1. SAFETY INFORMATION
1.1 General
InTENSityTM Twin Stim~ Ill is a portable electrotherapy device featuring
two therapeutic modes: Transcutaneous Electrical Nerve Stimulator
(TENS) and Electrical Muscle Stimulation (EMS), which are used
for pain relief and electrical muscle stimulation. The stimulator
sends gentle electrical current to underlying nerves and muscle
group via electrodes applied on the skin. The parameters of device
are controlled by the buttons on the front panel. The intensity level
is adjustable according to the needs of patients.
1.2 Medical background
EXPLANATION OF PAIN
Pain is a warning system and the body’s method of telling us that
something is wrong. Pain is important; without it abnormal conditions
may go undetected, causing damage or injury to vital parts of our
bodies. Even though pain is a necessary warning signal of trauma or
malfunction in the body, nature may have gone too far in its design.
Aside from its value in diagnosis, long-lasting persistent pain serves
no useful purpose. Pain does not begin until the coded message
travels to the brain where it is decoded, analyzed, and then reacted to.
The pain message travels from the injured area along the small
nerves leading to the spinal cord. Here the message is switched to
different nerves that travel up the spinal cord to the brain. The pain
message is then interpreted, referred back and the pain is felt.
EXPLANATION OF TENS
Transcutaneous Electrical Nerve Stimulation (TENS) is a non
invasive, drug free method of controlling pain. TENS uses tiny
electrical impulses sent through the skin to nerves to modify your
pain perception. TENS does not cure any physiological problem;
it only helps control the pain. TENS does not work for everyone;
