InTENSity Twin Stim III

Two therapies. One pocket-size unit.

Twin Stim III puts TENS and EMS in a single digital stimulator. Switch between them at the press of a button, then fine-tune rate, width and timing on two isolated channels.

It runs on a standard 9-volt battery or the included AC adaptor, and weighs just 0.28 lb, so therapy goes wherever your patient does.

Questions? Answers.

Is it a TENS unit or an EMS unit?

Both. TENS mode is used for pain management, and EMS mode stimulates muscle contractions. You choose the mode on the unit.

Do I need a prescription?

Yes. It is a Class II prescription device, so federal law restricts its sale to, or on the order of, a licensed healthcare practitioner. We may ask for a prescription before shipping.

What warranty does it have?

One year from the date of purchase, covering the device. Accessories subject to normal wear, such as electrodes, are excluded.

One-year warranty from the date of purchase. Federal law restricts this device to sale by or on the order of a licensed healthcare practitioner.
