Title: Functional Recovery in Stroke Patients With Task-Specific Robot-Aided Arm Therapy
Brief Summary: The goal of this study is to determine whether task-oriented, robot-aided therapy is more effective than conventional physical and occupational therapy at promoting functional recovery of the affected arm in chronic hemiparetic stroke patients.


Options:
A: Inclusion Criteria:

* Age 18 or more
* first-ever stroke (hemorrhagic or ischemic), verified by brain imaging
* stroke more than six months prior to the study
* termination of conventional therapy and stable recovery stage (outpatients)
* moderate to severe motor impairment of the arm (upper limb portion of FMA score between 8 and 38)
* ability to sit in a chair without any additional support and without leaning on the back rest
* written informed consent signed by the subject (or an authorized representative)

Exclusion Criteria:

* Excessive spasticity of the affected arm (mAS ≥ 3)
* any serious medical or psychiatric illness
* participation in any clinical investigation within 4 weeks prior to the start of this study
* anticipated need for any major surgery during the study
* women known to be pregnant or lactating
* Orthopedic, rheumatologic or other disease restricting movements of the paralyzed upper extremity
* shoulder subluxation (palpatory \> 2 fingers)
* diseased or damaged skin at the paralyzed arm
* inability to communicate effectively with the neurological examiner such that the validity of the patient's data could be compromised
* cyber sickness
* pace-maker or other implanted electric devices
* body weight \> 120kg
* serious cognitive deficits and aphasia preventing the performance of the ARMin treatment
* participation in any therapeutic treatment ("outside therapy") performed with the paralyzed arm during the planned study - including baseline and follow up.
B: 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;
C: Inclusion Criteria:

* Hemiplegic stroke patients
* Medical research council scale \>= 2 of finger or wrist flexor/extensor
* Medical research council scale \>= 2 of elbow pronation/supination

Exclusion Criteria:

* Bilateral weakness of upper extremities
* Uncontrolled medical or surgical illness
* Predisposing psychological or neurological disorders
* Severe aphasia unable to communicate
* Severe cognitive impairment not to cooperate
* Severe pain impeding upper extremity rehabilitation
D: Inclusion Criteria:

* Unilateral ischemic or hemorrhagic stroke
* within 6 months of admission to in-patient rehabilitation
* Persistent hemiparesis
* Proximal Upper Extremity voluntary activity
* Preserved cognitive function
* Difficult access to an organized stroke rehabilitation program

Exclusion Criteria:

* Not independent before stroke
* Hemispatial neglect
* Significant other illnesses
