Talk with your doctor about your goals for treatment. If your doctor thinks you are a good candidate for spinal cord stimulation, you can complete a screening test to see whether spinal cord stimulation will provide adequate pain relief.Back to top
Your participation in the trial allows you and your doctor to evaluate whether you are a good candidate for spinal cord stimulation. The purpose of the trial is to determine your response to neurostimulation, if it reduces your chronic pain, if it helps you meet your goals, and whether a neurostimulation system is the right pain treatment for you.
The screening test period lasts approximately 3 to 7 days.
You will have local anaesthesia when the leads are placed. There may be some occasional discomfort during the procedure and you may have pain at the incision site once the anaesthesia wears off. You should not have pain or discomfort during the rest of the trial period.
Your clinician may reduce or withdraw your oral medication 1 to 2 weeks prior to the trial. During the trial, oral medication may be given for breakthrough pain. Never stop taking your prescribed pain medication without first consulting your clinician.
If the trial has been successful and you go on to receive the permanent system, your pain relief may differ slightly. This is because the leads may be in a slightly different location than during the trial. Be sure to tell your clinician about the way you feel so that changes can be made that will give you the best pain relief possible.
If you decide to proceed with spinal cord stimulation, in most cases there will be a waiting period after the trial and before your implant procedure. This will give the area in your back where the leads were placed time to heal, and for the surgery to be scheduled.
As you change positions, your pain may change. As a result of these changes in pain, your neurostimulation system may have to be adjusted to provide continued comfort.
Depending on the neurostimulator you and your doctor choose, you can either adjust the stimulation manually by using your programmer, or your neurostimulator will automatically adjust it when you change positions, using a technology called AdaptiveStim®. AdaptiveStim is available only from Medtronic, with the RestoreSensor® neurostimulator.
Typically, the implant of the neurostimulator is performed under general anaesthesia. However, you may wish to talk with your doctor about other options.
Depending on your doctor's preference and hospital policy, a hospital stay may be recommended.
There are two incisions, both 2 to 4 inches long.Back to top
In rare cases, you may experience a "spinal headache." A spinal headache is caused when cerebrospinal fluid (the fluid that surrounds your spinal cord) leaks out from the intrathecal or epidural space. This headache may correct itself, or your doctor may treat it.Back to top
In rare cases, spinal cord injury may occur from surgical placement of the lead.Back to top
No, because the incision needs to be made where the neurostimulator will be implanted to help properly anchor the device.Back to top
This depends on your specific condition and the results you received from the trial. Your doctor will advise you of the recommended location.
The neurostimulator does not make any noise. The device does not normally show through your clothes. It is usually implanted in the lower abdomen or upper buttock, where it is most comfortable and least visible. It may be felt as a small bulge under your skin.Back to top
Yes. The trial is designed to minimise the possibility that neurostimulation will not help manage your pain. If you no longer need the neurostimulator or change your mind about the treatment, your doctor can turn off the system at any time.
When you have an implanted electronic device, you have to be careful about MRI scans. The good news is that MRI scans are possible with Medtronic neurostimulation systems for chronic pain,* with proper safeguards. In fact, only Medtronic offers neurostimulation systems that allow safe** access to MRI scans anywhere in the body, under specific conditions.
* Excludes Itrel® 3
** Under specific conditions and requires SureScan® MRI implantable neurostimulator and SureScan MRI leads
