Abstract
OBJECTIVE: Acupuncture treatment helps to improve neurological and motor function in elderly patients with stroke hemiplegia. However, the exact mechanism by which electroacupuncture improves stroke hemiparesis is uncertain. The aim of this study was to determine the effect of electroacupuncture care on sirt3 levels in elderly patients with stroke hemiparesis. METHODS: One hundred and ten elderly patients with hemiplegia after first stroke were divided into an experimental group and a control group (n = 55 in each group). The control group was given conventional rehabilitation care by a rehabilitation therapist. In the experimental group, on the basis of conventional rehabilitation care, electroacupuncture was performed once a day for 28 days. RESULTS: Fugl-Meyer assessment (FMA) and barthel index (BI) scores were significantly higher, while neurologic deficit scale (NDS) and physiological state scores were significantly lower in both groups after 14 and 28 days of intervention compared to preintervention. The Generalized estimating equation (GEE) model also showed that the experimental group showed more favorable improvements in all outcomes at postintervention time points compared to the control group. After the intervention, serum sirt3 levels increased significantly in both groups compared to preintervention, and the increase was more pronounced in the experimental group. Consistently, the GEE model showed that serum sirt3 levels were significantly higher in the experimental group compared to the control group at postintervention time points. Correlation analysis revealed that serum sirt3 levels in the experimental group were negatively correlated with FMA and BI pre- and postintervention, while showing a significant positive correlation with NDS and physiological state scores. CONCLUSION: Electroacupuncture intervention led to significant improvements in motor function, activities of daily living and neurological function in elderly patients with stroke hemiplegia, which may be associate with increased serum sirt3 levels.
