The Sensory Integration Experience Device
(SiXDEVICE® protocol)

VISUAL PROCESSING RELATED TO SPATIAL UNDERSTANDING

‘Quickly and easily free the sensory network from rigid patterns and compensations for total systemic harmony’

Sensory inefficiencies alter the coherence of incoming information to our senses. The resulting effect is compensation leading to overuse, discomfort, or pain. This emanates in a constant search for a better position and balance to improve body function.

What is the SiXDEVICE®?

The SiXDEVICE is a sensory yoked prism with centesimal power. This slight power aligns itself with the threshold of the acceptance of any rigidly organized sensory system (dysfunctional) to regulate and harmonize visual information management (best interaction between localized and environmental/ spatial information) and to reorganize visual function.

The SiXDEVICE sensory prism is different from conventional refractive prism used in visual therapy training. Conventional prisms change the light direction in a specific retinal area versus the entire retinal and are prescribed with 15 – 285 times stronger powers than the SiXDEVICE.

How does the SiXDEVICE® work?

The SiXDEVICE prism modulates the sensory information leading to a new perceptual organization and sensory learning experience without affecting structural change [When yoked prisms of low power from 1 to 3 DP are used, the changes are unconscious, that is reflexive, and proprioceptive changes precede visual ones. When high powers are used the changes are conscious and an immediate reorganization of the neuromotor system is forced to meet the new transformed demands of the environment (M. Kaplan)].

With their light diffusion feature, the very low power SiXDEVICE creates an instantaneous sensory effect along the trigeminal pathway, and trigeminal sensory nuclei complex (TSNC). If the system is dysfunctional (wrong network feedback), it is not able to self-organize and support the body networks during the reception of information (aberrant neck, shoulders, TMJ, etc., position, ROM, and muscular strength). SiXDEVICE can improve coherence through the self-organizing mechanism of feed foreword activity. In this sense, the SiXDEVICE acts along the way of the superior colliculum and the cerebellum, (the way of learning and automatism), modifying the perception of visual stimuli with relevance on proprioception, sensory integration, and activity of extra ocular muscles for system integration (OCR). Retino collicular pathway is the fastest retinal pathway to reach the brain and it is constantly active with both open and closed eyes (Zelinsky) .

SiXDEVICE should be used for a few hours with cyclical ON / OFF daily. Usually after one month of use, positive reliable and repeatable results regarding the harmonization of sensory information are found in most of the patients.

The device induces retinal peripheral fibers to be activated, harmonizes and balances visual information, and makes it easier to integrate information from different sensory systems through sensory and motor relays. The trigeminal nerve represents the common innervation pathway between the visual receptors, the masticatory receptor, the cranial base and the upper cervical spine (O-A). It is possible to observe the immediate sensory and motor efferent responses along the trigeminal pathway when visual information is altered.

The relationship between the visual system and the stomatognathic system should consider the parallel between the trigeminal cranial nerve and the cranial nerves supplying eye extra ocular muscles (V and III, IV, VI CN), known as the (Cervical) Ocular-Trigeminal convergence. In fact, between these nerves there is a synaptic connection [(Wühr) M. Friedrich].

Through these connections, we can explain the intense interaction between the function of the visual and upper respiratory network’s feedback, whereas a TMJ tension through a collapsed midface (Dibbet) can involve functional visual discomforts, this include accommodative and visual disfuntions, constricted visual fields, dry eyes and intra ocular hedache. The same will be true in reverse (M. Friedrich). We can assume that the SiXDEVICE becomes a feed forward activity for TSNC helping to regulate system networks biofeedback for self-regulation.

 

The SiXDEVICE re-adapts and reorganizes the information that ends up in the TSNC. The TSNC has extensive projections to other areas of the TSNC, to motor neurons in spinal cord and brainstem, to the cerebellum and basal ganglia, and via thalamus to the motor cortex. Muscle of the face, eye, jaw, and neck are innervated by projections from the TSNC to motor neurons in the facial and trigeminal motor nuclei, to motor neurons located in the upper cervical spinal cord and to the superior colliculus. From the mesencephalic nucleus proprioceptive neurons project to trigeminal motor nucleus, the retinacular nuclei, the cerebellum and as far caudally as the upper cervical cord.

 

Neurons of the principal sensory nucleus ascend to the thalamus, superior colliculus, cerebellum, and trigeminal and facial motor nuclei. Principal sensory nucleus neurons project to the inferior olive and the hypoglossal nucleus. Neurons of the spinal trigeminal nucleus project caudally to mid and lower cervical motor neuron innervating neck muscles. Rostrally, the spinal trigeminal nucleus project to the thalamus, the superior colliculus, and the cerebellum via the inferior olive.

