The Role of TENS Units in Pain Management at Home

TENS units

According to the Centers for Disease Control and Prevention (CDC), approximately 51.6 million Americans live with high-impact chronic pain which lasts for more than 3 months. The severity of this pain is significant enough to cause a hindrance in day-to-day activities. In many of these cases, people approach a healthcare facility to obtain a suitable prescription. However, medication is not the only way out. Diversity exists in the types of management techniques that specialize in the reduction as well as complete relief from pain. One such treatment option is the TENS unit, an FDA-approved system, which is being employed for the management of pain. Let us understand what exactly TENS units are and how it works in alleviating pain.

What is a TENS Unit?

TENS, an abbreviation for Transcutaneous Electrical Nerve Stimulation, is a compact, lightweight, and battery-powered pain relief therapy. It works by sending low-voltage electrical signals near the nerves with the aim of blocking them completely or simply altering the pain perception. The procedure is often helpful in pain management during osteoarthritis, fibromyalgia, and tendinitis. Being available over-the-counter (OTC), the TENS unit can be purchased from your nearby pharmacy without a prescription. 

How Does a TENS Unit Work?

The perception of pain is generated by the nerve cells which are present deep into the muscles. Therefore, the TENS unit pain relieving system works by sending electrical signals to these nerve cells which in turn changes the way they perceive pain. As a result, the level of pain felt by the body is reduced and the patient experiences relief.

In addition, the TENS unit system also elevates the blood levels of endorphins which are our body’s natural pain relieving chemical agents. When the level of endorphins is increased, the system thus activated manages the pain and helps the body feel relaxed.

Applications of TENS Unit

● Pain in the back

● Peripheral artery disease (PAD)

● Diabetes-related neuropathy

How to Use TENS Units in Home Settings?

In-home settings, TENS units can be used by following the given guidelines:

● Make sure the TENS unit is fully charged.

● Clean the area of the skin where the TENS unit electrodes are to be attached using rubbing alcohol and let it dry.

Check if the two control knobs of the TENS unit are switched off. If not, switch these off before placing the electrodes on the skin.

● With the aim to transfer electrical signals to the nerves, put a thin coat of gel on the bottom of the electrodes and place them on the skin.

● For covering the electrodes, use medical tape or a sticky patch. This prevents the accidental falling or displacement of the electrodes.

● Attach the pin connector at the end of the electrode wires to the electrodes followed by plugging the electrode wires into the unit.

● Once the electrodes have been placed, turn the control knob on. The patient should feel a tingling sensation which indicates proper placement.

● After making sure that the device is working properly, the TENS unit device should be hooked to the patient’s belt or in a pocket.

For How Long TENS Units Can Be Used?

When it comes to duration, TENS units can be used as many times as the patient needs. Each cycle can be extended up to 60 minutes. However, guidance should be taken on the frequency and duration of usage of TENS units from one’s healthcare provider.

Precautionary Measures for Using a TENS Unit

While using a TENS unit, the following measures should be taken for safety as well as obtaining optimal results:

● Make sure the signal is neither too strong to cause muscle twitching nor too weak to not even cause the tingling sensation.

● For each treatment, the electrodes should be slightly moved from their place. This practice helps in the prevention of skin redness as well as itching.

● Before placing electrodes on the skin, new gel should be put below them each time.

● While wearing a TENS unit system, one must avoid going near water or sleeping with the system switched on.
