Abstract Objective: To explore the effect of VR/AR rehabilitation training combined with conventional rehabilitation therapy on upper limb functional rehabilitation and daily living ability of patients with early cerebral infarction, to reconstruct corticospinal tract (CST) using diffusion tensor imaging (DTI) technology, and to study the correlation between the number of nerve fibers in CST and motor function recovery. Methods: Twenty patientswere randomly divided into two groups, given conventional drugs and rehabilitation treatment, with the experimental group given VR combined with AR rehabilitation training. The upper Brunnstrom staging scale, upper limb Fugl-Meyer assessment for upper extremity (FMA-UE) system and modified Barthel index (MBI) were used to evaluate the two groups before and after the treatment. Cranial DTI of the two groups were reconstructed and the number of nerve fibers in CST was calculated. The increase and decrease of nerve fiber number before and after treatment were compared and their correlation with FMA-UE score was discussed. Results: Before the treatment, there was no significant difference between the two groups (P>0.05) in scale scores and the number of nerve fibers in the affected CST; after 3 weeks of treatment, the above indexes of the two groups increased significantly (P<0.05) compared with those before. And the experimental group had higher FMA-UE and Brunnstrom staging score of the upper limbs and hands than the control group, with significant difference (P<0.05); There was no significant difference in MBI scores between the two groups (P>0.05). The difference in MBI and FMA-UE scores between the two groups was statistically significant after treatment (P<0.05), but there was no significant difference (P>0.05) in the number of CST side nerve fiber between the experimental group and the control group. The number of nerve fibers in the affected CST was positively correlated with the FMA-UE score of the upper limb before and after rehabilitation. Conclusion: VR/AR rehabilitation therapy combined with routine rehabilitation training can significantly improve the upper limb motor ability of hemiplegia patients with early cerebral infarction, and can promote cerebral nerve fiber recombination and improve CST compensation.DTI technology can be used to analyze the changes in motor ability of patients with early cerebral infarction.