Because of those feedback loops “TSNC is a key structure in large neural network modulating activity in motor neurons supplying muscles of the neck and face, it influences body self-organization and learning”.

 

Through consistent and predictable integration of all the information coming from different subsystems the SiXDEVICE improves the body’s own learning capabilities strengthening its own intelligence.

The SiXDEVICE® philosophy:

  • Considers how to process information through the ability of visual function examining the relationship of the visual receptor along the path of the trigeminal nerve, motor nuclei, and trigeminal sensory nuclear complex (TSNC); how to correctly assess and interpret symptoms as a consequence of inefficiency of the sensory system.
  • Addresses problems with timing (desynchrony) and sequence (asynchrony) not reachable with other methods, through improving system relationship and freeing the body from rigid schemes to allow the person to receive and utilize multisensory information.
  • Helps to optimize respiratory function, biomechanical performance, and multisensory management through improved: regulation of muscular tone, range of motion (ROM), muscle strength and coordination to regain homeostasis. This can be assessed based on systemic predictions versus systemic reactive responses to stimuli (MMT).
  • Provides licensed professionals a tool to regulate (inhibit and/or facilitate) change via neural plasticity in teaching new information to their patients. Is the logical access port to assess the sensory system though its procedures and methods of use, and it works with the patient’s skills to improve their system self-regulation.

PROTOCOL

 The SiXDEVICE® protocol is organized to achieve a balance in the unique relationship between visual harmony – sensory efficiency – leading to freedom and ease of movement. The meaning of the tests selected is to interpret the efficiency response of the system through SiXDEVICE® philosophy.

 Visual Harmony facilitates the system and rectifies the processing capabilities that represent the essential elements to be aware of the perception of position in space. An inefficient system is refractory to stimulus, considers and process various information with foreclosure of the integration organizational modality (dysfunctional); on the other hand, an efficient system is receptive, interacting and in harmony with the incoming information modules, which activate the system in its functional integrity. System efficiency can be perceived, analyzed and scrutinized through the SiXDEVICE protocol procedures. The sensory system responds in a fraction of a second to the stimulus through a series of subjective and objective signals:

  • Increased cooperation response of visual receptors associated with freedom of exploration (push – pull mechanism) and reduction of the excessive head or body movement, depending on the spatial position [(socket on the globe and head on the body movement, this is egocentric to allocentric) Spatial Perception Challenge Test].
  • Improvement of the environmental interpretation compared to the response of the stimulation system. It improves spatial perception that easily integrates vestibular, podalic and somatosensory information [(this is allocentric to egocentric) Awareness Ability for Information Integration Test, and Space Selection and Comprehension Test].
  • Through sensory integration the motor scheme is more available with higher quality of movement and less energy expenditure. This promotes system neutrality and its perceptual openness with immediate improvement in the range of motion (ROM) of the trunk, neck, and extremities including TMJ [(homeostasis) Applicative Integration Test].
  • Increase in static and dynamic perception and proprioception with optimized equilibrium (Applicative Integration Test).
  • Reduction or disappearance of the discomfort associated with the task required during the execution of the test: tension in the ocular movement, double vision, tension at the base of the cranium and neck, headache, jaw tightening, restriction of breathing, disequilibrium, nausea (All Information Network Loop Tests).

Protocol steps:

In the common approach (quantitative), the visual ability tests aim to assess the potential association with it through a procedure aimed at evaluating binocular vision through a linear relationship of functional tests that evaluate the sequential effects with measurements of:

fixation -> fusion -> binocular vision

 The SiXDEVICE philosophy (networks regulation and qualitative approach) does not consider single function but monitors and evaluates how the system organizes during the tests (feedback). With this philosophy, events occur simultaneously in a network loop and not sequentially. The selected tests involve the processing functions in multi-sensory mode, the test battery must be repeated wearing SiXDEVICE and compared the effects of the responses to the tests.

 “In our approach, with respect to quantitative relationships, we strive for quality results reflected by an integrated system”

Evaluation of the system’s responses while interacting in multisensory environment

The various tests require a harmony of localized and environmental information that represent an adequate capacity for multi-sensory reception and integration. In order to administer the test, the subject should be standing in a well-lit area with multisensory stimulation (person shouldn’t be tested in sterile environment). While performing the tests, all signs of aberrant motion, fatigue, and discomfort related to the examination must be recorded: tension in ocular movement, eye discomfort, tension at the base of the cranium and neck, headaches, mandibular tension, disequilibrium, restriction of breathing, nausea, mental fogginess, double vision, etc.
