Effect of Specific Mode Electroacupuncture Stimulation Combined with NGF on Dysphagia After Ischaemic Stroke: a Pilot Randomized Controlled Trial

Inclusion Criteria: 1. Patients with first-ever ischemic stroke confirmed by Computed Tomography (CT) and/or Magnetic Resonance Imaging (MRI); 2. Onset time ranged from 15 days to 180 days; 3. Aged 18 to 80 years old, male or female; 4. Dysphagia confirmed by a videofluoroscopic swallowing study (VFSS); 5. Patients who are able to accept and comply with acupuncture, electroacupuncture treatment, gluteal intramuscular injection, and have good compliance; 6. Have provided signed consent and exhibit willingness to participate in the trial. 7. Women who are lactating, pregnant or intending to get pregnant; Exclusion Criteria: 1. Patients with dysphagia before ischemic stroke onset or dysphagia not caused by ischemic stroke; 2. Patients with severe cognitive impairment; 3. Patients with severe cardiac, hepatic, and renal dysfunction, as well as severe coagulation abnormalities; 4. Patients with other abnormal test results who are deemed unsuitable to participate in this study by the investigator. 5. Multiple occurrences of stroke, or a history of craniocerebral surgery, or cerebral infarction caused by trauma or brain tumors. 6. Patients with severe neurological deficits prior to ischemic stroke, such as visual and auditory impairments, aphasia, agnosia, severe hemiplegia, and other conditions. 7. Women who are lactating, pregnant or intending to get pregnant; 8. Patients with a history of needle fainting or with skin infections at the acupuncture site. 9. Cardiac pacemaker carrier; 10. Patients allergic to NGF; 11. The inability to undergo VFSS; 12. Patients with a medication history that may alter cortical excitability within the past 2 months. 13. Patients who are currently participating in other clinical trials or have participated in clinical trials that ended within the last 3 months.
