Sanakey FAQ’s

Who can benefit from using the sanakey?

The sanakey personal pain relief device is a 100% drug-free non-invasive pain relief treatment that can be used by people of all ages.

How often do I need to use sanakey before I see a difference to my pain?

This will depend on many factors.

If your injury is recent then you may achieve fast pain relief with only one or two applications of the sanakey. Other injuries that are chronic may take longer.

If you suffer from chronic pain then you may need more sessions (even every day) to get significant long lasting results.

I just want pain relief. Do I really need to watch the training videos?

We appreciate that you may be in constant pain and just want the quickest solution, so you can watch a quick walk through video here. Within minutes of powering up your sanakey we are confident by using our simple three-step protocol you can ease your pain.


The training videos are important. Aside from being available 24/7, always, they will give you step by step instructions how to use the sanakey effectively for various painful complaints.


The rest of the support we give is real and will make a big difference. If the answer to your problem or difficulty is not in the training material via the Practical User Manual supplied with the sanakey and via the videos on, then we are always available by phone or through our contact page. We understand pain and will respond as fast as we can.

I'm not good with technology! Will I be able to use the sanakey correctly?

The sanakey is incredibly simple to use.

Once you understand the basic functions and become comfortable with the program settings you will be pleasantly surprised how easy it is to use!

We are always on hand to help via telephone, email, our Facebook page, and of course if you are near the The Clinic we are more than happy to give you a run-through session!

How does using the sanakey differ to conventional TENS therapy?

Using the sanakey is a quantum leap in technology over conventional TENS Therapy.

In conventional TENS therapy, for example, the pain subsides usually only while the TENS unit is activated. Using the sanakey, pain relief may extend beyond the actual treatment, often weeks beyond. That’s because with the use of TENS devices, the body adapts itself to the electrical signal and eventually just ignores it. The net result? The pain returns.

This is one of the major distinguishing factors in Non-Invasive Interactive Neurostimulation therapy. The device sends out a signal and then waits for it to return from the body. The device then reads the returning signal and adjusts its own subsequent signal. Because of this feedback mechanism, each new signal differs from the previous one, thus overcoming the adaptiveness of the body to a single, continuous electrical signal as in TENS.

Using the sanakey may also influence local blood flow, especially in regulating micro-circulation. That’s important in the treatment of sports injuries, as blood brings the building blocks for repair and removes dead tissue and waste products. But one of the biggest factors in the effectiveness of using the sanakey is its ability to induce the release of neuropeptides. While the sanakey also induces the body to release natural opium-like painkillers called endorphins (similar to the action of TENS), it is the release of neuropeptides that enables sanakey to quickly help heal injuries of all types.


sanakey – dynamic therapy. The device is moved over the skin in order to specifically find optimal treatment areas.

TENS – passive therapy. Treatment is non-specific. Stimulation is used to block the sensation of pain with electrodes adhered to the skin.

sanakey – specificity of treatment. The unique waveform uses biofeedback to detect areas on the skin that are neurologically related to areas of injured tissue.

TENS – non-specific treatment. Electrodes are placed on or around the area on the skin that is painful. There is no biofeedback so no detection of injured tissue.

sanakey – unique waveform. Pulsed, damped, sinusoidal and skin-impedance sensitive. High amplitude and very short pulse width of the waveform prevents accommodation. No two waveforms are the same.

TENS – waveforms typically square, spiked or sine, mono-phasic or bi-phasic and are repetitive. Accommodation typically occurs due to repetitive stimulation and long pulse duration.

sanakey – highly effective. Treatment time 5 – 20 minutes.

TENS – requires prolonged use for effect.

How does sanakey work?

sanakey is the latest development in non-invasive interactive neurostimulation technology, The nature of the sanakey‘s interactive neurostimulation technology allows for evidenced based applications that optimise certain treatment parameters and gives consistently good results across a broad range of painful conditions, both acute and chronic in nature.1 2

Using a highly variable impulse, sanakey is an effective, non-invasive medical technology, which works by stimulating the body’s inherent pain relief and self-healing mechanisms. Its direct effect is several times stronger than of other physiotherapeutic devices, with no undesirable side effects.3 4 5 6 7

The sanakey personal pain relief device is designed to deliver general therapeutic non-invasive therapy to the body’s physiological systems via skin areas, in order to effect pain management and pain relief. When the sanakey is applied to the skin, electrical impulses adjust and change, the devices read changes in the electrical properties of the skin. This interactive neurostimulation may not only provides sustained pain relief, but does not allow the body to accommodate the signal or develop a tolerance to the signal.

When there is pain or trauma to any area in the body the response from the nervous, endocrine and immune systems is to release what we call regulative peptides appropriate to the injury and initiate pain reduction and the healing process. This is what generally happens when the body is healthy!

There are times however when the body’s healing process is slow or incomplete This can come as a result of a number of factors:

  • Lack of, or a disruption to, the communication (energy – information) systems in the body, meaning that messages cannot reach their ‘target’.
  • Lack of response from the nervous, endocrine and immune systems.
  • Low priority to the injury, meaning the body’s healing resources are directed elsewhere.
  • Low energy or vitality in the body, meaning a lack of intrinsic healing resources.

If the body is unable to effect healing (for whatever reason) it may isolate or disconnect from the dysfunctional area and not apply any more healing to it.

“Regulative peptides regulate almost all life processes on the cellular level, thus linking together all body systems. They have been referred to as the body’s internal pharmacy, the ‘key in the lock’ that causes the cascading, chain reaction effect, creating an holistic body response”

These regulative peptides, once released don’t go directly to the injured or dysfunctional site. In fact, they circulate in the bloodstream and reach other injured or dysfunctional areas in the body.

In this way old and forgotten problems may also be helped to heal!

When using your sanakey, pain relief may often extend beyond the actual treatment session – often days beyond! This is one of the major distinguishing factors of the sanakey. The sanakey sends out a signal through the skin and then ‘waits for it’s return’ from the body. The device then ‘reads’ the returning signal and adjusts its own subsequent signal. Because of this interactive mechanism, each new impulse differs from the previous one, thus overcoming the body’s accommodation to the signal.
