Electric Stimulation

A four-lead TENS unit.
Electrical stimulation is also known as Transcutaneous Electrical Nerve Stimulation (TENS). TENS delivers a painless electrical current through the patient's skin to specific nerves. The current produces mild heat that works to relieve stiffness and pain and helps to improve range of motion (mobility). This treatment is a non-invasive, safe nerve stimulation intended to reduce pain, both acute and chronic. More information available at: Wikipedia.
