A. TENS is an acronym for Transcutaneous Electrical Nerve Stimulation. A TENS unit sends electrical impulses through the skin (transcutaneously) to stimulate nerves and block pain signals being sent by the injury site.

A. While a TENS unit is used primarily for Pain Management, an EMS (Electrical Muscle Stimulation unit) is used for muscle re-education and strengthening such as after an acute injury or surgery. An Electrical muscle Stimulator sends electrical impulses similar to the signals sent by the brain to cause muscle contraction/relaxation.

A. We do not accept or bill insurance. However, when you purchase any of our products you are provided with the paid sales receipt and the necessary CPT codes (billing codes)  to submit to your insurance company on your own behalf. If you cannot purchase out of pocket and need insurance billed, please call us at 1-866-449-1010 for a referal to one of our partner companies to handle this for you.

Orders placed on Friday after 12 noon or on a weekend or holiday will ship the next business day. If you are a patient in the U.S. ordering a TENS unit, EMS unit, Ultrasound, or other Class II medical device that requires a prescription, we cannot ship your order until we receive a copy of your prescription.

A. We offer a 30 day satisfaction guarantee on our products and most of our TENS and EMS units are backed with a 3 year warranty against defects (see specific item for details). We cannot accept returns on opened packs of electrodes (replacement pads) due to cross-contamination risks. For full details on our return policy please see Returns.

A. The placement of electrodes can be one of the most important parameters in achieving success with Electrotherapy. However, every patient responds to electrical stimulation differently and your needs may vary from someone else's. Check with your doctor, chiropractor, or therapist first to see if he or she has recommendations for your specific case. Additionally, our electrode placement chart is a good starting point but it IS safe to experiment with the placement. Once an acceptable placement has been achieved, record the electrode sites in a notebook or your device's manual for future treatment. Never place electrodes on the front of the throat as spasm of the Laryngeal and Pharyngeal muscle could occur. Electrodes should not be placed over the eyes, in the mouth, internally, or such as to flow current

A. Electrodes should be stored in the resealable bag in a cool, dry place. Do not store electrodes in the refrigerator as this can dry them out. The life of electrodes varies depending on skin conditions, storage, amount of use, type of stimulation, and stimulation site.
