Summary

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.

Conditions

  • Motor Neuropathy

Interventions

DIAGNOSTIC_TEST

MRI recording

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.

DIAGNOSTIC_TEST

EEG recording

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).
