What is the difference between TENS Therapy and Microcurrent Therapy?

TENS is a therapy that has been used for over 30 years by medical professionals, such as physical therapists and chiropractors.  Our TENS devices have various modes which use different methods of moving the electrical currents throughout the muscle in order to administer the treatment. Microcurrent is a therapy that applies extremely small (less than one microampere) electrical currents to the nerves using electrodes placed on the skin.

Can the devices be used separately?

These devices can be used separately. Additionally, Device A can administer a different treatment type and length than Device B.

If treating two different pain locations on the body at once, how far apart can the two separate pads get to each other?

If doing two therapies, the pads should be a minimum of one inch apart from each other.  The pads should never touch or overlap.

What is the recommended time I should use for a treatment?

It is recommended that one session using either the TENS or Microcurrent should last 30 minutes. Treatment times up to 60 minutes for TENS and 180 minutes for Microcurrent are an option given within the device as well.  The maximum amount of TENS treatments you should have in one day is three, while you can do an unlimited number of sessions in a day of Microcurrent.
