TENS, which stands for Transcutaneous Electrical Nerve Stimulation, is used to effectively treat and eliminate pain conditions. TENS machines work by transmitting electrical pulses across the surface of the skin and along nerve strands to block pain signals from reaching the brain. They also help stimulate the body to produce endorphins, which are natural painkillers.
TENS unit pads are placed strategically around the painful area; they can be placed vertically or horizontally. They should ideally be placed one inch apart and should not touch each other, in order to maximize the effectiveness of the electrodes.
The strength of the electrical current given to the electrode and how long each pulse width is can be personalized depending on what pulsation effects the user wants. The frequency of the current is measured in megahertz.
