It is common knowledge that labor can be a very painful process for women, since, during this process, the contraction of the muscles and the pressure on the cervix generate a sensation of pain that can be described as an intense cramping that affects the abdomen, groin and lower back.
Because of this, methods have been developed to prevent women in labor from going through such high levels of pain. Transcutaneous Electrical Nerve Stimulation (TENS) and Electro Muscle Stimulation (EMS) electrotherapy are used to counteract labor pain, thanks to their history of effectiveness in treating various types of ailments. Below, we will teach you all the points to take into consideration when using a TENS or EMS electro stimulator, and how to apply them to minimize labor pain.
How to use a TENS device to relieve pain during labor?
By correctly applying electrotherapy treatment during the pregnancy process, it is possible to see a certain amount of benefits for both the mother and the baby, although it is necessary to take into consideration criteria such as the intensity necessary for the application of the electric current to be effective.
Benefits
The advantages of the application of TENS to the mother during labor stem from its overall effectiveness in relieving pain and its non-chemical and non-invasive nature, providing control over the pain caused by the process.
Among the main benefits of the use of TENS during labor, we can highlight the following:
- Does not require ingestion or injection of drugs or other chemicals
- It is possible to control the intensity of the shock to suit the sensation at the moment
- Does not limit mobility in any way
- It can be combined with other methods if TENS does not provide sufficient relief
- Completely harmless for both mother and baby
- Can be applied from the first contractions
How often to use?
The non-pharmacological nature of TENS therapy makes it one of the safest options for pain relief during labor, although it is necessary to take into consideration the use of a medium - high intensity, and a wide frequency between shocks for greater effectiveness.
With this said, the optimal range of intensity for TENS application is between 80 Hz and 100 Hz. This intensity is modifiable as the labor process progresses, maintaining a constant pulse frequency of 350 microseconds.

Electrodes for childbirth
In such a delicate process as labor, it is necessary to verify the positioning of the electrodes to be sure that they will act as expected, exerting their effect on the correct nerve branches.
First contractions
The ideal time to apply TENS units is at the beginning of the labor process, at the onset of the first contractions, since this is the stage in which its effect has proven to be most effective in most cases.
The positioning of the electrodes should be aligned with the areas where the nerves of the uterus and uterine canal join the spinal cord. While these are positions that may vary depending on the individual patient's sensation, the generally most effective locations are as follows:
- On both sides of the T10 vertebra at the level of the
- At the level of the S3 vertebra, on each side of the spinal column
With epidural
The application of electrical currents from TENS units allows an extra boost to be added to the effect of the epidural by increasing the patient's sense of relief, although in general the margin for improvement is not too great, since the epidural alone provides fairly complete relief.
The positioning of the electrodes with or without the use of the epidural remains constant, since the regions next to the spinal cord, at the level of the T10 and S3 vertebrae house the nerves that receive the greatest pressure during the delivery process.

Can electrotherapy be used during labor and delivery?
There is very little research regarding the effectiveness of Transcutaneous Electrical Nerve Stimulation for labor pain, however, there have been randomized trials in patients that suggest its use is favorable.
Studies conducted in 2011, 2013 and 2016 have shown that the use of TENS electrotherapy during labor can cause a considerable reduction in pain sensation, to the point where it can replace or at the very least postpone the use of analgesic medications such as epidurals.
Differences between TENS and EMS: Which is better for pain relief during labor?
While electrotherapy has proven to be effective in the treatment of ailments of various origins, it is necessary to be especially careful when dealing with a process as delicate as labor, so it is necessary to be fully aware of the effects of both TENS and EMS therapy.
Transcutaneous Electrical Nerve Stimulation (TENS) therapy is a physiotherapeutic method aimed at treating ailments caused by disorders and traumas of varying severity.
During childbirth, it works through the application of electric shocks of variable intensity (1 Hz - 250 Hz) that directly affect the sensory endings of the sciatic nerve and the L5 nerve root, caused by the contraction of the transverse, oblique and rectus abdominis muscles and the deep musculature of the pelvic floor, mitigating the sensation of pain during the process of childbirth.
Electro Muscular Stimulation (EMS) works mainly as a physical conditioning method, focusing its functions on the stimulation of muscle groups by means of medium to high intensity electrical discharges designed to improve the strength, resistance and elasticity of muscle tissue by means of contractions that vary in frequency and intensity.
To date, there is very little evidence to support the use of EMS therapy to counteract the pain caused by labor, so the safest and most proven effective option is TENS therapy, thanks to its direct interaction with the nerves responsible for the sensation of pain in the abdominal, lumbar and pelvic area, and its ability to promote the release of endorphins, providing a natural reduction in the sensation of pain.
Can TENS be used with epidural?
Epidurals are the most widely used technique to minimize the pain of childbirth, and in most cases do not adversely affect the mother or the fetus. For this reason, applying Transcutaneous Electrical Nerve Stimulation in conjunction with the epidural can help with pain relief during labor.
In addition, TENS therapy is presented as a solid alternative to reduce the mother's discomfort during labor when an epidural is not a viable option. For example, when the mother suffers from conditions such as peripheral neuropathy, certain heart conditions, epilepsy or simply the patient's desire not to apply the technique.
Can TENS current affect the baby?
The use of any type of electrotherapy is widely contraindicated during the first 12 weeks of gestation, due to the fact that during this stage the fetus is highly sensitive to any alteration and may suffer damages derived from the electric current. However, once this period has passed, the use of TENS therapy is completely safe.
The use of TENS during childbirth is recommended because it can contribute to reduce the sensation of pain in the mother without the use of chemicals, so it is possible to avoid future breastfeeding problems, in addition to not presenting any side effects for the mother or the baby.
