* Willing to carry wireless body sensors through the period of the study and to follow-up time period, post inpatient stroke, cardiac, pulmonary, or any other lower extremity physical rehabilitation
* ≥ 90 days post major orthopedic surgery (i.e. hip, knee, and/or ankle joint replacement)
* ≥ 6 months post coronary artery bypass grafting (CABG) or cardiac valve procedure
* Able and willing to give written consent and comply with study procedures, including follow-up visits
* Cannot not be participating in any other structured outpatient or home health physical therapy program

Exclusion Criteria:

* Serious cardiac conditions (hospitalization for myocardial infarction or heart surgery within 3 months, history of congestive heart failure, documented serious and unstable cardiac arrhythmias, hypertrophic cardiomyopathy, severe aortic stenosis, angina or dyspnea at rest or during activities of daily living)

* History of concussion in last 6 months
* Subject is pregnant, nursing or planning a pregnancy
* Inability to travel 3 times per week for outpatient training programs
* Participating in another clinical trial that, according to the Principal Investigator, is likely to affect study outcome or confound results
C: Inclusion Criteria:

* Patients with infratentorial stroke
* Cognitively intact enough to understand and follow the instructions from the investigator

Exclusion Criteria:

* chronic neurological pathology
* orthopedic injuries
* femur lengths of less than 34cm
* severely limited range of lower extremity joint motion
* medical instability
D: Inclusion Criteria:

1. Ischemic or hemorrphagic stroke with drop foot problem.
2. Sufficient cognition to follow simple instructions and to understand the content and purpose of the study. (Mini-Mental State Examination \> 21)
3. Capable of standing and walking independently for an extended period of time. (Functional Ambulation Category \> 3, Berg Balance Scale \> 40)

Exclusion Criteria:

1. Any medical or psychological dysfunctions that would affect their ability to comply with test study protocol, such as lower back pain, neuralgia, rotational vertigo, muscloskeletal disorders, injuries, and pregnancy.
2. Any severe contractures in hip, knee, or ankle joint that would preclude passive range of motion in the lower extremity.
3. Participation in any therapeutic treatment ("outside therapy") performed with the lower extremity during the planned study, including the baseline and the follow-up.
