Key Series Technology

The technology used in the Key Devices relies on the body’s mechanism of adaptation,physiokey_keyhealthtechnology ensuring dynamic equilibrium or, homeostasis. Regulation of the body’s vital functions is achieved through close connection and interaction of the nervous and endocrine systems. The effects of these systems results in the release of biologically active chemical modulators called neuromediators. Examples of these are acetylcholine, adrenaline and nor-adrenaline. Amino acids are another type of chemical modulator. These are important in activation of the thickly myelinated A- and B-neural fibres. Examples of this modulator include glutamine and asparagine. The largest group of chemical modulators are the neuromediators and include endorphins (the ‘feel good’ chemical modulator), enkephalins and bradykinin.

Central to massage therapy with the Key devices, are the body’s chemical modulators, neuropeptides. These are the main modulators of neural activity of the thin non-myelinated, ‘difficult-to-excite’ C-fibres. These neuropeptide-producing nerve fibres make up more than 70% of the body’s neural tracts. C-fibre’s specific properties enable the production of a powerful analgesic effect, which is brought about by the release of neuropeptides, once the C-fibre is activated.

The main goal of Key device massage therapy is fast and sustained pain relief by activating a maximum number of C-fibres to induce the secretion of a sufficient amount of neuropeptides.

The bio-feedback controlled massage impulse of the Key devices means that the device communicates actively with the processes that are happening in the body by monitoring the skin’s impedance and then adjusts the massage impulse it is sending out in accordance with the changes in the skin’s impedance.

The characteristics of the bio-feedback controlled massage impulses are such that the probability of excitation of the thin neuropeptide-secreting C-fibres is higher than conventional methods of electrotherapy ₉ ₁₀ ₁₁.

Clinical experience with the technology has further indicated that the optimal therapeutic effect is achieved when there is a maximal variability of the impulse parameters during treatment ₁₂ ₁₃ ₁₄.
The optimum therapeutic results are always dependent upon the patient’s body’s response and therefore individual to each client. As the device monitors and evaluates treatment results it independently delivers the correct massage impulse without the possibility of overdosing and hence very few side effects.

I do have re-occurring injuries. I had the opportunity to be treated by Chris Mortensen – the main benefit for me was being able to stretch further – improve my function mainly of my hips.

I have been using my device on my ruptured Patella tendon. I have found the treatment to be highly and immediately effective. This treatment has really improved my recovery.

Your service, ethics, and prompt attention and answers to the many questions have been greatly appreciated.As you know, I LOVE, LOVE, LOVE, my Sanakey!   I have become quite possessive about it and told the kids they can come over and use it here, that way when WE need it, it’s here!

Peter and the team at Key Health Technology are knowledgeable and highly effective in supporting their practitioners and clients who purchase any of the Key devices. You will never be left alone to fend for yourself and can always ask questions.
