FAQs: TENS | Avail®

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.

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

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

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.

To clean the NON-ADHESIVE side of the pads, wipe the surface with a soft cloth moistened with water or a neutral detergent, then wipe the surface with a dry, soft cloth to remove extra water.

First, turn the device off. Clean the device with a lightly moistened cloth and wipe gently. DO NOT use chemicals (like thinner or benzene). DO NOT let water get into the internal area of the device.
