TENS (Transcutaneous electrical nerve stimulation) uses electric current offered by a device to stimulate the nerves for healing intentions. Several companies began manufacturing TENS units after the commercial success of the Medtronic device became known. TENS is a non-invasive, safe nerve stimulation intended to reduce pain, both acute and chronic. In this case, we refer to wireless, portable stimulators used to help with lower back pain. The unit is connected to the skin using two or more electrodes or semi adhesive pads. Then you select your intensity and type of treatment, and the machine does the rest.
Some therapists might use EMS, but when treatment is for lower back pain, you do not want to contract the muscle. And with the TENS machine, you will not. TENS is for surface nerves that help increase the area’s blood circulation and helps control the lower back pain.
A modern-day TENS machine, the iTENS, let you use one channel with two electrodes called the ‘wings’, and you may want to choose large kit TENS for broader lower back pain. The good thing about TENS is that it is general to the pain area. Just put the TENS unit where you feel the pain.
How Should You Adjust the Stimulation?
The intensity of the stimulation should be determined by starting with low power and increasing it until an adequate level is reached. The amount of stimulation varies with the location of the pain and the individual who is using the machine. Pain relief lasts after the device is turned off, and most people will use the machine for about 30 minutes at a time once or twice a day. It is safe to use for as long as you feel you need to.
TENS therapy has become a reasonably routine sort of treatment for pain and rehabilitation for lower back pain. The majority of patients who receive TENS therapy report substantial levels of pain relief. Many find the treatment extremely effective, and most physical therapists agree that it will shorten healing duration significantly. It is also an excellent alternative to drug treatments.
