Effects of Different Doses of Virtual Reality Therapy in Chronic Stroke Patients

This study aimed to compare the effects of different doses of Wii Fit-based virtual reality (VR) therapy added to conventional rehabilitation in patients with chronic stroke. Forty-three patients were randomly assigned to three groups: a control group receiving conventional rehabilitation only (5 days/week, 45 min/session for 4 weeks), a VR3 group receiving conventional rehabilitation plus VR training three days per week (20 min/session, 12 sessions total), and a VR5 group receiving conventional rehabilitation plus VR training five days per week (20 min/session, 20 sessions total). Balance (Berg Balance Scale), functional independence (Functional Independence Measure), stroke-specific quality of life (SS-QOL), static postural alignment (Becure Posture Mobile), and center of pressure measurements (Becure Balance System) were assessed before treatment (T0), after treatment (T1), and at one-month follow-up (T2). This prospective, single-blind, randomized controlled trial was conducted at Istanbul Physical Medicine Rehabilitation Training and Research Hospital.
