He had endured pain in his feet for decades, and it was only getting worse.
BEST SPINAL CORD STIMULATOR 2021 TRIAL
Raleigh resident Kerry May was running out of options to treat his diabetic neuropathy foot pain when he was given the opportunity to participate in a clinical trial studying the effectiveness of spinal cord stimulation. However, until recently, it had not been well studied for treating neuropathy of the feet caused by diabetes.ĭiabetic neuropathy has long been treated with a variety of drugs, but the use of these medications is waning due to side effects, risk of dependency, and lackluster results, leaving millions of people with few treatment alternatives. The technology has been used for decades to treat back and leg pain.
BEST SPINAL CORD STIMULATOR 2021 GENERATOR
It consists of two parts: a small pulse generator that is implanted under your skin, and two small wire leads that are placed near specific nerves along your spine. Larger studies with long-term follow-up are needed to elucidate the durability of pain relief and the precise mechanism by which combined subperception and paresthesia based SCS may improve overall patient outcomes.īack Pain Chronic Pain Combination Multi-wave Form Complex Regional Pain Syndrome Failed Back Surgery Syndrome Paresthesia, Subperception Neurostimulation Spinal Cord Stimulation.A spinal cord stimulator is like a pacemaker for diabetic neuropathy pain. The mechanism of action is unclear though there may be an additive and/or synergistic effect of the two waveforms delivered. Our findings suggest improved pain relief in patients who had previously had good results with paresthesia based therapy and subsequently underwent IPG exchange to a device capable of delivering combined sub-perception stimulation. 80% of patients reported an improvement in the quality of paresthesia over traditional SCS therapy, and in most patients, this translated to significantly improved pain control. The average NRS decreased from 7.47 with traditional SCS to 4.5 with combination therapy. Secondary outcomes included paresthesia changes, which included the subjective quality of sensation generated, the overall subjective coverage of the painful region, subjective variation of coverage with positional changes, and global perception of the percentage improvement in pain.īased on our clinic registry, 30 patients were eligible for IPG exchange, 16 were consented for follow up and underwent an exchange, and 15 were available for follow up four weeks following. Their pain was assessed on each follow up using a Numerical Rating scale (NRS) the primary outcome was the change in NRS after four weeks from the exchange day. Patients were assessed immediately following the exchange and four weeks later using a telephone survey. These patients presented for implantable pulse generator (IPG) replacement based on battery depletion with an IPG capable of combined sub-perception and paresthesia based SCS therapy.
This is a prospective observational trial examining patients who had previously been implanted with paresthesia based SCS for failed back surgery syndrome (FBSS) or complex regional pain syndrome (CRPS). This study aims to determine the effect of superimposing sub-perception stimulation in patients who previously had good long-term relief with paresthesia. Traditional SCS relies on low-frequency stimulus in the 40 - 60 Hz range causing robust paresthesia in regions overlapping with painful dermatomes.
Spinal cord stimulation (SCS) is an effective therapy for otherwise refractory chronic pain. Chronic back and neck pain affects 20% of Americans.
