Scientific basis of the ReadingOCI dyslexia treatment method
Doc. Tapani Rahko has tested some 10 000 patients during over 10 years with his positional vertigo tests. The age varies from 3,5 years to 94 years.
The reading speed has been measured before and after positional treatments in some 3500 cases to obtain information on the effect. The result was better after treatments.
The first peer reviewed report on the effect to the reading and learning problems was in Finnish Medical Journal2003; 39:3883-3886. The detailed method was described in net appendix
The tests and treatment to superior canal have been published peer reviewed in international scientific journals and cited in other publications Eur Arch Oto Rhino Laryng2001;258:112-115 and Clinical Otolaryng 2002;58:392-395
The explanation to peripheral eye movement disturbance background is verified by Ram-Tsur et al Investigative Ophtalmology and Visual Science 2006;47:4401-4409.
The reading speed increase was 40% and words were read more correct.
The mathematics results were 2 or more numbers better in a third. It probably relied on that the questions were easier to understand, when they were seen. The same trend was seen in other subjects.
2005 adult material with Hatara and Hakkarainen with Niilo Mäki Institute tests the results were of the same order (unpublished)
In Rahko material 335 patients the results were the same again ( unpublished)
With Yliherva and Rantala in Puhe ja kieli 2007;27:2,81-90 again the same results.
2009 In Sotek Foundation project in Kotka on the youngsters the results again the same.
In the newest material 2007 with Yliherva ,Rantala, Veteläinen Haapalehto and Kataja ( as manuscript) a randomized positionally treated dyslexia child material got better hearing cognition and better short term memory ; hearing pseudowords in NEPSY test and remembering number series in WISC III. The p values were in former <0.0005 and latter p<0.02.
Untreated and normal children shoved no statistically significant change.
Even these possible backgrounds of dyslexia got better with this treatment.
Right-left discrimination gets normal.
The coordination gets normal.
In part of the motor problems regarded as inherited changes are seen.
The compensatory muscle tension disappears unnecessary. This creates vasodilatation and the changes dependent on that will appear.
The eye movement guidance problems diminish; double vision etc.
The problems in visual feed and auditive feed canal produce frustration and the person may develop disturbing compensatory behaviour types. A part of these regarded as independent psychiatric diseases will disappear, when cognition and learning capacity improve. In young children the phenomenon was very clearly seen, because the children could maintain thus the interaction with their social group as equal members of the group. The self-esteem as if exploded, when the children could communicate at the same level as others. The material has been collected.
Equally the simultaneous symptoms motion sickness, acrophobia, agoraphobia, afraid of lifts and narrow places are got rid of.
What will be done: When you have positional vertigo or milder form OCI ( Otolith Canal Irritation) otoconias, very tiny calcium carbonate granules, get moving. The function of these is to tell with their bigger inertia to underlying nerve cells in utricle to which direction the movement is and how much.
A part of population has inherited a tendency of these otoconias to wander to semicircular canals..
This phenomenon is more common as believed. It is now found with more sensitive tests.
There are three canals on both sides: posterior, horizontal and superior or anterior.
The granules produce random disturbances in the rotation analysis input and the guidance of the eye movements is deficient. Thus the picture born at retina is inaccurate and is fixed in brain as inaccurate memory imprint. Its quality and processing presumes more workload by the brain and the result is worse.
The sight is quite bad. The sight in foveolar area is inaccurate. The width of the sight field as accurate is quite narrow. ( The effect on driving ability might be interesting). This phenomenon imitates a central process, although the problem is of peripheral origin. The appearances deceive.
When the positional treatments to all three canals are performed, jumping of lines, to and fro reading , interspace difficulties of words and guesswork disappear. Thus we have more capacity to process the text, not only concentrate on looking, what is to be seen. That gives the additional capacity to process to the brain; the basis of the problems is not the lacking structural central brain capacity. It is just functional and can be corrected. The continuous treatment is mandatory. Why wait until there are problems. Through cleaning of the canals the acceleration and movement analysis input is accurate continuously and thus eye movement guidance.
The strict structural models must be broken and functional models are added. The plasticity and capacity of the brain is immense as eg. Merzenich states.
All the canals must be treated. The historic assumption of the necessity of visible nystagmus excludes smaller disturbances, which disappear in noise, but produce the problems. The often expressed relation of vertigo to nystagmus is not linear; without nystagmus there are quite much equilibrium phenomenons. Thus the clinical results justify methods, nystagmus is not the criterion; it is just easy to observe and measure, and has thus gained unjust position in vertigo studies.
Structural brain deviations and problems naturally exist, but their amount is much less than proposed. Plasticity is the key.
It is sensible to abolish the peripheral visual component of dyslexia in an half hour process.
The persons usually have some of the following symptoms
acrophobia, agoraphobia, motion sickness, lift and narrow place phobia, aviophobia, panic symptoms.
They are not able to read in car,difficulties in carousell, difficult to discriminate right and left, skating , downhill. ballet, dancing to some direction.
Children must be followed if they:
don't climb, are accident prone, run with broad feet stance in short steps, are clumsy
They may screw their eyes, speech may be difficult in different ways, cognition problems, different delays, concentration problems, inability follow the social scene. hyperactivity, adhd, add, coordination problems.
The materials have been collected.
This method is honed to a practical tool with very large material during seven years and will be distributed globally.

Following pictures illustrate these phenomenons described above

The comparison of usual pc input functions to the way as the brain processes input information: The case dyslexia
nystagmus computers 1978 and. 1985 The law of Moore is seen . The first was Motorola 6800 based, the latter between 286 and 386 capacity.
The way of computer analysis in equilibrium study ended to too narrow a scope of observations in too complicatedly compensated network system. The clinical results give the best evidence of the real benefits of different treatments. That is natural
