Title: The Effects of Functional Strength Training on Weakness and Function of the Lower Limb After Stroke
Brief Summary: The purpose of this study is to test the hypothesis that adding functional strength training to UK conventional therapy improves muscle function and walking than either UK conventional therapy alone or increased intensity of UK conventional therapy


Options:
A: Inclusion Criteria:

Subjects in this study will:

* be aged over 50 years.
* be between one week and three months after stroke when recruited to the study;
* have been independently mobile indoors, with or without aids, before the stroke;
* have some voluntary movement in the paretic lower limb i.e. score above 28/100 on the lower limb section of the Motricity Index43;
* demonstrate adequate orientation and communication (be able to complete a one-stage command using the non-paretic upper limb e.g. point at the ceiling).

In addition those who agree to participate in TMS measurement will have no contraindications to TMS.
B: Inclusion Criteria:

* Post stroke survivors of single unilateral stroke
* discharged from rehabilitation
* the ability to walk independently, with or without using an aid or orthosis
* sufficient cognitive ability,
* the ability to comprehend instruction

Exclusion Criteria:

* history of serious cardiac disease (e.g. myocardial infarction, unstable angina)
* uncontrolled blood pressure
* significant neurological or musculoskeletal conditions in addition to stroke
C: Inclusion Criteria:

* subacute (\<6 months) stroke
* 18-75 years old
* history of history of unilateral, supratentorial, ischemic or hemorrhage stroke
* able to walk 10m without physical assistance
* gait speed less than or equal to .8m/s
* medical clearance

Exclusion Criteria:

* significant cardiorespiratory or metabolic disease that may limit exercise participation
* weight limit \> 250 lbs (limit of most counter-weight safety systems)
* history of previous orthopedic or neurological conditions which may impair walking.
* women of childbearing potential will not be excluded, although women who are pregnant will be excluded due to potential forces at trunk from the harness applied at the waist.
* subjects with scores \< 23 on the Mini Mental Status Exam

  * Exclusion for transcranial magnetic stimulation (TMS):
* pacemaker
* metal implants in the head region
* history of epilepsy or seizures
* skull fractures or skull deficits
* concussion within the last 6 months
* unexplained recurring headaches
* medications that lower seizure threshold
* pregnancy

  * Exclusion for the MRI:
* aneurysm clip or coil
* metal or wire implants
* heart valve prosthesis
D: Inclusion Criteria:

* Patients with more than 6 months post stroke,
* Muscular control greater than or equal to 3 on the extensors and elbow flexors,
* Muscular control greater than or equal to 3 on the flexors and extensors of the wrist,
* Spasticity less than or equal to 3 on the muscle groups mentioned above, s
* Active abduction of the shoulder above 60 ° and painless
* Absence of cognitive impairment (MMS\> 22 without any trouble phasic)
* No orthopedic limitations at the elbow and wrist,

Exclusion Criteria:

* Progressive neurological or systemic involvement,
* Orthopedic limitations at the elbow or wrist
* Cognitive,
* Hemineglect,
* Severe aphasia with impaired comprehension,
