TENS stands for Transcutaneous Electrical Nerve Stimulation. Electric current of low voltage is used to relieve pain. The device is small and battery-operated. A belt is used to anchor the device that has two electrodes connected to it. The electrodes transfer current to the skin from the machine.
What Does a TENS Unit Do for Back Pain?
By delivering a sensation that is non-painful to skin around a pain site, the hope is to disrupt the cycle of pain. The way pain is processed is modulated. The plan is to deliver electrical stimulation from the TENS unit often enough to trigger endorphins. Endorphins are natural pain killers in the body that give one a sense of well-being.
Study is not complete on the success of the device. Researchers have found TENS was useful in controlling chronic pain in some individuals. Fortunately, trying the treatment has very few side effects. Drowsiness does not occur. There is no interaction with other medications. The device can be applied easily and be worn while doing most activities for pain management.
People who use the device, with some success, may be a little over optimistic. Many have over-exerted themselves because of the pain relief experienced and caused the pain to become worse. New users are most guilty of this misconception.
There are people who should probably not use the TENS machines. People that have a pacemaker, have cancer, are pregnant, or have poor sensation should not use pain relief products like this.
Systemic drugs affect the whole body. The electrotherapy provided by a TENS device targets pain at the site it occurs. Medical practitioners, doctors, pain clinicians, physiotherapists, and sport coaches have recommended its use for acute and chronic pain.
Individuals have had variable results. For some, there is effective reduction or elimination of pain that lasts longer than the stimulation period. The success rates of others was found to be pain modified only while the stimulation occurs.
How to Use a TENS Unit for Back Pain
TENS units are used for all kinds of pain. Electrode placement depends on the location and type of pain. Covering or surrounding the painful area is one way of doing TENS unit therapy. Arthritic joints and spasmodic or painful muscles benefit from this kind of treatment. Nerve pain may be treated by placing the electrodes between the brain and the injured nerve.
Placement of the electrodes is important. Pain may not be decreased if the electrodes are placed incorrectly. The pain could be increased. Putting electrodes near the eyes or over nerves that extend from the neck to the brain or throat should not happen.
The device should be fully charged before starting a TENS unit treatment. The battery pack should be tested. Control knobs should be turned to the “OFF” position before starting. One knob controls the strength of the electrical signals. The other controls the speed of the signals.
The area where electrodes are to be placed should be cleansed with rubbing alcohol and then dried. A thin gel coat should be applied to the electrode bottoms. The gel aids in getting the electrical signal to the nerves beneath the skin.
After placing the electrodes on the skin, use a sticky patch or tape as electrode covers. The adhesive will keep the electrodes firmly attached to the skin. The electrode wires have pin connectors at the ends that are to be hooked onto the electrodes. Then they are plugged into the unit.
Slowly turn knobs to the settings recommended by a caregiver. A tingling feeling should be noticed. Place the TENS unit in a pocket or hook it to a belt. The caregiver will tell the user how long to use the device.
Twitches of the muscle may indicate the signals are too fast or strong. No feeling might be an indication of a signal that is too slow or weak. The TENS unit should not be operated in water or during sleep.

The first point in favor of the device is that professionals such as doctors, practitioners, physical therapists, trainers, and coaches have given the product positive reviews and recommend its use.
When one has to seek professional help from a back pain specialist, often electrotherapy is part of the treatment. Purchasing the device makes that same kind of therapy and relief available outside the rehab facility. The ease of use is also a selling point.
