Résumé
Based on Monte Carlo algorithm and multimodal MRI diagnosis, the effect of motor learning on motor memory function recovery in stroke patients was investigated in this research. A total of 26 stroke patients with hemiplegia treated in hospital in the past three years were recruited. Patients were rolled into routine group (13 cases) and experimental group (13 cases) according to different follow-up rehabilitation methods. All patients were treated with intravenous thrombolysis. After treatment, the conventional group received conventional rehabilitation therapy and the experimental group received restraint induced exercise therapy (CIMT). Then, T1-weighted imaging, T2-weighted imaging, 3D anatomical imaging, and resting state examinations were performed on the patients before and after treatment. All image data and image processing were performed by the Monte Carlo algorithm. Before treatment and six weeks after rehabilitation treatment, the patients’ mental state and memory function were tested using Addenbrooke’s Cognitive Examination (ACE-III) and Montreal Cognitive Assessment (MoCA). In addition, the Fugl-Meyer motor assessment, the simple test for evaluating hand function, and the modified Barthel index were used to evaluate the patient’s ability of daily living. After processing, the quality of multimode MRI image was improved obviously, and the lesion was more prominent. The fractional amplitude of low frequency fluctuation of supplement motor area in stroke patients increased after treatment combined with exercise rehabilitation ( <math xmlns="http://www.w3.org/1998/Math/MathML" id="M1"> <mi>P</mi> <mo><</mo> <mn>0.05</mn> </math> ) and ReHo decreased compared with that before treatment. The connection function of the left and right hippocampus was enhanced. The difference in ACE-III (experimental group: 16 versus 21; control group: 17.1 versus 19) scores between the two groups after treatment and before treatment was remarkable ( <math xmlns="http://www.w3.org/1998/Math/MathML" id="M2"> <mi>P</mi> <mo><</mo> <mn>0.05</mn> </math> ), but the score of patients in experimental group improved better. The MoCA (experimental group: 24.38 versus 26.47; control group: 23.13 versus 23.37) scores of the two groups of patients changed greatly from those before treatment ( <math xmlns="http://www.w3.org/1998/Math/MathML" id="M3"> <mi>P</mi> <mo><</mo> <mn>0.05</mn> </math> ), and the MoCA score ratio between the two groups was also statistically different (26.47 versus 23.37; <math xmlns="http://www.w3.org/1998/Math/MathML" id="M4"> <mi>P</mi> <mo><</mo> <mn>0.05</mn> </math> ). There was a statistical difference in the living ability of the two groups of patients before and after treatment ( <math xmlns="http://www.w3.org/1998/Math/MathML" id="M5"> <mi>P</mi> <mo><</mo> <mn>0.05</mn> </math> ). The Monte Carlo algorithm had a good processing effect on multimodal MRI images. The recovery of the experimental group was evidently better, and the difference between the two groups was substantial ( <math xmlns="http://www.w3.org/1998/Math/MathML" id="M6"> <mi>P</mi> <mo><</mo> <mn>0.05</mn> </math> ). CIMT had a good effect on the recovery of exercise rehabilitation and memory function of patients with ischemic stroke.
