Background and study aims
Stroke is the second leading cause of disability and death across the world. The annual number of strokes and deaths caused by stroke increased constantly, and the stroke burden has been increasing in recent years. Ischemic stroke composed 62.4% of total incident strokes in 2019. Mechanical thrombectomy (removing a blood clot through a catheter) and intravenous thrombolysis (injection of clot-busting drugs) are recommended for acute ischemic stroke but strict period windows and indications limit their clinical use. The aim of this study is to evaluate the effectiveness and reveal the mechanism of electroacupuncture (EA) for ischemic stroke.

Who can participate?
Patients aged 18-80 years with acute and subacute ischemic stroke

What does the study involve?
Patients will be randomly allocated to two groups. The patients in the EA group will receive EA treatment, while the sham EA group will receive sham EA. Participants will be evaluated at the start of the study, 24 hours after the first treatment, and at weeks 1, 2 and 3 and blood samples will be collected.

What are the possible benefits and risks of participating?
Both groups will receive basic treatment and symptomatic treatment. Participants' symptoms may be relieved in this study. Acupuncture may cause some slight side effects, including bleeding, hematoma, serious pain, and dizziness. These side effects are generally mild and rarely cause serious harm.

Where is the study run from?
Luohu District Hospital of Traditional Chinese Medicine (China)

When is the study starting and how long is it expected to run for?
November 2022 to October 2025

Who is funding the study?
Science, Technology and Innovation Commission of Shenzhen Municipality (China)

Scientific titleEfficacy and mechanism of electroacupuncture in the treatment of ischemic stroke: a prospective randomized controlled trial
Study objectivesElectroacupuncture (EA) has better efficacy than sham EA in improving neurological function. EA improved neurological function by regulating serum RNA and metabolites.
Ethics approval(s)Approved 07/02/2023, Ethics Committee, Luohu District Hospital of Traditional Chinese Medicine (16 Xiantong Rd. Luohu District, Shenzhen, 518004, China; +86 (0)755 82311699; lhzyykjk@163.com), ref: 2023-LHQZYYYXLL-KY-001
Health condition(s) or problem(s) studiedAcute and subacute ischemic stroke patients
InterventionEligible patients will be randomly allocated into the EA group or sham EA group. SPSS 26.0 will be used to generate the randomization sequence and allocation ratio. Group allocation data will be concealed in predetermined, sequentially numbered, opaque, and sealed envelopes, produced by a third-party professional statistician.

The EA group will receive EA while the sham EA group will receive sham EA. Acupoints in both groups are as follows: Baihui (GV20), affected side Zusanli (ST36), affected side Futu (ST32), affected side Shousanli (LI10), affected side Shouwuli (LI13). The participants will receive EA or sham EA treatment 30 times in 3 weeks, five times a week.

Disposable single-use sterile needles will be inserted into acupoints at a depth of 5–15 mm after the skin is disinfected with alcohol. The HANS EA apparatus will be connected to needles. Electric stimulation will be operated with a dense-disperse wave, 20 Hz/100 Hz in frequency. The current intensity will be 5-10 mA in the acute phase while 1-3 mA in the subacute phase. Each treatment will last for 30 min. The sham EA group will receive sham EA, which uses a blunt needle without skin current.
Intervention typeOther
Primary outcome measureNeurological dysfunction assessed using the National Institute of Health stroke scale (NIHSS) at baseline, 24 hours after the first treatment, and weeks 1, 2 and 3
Secondary outcome measures1. Neurological function measured using the Fugl-Meyer Assessment (FMA) at baseline and weeks 1, 2 and 3
2. Activity of daily living measured using the Modified Barthel index (MBI) at baseline and weeks 1, 2 and 3
3. Cognitive function measured using the Mini-Mental State Examination (MMSE) at baseline and weeks 1, 2 and 3
4. Transcriptomic sequencing using blood samples collected before the first treatment, 24 hours after the first treatment, and weeks 1, 2 and 3
5. Metabolomic sequencing using blood samples collected before the first treatment, 24 hours after the first treatment, and weeks 1, 2 and 3
