In order to explore the immediate effect of passive motion in patients with hemiplegia based on brain functional magnetic resonance imaging (fMRI), a total of 100 patients, who were diagnosed as stroke hemiplegia and underwent fMRI examination at a hospital designated by this study from December 2016 to December 2018, were chose as study subjects and were divided into observation group and control group according to the random number table method with 50 cases of patients in each group. The fMRI examinations were performed in the 2 groups of patients within 1 week after treatment; 10 voxels were taken as effective activating voxels to obtain statistical parameter maps for region of interest analysis; and bilateral cerebral hemispheres, sensorimotor cortex and supplementary motor area were selected as the region of interest to calculate the number of activated voxels respectively; the clinical neurological deficit scale, simplified motor function scale, and functional independence assessment table are used for the evaluation of the 2 groups of patients at the beginning and after 8 weeks of treatment. The results show that all patients’ fMRI examinations are characterized by motor function area cerebral infarction or corresponding corticospinal tract cerebral infarction; the healthy side finger movement function area is basically normal in the brain function imaging examination; the cortical signal regions are concentrated in the vicinity of the central frontal first motion zone and the central posterior proprioception zone with strong repeatability when the active, passive and resistance-inducing active movements are respectively performed on the healthy side; and the contralateral sensorimotor cortex and bilateral auxiliary exercise areas were activated. The hemiplegia patients had increased activation of the hemisphere during hand movement, and the fMRI results were basically the same as those of the normal subjects. Therefore, the fMRI examination can provide imaging data for cortical functional zone localization of active and passive movements of the fingers, and provide assistance for clinical rehabilitation and prognosis assessment. The results of this study provide a reference for further researches on the immediate effects of passive motion in patients with hemiplegia based on brain functional magnetic resonance imaging.
