About this trial

Building on recent improvements, state-of-the-art functional MRI will be applied as an advanced diagnostic tool for the lumbosacral cord in spinal cord injury (SCI) patients to characterize the remaining neuronal activity of the motor and sensory neurons. Alterations in the activity pattern will reveal the effect upon task-related spinal cord activity of the lower motor neurons and sensory neurons undergoing trauma-induced neurodegeneration, at a spatial specificity that has not been possible so far. Results of this study will be of crucial importance because SCI patients can only profit from regeneration-inducing therapies if spinal neuronal function is preserved below the level of lesion.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Age > 18 years

Informed consent

Willing to take part and follow requirements of the protocol

Chronic traumatic SCI (> 12 months after injury) or

Disqualifiers

Age < 18 years

Contraindications for MRI (presence of pacemaker or other type of stimulator in the body, presence of metallic foreign body in or on the body, etc.); we will comply with the imaging center's (SCMI) guidelines and in case of doubt we will exclude the participant from the study

No informed consent

History of psychiatric or neurological disease, apart from those induced by SCI (e.g.epilepsy)

Trial population

The participants will be recruited from the primary care clinic as well as via flyers distributed at hospital waiting rooms and patient support organisations. Healthy controls will be recruited via public announcements and via flyers distributed at the primary care clinic and two universities.

Time frame
Baseline only
2

Longitudinal study: lumbosacral functional fMRI

Activations in the gray matter of the lumbosacral cord, as a response to sensory, motor, and somatosensory stimulations, or no stimulation (resting state). Spatiotemporal components of the BOLD signal as well as the couplings and anti-couplings between these component

Time frame
Change from baseline at 2-month, 6-month, and 12-month
