What Are Maternity TENS Electrodes, and Why Are They Different?

The electrodes are the part of a TENS machine that actually touches you, so their size, material and quality make a real difference to how comfortable and effective your labour TENS is. Here is what maternity electrodes are and why they are not the same as a generic pad.

What maternity electrodes do

A labour TENS machine sends small, adjustable electrical pulses through the skin to help manage pain. Those pulses travel through adhesive pads called electrodes. For labour, the electrodes are placed on your lower back so the pulses reach the nerves that carry contraction pain. Good electrodes deliver that current evenly and stay put through hours of movement.

Why maternity electrodes are larger

Maternity electrodes are deliberately big, 40 x 100mm rectangles, larger than the small square pads used for general muscle or joint TENS. The larger surface area covers the broad bands of nerves on either side of the spine that carry labour pain, spreads the sensation comfortably, and gives reliable contact during a long labour. A small physio pad simply does not cover the right area for birth.

What the Elle TENS electrodes are made of

The Elle TENS maternity electrodes are manufactured by Body Clock, the company that developed the world's first obstetric TENS. They are:

• Medical-grade and hypoallergenic, chosen to be kind to skin during the hormonal changes of late pregnancy and labour.
• Biocompatibility tested and SGS certified, so the material that sits against your skin has been independently assessed.
• Included on the ARTG (225921) as part of the Elle TENS system.
• Single-use and hygienic, supplied fresh so adhesion and conductivity are reliable.

Skin can be more reactive in pregnancy, so a tested, hypoallergenic adhesive matters. Research on TENS use notes that skin reactions are linked to electrode material and quality, which is exactly why the maternity electrodes use a medical-grade hypoallergenic gel rather than a generic one.

Genuine electrodes, every time

Because the electrodes are so central to a comfortable labour, Elle TENS supplies genuine maternity electrodes with every machine and replaces them fresh for each hire. You can buy additional maternity TENS electrodes any time. To understand why matching electrodes matter, see can you use any electrodes with your Elle TENS machine, and for getting the most from them, read how to care for, clean and replace your TENS electrodes.

Frequently asked questions

What size are maternity TENS electrodes?
The Elle TENS maternity electrodes are 40 x 100mm rectangles, larger than standard physio pads so they cover the nerves that carry labour pain.

Are maternity electrodes different from normal TENS pads?
Yes. They are larger and shaped for labour placement on the lower back, and they use a medical-grade hypoallergenic adhesive suited to pregnancy skin.

Are Elle TENS electrodes safe for sensitive skin?
They are medical-grade, hypoallergenic and biocompatibility tested. If you have very reactive skin or a known adhesive allergy, mention it to your midwife.

Are the electrodes reusable?
Maternity electrodes are designed for single-person use. Fresh adhesion and clean contact give the best comfort and performance, which is why Elle TENS replaces them for every hire.

Where do the electrodes go for labour?
On the lower back, either side of the spine, positioned over the areas that carry contraction pain. Your machine guide shows the exact placement.
