Brief Summary

The injury and remodeling mechanism about upper extremity motor network after stroke is not clear. There are few studies on the motor network covering cortex, white matter and blood perfusion at the time. Some studies have shown that metal imagery activates the cortex through active mental simulation. Our previous study has shown that passive application of transcranial direct current stimulation causes subthreshold polarization and promotes the effective integration of residual brain high-level network. This study proposes a hypothesis: transcranial Direct Current Stimulation + Motor Imagery combines active and passive neuromodulation techniques to produce dual channel effect, which can synergistically excite motor cortex, remodel the motor network and optimize cerebral perfusion. The research contents include clarify the effect of transcranial Direct Current Stimulation + Motor Imagery neuromodulation therapy through comprehensive randomized controlled trial study; present the process of brain injury and secondary neural plasticity through the motor network construction, functional connectivity strength and cerebral perfusion with Blood Oxygen Level Dependent, Diffusion Tensor Imaging and Arterial Spin Labeling multimodal magnetic resonance technology; calculate the correlation between motor score and brain functional network, extract the key nodes that can promote the motor network remodeling. The research results are expected to provide preliminary theoretical foundations for further research on the injury and remodeling mechanism about upper extremity motor network after stroke.

Primary Outcomes (8)

  • Behavioral assessment by Fugl-Meyer Assessment for Upper Limb

    Complete the scale at baseline

    Baseline

  • Behavioral assessment by Fugl-Meyer Assessment for Upper Limb change

    Change from baseline Action Research Arm Test immediately after intervention is obtained by subtracting the baseline from the later Fugl-Meyer Assessment score.

    Immediately after intervention

  • Behavioral assessment by Action Research Arm Test

    Complete the above scale at baseline

    Baseline

  • Behavioral assessment by Action Research Arm Test change

    Change from baseline Action Research Arm Test immediately after intervention is obtained by subtracting the baseline from the later Action Research Arm Test score.

    Immediately after intervention

  • Motor network construction

    Construct the motor network with the bilateral primary motor cortices, supplementary motor cortices, premotor cortices, thalami and cerebellums et al. as the nodes of the network. Motor network analysis consists the network strength, global efficiency and local efficiency. The software used is PANDA and GRETNA.

    Baseline

  • Motor network change

    Change from baseline motor network immediately after intervention is obtained by subtracting the baseline from the later network strength, global efficiency and local efficiency.

    Immediately after intervention

  • Cerebral perfusion calculation

    The volume of interest covers the motor related territory including bilateral primary motor cortices, supplementary motor cortices, premotor cortices, thalami and cerebellums et al. The mean Cerebral Blood Flow value is calculated. The software used is Function Tool.

    Baseline

  • Cerebral perfusion change

    Change from baseline cerebral perfusion immediately after intervention is obtained by subtracting the baseline from the later Cerebral Blood Flow value.

Study Arms (4)

Control group

NO INTERVENTION

Stroke patients accept the traditional rehabilitation alone.

Transcranial Direct Current Stimulation group

ACTIVE COMPARATOR

Stroke patients accept the Transcranial Direct Current Stimulation alone.

Behavioral: Transcranial Direct Current Stimulation therapy

Motor imagery group

ACTIVE COMPARATOR

Stroke patients do the motor imagery alone.

Behavioral: Motor imagery therapy

Transcranial Direct Current Stimulation and motor imagery group

EXPERIMENTAL

Stroke patients accept the Transcranial Direct Current Stimulation and do the motor imagery at the same time.

Behavioral: Transcranial Direct Current Stimulation and motor imagery therapy

Interventions

Transcranial Direct Current Stimulation with two saline-soaked electrodes (5cm x 7cm) is applied by our occupational therapist. The anode is placed on the ipsilesional primary motor cortex (C3/C4). The cathode is placed on the contralesional shoulder. The current is 1.5 milliampere and lasts 20 minutes.

Transcranial Direct Current Stimulation group

Stroke patients are asked to watch a video about the upper extremity movement. The video lasts 20 minutes. The contents are as follows: the patients are asked to relax the muscles for the first 2 minutes; the action refers to shoulder flexion and extension, elbow flexion and extension, forearm pronation and supination, wrist flexion and extension, finger flexion and extension, and corresponding daily functional activities for 16min; the patients are asked to relax their mind and body for the last 2 minutes.

Motor imagery group

The treatment parameters are the same as the above. It should be emphasized that the participants sit and perform the motor imagery task while receiving Transcranial Direct Current Stimulation.

Masking Details
Because of the different therapies, it is not possible to mask the participant. It was possible to mask the group allocation for routine rehabilitation therapist. However, the difference is obvious between Transcranial Direct Current Stimulation and motor imagery. Outcome measure is conducted by a physician who is blinded to group assignment.
