Purpose : Transcranial direct current stimulation is noninvasive method of cerebral cortical stimulation applied as an intervention to facilitate recovery in stroke patients. The purpose of this study was to examine the effects of transcranial direct current stimulation on depression and anxiety in stroke patients with the aim to finding a reliable method to reduce depression and anxiety in stroke patients.
Methods : This study was conducted at A hospital located in D city from December 2022 to February 2023. Patients diagnosed with stroke were selected according to predefined study criteria and divided into two groups. 9 patients in experimental group underwent transcranial direct current stimulation and traditional occupational therapy, while 9 patients in the control group underwent sham transcranial direct current stimulation and traditional occupational therapy for 20 min per session 3 times per week for a total of 8 weeks. Beck depression inventory (BDI) and Beck anxiety inventory (BAI) were used to evaluate depression and anxiety in the patients before and after intervention. Wilcoxon signed rank test was used to compare differences before to after intervention. Mann-Whitney U test was used to compare the two groups. Differences with p<.05 were considered statistically significant.
Results : First, both the experimental and control groups presented significant statistical difference before and after intervention on depression (p<.01). Comparison of two groups after intervention showed significant statistical difference in depression (p<.05). Second, the groups presented significant statistical difference before and after intervention on anxiety (p<.01). After intervention, the two groups showed significant statistical difference in anxiety (p<.05).
Conclusion : Results of the present study demonstrated the effects of transcranial direct current stimulation on depression and anxiety in stroke patients, suggesting it may be a useful method of rehabilitation in this patient population; as such, further studies are warranted.
