About this study

Official title: Motor Recovery of Stroke Patients Based on Electroencephalogram-functional Magnetic Resonance Imaging

This study is aimed to investigate the post-stroke motor recovery of patients with ischemic stroke based on their neural features extracted from EEG-fMRI data.

Read the detailed description

A group of patients with ischemic stroke and age/gender matched healthy controls would be enrolled in this study. Their features of neural activities based on EEG-fMRI fusion scan would be extracted to investigate the mechanisms of motor recovery after stroke. Particularly, the correlations of their features of neural networks or local activities to their motor function (defined as their Fugl-Meyer scores) at enrollment and their recovery time courses consisted of Fugl-Meyer scores in follow-up time points. Data of T1 structural, DSI fiber image and pure EEG (without MRI) would also be collected along with EEG-fMRI fusion data.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • MRI recordingDiagnostic test

    MRI imaging was performed using a 3 Tesla Siemens Prisma system with a 64-channel head/neck coil (Siemens Medical Systems, Erlangen, Germany). The MRI protocols included as follows: (i) Magnetization-Prepared 2 Rapid Acquisition Gradient Echoes: TR/TE/ TI1/TI2 = 5000/2.98/700/2500 ms, voxel size = 1.0 × 1.0 × 1.0 mm3, FOV = 256 × 240 × 176 mm3; (ii)Gradient-echo EPI: TR 720 ms, TE 33.1 ms, flip angle 52 deg, FOV 208x180 mm, Matrix 104x90, Slice thickness 2.0 mm; 72 slices; 2.0 mm isotropic voxels, Multiband factor 8, Echo spacing 0.58 ms, BW 2290 Hz/Px; (iii) DSI : TR/TE = 3300/73 ms, FOV = 220 × 220 × 60 mm3, voxel size = 2 × 2 × 2 mm3, 128 diffusion direction, b-max = 3000 sec/mm2, AT = 7:22 min); (iv) T2-weighted fluid-attenuated inversion recovery: TR/TE = 9000/84 ms, FOV = 270 × 320 × 22 mm2, voxel size = 0.72 × 0.72 × 6.6 mm3.

  • EEG recordingDiagnostic test

    EEG was performed using a BrainAmp MR 32 amplifier (BrainProducts GmbH, München, Germany). The EEG protocols included as follows: (i) EEG-fMRI fusion: Sampling rate: 5000 Hz, low cut off-high cut off: DC-1000Hz;(2) EEG-fMRI fusion: Sampling rate: 1000 Hz, low cut off-high cut off: DC-1000Hz.

    In (i) an ECG channel would be used to collect artifact of pulse and not used in (ii).

Study groups in NCT05427422
Study groupRoleWhat they receive
High RecoveryEffective recovery rate defined as difference between Fugl-meyer scores in the 6 weeks after stroke onset (eF) and in the enrollment (sF) normalized by (total score-sf) would be used to indicate the recovery Level of a patients, i.e., (eF-sF)/ (total score-sf). A previously reported recovery rate, i.e., proportional recovery((eF-sF)/(total score-sf)=0.7) was chosen as a standard of a high recovery. Patients with effective recovery rate higher than 0.7 at the T1 time point (6 weeks after stroke onset) would be assigned to group with high recovery rate
Receives: Diagnostic Test: MRI recording; Diagnostic Test: EEG recording
Low RecoveryThe Low Recovery group indicates that patients with effective recovery rate lower than 0.7
Receives: Diagnostic Test: MRI recording; Diagnostic Test: EEG recording
Healthy ControlAge/sex matched healthy subjects enrolled to compare with group of patients.

Questions about this trial

What is this clinical trial studying?

An observational study of Motor Neuropathy, run by Xi'an Jiaotong University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

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. 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?

Fugl-Meyer scores (T0) (time frame: 7-14 days since stroke). The study lists 4 primary outcomes in all. 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 19 Sep 2024.
