NeuroTrac™ IFC Rehab Operation Manual

2. Introduction to the product

NeuroTrac™ IFC Rehab is a pain control and muscle stimulator device. It combines
Interferential stimulator (IFC), Transcutaneous Electrical Nerve Stimulator (TENS)
and Neuromuscular Electrical stimulator (NMS) in one unit. The device consists of
two independent circuits, one for IFC, another for TENS/NMS stimulation. There
are two output Channels for the NMS and another two for the IFC allowing it
to operate 2 pairs of electrodes for each side of the device. They are all isolated
from each other and work independently with no exchange of current between
any of the channels.
IFC Rehab has 11 built� in preset programmes for Interferential stimulation ,
12 for TENS stimulation and 15 for NMS stimulation. Additionally there are
custom programmes ( 2 for IFC, 2 for NMS and 1 for TENS) which allow to vary
programme parameters.
Each of two parts of the device ( IFC or TENS/NMS) can be locked separately by
Physician to prevent patient from changing programme parameters and to allow
verification of the training by collecting "total time used" and average output
amplitude statistic.

2.1. What is Pain

When we feel pain it is the body's process of informing us that something is
wrong. To feel pain is important, without this feeling abnormal conditions may
go undetected, creating damage or injury to critical parts of the body.
Although pain is essential in warning our body of trauma or malfunction, nature
may have gone too far in its design. Continued long�term chronic pain has no
useful value apart from its importance in diagnosis. Pain only begins when a
coded signal travels to the brain where it is decoded, and analysed. The pain
message travels from the injured area of the body along small diameter nerves
leading to the spinal cord. At this point the message is switched to a different
kind of nerve that travels up the spinal cord to the brain area. The brain then
analysis the pain message, refers it back and the pain is felt.

2.2. What is TENS

Transcutaneous Electrical Nerve Stimulation (TENS) is a non�invasive method of
controlling acute and principally long term intractable pain. It can also be used
as an adjunctive treatment in the management of post surgical traumatic pain
problems. In TENS mild electrical impulses are transmuted through the skin via
surface electrodes to modify the body's pain perception. TENS does not cure
problematic physiological conditions; it only helps to control the pain perception.
TENS will not work for every user. However Physical Therapists and Physicians
throughout the world prescribe TENS extensively and it is generally seen to work
for the majority of users. There are millions of small nerve fibres throughout the
body and it only requires a few impulses to produce chronic pain. In addition to
small fibres, which allow the sensation of pain to be felt, the body is also made
up of larger diameter nerve fibres.
