The goal of this study is to determine robotic hand system is more effective than conventional physical and occupational therapy at promoting functional recovery of the affected arm in subjects after stroke.
This study will investigate the recovery in hand and upper limb functions when the physical training is assisted by an exoskeleton robotic hand system. Subjects with a pure unilateral motor paresis after a stroke (ischemic or hemorrhagic). All subjects should have sufficient cognition to follow simple instructions as well as understand the content and purpose of the experiment, and also should be able to sit up for 1 hour. During the training, you will be asked to do the hand open and hand grasp by Electromyography-driven robotic control strategy. There will be evaluations on the upper limb motor functions before and after the 20-session of training and follow up session by clinical assessments on functional recovery.

Fugl-Meyer Assessment
Evaluate the change from baseline assessment at the end of intervention and monitor the continuous change at three months and six months. Baseline assessment will be conducted at within one week prior to intervention. Participants will be followed for the duration of hospital stay, an expected average of 5 weeks for the 20-session intervention. The assessment at the end of intervention will be conducted within one week after the intervention. The other two assessments will be conducted at three months and six months after the last session of the intervention.
Time frame: Change from baseline Fugl-Meyer Assessment at the end of intervention, at three months and at six months
Action Research Arm Test
Evaluate the change from baseline test at the end of intervention and monitor the continuous change at three months and six months. Baseline test will be conducted at within one week prior to intervention. Participants will be followed for the duration of hospital stay, an expected average of 5 weeks for the 20-session intervention. The assessment at the end of intervention will be conducted within one week after the intervention. The other two assessments will be conducted at three months and six months after the last session of the intervention.

Wolf Motor Function Test
Evaluate the change from baseline test at the end of intervention and monitor the continuous change at three months and six months. Baseline test will be conducted at within one week prior to intervention. Participants will be followed for the duration of hospital stay, an expected average of 5 weeks for the 20-session intervention. The assessment at the end of intervention will be conducted within one week after the intervention. The other two assessments will be conducted at three months and six months after the last session of the intervention.

modified Ashworth Scale
Evaluate the change from baseline test at the end of intervention and monitor the continuous change at three months and six months. Baseline test will be conducted at within one week prior to intervention. Participants will be followed for the duration of hospital stay, an expected average of 5 weeks for the 20-session intervention. The assessment at the end of intervention will be conducted within one week after the intervention. The other two assessments will be conducted at three months and six months after the last session of the intervention.
