Effects of Repetitive Transcranial Magnetic Stimulation on Cerebral Autoregulation in Patients With Acute Ischemic Stroke

February 27, 2024 updated by: Yi Yang
The purpose of this study was to investigate the effect of repetitive transcranial magnetic stimulation on cerebral autoregulation in patients with acute ischemic stroke.

Study Overview

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.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Double

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: rTMS
Patients are treated with repetitive transcranial magnetic stimulation (rTMS).
After enrollment, patients received rTMS once a day for 5 consecutive days (stimulation plan: stimulation of M1 region on the affected side at 10Hz).
Placebo Comparator: sham-rTMS
Patients are treated with sham repetitive transcranial magnetic stimulation (sham-rTMS).
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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
phase difference(PD) in degree
Time Frame: 0-5 days
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.
0-5 days
