perception. TENS does not cure any physiological
problem. It only helps control the pain. TENS does
not work for everyone. However, in most patients,
it is effective in reducing or eliminating the pain,
allowing for a return to normal activity.
How does TENS work?
Scientific theory suggests that electrical stimulation
therapy may work in several ways:
n The gentle electrical pulses move through the
skin to nerves nearby the sources of pain,
shutting out the pain message from ever
reaching the brain.
n The gentle electrical pulses increase the
production of endorphins, the body’s natural
pain killer.
INTRODUCTION

The pain reliever ACRL-1000 is a TENS stimulator.
What is TENS?
TENS stands for Transcutaneous Electrical Nerve
Stimulation. It is a noninvasive, drug-free method of
controlling pain. TENS uses tiny electrical impulses
sent through the skin to the nerves to modify pain

5
