What is a TENS unit?

A TENS (Transcutaneous Electrical Nerve Stimulation) unit is a battery-powered device that delivers small electrical impulses through electrodes placed on the skin. It's used for pain relief by blocking pain signals to the brain and stimulating endorphin production.

Consider these factors: number of channels (2 or 4), intensity levels, pre-programmed modes, rechargeable vs battery-powered, and your specific pain condition. For most users, a dual-channel rechargeable unit with 10+ modes offers the best value.

Question 3

Are TENS units safe to use at home?

Accepted Answer

Yes, TENS units are FDA-cleared and safe for home use when following manufacturer guidelines. However, they should not be used by people with pacemakers, during pregnancy, or on certain body areas like the throat or head.

Quality TENS units range from $20-100. Budget options ($20-35) work well for occasional use, mid-range units ($35-60) offer more features, and premium units ($60-100+) provide clinical-grade performance.
