A method with an objective basis

PNV stays true to the principles of the Quertant Method, established by Georges Quertant

Georges Quertant was a French researcher and pioneer in identifying and correcting certain nervous system dysfunctions. In developing his Psycho-Sensory Culture (CPS), later known as the Quertant Method, he created a fully-fledged discipline. The goal was as ambitious as it was simple: rehabilitating the functioning of the nervous system, through neuro-sensory exercises.

Oculomotor function – an accurate and reliable gauge for a training based on the principle of biofeedback

PNV is neuro-visual in that it uses the close link between eyes and brain, well-established in neuroscience, to affect and change the nervous system’s functioning.

It is practiced on devices derived from diploscopes that can present images in specific modes of vision (simultaneous perception with or without binocular fusion).

If the image presented is perceived correctly, then the nervous system has reacted appropriately and positioned the eyes accurately. If not, then the brain was not able to receive, integrate, and produce an appropriate response.

Inappropriate vergence eye movements, which distort the visual perception of a test-image, are very subtle and nearly imperceptible to the naked eye. The extreme precision of these eye movements cause them to be especially susceptible to a nervous system dysfunction, and make them a first-rate indicator for detecting such conditions.

Whatever the origins of these inappropriate reactions, you can train yourself to gradually correct them and maintain an appropriate nervous response over time.

And so PNV is objectively based and functions on the principle of biofeedback.

What are the defining features of a neuro-sensory training such as PNV?

– It requires no intellectual or analytical effort
It works simply by visually maintaining the test images in place. PNV resembles a kind of athletic training, only carried out on a more subtle level by the nervous system. The PNV practitioner plays the role of the coach, supporting you along the way.

– The results obtained are stable and acquired for life
Change is established progressively through regular and repeated training sessions. PNV is therefore not a “magic pill”, which is why its results are long-lasting. You can serenely look to the future, without fear of a relapse.

– You can observe your progress throughout the training
The neurosensory training ends when the last of the increasingly complex exercises no longer pose any difficulty. There is therefore an objective end to this method. However, its benefits can be felt all along the process and you can objectively observe your progress when you can easily carry out an exercise that used to pose problems.

– PNV is complementary with other approaches
Our experience shows that, often, reestablishing a more balanced functioning is enough to get rid of problems that seemed purely somatic (physical) or psychological. Nevertheless, nothing prevents one from practicing other therapies at the same time (osteopathy, psychotherapy, acupuncture, kinesiology, etc.). On the contrary, the synergy between different therapies is known to yield more rapid and effective results.
