Neuromodulation And Spinal Cord Stimulation
Neurostimulation is the use of electrical impulses to block or restore nervous system function and sensation.
Neurostimulation treatment reduces nerve activity through the delivery of electrical stimulation to targeted sites of the body.
The various form of neuromostimulation used for pain control include:
Spinal cord stimulation (SCS)
Peripheral nerve stimulation (PNS or PENS)
Occipital nerve stimulation (ONS)
Sacral nerve stimulation (SNS)
Spinal cord stimulation therapy works by delivering a mild electrical impulse to the spinal cord to block pain signals from traveling up to the brain. It is a treatment generally reserved for severe intractable neuropathic pain.
The various forms of SCS include:
Dorsal root ganglion (DRG) stimulation
High frequency stimulation
High density stimulation
Patients are considered for neurostimulation if they have moderate to high intensity persistent neuropathic pain and if more conservative strategies have been comprehensively applied and have failed. This is called refractory neuropathic pain.
Specific indications for consideration for neurostimulation include:
Complex regional pain syndrome (CRPS).
Failed back surgery syndrome (FBSS).
Postoperative nerve pain condition
Peripheral neuropathic pain
Following a successful trial period, small electrodes are placed near the spinal cord in the epidural space. The electrodes are connected to a small battery device that delivers low-level electrical impulses that interfere with the perception of pain as it travels up the spine or other targeted nerve.
Frequently Asked Questions
What should I expect after the procedure?
If the procedure is successful, you may feel that your pain may be gone or has noticeably lessened. You will experience a fairly constant sensation of stimulation. You may have soreness due to the needles used for a day or two. Generally, the procedure gives a reduction in the amount of pain and may decrease the amount of medications needed.
What should I do after the procedure?
This procedure is normally a day-procedure. Some patients may be kept overnight for observation. If possible, have someone drive you home. We advise patients to take it easy for a day or so after the procedure. Perform your usual daily activities as tolerated by you.
How long will the generators last?
The implanted generators are rechargeable and the charging interval depends on the amount of power required by you to feel comfortable. Recharge intervals are typically every 4 ~ 7 days. The generator has a 10 year guarantee but is expected to last much longer.
