Feasibility of Using Immersive Virtual Functional Rehabilitation for Recovery of Upper Extremity Function in Patients With Early-stage Stroke: a Pilot Study
Feasibility of using immersive virtual functional rehabilitation for recovery of upper extremity function in patients with early-stage stroke: a pilot study
Background: Immersive virtual reality (IVR)-based rehabilitation provides high-intensity, engaging, task-oriented training and motor exploration for upper limb (UL) recovery post-stroke. However, its feasibility and dose-response effects remain unclear.
Objective: To evaluate the feasibility and dose-response effects of IVR-based rehabilitation for UL recovery in early stroke patients.
Methods: A pilot trial included 12 early-stage stroke patients randomized into two groups: Group A (10 IVR sessions + conventional rehabilitation [CR]) and Group B (20 IVR sessions + CR). Feasibility outcomes included adherence, usability (User Satisfaction Evaluation Questionnaire [USEQ], System Usability Scale [SUS]), system operability, and adverse effects. Motor outcomes, categorized by the International Classification of Functioning, Disability, and Health (ICF), assessed UL impairment (Fugl-Meyer Assessment, Medical Research Council scale), activity (Box and Block Test), and participation (Motor Activity Log 30). Blinded therapists conducted assessments at baseline, post-intervention, and 4-week follow-up. Dose-response was analyzed using Probability of Superiority (PS).
