Transcutaneous electrical nerve stimulation (TENS) is a peripheral, non-invasive technique which involves the passage of electrical currents across intact skin to stimulate intact nerves causing sensory stimulation and, in some cases, non-functional muscle twitches. It’s used for acute and chronic pain. In fact, electricity has been used for pain relief since the Egyptians used electrogenic fish applied to painful body parts.
Which conditions can be treated with TENS?
TENS should be used as part of a multimodal pain management program, thereby reducing the amount of medication required by a patient.
