Title: The Efficacy of Treadmill Training in Establishing Walking After Stroke
Brief Summary: Being able to walk is a major determinant of whether a patient returns home after stroke or lives in residential care. For the family, the loss of the stroke sufferer from everyday life is a catastrophic event. For the community, the costs of being unable to walk after stroke are exorbitant, involving a lifetime of residential care. Therefore, an increase in the proportion of stroke patients who regain walking ability will be a significant advance.

This trial will determine, in patients early after stroke who are unable to walk, whether training walking using a treadmill with partial weight support via an overhead harness will be more effective than current intervention in (i) establishing more independent walking, reducing the time taken to achieve independent walking, and improving the quality of independent walking, and (ii) improving walking capacity and participation 6 months later.

* Unable to travel 3 times per week for outpatient training programs
* Intracranial hemorrhage related to aneurysmal rupture or an arteriovenous malformation (hemorrhagic infarctions will not be excluded)

Inclusion and exclusion criteria will be determined by a chart review, depression screen and subject interview by study physician or study coordinator. After initial chart and subject interview, each subject's treating physician will be asked to review inclusion and exclusion criteria and provide a letter supporting inclusion in the study. All subjects who meet selection criteria must successfully complete an exercise tolerance test
B: Inclusion Criteria:

Exclusion Criteria:

* Any barriers to taking part in a physical rehabilitation program
* Insufficient cognition/language
* Unstable cardiac status
* Neuro-surgery
* Any pre-morbid history of orthopaedic conditions or any other problems that would preclude patient from relearning to walk.
C: Study population: Subjects with a diagnosis of stroke

Inclusion Criteria:

* first stroke (\<6 months ago)
* presence of hemiparesis in the lower extremity
* minimum Berg Balance Score (BBS) of 30/56

Exclusion Criteria:

* bilateral stroke, or a previous stroke in the other hemisphere
* severe co-morbidity that is likely to dominate the pattern of care
* co-existing peripheral neuropathies or disorders of the vestibular apparatus
* musculoskeletal problems

D: Inclusion Criteria:

* Subjects aged 40 years or older.
* Patients with a clinical diagnosis of stroke; symptoms lasting 24 hours or more.

Exclusion Criteria:

* Patients who are unable to understand the information, or who cannot cooperate, are excluded.
* Patients confined to a wheelchair or bed.
* CT-scanning showing intracranial haemorrhage or focal pathology other than infarction, cerebral atrophy, or leucoaraiosis.
* Modified Rankin score of 4 or 5 before the actual stroke.
* Serious medical disease such as AIDS, metastatic cancer, or abnormalities that the investigator feels may compromise the patient's successful participation in the trial.
