简要总结
The purpose of this study is to evaluate a new virtual reality (VR)-based rehabilitation program designed to help stroke survivors improve their walking abilities in real-world settings. By comparing immersive VR-assisted overground gait therapy to contemporary non-immersive, treadmill-based VR therapy (i.e., C-Mill), the investigators aim to determine its effectiveness in enhancing mobility and quality of life for stroke survivors.
详细描述
After obtaining consent and screening, eligible participants are randomized to the treatment or control groups.
First, all participants are issued a wearable tracker to gauge baseline activity for at least 5 days.
During the intervention phase, participants undergo 12 treatment sessions, 2x a week for 6 weeks.
Assessments are conducted at pre-intervention, post-intervention, and 1-month followup.

入选标准
- •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.
排除标准
- •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.
研究组 & 干预措施
Conventional Treadmill-Based VR Gait Therapy
Participants in the control group (VR-CTGT) will engage in gait training using C-Mill VR+ technology, which involves treadmill-assisted walking on a treadmill while interacting with less immersive virtual scenarios presented on screens.
干预措施: C-Mill VR+ by Motek (Device)
VR-Assisted Overground Gait Therapy
Participants in the treatment group (VG-AOGT) will engage in gait training within a newly developed immersive virtual reality (VR) environment. This setup features self-propelled overground walking influenced by three different virtual environments designed to mimic real-world conditions. The immersive technology used is HTC VIVE Focus Vision, enabling participants to practice walking in real-world environments and gait tasks.
干预措施: Walk-over-Ground (Device)
结局指标
主要结局
Step Count
时间窗: Continuous tracking from Screening to Week 10
FitBit tracks the number of steps (count) taken by participant.
Travel Distance
时间窗: Continuous tracking from Screening to Week 10
FitBit tracks the total distance (miles) travelled by participant.
Activity Zone Minutes
时间窗: Continuous tracking from Screening to Week 10
Fitbit calculates maximum heart rate (HR) from user age (Max HR = 220 - age) and defines Activity Zone thresholds based on percentages of max HR (Fat Burn 50-69%, Cardio/Peak \>70%). Activity Zone Minutes (AZMs) are an intensity-weighted measure of activity. AZM (count) is based on sustained heart rate over time: 1 AZM per minute in the Fat Burn Zone (50-69% max HR) and 2 AZMs per minute in the Cardio/Peak Zones (\>=70% max HR).
