Electronic stimulators, also called transcutaneous electrical nerve stimulation (TENS) units, can help relieve pain due to illness or injury. Electronic stimulator therapy often works best when combined with other pain relief methods, such as medications and therapy.

Equipment

Electronic stimulators are small machines that patients can take with them. Most electronic stimulators are battery operated.

How to Use

Electronic stimulators have sticky electrodes that patients can attach to the skin in areas where they feel pain. The machine sends small electrical impulses through the electrodes to the skin.

Body's Response

The electrical impulses help the brain release endorphins, which act as natural painkillers. The stimulated nerves below the skin can also block pain signals from reaching the brain so that the patient does not perceive the pain.

How to Purchase

Anyone can purchase an electronic stimulator from a medical supply store. Patients with a prescription may be able to recover some or all of the cost of the unit from their insurance companies. Some medical equipment companies offer rental programs for electronic stimulators as well.

Warning

Patients with pacemakers and pregnant women should not use electronic stimulators unless directed to do so by their doctors. Patients should always use the settings advised by their doctors or physical therapists to prevent nerve damage from overstimulation.
