Abstract: Objective  To explore the effect of problem-based learning (PBL) combined with virtual reality (VR) into neurology clinical teaching on post-stroke sleep disorder. 
Methods  A total of 70 postgraduates who underwent training in the Department of Neurology of the First Hospital of Jilin University from September 2022 to January 2023 were included and randomly divided into the experimental group and the control group, 35 in each group. The control group adopted PBL teaching method, and the experimental group adopted PBL combined with VR teaching method. The teaching content was about the anatomical basis of post-stroke sleep disorder. After the course, two groups were assessed with test papers and questionnaires, and the assessment results were compared. 
Results  Students in the experimental group had higher scores in basic theory (46.03±1.76 vs. 43.69±1.91), case analysis (42.11±2.19 vs. 39.57±2.56) and total score (88.14±2.55 vs. 83.26±3.55)than the control group, and the difference was statistically significant (P<0.001); students in the experimental group had higher evaluations on the role of this course in stimulating motivation (2.63±0.49 vs. 2.11±0.47), improving learning efficiency (2.57±0.50 vs. 1.97±0.57), improving self-learning ability (2.54±0.51 vs. 2.00±0.42) and cultivating clinical thinking (2.51±0.51 vs. 1.94±0.42) than the control group, and the difference was statistically significant (P<0.001).
Conclusions  Application of PBL combined with VR in neurology clinical teaching improves effectiveness of teaching on clinical education of post-stroke sleep disorder.
