Brief Summary:
The objective of this study is to better understand the structural and functional changes that the central nervous system (CNS) undergoes following spinal cord injury and how these changes relate to clinical measures. Both macroscopic and microscopic changes of the brain and the spinal cord will be examined in SCI patients and compared to healthy controls. In terms of structural plasticity, we aim to identify MR biomarkers that allow predicting the course of the patient's neurological status and accurately describe the course of the disease and the recovery. Importantly, we aim to investigate which factors scale the patients' symptoms. In terms of functional plasticity, we will combine fMRI with behavioural testing to understand which clinical and behavioural determinants drive functional hand representations in the primary somatosensory and motor cortices to be maintained and which determinants drive reorganisation of functional representations following sensory input loss. We will further investigate the contribution of brainstem reorganisation to plasticity observed at the cortical level and, by doing so, aim to better understand the mechanistic underpinnings of functional reorganisation.

Group/Cohort Intervention/treatment
Patients with spinal cord injury Diagnostic Test: MRI
We will examine chronic (>6 months post SCI) patients using functional, structural, and metabolic MRI in both the brain and the spinal cord.

Healthy subjects Diagnostic Test: MRI
We will examine healthy control participants using functional, structural, and metabolic MRI in both the brain and the spinal cord.




Primary Outcome Measures :
  1. Conventional magnetic resonance imaging (MRI) parameter [ Time Frame: Up to 50 weeks ]
    Structural characteristics in the brain and cervical spinal cord are assessed in chronic spinal cord injury (SCI) patients using conventional MRI and compared to healthy controls


Secondary Outcome Measures :
  1. Magnetic resonance spectroscopy (MRS) parameter [ Time Frame: Up to 50 weeks ]
    Metabolic parameters are assessed in chronic SCI patients using MRS in the brain and cervical spinal cord and compared to healthy controls

  2. Change of functional MRI (fMRI) parameter between 2 to 4 time points [ Time Frame: Up to 50 weeks ]
    Change of brain activities is assessed between 2 to 4 time points using fMRI during resting-state or a specific task in chronic SCI patients and compared to healthy controls
