Neuromuscular Stimulation has been used for many years to stimulate muscle
and nerve bres 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® Sports is one of a new breed of modern Neuromuscular
Stimulators which Verity Medical have developed with the Therapist and
Patient in mind. Our principle aim is to design products that have high levels of
functional use, are sensibly priced, compact and user friendly.
The NeuroTrac® Sports is a dual channel device combining several treat-
ment 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 Sports
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.

* Self-Adhesive reusable long-term electrodes (if looked after) have a
typical life span of 4/6 weeks. We recommend cleaning the skin with
an alcohol-based wipe before placing the electrodes. The wipe should
not contain fat as any grease will degrade the electrode stickiness. After
use, place the electrodes back onto the plastic lm and in the zip-tag
plastic pouch. Store in a cool environment which is not too dry.
Skin Electrode Types Available:
Electrode Types & Tips
A Few Good Tips [Self- Adhesive Electrodes]
* If you nd the electrodes will not stick due to oily skin, cleanse the
skin with soap and water, then rinse and dry the area around the
electrode site. If this does not work, try cleansing the skin with a
swab impregnated with alcohol.
* Clip away hairy skin using a scissors; don’t use a razor to remove
the hairs!
* The electrodes conductive material is water- based. If it becomes
saturated (e.g. from perspiration), it will lose its adhesive qualities.
After use leave the electrodes face up overnight to dry out (replace
on plastic lm in the morning).
At some point the electrodes will become dry. Moisten the adhesive
surface with a few drops of water, and apply onto the plastic lm
overnight. This procedure will give you a few more days of electrode
life.

Applications
Self-Adhesive Electrodes:
* Check the short connectors have not become separated from the
electrodes
* Replace electrodes onto plastic lm after use. If they drop onto the
oor debris will adhere to conductive gel rendering the electrodes
ineffective
Electrode life can be considerably reduced by:
* The type and condition of the skin
* Deep seated moisturisers or make-up
For the Best Results:
* Before each use cleanse the skin
* After each use stick the pads on the shiny insert card and store in a
cool and dry place, such as the fridge. (not freezer).
