How Maternity TENS works
A maternity TENS machine consists of a battery-powered, hand-held controller connected by fine leads to four flat pads. The pads are covered in a firm gel that helps them stick to your back. Maternity TENS works in the same way as general TENS by: preventing pain signals from reaching your brain and stimulating the body to release endorphins. Additionally, it helps mum-to-be to feel in control of the labour and be less anxious and it also offers a distraction from the contractions.
The machine sends small, safe pulses of electrical current via the leads to the pads on your skin. The pulses pass through your skin and into the muscles and tissues. This gives a gentle tingling or buzzing sensation, which may be stronger or weaker, depending on the setting level. A TENS machine has buttons that you can use to control the frequency and strength of the pulses. There is also a boost button when you want maximum output from the machine. This may help you to get through each contraction.
