Methods	RCT
Participants	Study took place in Korea 10 participants: 5 intervention, 5 control Inclusion criteria: ≥ 1 year after first stroke, plateau in the maximum motor recovery after conventional neurorehabilitation, > 60 degrees extension at the knee Exclusion criteria: severe spasticity (modified Ashworth scale > 2) or tremor, severe visual and cognitive impairment Mean age: intervention group 55 years, control group 55 years 70% male Stroke details: 30% right hemiparesis Timing post stroke: intervention group 18 months, control group 19 months
Interventions	Virtual reality intervention: IREX virtual reality system using a video capture system to capture the participant's whole body movement. The participant is able to view their body movements in real time on a screen in front of them immersed in a virtual environment. Games included stepping up/down, 'shark bait' and snowboarding Control intervention: no intervention provided Sessions for the virtual reality group were 60 minutes, 5 times a week for 4 weeks (20 hours total)
Outcomes	Outcomes recorded at baseline and post‐intervention Lower limb function and activity outcomes: Functional Ambulation Category Global motor function: modified Motor Assessment Scale Imaging studies: functional MRI ‐ laterality index
