What are TENS Pads?

TENS pads, also known as electrode pads or TENS electrodes, are essential components of a TENS (Transcutaneous Electrical Nerve Stimulation) machine. These pads are typically made of a conductive material and are attached to the leads of the TENS unit via wires.

They serve as the interface between the machine and the user's skin, delivering electrical impulses to the targeted area for pain relief or muscle stimulation. These pads come in various shapes and sizes and are designed to adhere securely to the skin.

There are also silicone rubber pads available for individuals with sensitive skin or allergies. Secured by the bandage tape, these non-sticky rubber pads are reusable and offer a comfortable alternative for those who may experience irritation from adhesive materials. 


Choosing the Right TENS Pads

When choosing TENS pads, consider factors like adhesive quality, size, and shape for optimal therapy. Look for pads with a durable adhesive that stays sticky even after multiple uses like adhesive hydrogel and a design that ensures comfort with no biting edges. For individuals with skin allergies, consider hypoallergenic adhesive options for added safety and comfort.

Make sure they're compatible with your TENS machine and are suitable for your skin type. Remember that there are different connection types that are available in the market such as press stud and pin connectors of varying sizes.

Follow proper care instructions to maximize their lifespan, replacing them approximately every 30 days. 


Benefits of Choosing the Right Shape and Size

Choosing the right shape and size of TENS pads is important for making your therapy sessions as effective as possible, when the pads fit just right, they cover the area you need to treat perfectly, spreading out those electrical impulses to hit all the right spots and tackle your pain or muscle tension head-on. 

Plus, with the pads snugly in place, you'll feel way more comfortable during your session, without any annoying shifting or irritation. And let's not forget about versatility–having different shapes and sizes means you can treat all kinds of body parts and conditions with ease. So, whether it's targeting a specific muscle group or soothing a tender spot, getting the right pads means a smoother, more effective therapy experience overall.


How to Use Electrode Pads correctly?

Proper use and maintenance of electrode pads are crucial for maximizing the effectiveness and comfort of TENS therapy. Here's a guide on how to use electrode pads correctly to ensure optimal results:

Skin Preparation 

  • Ensure the skin in the treatment area is clean, dry, and free from any lotions, oils, or powders before applying the electrode pads. These substances can reduce the stickiness and conductivity of the pads.
  • For contact and conductivity, ensure the treatment area is free from body hair. Shaving may be required to achieve optimal results.
  • Consider using specialized TENS wipes or alcohol swabs to ensure thorough cleaning and optimal pad adherence.

Pads Maintenance

  • Handle the electrode pads gently, avoid pulling on the wire connections.
  • If the pads become less sticky, clean them with a moist cloth to remove any dirt or oil buildup.
  • Avoid using materials that can leave residue, such as paper towels, and do not oversaturate the pads with water.
  • It is highly recommended that only one person uses the pads to avoid cross-contamination.

During Treatments

  • Hold electrode pads lightly at the edge when applying or removing.
  • Ensure proper placement of the electrode pads directly across or as close to the area of pain as possible. Please refer to the electrode pads placement chart for various types of pain. 
  • Use two or four pads simultaneously for optimal effectiveness.
  • Adjust the distance between pads or their direction to alter the electrical sensation as needed for comfort.
  • The pads should never touch each other, but they also shouldn't be too far apart.

Between Treatments

  • Remove the electrode pads gently from the skin.
  • Spray water on the pads before putting on the plastic sheet.
  • Store the pads on their storage sheet or in a ziplock bag to prevent them from drying out.
  • Avoid storing pads in extreme temperatures or exposing them to direct sunlight.

After Treatments

  • Check the skin for any signs of irritation or redness. Discontinue use if irritation occurs.
  • Consider applying moisturizer or soothing gel to the skin if necessary, especially if any redness or discomfort is present.


  • Keep electrode pads in a cool, dry place away from direct sunlight.
  • Ensure they are stored flat to maintain their shape and adhesive properties.
  • Avoid storing pads in the refrigerator or freezer, as this can affect their performance.

I am experiencing minor skin irritation from the pads, am I doing something wrong?

To prevent skin irritation from electrode pads, it's essential to maintain proper hygiene and periodically check the skin during prolonged use. Before applying the pads, ensure the skin is clean by washing it thoroughly and during the session, check the skin underneath the electrode pads every ten minutes to ensure there is no irritation developing. This proactive approach helps to identify any potential issues early and allows for timely adjustments or removal of the pads to prevent discomfort or irritation.

For individuals with sensitive skin, on the other hand, consider using rubber pads without adhesive gel as an alternative. These pads are designed to be gentle on the skin and may help alleviate irritation.


How long will the Tens electrode pads last?

The lifespan of TENS electrode pads can vary depending on several factors, including frequency of use, skin type, and how well they are maintained. On average, when the maintenance instructions mentioned above are followed properly, electrode pads may last for approximately 20 to 30 uses, but this can vary. 


Are the electrode pads disposable?

Most pads are disposable but some, such as silicone rubber pads, aren't. Typically, pads with adhesive gel have a lifespan of around 20 to 30 uses.. Poor-quality pads, on the other hand, may have a shorter lifespan due to factors like lower adhesive quality or material durability.


Can electrode pads be used by more than one person?

No, electrodes should not be used by more than one patient. According to FDA regulations, electrodes are labeled for single-patient use only to ensure proper hygiene. Sharing electrodes can lead to cross-contamination, posing a risk to individuals' health. While some electrodes are labeled as multi-use, they are intended for single-patient use to prevent the spread of contaminants. 



Is the pad’s gel hypoallergenic?

Although our electrode pads and the gel used on them are not labeled as “hypoallergenic,” we made sure our Silicone Rubber Electrodes Pad is specifically designed for sensitive skin. This option is ideal for individuals who may have allergies or sensitivities to the sticky gel itself. 

In addition, according to the FDA, there are also no Federal standards or definitions that govern the use of the term "hypoallergenic." The definition of hypoallergenic is “less likely to cause an allergic reaction than other comparable goods.” Since everybody is different, there is no scientific formula to measure or test this.


Do your pads contain latex? 

No, our pads are latex-free. Latex allergy can cause itching, skin redness, hives, or even life-threatening anaphylaxis, with symptoms like difficulty breathing and swelling. Caremax prioritizes comfort and reduces the risk of allergic reactions by eliminating the presence of latex in our products. 


How to make the pads sticky again?

To restore the stickiness of your electrode pads, gently brushing clean tap water onto the pads in one direction with a clean toothbrush and allowing it to sit for a few minutes, the gel will absorb the water, exposing their stickiness. 


What are the areas to avoid when applying pads?

When applying electrode pads for TENS therapy, it's essential to avoid certain areas for safe and effective use. These include:

  • Spinal cord
  • The front or side of your neck
  • Temples
  • Mouth 
  • Eyes
  • Heart, chest
  • Genitals
  • Irritated, delicate, or broken skin
  • Varicose veins
  • Numb areas of your body
