An average user will get approximately 10-15 uses per pack of the electrodes included with the Twin Stim III, depending on how frequently they are used and for how long, as well as the user's skin type. Once the adhesive gel wears off, you can simply discard the electrodes and begin with a new pack of pads, but note that each unit comes standard with only one pack of four individual electrodes.

Accepted Answer

A: Yes, the InTENSity Twin Stim III is FDA 510K-approved.

Accepted Answer

The InTENSity Twin Stim III is a TENS and EMS/NMES combination unit, allowing the user to be able choose between either TENS (Nerve Stimulation for pain relief) or EMS (Muscle stimulation for rehabilitation and re-education). This unit also runs off of either a 9V battery or an AC Adapter so that you can plug it into a wall outlet and power it that way. The TENS 3000 is a basic, analog, stand-alone TENS unit, and only runs off of a 9V battery.

Accepted Answer

A: The Twin Stim III only allows a user to run a TENS therapy treatment, OR EMS, at one time, not both simultaneously. You can only switch from one or the other.

The Twin Stim III is a combination TENS and EMS electrotherapy device. It does not work like a heating pad. If you are interested in a heating pad, you may want to consider the "Thera-Med Professional Dual Moist-Dry Heating Pad" that we also have available here: http://www.tenspros.com/theramed-professional-dual-mode-heating-pad.html

It is generally not recommended to use an electrotherapy treatment on the face, but please always consult with a doctor/medical professional prior to considering such a treatment, to see if it is right for you. For TMJ, you may also want to ask specifically about Microcurrent vs. TENS vs. EMS.

The final step of the setup cycle, when pressing the "S" button to navigate through each of the treatment parameters, is where you see "0 mA" displayed on the lower left and right-hand corners on the screen. This is for adjusting the pulse amplitude, measured in milliamps (mA), which is the intensity of the stimulation. So when you get to this point of the setup process, you are ready to begin your treatment session by pressing the appropriate Channel Up button(s) to increase the intensity from 0mA to 1mA and so forth, which will immediately activate the treatment timer as well. The intensity is adjustable from 0 - 105mA in 1mA increments. 'Hope this helps!
