Labor TENS Unit

Why Use a TENS Unit for Labor?

What Is a Maternity TENS Unit & How Does It Work?

A Maternity TENS (Transcutaneous Electrical Nerve Stimulation) unit is a portable, drug-free device designed to ease labor contraction discomfort. 

Using four adhesive pads placed on your back, it delivers mild electrical pulses that trigger the gate control theory of pain management—blocking pain signals from reaching your brain while prompting your body to release natural, pain-relieving endorphins. (Want to learn more about the benefits of labor TENS units?

The UK vs. US Advantage

Unlike standard over-the-counter TENS machines in the U.S.—which are designed for chronic pain and require manual dial adjustments—our specialized UK-imported maternity units feature:

• Dual-Channel Control: Independently target both your upper and lower back for customized coverage.
• Handheld Boost Button: Instantly ramp up intensity at the peak of a surge and quickly dial it back down as the wave passes, keeping you in complete control of your comfort throughout labor.

Flexible Comfort: Comparing Your Labor Options

Choosing medical pain interventions during labor, such as an epidural, can restrict your mobility if you desire an active birth. Other hospital options like nitrous oxide (laughing gas) are rarely offered, while medications like Nubain, Fentanyl, or Demerol can make you and your baby drowsy.

Using TENS for pain relief gives you complete control over your comfort without medication or movement restrictions.

Using TENS Alongside Other Options or Epidurals

We view TENS as one versatile tool in your comfort toolbox. Many of our clients use a TENS unit during early and active labor at home to navigate contractions comfortably for hours—allowing them to delay hospital admission or an epidural until they are further dilated.

If you decide to get an epidural later or enter a birth pool, you can simply turn off the device and remove the pads. All other medical and non-medical comfort measures to relieve pain remain completely open to you.

The TENS Unit is Easy to Use

Simple Steps to Use Your TENS Unit

Using the device is straightforward—follow these quick steps (or watch our demonstration video below):

1. Prepare the Device: Turn off the machine before placing the pads on your back.
2. Apply the Electrodes: Place two pads from the first dual-channel output on each side of your spinal cord at bra-strap height. Place the other two pads lower down, at about the level of the dimples on your lower back (just above your bottom).
3. Power On: Switch on your maternity TENS unit, starting at the lowest setting.
4. Use the Boost Function: Press the boost button at the peak of each contraction to maximize TENS for pain relief. Remember to turn off the boost feature once the contraction ends.
5. Maintain Mobility: Moving around during labor helps you feel in control and maximizes the effectiveness of TENS machines.
6. Pad Care: If the electrode pads lose stickiness during a long labor, add a few drops of water to the gel side before reapplying them.
7. Stay in Control: If the pads stop helping after a while, simply take them off. You remain in control of your labor.

Safety Precautions: When NOT to Use a TENS Unit

TENS units should not be used:

• Before 37 weeks of pregnancy (unless explicitly instructed by your healthcare provider)
• In water (such as birth tubs, showers, or baths)
• By individuals with cardiac pacemakers, severe heart conditions, or epilepsy

Always consult your midwife or OB-GYN before adding TENS to your official birth plan.
