About this study
The purpose of this study was to investigate the effect of repetitive transcranial magnetic stimulation on cerebral autoregulation in patients with acute ischemic stroke.
Read the detailed description
Current studies have shown that repetitive transcranial magnetic stimulation can change the excitability of nerve cells, improve intracerebral artery blood supply, and even reduce the degree of neurological impairment in patients with ischemic stroke. The purpose of this study was to investigate the effect of repetitive transcranial magnetic stimulation on cerebral autoregulation in patients with acute ischemic stroke.
- Conditions
- Transcranial Magnetic Stimulation
- Being tested
- Repetitive transcranial magnetic stimulation, Sham repetitive transcranial magnetic stimulation
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Repetitive transcranial magnetic stimulationProcedure or surgery
After enrollment, patients received rTMS once a day for 5 consecutive days (stimulation plan: stimulation of M1 region on the affected side at 10Hz).
Sham repetitive transcranial magnetic stimulationProcedure or surgery
After enrollment, patients received sham-rTMS once a day for 5 consecutive days with the same parameters as the rTMS group, but the coil was rotated 90° away from the scalp.
| Study group | Role | What they receive |
|---|---|---|
| rTMS | Active comparator | Patients are treated with repetitive transcranial magnetic stimulation (rTMS). Receives: Procedure: Repetitive transcranial magnetic stimulation |
| sham-rTMS | Placebo comparator | Patients are treated with sham repetitive transcranial magnetic stimulation (sham-rTMS). Receives: Procedure: Sham repetitive transcranial magnetic stimulation |
What is being measured
The primary outcome is the main question the study is designed to answer.
phase difference(PD) in degree
A cerebral autoregulation parameter derived from transfer function analysis. Continuous cerebral blood flow velocities of bilateral middle cerebral artery will be assessed noninvasively using transcranial Doppler. Spontaneous arterial blood pressure will be simultaneously recorded using a servo-controlled plethysmograph on the left or right middle finger with an appropriate finger cuff size. Transfer function analysis will be used to derive the cerebral autoregulatory parameter.
Measured: 0-5 days

Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
phase difference(PD) in degree (time frame: 0-5 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Apr 2025.
