One major reason why neuromodulation devices aren't more widely used is because legacy products are still expensive, costing anywhere from several hundred dollars to tens of thousands of dollars. Insurance covers the cost of some therapies, but not all. Naturally, it is also easy for insurance companies to hide behind the National Coverage Determination (NCD) for Electrical Nerve Stimulators.
Today, there are invasive or non-invasive medical devices that promise to fight pain without opioids and the cost of these devices are coming down rapidly. Further, full-featured, fully-programmable platforms accelerate medical research without having to invest top dollars and time to develop purpose-built hardware.
With tens of thousands of people dying every year and with lower cost of modern devices, it is time to say "enough is enough" to opioid addiction. We must stop thinking of pain control as just being about opioid medications.
