Transcutaneous Electrical Nerve Stimulation (TENS)

What is TENS?

TENS stands for Transcutaneous Electrical Nerve Stimulation. TENS units send electrical pulses through the skin to the nerves to control pain. Unlike drugs, TENS does not have any major side effects.

How does TENS help pain?

  • The TENS blocks pain signals and confuses your brain so that you are not aware of the pain. 

  • The body releases natural pain killers, called endorphins. These chemicals block the awareness of pain. This is how the TENS may provide pain relief, even after it is removed. You may wear a TENS unit as many hours as you need for pain control.

How to Start a Session

  1. Connect the lead wire(s) to the patches and the device. NOTE: Make sure the device is turned off.

  2. Wash and dry the skin areas where you will be putting the patches. 

  3. Apply the patches to your skin.

  4. On the device, press the on/off button.

  5. Start in the SMP mode.

  6. Use the Ch1 and Ch 2 buttons to set the strength for each channel. Increase the strength until you feel a strong but not painful feeling. It should not cause your muscles to contract.

How to Change a Session

  • If SMP mode is not working well, there are other program options. 

  • You can change options by pressing the mode button or any of the five Quick Select Program buttons. 

  • For safety, the device will lock. Press the down button to unlock.

How to End a Session

  1. On the device, press the on/off button to shut the device off.

  2. Disconnect the wire(s) from the patches.

  3. Remove the patches from your skin. Place back on the plastic backings between uses. If they are too dry, apply a drop of water to the patch.

  4. Use skin cream or lotion to your skin after taking off the patches.
