Title: Comparative Efficacy Research of Uni- vs Bi-lateral Arm Training Poststroke: Task-Related or Robotic
Brief Summary: This proposed project aims to

* compare the effects of dose-matched unilateral vs bilateral vs unilateral combined with bilateral upper limb rehabilitation based on task-related practice
* compare the effects of unilateral vs bilateral training based on robot-assisted devices
* study the predictors of treatment outcomes and clinimetric properties of the biomechanical measures


Options:
A: Inclusion Criteria:

* 40 to 75 years old
* 6 to 24 months after stroke onset from a first-ever unilateral stroke
* An initial 26 to 56 scores on the UE subsection of the
* Premorbid right-hand dominance evaluated by the Edinburgh Handedness Inventory
* No excessive spasticity in the shoulder and elbow joints of the affected UE (Modified Ashworth Scale score ≤ 3 in each joint)
* Sufficient cognitive ability, defined as a score of more than 24 on the Mini Mental State Examination

Exclusion Criteria:

* Physician-determined major medical problems or poor physical condition that would interfere with participation
* Excessive pain in any joint that might limit participation
B: Inclusion Criteria:

* Over 21 years of age, weakness due to a recent stroke or other brain injury, and receiving rehabilitation. Subjects are inpatients at one of the participating VA hospitals.

Exclusion Criteria:

Unable to follow instructions; medically unstable.
C: Inclusion Criteria:

1. recent unilateral single stroke (ischemic or hemorrhagic) verified by brain CT or MRI;
2. sufficient cognitive and language skills to understand the instructions of the operator (assessed by Modified Mini-Mental State Examination \> 21);
3. patients with upper limb paralysis (Motor Power score between 8 and 12);
4. written informed consent signed by the patient (or an authorized representative).

Exclusion Criteria:

1. cardiovascular instability (severe uncontrolled hypertension, severe coronary artery disease, etc.) or orthopedic, or neurological conditions;
2. presence of multiple cerebrovascular lesions (usually the result of many ischemic episodes in the past);
3. early appearance of marked spasticity (≥ 3 according to Ashworth Scale);
4. joint pain or limited joint range of motion (ROM) of the upper limb that results in the inability to complete the protocol;
5. severe neuropsychologic impairment (global aphasia, severe attention deficit or neglect), affecting the patient's ability to follow instructions;
D: Inclusion Criteria:

* 6 months onset from a first-ever unilateral stroke
* An initial UL subsection of the Fugl-Meyer Assessment score of 20 to 50 indicating moderate and moderate to severe UL movement impairment
* No balance problems sufficient to compromise safety when wearing the study's constraint device
* No excessive spasticity in any of the joints of the affected UL (modified Ashworth scale ≤ 3)
* Without upper limb fracture within 3 months
* Be able to follow study instructions and perform study tasks (Mini Mental State Examination ≥ 24)
* Willing to provide written informed consent

Exclusion Criteria:

* Exhibit physician-determined major medical problems or poor physical conditions that would interfere with participation
* Excessive pain in any joint that might limit participation
