| Objective: To explore the effect of transcranial direct current stimulation on upper limb dysfunction in stroke based on the bimodal balance-recovery model. Methods: A total of 40 patients were randomly divided into experimental group (n=20) and control group (n=20). The experimental group was treated with transcranial direct current stimulation + conventional rehabilitation based on bimodal balance-recovery model theory, and the control group was treated with transcranial direct current stimulation + conventional rehabilitation based on interhemispheric competition model theory. The rehabilitation effect was observed for 4 weeks, 5 days a week, for a total of 20 treatments. Each patient was assessed before and after treatment, including modified Ashworth Spasticity Rating Scale, Fugl-Meyer Upper Limb Motor Function Rating Scale, modified Barthel Index Rating Scale, and Motor Activity Recording Scale. Results： After treatment, the upper limb function of the two groups was significantly improved. After treatment, the UEFM score in the upper limb in the experimental group was significantly higher than that in the control group (P<0.05). The improvement of MAS of the shoulder joint and elbow joint in the experimental group was significantly better than that in the control group (P<0.05). After treatment, the activities of daily living of the two groups were significantly improved, and the scores of MBI and MAL in the experimental group were better than those in the control group after treatment (P<0.05). Conclusion：Transcranial direct current stimulation based on the bimodal balance-recovery model neuromodulation strategy significantly improves upper limb function in stroke patients. |
