Abstract: Stroke is a common neurological disease. Post-stroke sensory disorder is one of the common complications of stroke, which has severe negative impact on motor function and activity participation of patients. Transcranial direct current stimulation （tDCS）, a technique that uses 1 to 2 mA of direct current to modulate the cerebral cortex, is non-invasive, safe and well tolerated by patients. This study elaborates on the theoretical basis and mechanism of action of tDCS in treating post-stroke sensory disturbances, and analyzes and summarizes the application of tDCS in post-stroke sensory disturbances, confirming the effectiveness of tDCS, providing strong support for further clinical research of tDCS in the field of post-stroke rehabilitation.
