Reorganization of Brain Functions in Patients With Cervical Myelopathy Using fMRI and MRS
Canada35 participantsStarted 2008-09
Plain-language summary
Decompressive surgery to relieve symptoms of spinal cord compression due to dysfunction, such as arthritis, has proved variable in success. Past research has reported that approximately one-third of surgery patients improved, one-third remained the same and one-third worsened. Currently, there are no reliable tests that can predict the outcome following surgery. We are hoping that this study will change that.
Using functional MRI (fMRI), we wish to investigate the relationship between clinical symptoms and the recovery of brain activation following surgery. One can also track the concentrations of different chemicals (metabolites) by using magnetic resonance spectroscopy (MRS). We hypothesize that the recovery of normal brain activation patterns will coincide with clinical improvement. Our objective in this study is to explore the potential role of fMRI as a tool to prognose patients with cervical myelopathy.
Twenty-five patients with cervical myelopathy will be imaged using a high-powered (3 Tesla) fMRI scanner before and six months following surgery. In addition, ten healthy controls will be imaged to provide a baseline measure. Both the patient and control groups will complete questionnaires at the time of their scans. These will provide information concerning the subjective experience of the individuals throughout recovery. We will compare brain activation patterns of control and patient groups to investigate how the brain heals following decompressive surgery.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
