Unveiling the Potential of Transcranial Direct Current Stimulation in Enhancing Trunk Motor Control and Balance in Cerebrovascular Accident Survivors: A Scoping Review.
Unlocking the potential of transcranial direct current stimulation (tDCS) to bolster trunk motor control and balance in cerebrovascular accident (CVA) survivors has been a focal point in recent literature. It is a non-invasive brain stimulation found to be useful in promoting corticomotor excitability aiming for neuroplasticity in CVA survivors. This review delved into the recently available work published, scouring five prominent databases for English-language studies from 2014 to 2023. Eight articles were reviewed. While tDCS has shown promise in spurring corticomotor excitability and fostering neuroplasticity in CVA survivors, its application specifically targeting trunk control and balance remains scant. Nevertheless, the evidence suggests a noteworthy enhancement in post-CVA balance control, particularly with interventions combining tDCS with other interventions including functional electrical stimulation and balance training. This review illuminates the potential of tDCS, either standalone or integrated with conventional physiotherapy, in fortifying trunk control among CVA survivors.
