Safety Informatio; Medical Background - intensity IF COMBO DI4738 Instruction Manual

1.1 General
InTENSity IF Combo stimulator is a portable electrotherapy device
TM
featuring two therapeutic modes: Transcutaneous Electrical Nerve
Stimulation (TENS) and Interferential (IF), which are used for pain
relief. 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 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;
however, in most patients it is effective in reducing or eliminating the
pain, allowing for a return to normal activity.
HOW TENS WORKS
There is nothing "magic" about Transcutaneous Electrical Nerve
Stimulation (TENS). TENS is intended to be used to relieve pain.
The TENS unit sends comfortable impulses through the skin that
stimulate the nerve (or nerves) in the treatment area. In many cases,
