| Objective: To explore the application of visual stimulation training in patients with severe cognitive impairment after stroke. Methods: Totally, 60 patients with severe post-stroke cognitive impairment were randomly divided into 30 cases in the control group and 30 cases in the study group, and both groups were treated with medication and conventional rehabilitation training. The patients in the study group were given 4 weeks of visual stimulation training, additionally. Before and after the intervention, cognitive function was assessed by the MMSE, visual perceptual ability was assessed by the test of visual perception 3 (TVPS-3) and the visual perception subtest (VPT), and the ability to perform activities of daily living was assessed by the modified Barthel index (MBI) in the control and study groups. Results: After 4 weeks of treatment, MMSE, VPT, the 7 domains of TVPS-3 and MBI scores in the 2 groups were increased as compared with the pre-treatment scores (P<0.01), and MMSE, VPT, MBI, the scores of DIS, MEM and SEQ in theTVPS-3 of the study group were higher than those of the control group (P<0.05，0.01), and there was a positive correlation between the MMSE and VPT scores of the study group (rs=0.76,P<0.01). Conclusion: Visual stimulation training can effectively improve the cognitive function, visual perception ability and activities of daily living of patients with severe cognitive impairment after stroke, and there was a significantly positive correlation between visual perception ability and cognitive function. |
