions. The anodal tDCS (2 mA) will be applied for 20 minutes. Continuous, direct currents. The anodal electrode will be positioned over the ipsilesional primary motor cortex (M1) (C3 or C4, international 10-20 system) of the affected hemisphere and the cathodal electrode over the contralateral orbit. |

| Fugl-Mayer Upper limb assessment (FMA) | FMA is a performance-based impairment measure particular to strokes, designed to assess motor functioning, balance, sensory, and joint functionality. It consists of five domains, which have 155 total items. The full potential scale score is 226. Scale items are scored based on the ability to finish the item using a 3-point ordinal scale. Motor score: from 0 to 100, 66 points for the upper extremity and 34 points for the lower extremities. | at baseline, and after 2 weeks, and after intervention ( 4 weeks). |
| Wolf motor function test (WMT) | WMT, consisting of timed and practical tasks, measures the motor function of the upper extremity (UE). The WMFT has 17 items in the most common version. The first six items involved timed functional tasks; items 7 and 14 were strength tests, and the final nine analyzed the participants' movement quality while carrying out various tasks. Items scored on a 6-point scale, with lower scores indicating lower levels of functioning. | at baseline, and after 2 weeks, and after intervention ( 4 weeks). |
| box and blocks test (BBT) | BBT assesses manual dexterity of the hand. It requires subjects to lift and release 2.5 cm³ cubes to move them from one compartment to another. BBT comprises 150 blocks. The test should begin with the unaffected upper limb to practice and record baseline values. The score is defined as the number of blocks transferred correctly within 60 seconds. | at baseline, and after 2 weeks, and after intervention ( 4 weeks). |
| Nine-Hole Peg Test (NHPT) | NHPT was developed to assess finger dexterity. It is made up of a nine-peg square board. The board has holes on one end for the pegs to fit into, and it also has a shallow circular dish on the other for storing the pegs. The patient is instructed to quickly insert the pegs into the holes on the board after taking each one out of a container as part of the NHPT. Then, one by one, clients must bring the pegs out of the holes and put them back into the container. Scoring is according to how long it took them to finish the test activity, measured in seconds. |
| Measure | Description | Time Frame |

| Stroke impact scale-16 (SIS-16) | SIS is a self-report health status measure specific to the stroke population. It consists of 16 items from the four physical domains (strength, hand function ADL/IADL, and mobility). | at baseline, and after 2 weeks, and after intervention ( 4 weeks). |
| transcranial magnetic stimulation (TMS) |

TMS measures cortical excitability, which is non-invasive magnetic stimulation using brief-duration, fast-pulsating, or pulsed magnetic fields to induce electrical currents targeted at spatially separate parts of the cerebral cortex using a computerized, electromechanical medical device. |
| at baseline, and after intervention ( 4 weeks). |
| Functional magnetic resonance imaging (fMRI) | fMRI technique uses MRI technology to evaluate brain activity by looking for variations in blood flow. The coupling between cerebral blood flow and neuronal activation is the basis for this method. The participants will be trained on the task before the experimental session. A block design will be used in the fMRI scan; each fMRI scan lasts for 6 minutes, divided into six blocks with an interval of 30 seconds of task, 15 repeated contractions, each contraction lasting 2 seconds, interspersed with 30 seconds of rest. | at baseline, and after intervention ( 4 weeks). |
