What is a TENS Unit?

It's a device that sends electrical pulses to your body through sticky pads. Although it sounds like magic, it's not. A transcutaneous electrical nerve stimulation (TENS) unit is the most common form of electrotherapy for managing various types of acute and chronic pain. TENS units are small, battery-powered devices that administer mild shocks through sticky tens unit pads (also called electrodes) that connect to the skin. These electrodes connect to the TENS unit through lead wires. However, wireless TENS units have become popular.

Do TENS Units work?

TENS therapy is one of the most used forms of not just electrotherapy, but pain management for chronic and acute pain. Before TENS 7000 was an OTC TENS unit, it was the most prescribed TENS unit by professional doctors and physical therapists. It may be a shock that there has been no conclusive research or clinical trials determining if TENS therapy is a reliable pain relief treatment. However, there have been tests done stating a positive resultof pain relief.

How Long does TENS Therapy Pain Relief Last?

Pain relief from TENS therapy has shown varying results with aid lasting as short as 5 minutes and up to 24 hours. There's no definite answer as to why this is, but one hypothesis is that pain relief depends on the pain type as well as the level of pain. Acute pain is going to require less treatmentcompared to more severe and chronic pain types. Tips for consistent pain relief with TENS therapy include continuously using the TENS unit as well as changing the electrode positions and intensity of the treatment.

How often can you use a TENS unit? Can you use a TENS unit too much?

Because of the low-risk treatment of TENS units, you can use them for as long and as often as needed. Professional doctors and physical therapists usually recommend pain treatment sessions of 30 minutes at a time with 20-minute break periods in between. If over-used, some soreness may occur while having the settings up too high can lead to uncomfortable muscle twitching. Some have reported a burning sensation on the skin when over-treating the affected area.
