What is TENS?

Transcutaneous Electrical Nerve Stimulation (TENS) is a non-invasive, drug-free method of relieving chronic pain. A TENS device sends tiny electrical impulses through the skin to small nerves. These tiny impulses help trigger a different message than the original pain message being sent to the brain, eliminating the feeling of pain.

Your Theratech device is equipped to send a wide range of pulse widths and durations. Each setting is designed to have a varied effect on the small nerves near or around the pain producing area. These electrical pulses can result in a soft tapping sensation or in large muscle contractions. Naturally, different settings will have different results for different users, and it is recommended that all users experiment to find the most effective setting. You should consult a physician who is knowledgeable about TENS in order to get the most from your new TENS device.
