Effects of Anodal Transcranial Direct Current Stimulation on Postural Stability in Sub-Acute Stroke
Effects of Anodal Transcranial Direct Current Stimulation on Postural Stability in Sub-Acute Stroke
Stroke patients experience weakening of muscles on the affected side. Damage to the motor cortex and the pyramidal tract due to a stroke leads to a motor control disorders and co-contraction of trunk muscles due to abnormal levels of abdominal muscle tension and voluntary movement.
TDCS is known to modulate motor excitability in humans and motor performance is crucial in postural control. Studies reports that applying anodal TDCS to the ipsilesional motor cortex improved motor functioning in which the Transcranial Direct Current Stimulation may have stimulated preserved areas of the motor cortex to enhance synaptic efficiency along the corticospinal tract.
Anodal TDCS has been shown to have immediate and short-term effects in stroke but its long-term effects in stroke are still unclear. Additionally, the available literature focuses on acute and chronic stages of stroke so we will target subacute stage of stroke. Therefore, this study is designed to investigate the short and long-term effects of Anodal Transcranial Direct Current Stimulation on postural stability in subacute stroke.
