简要总结
In patients with ischemic stroke, the primary focus revolves around enhancing the neuroprotective and rehabilitative effects of external trigeminal nerve stimulation (eTNS) and elucidating its underlying central mechanisms. Through clinical trials and neuroimaging studies, this research endeavors to 1) investigate the clinical impact of TNS on brain protection and 2) rehabilitation acceleration in ischemic stroke patients, while concurrently exploring the potential central nervous mechanisms involved. The ultimate aim is to contribute a novel therapeutic approach to the clinical management of acute ischemic stroke.
详细描述
This study conducted a randomized controlled clinical trial with an intention to enroll 60 patients. Patients were randomly assigned in a 1:1 ratio to two groups: 1) External trigeminal nerve stimulation (eTNS) group (intervention group); 2) Standard treatment group (control group). eTNS was administered once daily for 30 consecutive days during the treatment period. The eTNS stimulation protocol entailed targeting the bilateral supraorbital region as the non-invasive stimulation site, with treatment administered for 30 days (once daily, during nighttime sleep for a minimum of 8 hours per day; stimulation parameters set at 120 Hz, 250 μs, 30s ON-30s OFF, with intensity adjusted to individual comfort levels). For the standard treatment group, a series of interventions excluding eTNS, as directed by the treating physician, were administered (including but not limited to medications and rehabilitation therapies). Blood samples and medical history information were collected at baseline. Imaging data were acquired from participants at baseline and 5 days post-treatment. Modified Rankin Scale (mRS), National Institutes of Health Stroke Scale (NIHSS), and Barthel Index (BI) were assessed at baseline, 5 days post-treatment, at the end of treatment, and at 1- and 2-month follow-ups. Additionally, the 9-item Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder 7-item scale (GAD-7), and Insomnia Severity Index (ISI) were administered at baseline, the end of treatment, and at 1- and 2-month follow-ups to evaluate participants' emotional well-being and sleep patterns. The recruited sample size met statistical requirements.

结局指标
主要结局
Response rate after five days of treatment
时间窗: NIHSS will be assessed five times within 90 days: at baseline (prior to participant enrollment), and on days 5, 30, 60, and 90 post-enrollment.
The National Institutes of Health Stroke Scale (NIHSS) is employed to evaluate the extent of functional impairment caused by stroke. Comprising 11 test items, the scale's scoring ranges from 0 to 42. Higher scores are indicative of more severe strokes and are positively correlated with the volume of cerebral damage caused by the stroke. Response is defined as a decrease in NIHSS (National Institutes of Health Stroke Scale) score by 4 points or more, or a decrease to 0-1 points after treatment. The response rate is the proportion of participants whose NIHSS scores decrease by 4 points or more, or to 0-1 points, compared to baseline.
次要结局
- Infarct volume growth rate(Imaging data will be collected twice within 90 days: at baseline (prior to participant enrollment) and on the fifth day of treatment.)

- Change in ISI scores(ISI will be assessed four times within 90 days: at baseline (prior to participant enrollment), and on days 30, 60, and 90 post-enrollment.)
- Correlation Between Time to Treatment and Intervention Outcomes(The time from stroke onset to treatment will be recorded prior to enrollment.)
- Change in NIHSS scores(NIHSS will be assessed five times within 90 days: at baseline (prior to participant enrollment), and on days 5, 30, 60, and 90 post-enrollment.)
- Change in BI scores(BI will be assessed five times within 90 days: at baseline (prior to participant enrollment), and on days 5, 30, 60, and 90 post-enrollment.)
- Change in mRS scores(mRS will be assessed five times within 90 days: at baseline (prior to participant enrollment), and on days 5, 30, 60, and 90 post-enrollment.)
- Correlation Between Medical History and Intervention Outcomes(Medical History will be collected at baseline (prior to participant enrollment))
- Change in PHQ-9 scores(PHQ-9 will be assessed four times within 90 days: at baseline (prior to participant enrollment), and on days 30, 60, and 90 post-enrollment.)
- Correlation Between Blood Inflammatory Markers and Stroke Severity and Intervention Outcomes(Blood samples will be collected at baseline (prior to participant enrollment))
