Various studies have investigated the effect of noninvasive brain stimulation methods such as transcranial direct stimulation (tDCS) on postural control in healthy young and older adults. However, the use of different treatment protocols and outcome measures makes it difficult to interpret the research results. This systematic review provides a comprehensive overview of the current literature on the effect of tDCS on postural control. Nine databases were searched for papers assessing the effect of tDCS on postural control in young healthy and/or older adults. The data of included studies were extracted and methodological quality examined using PEDro. Sixteen studies met the inclusion criteria. The results showed that anodal tDCS (a-tDCS) of primary motor cortex may improve dynamic balance in young healthy individuals. In older adults, a-tDCS of dorsolateral prefrontal cortex and cerebellum showed a positive effect on dual task and dynamic balance, respectively. In conclusion, tDCS may improve both static and dynamic balance in younger and older adults. However, due to lack of consensus in the results, caution is required when drawing conclusions with regards to these findings.
许多研究调查了非侵入性脑刺激方法（如经颅直流电刺激（tDCS））对健康年轻和老年成年人姿势控制的影响。然而，由于使用了不同的治疗方案和结果测量方法，使得研究结果难以解释。本系统综述提供了关于 tDCS 对姿势控制影响的当前文献的全面概述。在 9 个数据库中搜索了评估 tDCS 对年轻健康成年人和/或老年人姿势控制影响的论文。使用 PEDro 提取纳入研究的数据并检查方法学质量。16 项研究符合纳入标准。结果表明，初级运动皮层的阳极 tDCS（a-tDCS）可能改善年轻健康个体的动态平衡。在老年人中，背外侧前额叶皮层和小脑的 a-tDCS 分别对双重任务和动态平衡产生积极影响。总之，tDCS 可能改善年轻和老年成年人的静态和动态平衡。然而，由于结果缺乏共识，在得出这些发现的结论时需要谨慎。
