Evaluation of Clinical Efficacy and Mechanism of Hand Jing-Well Acupoint Transcutaneous Electrical Stimulation in Improving Post-Stroke Cognitive Impairment
This study evaluates a non-invasive electrical stimulation therapy applied to specific acupoints on the fingers (called Jing-Well points) to improve thinking and memory problems after stroke. Purpose: Many stroke survivors develop cognitive difficulties (problems with memory, attention, and decision-making). Current treatments are limited. This study tests whether gentle electrical stimulation to hand acupoints can improve these symptoms. Who can participate: Adults aged \[35-80\] who have had an ischemic stroke and now have mild to moderate cognitive impairment. What happens: Participants will be randomly assigned to receive either (1) active electrical stimulation to hand Jing-Well points, (2) sham (fake) stimulation. Treatment will last 4 weeks, 6 sessions per week, each 30 minutes, with a stimulation frequency of 10 Hz and intensity adjusted to each participant's tolerance. Cognitive tests and brain imaging will be done before and after treatment. Potential benefits: Participants may experience improved cognitive function. The study will also help researchers understand how this therapy works in the brain. Risks: The electrical stimulation may cause mild tingling or skin irritation at the electrode sites. Brain imaging is non-invasive and safe. All procedures will be performed by trained professionals.
• Aged 35-80 years;
• Stroke duration within 2 weeks to 6 months post-onset;
• Cognitive impairment confirmed by neuropsychological assessment: Montreal Cognitive Assessment (MoCA) score \< 26;
• Clinical evaluation excludes delirium, major depressive disorder, schizophrenia, or other primary psychiatric/behavioral disorders as the principal cause of current cognitive impairment. No history of other known neurological diseases that may cause cognitive impairment (e.g., multiple sclerosis, encephalitis, Parkinson's disease, post-traumatic dementia, normal pressure hydrocephalus, etc.);
• No severe aphasia; able to cooperate with scale assessments and complete the treatment protocol required by this study;
• Voluntary participation in this study; the participant or their legally authorized representative has signed the informed consent form.
