Back pain is a common problem for many people these days, isn't it? Sometimes the pain is unbearable. So we are looking for different treatments for it. Today we are going to talk about one such special treatment. That is TENS therapy. You may have heard of it. Let's see what TENS is and how it can help with back pain.
Simply put, what is TENS?
The full name of TENS is Transcutaneous Electrical Nerve Stimulation. Although the name is a bit complicated, what happens in this is very simple. This is a method of relieving pain. It uses very low-voltage electrical currents (mild electrical currents).
Simply put, TENS is a small, battery-operated device. It has wires attached to it and sticky pads on the ends of the wires that you stick to your skin. We call these pads ``electrodes.'' When you put these pads on the area where you have pain, and turn on the machine, a very fine electrical current passes through it into your body.
This subtle electrical current is believed to stop your pain signals from reaching your brain, or at least change the way you perceive pain .
Despite nearly 50 years of research, scientists are still not 100% sure how it works, or if it's even effective. But some doctors and patients say that the treatment reduces pain. Another theory is that the electrical current releases endorphins, which are naturally produced by our bodies. This treatment is used not only for back pain, but also for pain associated with conditions such as osteoarthritis and fibromyalgia.
How to use TENS for back pain?
If you're getting TENS therapy for back pain, you'll place pads (electrodes) on your skin around the area of pain. Then, when you turn on the machine, you'll start to feel a tingling sensation.
If this treatment is right for you, you may feel immediate relief from the pain . However, sometimes the pain may return shortly after treatment. However, some people report that the pain has subsided within 24 hours.
But we need to be clear about one thing. There is not much research support for the effectiveness of TENS as a stand-alone treatment for lower back pain. Some studies have shown that there is no significant difference between TENS treatment and a placebo.
However, some guidelines say that for chronic lower back pain that has lasted more than 3 months, TENS is something that some people may find worthwhile. It can be used as an alternative treatment, especially when conventional treatments such as exercise and medication have not helped. Acupuncture and massage are other alternative treatments.

TENS therapy is generally safe when used correctly. However, it is not suitable for everyone. Therefore, it is very important to talk to your doctor or physical therapist before starting this treatment.

If you use TENS at home...

How do you properly apply pads?
- Apply pads on either side or above and below the area where the pain is most severe.
- You definitely need to use at least two pads . One won't work.
- Leave at least an inch of space between the two pads so that they don't touch each other.
- Do not place pads directly on the spine.
When using it at home, be careful of these things:
- Before applying the pads, clean the skin in the area thoroughly and pat it dry. Do not apply any creams or lotions.
- When turning on the machine , always start at the lowest setting. Then gradually increase the setting to a level that you can tolerate, but still feel a bit harsh.
- Research suggests that you may get more results from using TENS while you are active , rather than while sitting or lying down.
- Do not use TENS while driving.
- Do not use this in the bathroom or bathtub.
- Do not place heating pads or ice packs where TENS is used.
- Do not use TENS while sleeping.
- If you develop any itching, redness, or burning sensation where the pads were applied and it persists for more than 6 hours, stop using TENS and see your doctor.
Are there any side effects of TENS therapy?
Although TENS is generally safe, some people may experience minor side effects.
- Allergic reactions to the adhesive in the pads.
- That subtle electric tickle feels like an unpleasant sensation.
