Intervention / Treatment
Detailed Description
Serial measurements (immediately after being transferred to rehabilitation department [T0], at discharge from inpatient rehabilitation [T1], and follow up at one to three months from stroke onset [T3]) using Functional Near-Infrared Spectroscopy (fNIRS) was done in all participants. The primary outcome was the outcome prediction rate using fNIRS parameter and clinical parameters. Secondary outcomes were as follows: fNIRS activation pattern, Laterality Index, Functional Connectivity, Fugl-Meyer Score, Modified Barthel Index, , Brunnstrom Stage, Box and Block Test, Grip Strength (handgrip, pinch grip, lateral prehension, three-jaw chuck), Modified Ashworth Scale (wrist flexor and extensor spasticity, elbow flexor, and extensor spasticity, long finger flexor spasticity), modified Rankin Scale score, Functional Ambulation Category, Glasgow Coma Scale, Neglect Evaluation Battery, Korean Version Western Aphasia Battery, and Scale for the Assessment and Rating of Ataxia.
The changes in the fNIRS measurements and clinical parameters will be analyzed and also the correlation between the two will be analyzed to identify the prognostic value of fNIRS.

fNIRS applied
All of the participants' brain activity was evaluated with fNIRS.
|
Functional near-infrared spectroscopy (fNIRS) is a non-invasive method that can evaluate the brain function by measuring the change in brain metabolic activity and hemodynamics during a given task with near-infrared spectroscopy.
