Multimodal imaging of stroke patients. Patients included in the study will be investigated with multiparametric imaging tools including MRI and EEG imaging. Improvements in motor skills will be monitored clinically.
We aim to (i) quantify the size of the brain lesion and assess the surviving functional neural network connections; (ii) Analyze the type and degree of inflammation initiated by the stroke-induced brain lesion. We will stratify inflammation according to lesion volume, surviving functional neural network connections, age, NIHSS and Modified Rankin Scale (mRS) and analyze how inflammation markers change during rehabilitation; (iii) Train the surviving neural network to create new synaptic connections that can maximize restoration of motor functions; (iv) Apply and develop advanced mathematical and computational methods to model and predict how stroke rehabilitation can rewire the neural network connections to best facilitate restoration of lost motor function.

RECRUITINGChanges in brain volume
Stroke induced brain volume changes (mm3) will be measured using magnetic resonance imaging (MRI) at 1 day and 6 months post-stroke.
Time frame: 6 months
Stroke induced changes in brain activity.
Document longitudinal changes in brain activity using EEG. Changes will be measured in cycles/second (Hertz, Hz).
Time frame: 6 months
Changes in inflammatory activity in brain
Markers of post-stroke inflammation will be measured in pg/ml and ng/ml.
Time frame: 6 months
muscle function
Longitudinal kinematic profiling. Electromyography measurements of muscle function post-stroke will be measured in cycles/second (Hz) and amplitude (mm). Extension and flexion of arm will be measured in cm. Joint angles will be measured in degrees. Speed of flexion and extension will be measured in cm/second
Time frame: 6 months
