Peripheral Nerve Stimulation for Nerve Injuries

Peripheral Nerve Stimulation (PNS) method is older than any other neuromodulation technique. Pioneers of PNS experimented on themselves stimulating their infraorbital nerves, and achieving pleasant numbness in the face. Here is how they described the first treatment: "On October 9, 1965, Dr. Wall and one of us (Dr. W.H. Sweet) implanted a pair of silastic ring platinum electrodes around the ulnar and another pair around the median nerve in the arm carrying the wires out of the skin at the mid-forearm. On the median nerve 0.1- ms pulses at 100/s and 0.6 V provoked a pleasant tingling in the lateral three fingers and corresponding hand and stopped the pain in the medial three fingers and hand as well as tenderness in the third finger and palm."

I started using PNS to treat intractable pain 15 years ago. Since I moved back to Canada in 2013, I have done only R&D work to develop new devices. Three of them are already FDA approved, and Health Canada approval is pending. 

I'm excited to have this modality here to make patients' lives better.

One of my patients from Seattle sent me this note a couple of weeks ago: Hello Dr. Gofeld. I'm the patient that you implanted the IPG into the calf of my leg to alleviate nerve pain in my left ankle. The nerve damage occurred during an ankle replacement. You SAVED my life!! Remembering how desperate I was for some solution, remembering being sent to you after a couple different appointments at the U of W, remembering the day that you told me, "I think I can help you". You don't know the impact your care of me had on my life and those around me! At this time, yes, I still use my IPG on a regular basis. My ankle tells me when to turn it on/off..........I find that so interesting. I just really want you to know that you're thought of and I am an eternally grateful former patient of yours. Sincerely, Sue Q"

Pain Specialist, eh?

A pain specialist, a specialist in chronic pain management, an algologist - all these and other definitions of a doctor who deals with individuals suffering from chronic pain do not make sense for the public. Does a family physician treat chronic pain? Yes, of course, as well as orthopedic surgeons, neurologists, oncologists, and the rest of medical specialties. Even dermatologists and ophthalmologists. So what makes this Pain Medicine special? Why can't each and everyone manage the pain of her/his patients? Perhaps, my view is unconventional, but I believe in accountability and commitment to patient well-being. If my esteemed colleagues did the same, many chronic pain conditions would be extinguished. For example, if spine surgeons would commit to staying with their patients, no surgeries for low back pain would ever happen. The reality is different: patients are promised miracles and cure, and then are thrown away back to their family doctors loaded with narcotics and more pain issues than before the surgery. But, let me come back to definitions. Thus, Chronic Pain Specialist is the one who should be finally able to make a correct anatomically sound diagnosis and treat the problem. Unfortunately, patients get to us after months and often years of physical and, subsequently, emotional suffering. When a clear bio-anatomical cause is not addressed, Pain is transformed brain of the sufferer, starting off a vicious cycle of pain-depression-social isolation-drug dependency-pain. Therefore, we, Pain Specialists, should see patients with sciatica, acute back and neck pain, and other conditions, way before orthopedic and other surgeons; we should consult patients with shingles and traumatic nerve injuries way before they are desperate. Pain Specialists should be seen as a new Palliative Care. Just until recently, only dying cancer patients would be referred to Palliative team. With the paradigm shift, these patients are be routinely assessed by palliative care doctors to address their symptoms - pain, fatigue, constipation, etc. It resulted not only in better care, but in significant improvements in the quality of life and, often, survival.
