Has Spinal Cord Stimulation Improved To The Point Where It Provides A Viable Alternative For Chronic Nerve Pain?

Today's post from (see link below) reports on an interesting discussion about Spinal Cord Stimulation as being a means of reducing chronic nerve pain. Spinal Cord Stimulation has been around for years of course but has suffered from poor results and neuropathy patients and doctors alike have become reluctant to offer, or try it. In these days of looking for opioid alternatives, it's logical that SCS methods will be re-examined and that's exactly why these specialists got together to discuss the issue. It's somewhat ironic that research into treatments for neuropathy has been stagnant for decades but the minute that opioids become a 'hot' issue, then research into pain relief goes into overdrive. That said, nerve pain patients mustn't grumble: at least efforts are now being made to find alternative solutions. However, this discussion concluded that patient reluctance regarding SCS is based on past experiences with older technology which rarely worked as was hoped. The physicians maintain that the technology has now moved on to the point where success in controlling pain via electrical stimulation is now much more likely. The problem lies in how you measure pain and results and this is a whole new ball game because pain is so subjective and by asking a patient to point to a smiley face to indicate their pain levels, you might as well lick your finger and stick it in the air. The conclusion must be that if SCS technology is so much better, then evaluation methods need to drastically change to catch up. Interesting read.

The Case for Spinal Cord Stimulation in Chronic Pain

Expert physicians gathered in a round table event to discuss Spinal Cord Stimulation as a treatment for chronic pain.


With opioid abuse posing a national health crisis, the American College of Physicians recently issued a new guideline to promote treatment alternatives like acupuncture and yoga ahead of opioids on the treatment continuum for low back pain. But, many pain specialists believe alternative therapies like these don’t provide adequate symptom relief, leaving patients to look toward opioids as their only option.

A group of the nation’s leading experts in spinal cord stimulation (SCS) convened for a roundtable discussion at the 2017 North American Neuromodulation Society Annual Meeting to discuss why SCS should be used earlier in the treatment continuum and how it can play a role in addressing the ongoing opioid epidemic.

What becomes immediately apparent on reading the executive summary from the discussion, is that all 6 participants shared the view that SCS should play a much greater role in the management of chronic pain. There was unanimity of opinion that opioid use is problematic, carrying risks of misuse and abuse, while also only being “50% effective in 30% of patients treated.”

Management of patients off their opiates is of course another problem for the clinician, withdrawal being a weaning process and requiring an educational approach. The consensus seemed to be that SCS should be positioned ahead of opiates in the pain treatment continuum.

So why isn’t that already the case? Well it seems that the early days of the therapy weren’t quite as successful as today, which may have spawned resistance in both the clinical and patient community. The panel took this subject on too, suggesting that older technologies presented difficulties targeting specific nerves, while today’s is considered “not the same therapy” and “capable of yielding 100% pain relief.”

The final topic was the SCS patient pathway, the group concluding that the subjective nature of current pain scoring methods meant that their use should not be the only factor. The group expressed a desire to work with medical societies and regulatory bodies to develop a more nuanced standard for measuring patient outcomes.

Selected Physician comments 

Dr. Mark Wallace, chair of the division of Pain Medicine in the Department of Anesthesiology of University of California at San Diego stated; “In my 25 years’ experience, all of my patients reduced their opiates once I put a spinal cord stimulator in them. Most of them completely go off of the opiates. So what we need to do is we need to position the neuromodulations before opiates, and we need to change the pain treatment continuum and get it earlier in the treatment continuum so we can keep patients from starting the opioids in the first place.”

On the subject of the modern SCS therapies, Dr Julie Pilitsis, professor of neurosurgery and of neuroscience at Albany Medical College and Chair of the Department of Neuroscience and Experimental Therapeutic, stated; “I would just like to encourage people…that may have had a negative experience with spinal cord stimulation 20 or 30 years ago to come back to the therapy. It is not the same therapy. We have so many more capabilities. We can help so many more people.”

On the need for a new approach to scoring patients for pain levels, Dr Simon Thomson, consultant in pain medicine and neuromodulation at Basildon and Thurrock University NHS Trust, UK, stated; “I think most people would say in something like chronic pain, it’s plainly ridiculous just to have linear pain scores to define, if you like, the suffering that this patient and those around them are going through … the measure that seems to best define what we’re looking at achieving in our patients is a health-related quality of life measure.”
