Compare Effects of the Mirror Therapy and Robotic Mirror Therapy in Electroencephalography of Healthy Adults and Stroke Patients.

Mirror therapy has recently attracted increasing attention; however, most patients have the difficulties to perform mirror therapy due to limited imaginary ability. A mirror robotic hand system was developed, which consisted with a wearable exoskeletal hand, sensor glove, and a control box. The patient's unaffected hand wears the sensor glove, the affected hand wears the wearable exoskeleton hand, and the unaffected hand does the certain transitive and intransitive tasks as the mirror group, and then makes the affected hand do the same movements driven by the exoskeleton robotic hand. The investigators hypothesize that combining both approaches might facilitate the sensorimotor cortex that controls movement and might augment somatosensory input and further treatment efficacy. This study is aimed at investigating the effects of Mirror therapy and robotic mirror therapy on motor cortical activations in healthy adults and stroke patients using electroencephalography. All participants will perform the conditions of resting, moving right hand with or without robotic hand as the baseline data, then they will do mirror therapy using the right hand as active hand, or wearing robotic hand doing mirror therapy in random sequence. Electroencephalography (EEG) assessment will be done to assess the neurophysiologic effects of the different interventions. The investigators will use a questionnaire to assess the subjective opinion about the different interventions. combined with execution (video AOE). The investigators will use the pair-t test to assess the within subjects differences in EEG and the questionnaire results. This study will be done during 2020/02/01 - 2021/03/31.
