Objective To investigate the effects of transcranial direct current stimulation (tDCS) combined with virtual reality (VR) on upper limb dysfunction of stroke patients.Methods Patients with stroke who were hospitalized in the Department of Rehabilitation Medicine, the Third Affiliated Hospital of Sun Yat-Sen University from July 2018 to January 2020 were selected. The patients were divided into tDCS group, VR group and combined treatment group by random number table method. All three groups received conventional rehabilitation treatment. Based on this, tDCS group received 2.0 mA tDCS treatment, VR group received 20 min VR treatment, and combined treatment group received the same tDCS and VR treatment. Before and 4 weeks after treatment, the Fugl-Meyer assessment-upper limb (FMA-UL), Wolf motor function test (WMFT) and modified barthel index (MBI) were used to evaluate the upper limb motor function and activities of daily life (ADL) of the three groups.Results A total of 45 patients were included, 15 in each group. No adverse reactions or fall off occurred during the treatment. Before treatment, there were no significant difference in FMA-UL, WMFT-Times, WMFT functional ability scores (WMFT-FAS), and MBI between the three groups (P>0.05). After 4 weeks of treatment, the FMA-UL, WMFT-Times, WMFT-FAS, and MBI scores of the three groups were significantly improved compared with those before treatment (P<0.05); the MBI score of the combination treatment group was significantly better than the tDCS group and VR group, and the FMA-UL was significantly better than the tDCS group, and the differences were statistically significant (P<0.05). Also, there were no significant differences in the improvement of FMA-UL, WMFT-Times, WMFT-FAS, and MBI scores between the tDCS group and the VR group (P>0.05); the differences of FMA-UL, WMFT-Times, WMFT-FAS, and MBI scores before and after treatment in the combined treatment group, which were significantly better than those in tDCS group and VR group (P<0.05). Conclusion tDCS combined with virtual reality can significantly improve the upper limb motor function and ADL ability of stroke patients, and the effect is superior to tDCS or VR treatment solely.
