Most frequent questions and answers
Tens units have different adjustable settings to control amplitude (intensity) of stimulation by controlling the voltage as well as current and pulse width (duration) of each pulse. Electrodes are placed at specific sites on a user’s body depending on the physical location of their pain. The current travels through electrodes and into the skin stimulating specific nerve pathways to produce a tingling or massaging sensation that reduces the perception of pain. When a Tens Unit is used as directed a T.E.N.S. is a safe, noninvasive, drug-free method of pain management. A Tens Unit is used to offer a better quality of life for people with pain. There are two ways to explain how a T.E.N.S. successfully decreases or eliminates pain.
Normally when you perform an exercise, your brain sends a message through your spinal cord to nerves indicating muscles to contract. EMS neuromuscular stimulator uses electrical impulses to stimulate the nerve axons. These impulses reach the nerve axons, signaling the muscles to contract and relax rhythmically as instructed by the EMS unit. EMS electro muscle stimulator actually stimulates muscles that you cannot normally exercise voluntarily. This allows you to train muscles that may normally have little activity.

A Tens Unit, or transcutaneous electrical nerve stimulation can help back and neck pain that may be caused by trauma or continual strain. The body responds to such pain or injury with muscle guarding, an attempt to immobilize the painful area by tightening the muscles surrounding the injury. Muscle guarding impairs circulation in the affected area.

The decrease in blood supply leads to a decrease in metabolism with an accumulation of waste products. TENS therapy (transcutaneous electric nerve stimulator) can help break this pain cycle and aid in the normal healing process.

EMS Muscle stimulators, or Electrical Muscle Stimulation are used to relieve pain, reduce spasms and edema, tone weak muscles and assist in the healing process. Known to ease muscle tension, stiffness in joints or back areas, and known for increasing motion restricted from disuse or atrophy, electronic muscle stimulation can also increase local blood circulation.

EMS Units run at intensities from 1 to 130 Mega Hertz. Where a tens unit is designed to help relieve certain types of chronic and acute pain by stimulating the nervous tissue, an EMS is designed to treat more of the muscle area than the nerves. This can help reduce swelling and muscle inflation which can have a negative effect as strained muscles can pull joints out of place.

Check with your doctor or physical therapist to help determine what features you need to achieve the best results from TENS or EMS therapy for your particular condition. Some key features to look for in all units include battery life, controls and width control. Some less-expensive TENS units use regular disposable batteries. In many cases, the higher cost of a unit with a rechargeable battery is easily justified by the savings from recharging the unit instead of buying new batteries. High-tech machines like TENS units tend to wear out disposable batteries quickly.

A prescription is required by some states to own a TENS unit. You should check with your doctor to see what the laws and regulations are. We do not require a prescription to purchase ones of our units, but you may need it for your records.
We do accept healthcare related debit cards for purchases such as HSA and FLEX cards. These are healthcare related expenses, such as purchasing a blood pressure monitor at a pharmacy, accordingly you can avail the use of same.
All our controllers, accessories and consumables are FDA approved class II. Meaning that your don’t need a prescription from a practitioner.
Our electrodes, are engineered to last long (reusable up to 200 applications), hydrogel adhesive (Don’t degrade and do not require an adhesive). They have the standard button connector and any of the electrodes should be compatible with your unit as long as they have standard connectors.

CLICK This link has an electrode placement chart which also includes electrode skin care and application of re-usable self-adhesive electrodes.

There are many factors that can influence how long they last. For example: • How long are these electrodes used at a time (30 minutes or 8 hours). If they are used for a couple of hours a day, we recommend using 2 sets of electrodes. Use the first set for the first day and the second set for the second day. This will give the first set about 24 hours to completely dry which will expand the usage time. Repeat these steps by rotating the 2 sets. • If you have a lot of body hair they will not last as long as if they are placed on bare skin. If possible place them on bare skin. • During a hot summer day you can sweat more than during a winter day. Getting the electrodes wet will shorten their usage. Allowing them to dry for 24 hours will help extend their life span. • It may be helpful to improve repeated application by spreading a few drops of cold water over the adhesive and turn the surface up to air dry. Be careful not to over-saturate as too much water can reduce the adhesive properties. As you can see there are many factors that can influence the usage time. However, following the instructions on the electrode bag will help extend the usage of these electrodes.
Electrodes should be replaced when the electrodes are no longer sticking firmly to the skin, have been re-applied more than the suggested amount of uses or when the electrode is no longer conducting effectively.
You cannot use a unit if you have a Pacemaker or Implantable Cardioverter-Defibrillator.
No, you cannot use a unit while pregnant.

You can apply the adhesive electrode pads to anywhere on your body, except the heart and brain area, the front of the neck, or directly on an open or bleeding wound.

Ensure that the protective plastic film covering the electrode pad adhesive surface has been removed. Your pads may have dried out. The adhesive gel on the electrode pads should be moist. The pads will eventually dry out from use and will need to be replaced. To extend the life of your pads, place a few drops of water on each pad after use and immediately apply the protective film to prevent them from drying out or picking up dirt. For best results, replace your electrode pads often.

Worn out electrode pads are the most common cause. 
Try replacing your worn pads with a new set. The sensation should be mild and soothing, not stinging. Electrodes pad must be moist and sticky to work. Pads that have dried out may produce a weak and stinging sensation. Try placing a few drops of water onto the pads. Wipe the surface with your finger, allow any excess water to dry and then apply immediately to your skin. Make sure that the electrode pads are making firm and full contact with your skin.

 For best results, replace your pads often.

  1. Check for a firm wire connection on the pads and make sure the plug is securely plugged into the post of the unit.
  2. Turn the unit off before adjusting or plugging in the lead wires to prevent sudden, intense stimulation.
  3. Make sure that the battery has been charged.
  4. Check to ensure the electrode pads are moist and not worn out.
  5. Turn the unit off, then turn back on again.
Please make sure both electrode pads are attached to the same person’s body, in order to feel the sensation.

No, unfortunately, muscle stimulators should not be used by those with a pacemaker or defibrillator.

You can use it as often as you like. An average alleviation session should last between 10-40 minutes. We recommend you use your muscle stimulator a minimum of 20 minutes to achieve results but not more that 60 minutes on the same area to prevent muscle fatigue. We recommend using your device 1 to 3 times per day for best results.

Our devices are cleared for OTC use and are not intended to replace any professional health care.

 When in doubt, we recommend that you consult with your health practitioner first.
