If you've had physical therapy before, more than likely you may have heard of electrical stimulation. A machine connected to pads to help reduce pain. TENS units have been created for that same purpose, but available to the public for home treatment. TENS stands for Transcutaneous Electrical Nerve Stimulation.
It is a small, lightweight, handheld device that produces electrical currents to electrode pads that attach to your skin. You will feel non painful, tingling sensation.
It works by delivering small electrical impulses through electrodes attached to the skin. Theses impulses flood the nervous system, reducing ability to send pain signals to the spinal cord and brain. It can also help stimulate the production of endorphins.
Theres a lot of positives to using a TENS unit. For obvious reasons, it can help reduce pain. There is little to no side effects when using a TENS unit. It is a drug-free, natural relief, not needing to take any pain meds. It is non invasive and can be easily used at home, though it is portable and can be used anywhere!
Electrodes can be placed almost anywhere on the body for multiple pain points, however there are areas where they should never be placed. That includes, open wounds, areas of infection, directly on the spine, eyes, brain or heart, on a pacemaker, over tumors, and on epilepsy patients.
You also want to be cautious of any skin irritation. That is what it is recommended to use a TENS unit for about 30 minutes, with about a 30 minute break in between uses. Can be used as tolerated, but more recommended for 3-4x per day.
