A Closer Look at TENS Devices
Those living with chronic pain know that there isn’t a one-size-fits all approach to finding relief. While there are myriad options available, it can be challenging to find the right combination of therapies that will fit within an individual’s lifestyle while alleviating pain. One treatment modality that chronic pain sufferers may discover during their research is transcutaneous electrical nerve stimulation, or TENS.
What is TENS?
Transcutaneous electrical nerve stimulation (TENS) is the delivery of electrical current across the surface of the skin to activate the underlying sensory nerves and provide pain relief. The technology was originally developed in the 1970s as a screening technique for predicting which chronic pain patients would respond to implantable stimulators. However, many patients were getting relief from TENS alone, leading to the adoption of this technology as a pain relief therapy in and of itself. TENS typically is delivered with a small electronic machine that generates the electricity which is then delivered through a set of connected electrodes. A user places the electrodes on the skin – most often at the area of pain – to facilitate electrical current to flow into and out of body. The stimulation current from the TENS device activates electrical impulses that travel along the nerve fibers.
Navigating the TENS Spectrum
There are a variety of TENS devices available to treat many different forms of pain. People often ask if Quell is a TENS device and, if it is, what distinguishes it from other TENS devices found in pharmacies, retail stores or in clinician offices. While Quell and other devices are all considered TENS devices, they should be thought of as sitting on a neurostimulation spectrum, rather than within a single category.
At one end of the spectrum, are traditional over-the-counter TENS devices that offer low dose electrical stimulation and are designed for short term use. At the other end of the spectrum, are implantable spinal cord stimulators that are surgically placed adjacent to the spine to provide continuous pain relief for severe intractable chronic back pain.
So where does Quell fall along this spectrum? Quell was designed to deliver stimulation throughout the day while active and at night while sleeping thanks to the wearable, non-invasive form. Quell is 3X’s more powerful than ordinary over the counter TENS devices.
Should you try TENS?
Anyone living with chronic pain should consider TENS devices as a part of their treatment toolbox. With so many options available, understanding the differences between them should help make the process of finding the right device or therapy easier. It is important to remember that not all TENS are the same, and recent innovations like Quell hold promise to make a meaningful impact on chronic pain.
