What is Pain?

Pain warns our body of injury. This warning system is intended to prevent additional damage. The sensation of pain is important, because without it, vital parts of our bodies might be injured without knowledge. However, long lasting, persistent pain, often called chronic pain once diagnosed serves no apparent purpose. TENS is developed to help relieve certain types of chronic and acute pain.

How Does TENS Work?

TENS or Transcutaneous Electric Nerve Stimulation refers to the transmission of small electrical pulses through the skin to underlaying peripheral nerves. The theory of TENS suggest two different modes of operation.

Conventional (high frequency) TENS is based on the theory that continuous mild electrical activity may block the pain signals traveling to the brain. If the pain signals does not go to the brain the pain is not “felt”. The second way TENS thought to work is stimulating the body's natural pain control mechanism “low frequency” or short bursts of electrical activity may cause the body to release pain-relieve substances, called endorphins. Research has shown that continued use of TENS will actually prevent recurrent spasm, thus expediting the healing process.
