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 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 analyses the pain message, refers it back and the pain is felt.
What is TENS? Transcutaneous Electrical Nerve Stimulation (TENS) uses a small battery operated unit to provide a non-invasive, drug free 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 Physiotherapists and Doctors 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. These larger nerve fibres transmit less unpleasant sensations such as touch or warmth, assisting us to form an impression of our environment. Stimulating the larger nerve fibres using TENS may have the effect of inhibiting the transmission of pain along the smaller nerve fibres to the spinal cord [known as the ‘Pain Gate Theory’].

NeuroTrac™ Rehab Operation Manual
What is STIM? Neuromuscular Stimulation has been used for many years to stimulate muscle and nerve fibres to treat a number of muscle and nerve related conditions. Over the last 30 years numerous clinical trials and papers have been written. The NeuroTrac™ Rehab is a dual channel device combining several treatment programmes into one unit. Neuromuscular Stimulation is increasingly understood by Therapists and Doctors. There is a better understanding of the mechanisms which exist between nerves and muscles that makes it possible to stimulate the neuromuscular system with precise electrical signals. The NeuroTrac™ Rehab offers precision giving full control of Pulse Widths, Rates, Ramp up times, Work / Rest cycles as well as alternating or synchronous application if two channels are being applied. Customer Care We welcome constructive comments regarding our equipment particularly those that might help us to improve existing features, add new ones or develop new products for the future.

Contra Indications & Precautions Before using this equipment you must first seek the advice of your Physiotherapist or Doctor. Read this operating manual before using the unit TENS and STIM should not be used: * * * * * * *
* * *
* *
By patients fitted with a demand style cardiac pacemakers unless so advised by their Doctor During pregnancy [unless medically advised] By patients with undiagnosed pain conditions With patients who have diminished mental capacity or physical competence who cannot handle the device properly On anaesthetised or desensitised skin When driving a vehicle or operating potentially dangerous equipment Do not place electrodes: * Over carotid sinus nerves * Over larynx or trachea * Inside mouth * Over the area of the heart unless so advised by your Doctor * On your facial area unless under strict guidance from a qualified Clinician The patient should use the unit only as prescribed Do not immerse the unit in water or any other liquid If you experience skin irritation this may be due to over-stimulation. In this case leave the skin to heal and use the unit only for the periods prescribed. Turning the current up too high can cause skin irritation. In this case allow the skin to heal and use the unit at a lower intensity. Some people experience an allergic reaction to the adhesive coating on the surface of the electrode. If this happens use a different make of electrode or change the electrode. If it continues try reducing the pulse width. If the problem still persists try moving the electrode position each day by just the width of the electrode, making sure the electrode positioning is still over the dermatome Keep unit out of reach of children If in doubt about the use of the NeuroTrac™ Rehab unit, call your Doctor, Therapist, Clinician or Verity Medical Ltd. for advice
