Title: N/A
Brief Summary: The purpose of this study is to investigate the effects of robot-assisted gait training on active walking in the patients with stroke.


Options:
A: Inclusion Criteria:

1. Hemiparesis as result of 1st stroke
2. No other neurologic or orthopedic disorder
3. Independent ambulation before the stroke
4. No severe medical illnesses
5. Hemiparesis: lower extremity strength graded ≤ 3 in more than 2 muscle groups
6. Functional ambulation classification (FAC) ≤ 1 : indicating a need for personal assistance in ambulation
7. The interval between stroke and start of the treatment
8. Time since stroke onset \< 6 months
9. age: 20-80yrs old

Exclusion Criteria:

1. Unstable fractures
2. Severe osteoporosis
3. Severe skin problems
4. Severe joint problems
5. Major difference in leg length,
6. Body weight over 130 kg,
7. Orthostatic circulatory problem
8. Severe cognitive impairment
B: Inclusion Criteria:

* 1st-ever-stroke
* hemiplegic patient after stroke
* who can stand independently, but cannot walk more than 10 meters independently
* whose muscle powers of hip and knee are more than poor on manual muscle test

Exclusion Criteria:

* previous gait difficulty before stroke onset
* arthralgia on lower extremity
* uncontrolled hypertension or hypotension
* severe medical illness
C: 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
D: Inclusion Criteria:

* Ischemic or hemorrhagic stroke \>6 months prior in men or women aged between 18-80 years.
* Clear indications of hemiparetic gait by clinical observation.
* Completed all conventional physical therapy.
* Ability to walk on a treadmill with handrail support.

Exclusion Criteria:

* Cardiac history of (a) unstable angina, (b) recent (less than 3 months) myocardial infarction, congestive heart failure (NYHA category II); (c) hemodynamically significant valvular dysfunction.
* Major clinical depression: CESD score \> 16 and judgment of clinical depression
* Medical History: (a) recent hospitalization (less than 3 months) for severe medical disease, (b) symptomatic peripheral arterial occlusive disease, (c) orthopedic or chronic pain conditions that significantly alter gait function, (d) pulmonary or renal failure (e) active cancer
* History of non-stroke neuromuscular disorder restricting gait.
* Aphasia or cognitive functioning that confounds participation, defined as unable to follow 2 step commands. The Mini Mental State Exam will be administered with a cut-off of less than 23 (less than 17 if education level at or below 8th grade), or judgment of the medical officer.
* Hypertension that is a contraindication for a bout of treadmill training (greater than 160/100 on two assessments).
* Self-report of pregnancy
