There were eight patients in each group. <\/jats:p><jats:p> Main measures: Mini-Mental Status Examination, Motor-free Visual Perception Test and Modified Barthel Index were assessed at the beginning and end of the training. A survey was conducted to evaluate the degree of patients' interest using an interest scale. <\/jats:p><jats:p> Results: After training, the mean (SD) Motor-free Visual Perception Test score increased significantly in both experimental group (from 65.8 (19.5) to 77.8 (28.7)) and control group (from 68.3 (11.4) to 74.1 (14.8)) (P&lt;0.01). Modified Barthel Index score increased significantly in both groups, with the experimental group recording a higher increase. Mean (SD) interest scale score was greater in the experimental group (2.2 (0.8)) than in the control group (1.3 (0.7)) (P&lt;0.01). <\/jats:p><jats:p> Conclusions: A computerized visual perception rehabilitation programme with interactive computer interface using motion tracking technology could be considered as a treatment option for stroke patients with visual perception impairment.
