Evaluation of Motor Function Rehabilitation for Stroke Patients Based on Magnetic Resonance DTI Technology

Based on functional imaging methods of resting state DTI (Diffusion tensor imaging), this study reveals the structural changes and functional abnormalities of white matter fibers in patients with stroke from two levels of structure and function, and analyzes the effects of exercise on brain function remodeling in patients with stroke. The effects of the process, explore the central effect mechanism of scalp acupuncture to promote the recovery of motor function, and provide ideas for optimizing the rehabilitation treatment after stroke. There was no statistically significant difference in the general situation of the motion observation group and the conventional rehabilitation treatment group based on DTI technology at the time of enrollment, the NIHS S score, the fugl-meyerassessmenta score, the modified ashworth scale score, and the Brunnstrom staging assessment (P>0.05). After the week, 8 weeks, and 12 weeks of follow-up, the national institutes of health stroke scale, fugl-meyerassessmenta score, modified ashworth scale score, and Brunnstrom motor function staging score of the two groups of patients were significantly improved over time before treatment. The difference was statistically significant (P>0.05); the comparison between groups, the scores of patients in the action observation group and the difference before and after treatment were significantly higher than those in the conventional rehabilitation treatment group, and the difference was statistically significant (P>0.05). Conclusion: Action observation therapy can improve the degree of neurological deficits and promote the recovery of neurological function in patients with stroke. It can improve the score of motor function, reduce the muscle tension of key muscles in patients with stroke, and promote the recovery of motor function in patients.
