Abstract:
ObjectiveTo observe the rule of functional reorganization in stroke patients during early recovery. MethodsFrom April, 2023 to April, 2024, 20 patients with serious left hemiplegia for right cerebral infarction of two to four weeks were included as experimental group, from Beijing Rehabilitation Hospital Affiliated to Capital Medical University; meanwhile, 20 healthy subjects were included as control group. All the subjects finished a block designed left elbow flexing task, and were measured with functional near-infrared spectroscopy. The control group finished the test once; and the experimental group finished the test once per two weeks, for five times, and laterality indexes were calculated; they were also assessed with Fugl-Meyer Assessment-Upper Extremity (FMA-UE) before each test. ResultsThe score of FMA-UE increased time by time (P < 0.05). For the experimental group, laterality index showed that the activation shifted from right dominance to balance in the whole brain, primary motor cortex and supplementary motor area; and it shifted from balance to right dominance in dorsolateral prefrontal cortex, and form right dominance to left dominance in premotor cortex. ConclusionAt the early recovery stage of stroke patients, the upper limb motor function is gradually improving, with the activation in most motor cortex shifting from affected hemisphere dominance to bilateral hemisphere balance; however, the activation may become affected or unaffected dominance in some brain areas.
