No results posted yet for this study

Summary

The aim of this study is to investigate the effects of intermittent theta burst stimulation primed with continous theta burst stimulation (cTBS), on top of a standard robot-assisted training (RAT) on improving the upper limb motor functions of stroke survivors and to explore potential sensorimotor neuroplasticity with electroencephalography (EEG).

DEVICE

Theta burst stimulation (TBS)

Theta burst stimulation (TBS) is a potent form of repetitive transcranial magnetic stimulation (rTMS). Standard 600-pulse intermittent theta burst stimulation (iTBS) can enhance the corticomotor excitability, whereas standard 600-pulse continuous theta burst stimulation (cTBS) can suppress the corticomotor excitability. Sham stimulation uses an extreme low stimulation intensity which will not influence with corticomotor excitability. In the present study, real stimulation will be delivered in an intensity of 70% individual resting motor threshold while sham stimulation will be delivered in an intensity of 20% individual resting motor threshold.

BEHAVIORAL

Robot-assisted training

Fourier M2 upper limb rehabilitation robot (Fourier Intelligence Co. Ltd., Shanghai, China), will be used for upper limb proximal joints training. Fourier M2 upper limb rehab robot is an end-effector robot-assisted device. The device targets (1) flexion and extension of shoulder joint, (2) flexion and extension of elbow, (3) internal and external rotation of shoulder joint, and (4) abduction and adduction of shoulder joint, supported by tailored interactive TV games in the device. HandyRehab hand robot (Zunosaki Company Ltd., Hong Kong SAR) will be used for upper limb distal joints training. It is an exoskeleton over the hand which provides power-driven extension and grasping force to the fingers and thumb in order to assist the patient to open and close the paretic hand by means of surface electromyography-triggered from the signals through the forearm extensors and flexors.
