The Obi TENS is simple, versatile and perfect for those painful moments during labour. It is one of the most effective, portable, affordable TENS machines available today. The Obi TENS is an ultra simple yet powerful obstetric TENS unit perfect for drug-free pain relief during labour. It has 2 pre-set modes one for use during contractions, the other for use between contractions.


The sooner you start using TENS in labor, the better it tends to work. If you hire a doula or midwife, they may have a TENS, but you may want to start using it before they arrive to support you, so renting one for yourself is a great idea.

Hospitals do not have TENS available in Labor & Delivery.


A TENS unit works by sending mild electrical impulses to sticky pads on your lower back. TENS works as the electrical pulses stimulate nerves that run to the spinal cord and block the transmission of pain. This creates a tingling feeling. You can control the strength of the current yourself. It is safe for most laboring people and their babies. TENS also work by providing a distraction and giving you a sense of control, both of which may lessen the anxiety that can delay the progress of labor.

TENS is safe for most laboring people and their babies. It can be used while baby's heart rate is being monitored without disruption. TENS may not be used in water.
