TENS/EMS Instructions

Transcutaneous electrical nerve stimulation (TENS) is a method of pain relief involving the use of a mild electrical current. A TENS machine is a small, battery-operated device that has leads connected to sticky pads called electrodes. You attach the pads directly to your skin. When the machine is switched on, small electrical impulses are delivered to the affected area of your body, which you feel as a tingling sensation. The electrical impulses can reduce the pain signals going to the spinal cord and brain, which may help relieve pain and relax muscles. They may also stimulate the production of endorphins, which are the body's natural painkillers. What TENS is used for TENS may be able to help reduce pain and muscle spasms caused by a wide range of conditions including: arthritis period pain pelvic pain caused by endometriosis knee pain neck pain back pain sports injuries How to use TENS The information below is a general guide on how to use a TENS machine. You should always follow the manufacturer's specific instructions. TENS machines are small and lightweight, so you can use them while you're working or on the move. You can put it in your pocket, clip it to your belt or hold it in your hand. You can use TENS throughout the day for as long as you like, although it shouldn't be used while you're driving, operating machinery, or in the bath or shower.  Positioning the pads Make sure the machine is switched off before you attach the pads to your skin. Position the pads either side of the painful area, at least 2.5cm (1 inch) apart.

You'll feel a slight tingling sensation pass through your skin. The machine has a dial that allows you to control the strength of the electrical impulses. Start on a low setting and gradually increase it until the sensation feels strong but comfortable. If the tingling sensation starts to feel painful or uncomfortable, reduce it slightly. Switch the TENS machine off after you've finished using it and remove the electrodes from your skin. Are there any risks of side effects?
