How the NPI Therapy device works

The Class 1 medical device is intended to produce a small magnetic field which passes through a specific area hindered by pain. The quadrapolar magnetic device works to provide comfort and therapeutic relief from chronic pain that can be experienced in the back, neck, shoulder and knee areas. 

The NPI devices are typically applied directly onto the skin with a hypoallergenic adhesive. They are a realistic and affordable form of pain relief that avoids the use of prescription medication.

NPI devices are comfortable to wear, extremely powerful and ideal in ensuring you can continue to live your life normally, without the difficulties and stress created by chronic pain.

“From this study it has emerged that inserting a quadruple magnet in a plaster cast in hand and wrist fractures results in the formation of bone callus in an average time that is 35% inferior to ‘standard time’.”

Markov 2009

“A number of clinical studies, in vito animal experiments and in vitro cellular and membrane research, all suggest that magnetic and electromagnetic field stimulation can accelerate the healing processes.

Magnetic Fields (MF) have been proven to be clinically safe, and is well accepted that MF provide a practical, non-invasive method for inducing cell and tissue modifications which can correct selected pathological states.

The most effective clinical applications of these fields over the past 25 years relate to bone unification, pain reduction and soft tissue oedema. The treatment success rate for these patients approaches 80%, with virtually no reported complications after nearly three decades of use.”

Harvard Medical School of Study 2004

“There is scientific evidence that suggests static magnetic therapy can affect biological systems, thereby potentially affecting pain due to osteoarthritis. 

In-vito experimental evidence suggests that static magnetic fields can do the following: decrease the firing rate of certain neurons, particularly C-type chronic pain neurons; change the rate of enzyme-mediated reactions which may play a role in inflammatory cascades and free radical generation; modulate intracellular signalling by affecting the functioning of calcium channels in blood flow.”
