Objective To investigate the eff ect of virtual reality training on unilateral spatial neglect in stroke patients. Method Twenty-four stroke patients (14 males and 10 females, mean age=64.7) who had unilateral spatial neglect as a result of right hemisphere stroke were recruited. All patients were randomly assigned to either the virtual reality (VR) group (n=12) or the control group (n=12). Th e VR group received VR training, which stimulated the left side of their bodies. Th e control group received conventional neglect therapy such as visual scanning training. Both groups received therapy for 30 minutes a day, fi ve days per week for three weeks. Outcome measurements included star cancellation test, line bisection test, Catherine Bergego scale (CBS), and the Korean version of modifi ed Barthel index (K-MBI). Th ese measurements were taken before and after treatment. Results There were no significant differences in the baseline characteristics and initial values between the two groups. Th e changes in star cancellation test results and CBS in the VR group were signifi cantly higher than those of the control group after treatment. Th e changes in line bisection test score and the K-MBI in the VR group were not statistically signifi cant. Conclusion Th is study suggests that virtual reality training may be a benefi cial therapeutic technique on unilateral spatial neglect in stroke patients.
