Transcranial direct current stimulation (tDCS) for improving function and activities of daily living in patients after stroke.

Stroke is one of the leading causes of disability worldwide. Functional impairment resulting in poor performance in activities of daily living (ADLs) among stroke survivors is common. Current rehabilitation approaches have limited effectiveness in improving ADL performance and function after stroke, but a possible adjunct to stroke rehabilitation might be non-invasive brain stimulation by transcranial direct current stimulation (tDCS) to modulate cortical excitability and hence to improve ADL performance and function.
