Introduction

Neurological diseases encompass a wide spectrum of disorders affecting the central and peripheral nervous systems, often leading to debilitating impairments in various aspects of motor function and coordination. Among the numerous challenges faced by individuals living with neurological diseases, deficits in balance and postural stability stand out as particularly pervasive and impactful. The loss of balance not only hampers daily activities but also increases the risk of falls, injuries, and a decline in overall quality of life. In recent years, there has been a growing interest in exploring innovative interventions to ameliorate balance impairments in neurological diseases [1 ]. One such intervention that has gained prominence is Transcranial Direct Current Stimulation (tDCS). tDCS is a non-invasive neuromodulation technique that involves the application of a weak electrical current to specific regions of the brain via surface electrodes. By modulating cortical excitability and synaptic plasticity, tDCS has shown promise in enhancing motor function and potentially aiding in balance rehabilitation. Despite the increasing adoption of tDCS in clinical and research settings, there remains a need for a comprehensive evaluation of its efficacy and safety in addressing balance deficits across different neurological diseases [2 ]. The heterogeneity of neurological conditions, variations in tDCS protocols and a growing body of literature on the subject necessitate a systematic study and meta-analysis to synthesize existing evidence and provide a clearer understanding of the role of tDCS in balance rehabilitation. This systematic study and meta-analysis aim to fill this critical knowledge gap by aggregating data from a range of studies across various neurological diseases. We will assess the overall effect of tDCS on balance outcomes, explore potential sources of heterogeneity, and provide insights into the clinical relevance of tDCS as an adjunctive therapy for improving balance and postural stability [3]. Ultimately, this research contributes to advancing our understanding of the potential benefits of tDCS in neurological rehabilitation, potentially paving the way for more effective and personalized interventions to enhance the lives of individuals living with neurological diseases [4].

Discussion

Efficacy of tDCS in Balance Rehabilitation: The meta-analysis conducted in this systematic study provides compelling evidence for the efficacy of Transcranial Direct Current Stimulation (tDCS) as an adjunctive therapy for balance rehabilitation in neurological diseases. The statistically significant overall effect size suggests that tDCS can lead to meaningful improvements in balance outcomes. This finding aligns with the growing body of literature indicating that tDCS has the potential to enhance motor function and postural control. It is noteworthy that the effectiveness of tDCS in balance rehabilitation varies across different neurological diseases. Subgroup analyses revealed that individuals with Parkinson’s disease and stroke experienced particularly significant improvements in balance with tDCS [5]. This variability may be attributed to the unique pathophysiological mechanisms underlying each condition and underscores the importance of tailoring interventions to specific patient populations. Clinical Implications: The positive outcomes observed in this meta-analysis have important clinical implications. Balance impairment is a common and debilitating symptom in many neurological diseases, and effective interventions are urgently needed to improve the quality of life for affected individuals. The use of tDCS as an adjunctive therapy offers a promising avenue for clinicians to address balance deficits, potentially reducing the risk of falls and related injuries [ 6 ]. An important consideration in any intervention is its safety profile. In this meta-analysis, tDCS appeared to be well-tolerated, with minimal reported adverse effects. This finding is consistent with the non-invasive nature of tDCS and its relatively low risk compared to more invasive neuromodulation techniques. Nevertheless, continued monitoring of safety and long-term effects is essential as tDCS continues to be integrated into clinical practice. It is essential to note that the efficacy of tDCS may depend on various factors, including stimulation parameters such as electrode placement, current intensity, and duration of sessions. Future research should focus on optimizing these parameters to maximize the benefits of tDCS in balance rehabilitation [7 ]. Additionally, individualized approaches tailored to each patient’s specific neurological condition and needs may yield even more significant improvements. This meta-analysis is not without limitations, including potential publication bias and heterogeneity among the included studies. Future research should strive to address these limitations and expand our understanding of tDCS in balance rehabilitation. Long-term follow-up studies are needed to assess the durability of tDCS-induced improvements and its potential for neuroplasticity [8].

Conclusion

In conclusion, the findings of this systematic study and metaanalysis support the use of tDCS as a valuable adjunctive therapy for balance rehabilitation in neurological diseases. The observed benefits, particularly in Parkinson’s disease and stroke, underscore the potential of tDCS to positively impact the lives of individuals with balance deficits. Further research and clinical trials are warranted to refine protocols, enhance our understanding of mechanisms, and establish tDCS as a standard of care in neurological rehabilitation. Future research should address these limitations and investigate the long-term effects and mechanisms underlying tDCS-induced improvements in balance. Additionally, comparative studies with other neuromodulation techniques and traditional rehabilitation approaches could provide further insights. In summary, the evidence presented in this systematic study and meta-analysis supports the incorporation of tDCS into the clinical toolbox for balance rehabilitation in neurological diseases. The observed benefits, particularly in Parkinson’s disease and stroke, offer hope for improved functional outcomes and a higher quality of life for those affected. As research in this field continues to evolve, tDCS holds the potential to become an integral component of neurological rehabilitation strategies, enhancing the well-being of individuals facing the challenges of balance deficits in the context of neurological diseases.
