How the TENS Pain Control Units Work
Pain is the body's warning system. It is a
way of letting an individual know that something is wrong.
Transcutaneous Electrical Nerve Stimulations (TENS) is a safe
non-invasive drug-free method of pain management. It relieves pain by
sending small electrical impulses through electrodes placed on the
skin to underlying nerve fibers. TENS is believed to work by two
different mechanisms. First, electrical stimulation of the nerve
fibers can block a pain signal from being carried to the brain. If
the signal is blocked, pain is not perceived. Secondly, the body has
its own mechanism for suppressing pain. It does this by releasing
natural chemicals called endorphins in the brain which act as
analgesics. TENS may activate this mechanism. By effectively managing
pain without drugs, TENS allows many people with chronic pain
conditions to resume daily activity.
You can not strain or sprain your muscles by overworking them with
your electronic muscle stimulator system because the feeling is more
like a pleasant tingling sensation than a shock or jolt.
However, the following should not use electronic muscle stimulators
Just as with starting any new exercise
program, if in doubt, consult your physician.
