Introduction – DrMagSight
The rehabilitation program focuses mainly on the ocular movements’ basal training, visual attention and the ability to distinguish figure from ground. The exercise sequence is set from the basic eye fixation training and guiding the ocular movement to more complex elements of observing point at complex background. It is not a necessary prerequisite to maintain the sequence and it can be selected during the rehabilitation based on the individual condition. The full length of the exercise should not exceed 6 minutes. Different levels of contrast can be selected for the exercise. The contrast is selected based on the individual preference and tolerance of the rehabilitated person. Decrease in contrast may lead to lower visual stress and the exercise efficiency may increase. A black text on white background is usually read, which has the best contrast, change of colours lowers the contrast. If a signal sound is used either at the beginning or the end of the exercise it stimulates the ear – eye reflex connection. The program is designed for rehabilitation work with developmental speech disorders (developmental dysphasia syndrome, developmental dysarthria, developmental disorders and learning, ADHD, sensory perception disorder during organic disease of CNS (cerebral trauma, post-CMP conditions), vertigo condition rehabilitation, or some selected sight disorders. Furthermore, it is advisable to use this program in combination with programs DrMag-Sluch (Hearing), DrMag-Zvuk (Sound) when rehabilitating hearing disorders and post-cochlear implant conditions. Individual functions and rehabilitation sections do not have any feedback value check which is intentional and left to the interaction between the rehabilitated person and the therapist. In the case of children the rehabilitation is performed under the therapist’s or parent’s supervision.
Characteristics of basic modalities of use
|Ocular movement guidance
|Variants and description of the rehab. exercise:
Left to right horizontal: A point moving in the lower arc, from left to right, is observed. The cycle is repeated based on the individual level. Recommended: no more than 4-5 times.
Left to right horizontal, line shift: A point moving in the lower arc, from left to right, is observed` the point shifts smoothly to one line below. The cycle is repeated in the full horizontal observation movement of the child and with gradual vertical shifts. Repeated based on the individual level. Recommended: no more than 4-5 times. The following ones are similar:Rehab. goal: Training of basal eye movement check level – fixation position on the left, saccade from left to right, fixation position on the right, return to the fixation position on the left. The exercises are especially suitable for developmental speech and learning disorders, and ADHD. Reduced ability to guide and control ocular movements from left to right vertically descending causes difficulties with attention to read text, difficulties with the sequence of word – line beginning in school-age children, they skip lines when reading, guess words, etc.).
Horizontal arc bidirectional, horizontal in line.
|III. Combined forms and shapes
|III. Combined movements / circle, number eight
Variants and exercise description: Observing the trace of a moving point
Rehab. aim: Stimulation at the level of controlled shifts of ocular movements in different directions in the visual field – visual attention training while the observed point position changes.
Visual differentiation weakening and position change awareness may result in slower memorizing of letters in school age children, difficulties differentiating between upper and lower positions (mixing up letters and numbers which differ in their upper-lower positions – e.g. t-j, b-p, 6-9), difficulties differentiating between right-left positions – confusing letters which differ in their right-left positions (e.g. d-b, numbers 6-9), mirroring of mostly uppercase print letters, etc.
|IV. Figure-ground distinguishing
|Variants and exercise description:
We observe the whole image/area and search for points in a non-homogeneous background. The points we observe are gradually disappearing, the rehabilitated person detects the points which have vanished.
Rehab. aim: Stimulation at the level of controlled shifts of ocular movement directions in the visual field – visual attention training in advanced perception ranges (i.e. in the visual field that provides information during one fixation).
Basic recommendations for choosing program settings options properly
|1. GRAPHIC SETTINGS
|GRAPHIC SETTINGS IN SHADES OF GREY
– decreases visual stress
GRAPHIC SETTINGS IN COLOURS
– Indicated for special cases with the colour perception disorder or accented problems with the ability to distinguish figure from ground
SETTING BORDERS OF A MOVING POINT
– Intensifies the contrast of dominant signal against background without increase in visual stress.
– accents the training of the ability to capture visual signals. Moving points should always be smaller than the chessboard square. Moving points should either be white or black. In the case of serious disorders it is advisable that the point fringe is in shade of grey.
|2. POINT MOVEMENT DIRECTION
|FROM LEFT TO RIGHT HORIZONTAL
– training of the ability to maintain visual signals in general, training of the central line transition, reading disorders rehabilitation. It is advisable to start with an arc, then move to a higher difficultylevel – movement along a line.BIDIRECTIONAL HORIZONTAL
– suitable for special rehabilitation of vertigo conditions or for focused work with vertical central line crossing problems.
VERTICAL AND COMBINED MOVEMENTS
– suitable for special rehabilitation of vertigo conditions or for focused work with horizontal and vertical central line transition problems.
|3. POINT MOVEMENT SHAPE
|ARC in the horizontal and in line shifts
NUMBER EIGHT, CIRCLE, POINTS in the segment of distinguishing figure from ground
Other possibilities to exercise, especially bidirectional movement and LINE movement
