Overground Virtual Reality (VR) Gait Rehabilitation for Stroke

Inclusion Criteria: * Diagnosis: Anischemic or hemorrhagic stroke verified by imaging, confirmed by the patient's physician, and 1-6 months post-stroke (subacute phase) * Motor Impairment Level: Functional Ambulation Category (FAC) 3-5, showing moderate impairment while still allowing safe participation in gait tasks. * Cognitive Function: Mini-Mental State Examination (MMSE) score ≥ 24 or Montreal Cognitive Assessment (MoCA) score \>= 20, indicating sufficient cognitive function to participate in the study. * Exercise Clearance: Approval from a physician for participation in exercise- and VR-based interventions. * Rehabilitation Need: 10-Meter Walk Test \<1.0 m/s, as timed by a PT during screening, indicating a need for functional rehabilitation. * Consent: Must be able to provide informed consent for themselves. Exclusion Criteria: * Participants with uncontrolled cardiovascular, orthopedic, or metabolic conditions or unstable medication regimens that could interfere with their participation in the study. * Any comorbidity that could interfere with walking or gait training. * Participation in robot- or VR-assisted gait training within the last 6 months. * Intolerance to virtual reality environments or motion simulation. * Severe cognitive, visual, or hearing impairments where the participant cannot follow the therapist's instructions. * Any other condition deemed unsafe or confounding by investigator, such as pre-existing neurological conditions unrelated to stroke (e.g. Parkinson's, multiple sclerosis), unmanaged pain medications, or acute medical events during the screening period (e.g. recurrent stroke, hospitalization). * Individuals who score a 12 or higher on the Disability Rating Scale. * Recent Therapy: Participants should not have received physical therapy (PT) within the last month.
