How do we achieve balance?
Three separate components make up “Equilibrium Triad”
Input from the eyes (vision) Input form the muscles and joints
(proprioception) Input from the vestibular organs (balance)

![Page 8: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/8.jpg)
Causes Pediatric Vestibular Disorders
Head/neck trauma Chronic ear infections Maternal drug/alcohol abuse CMV Immune-deficiency disorders Meningitis Migraine Metabolic disorders (e.g., diabetes) Ototoxic drugs
![Page 9: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/9.jpg)
Causes Pediatric Vestibular Disorders
Neurological disorders (CP, Hydrocephelus) Genetic syndromes (e.g., Wallenberg, Usher,
CHARGE) Posterior brain tumor Family history of hearing loss/vestibular issues Cochlear implants Lack of use - movement issues, fear, ill health
![Page 10: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/10.jpg)

VI Registry - 84 or 14%
CP - .3% CHARGE - 7.7% CMV - 2.7% Hydrocephaly - 1% Meningitis - .5% Shaken Baby - .5% Usher 1 - 1.7%
Deafblind Census - 147 or 19.9%

So how does the vestibular system work?
![Page 12: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/12.jpg)
Vestibular organs Located in the bony
chambers of the skull in the inner ear
3 semi-circular canals positioned in different planes for rotational movements
Otoliths (Utricle and Saccule) for linear accelerations
![Page 13: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/13.jpg)
Semicircular Canals Bulge at base of canals -
ampulla Ampulla contain sensory
receptors for each canal Canals filled with endolymphatic
fluid and surrounded by perilymphatic fluid

Vision and Balance
![Page 16: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/16.jpg)
Vestibular Occular Reflex Normal head rotation: eyes move in
opposite direction of head to stabilize retinal image (VOR)
Conflicting sensory information from visual and vestibular senses is a problem
The cerebellum repairs “slippage” Demonstration
![Page 17: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/17.jpg)
What Part Does Proprioception Play? Sensation experienced by muscle and joint
receptors Requires a normal range of muscle tone to
work properly Feeds information to the brain that allows
for awareness of where body parts are in space, movement, speed and direction of movement

A Redundancy for Balance
Brain and Spine Foundation Online
When one of the three parts of the Equilibrium Triade do not work or work well, the other two can compensate.

From Jean Ayers Sensory Integration and the Child
“The vestibular system is the unifying system. It forms the basic relationship of a person to gravity and the physical world. All other types of sensation are processed in reference to this basic vestibular information.”
![Page 21: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/21.jpg)
From Jane AyersSensory Integration and the Child
“The activity in the vestibular system provides a “framework” for the other aspects of our experience. Vestibular input seems to “prime” the entire nervous system.”
![Page 22: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/22.jpg)
From Jane AyersSensory Integration and the Child
“When the vestibular system does not function in a consistent and accurate way, the interpretation of other sensations will be inconsistent and inaccurate, and the nervous system will have trouble ‘getting started.’”
![Page 23: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/23.jpg)
From Carol Stock KranowitzThe Out-of-Sync Child
“Gravitational insecurity is manifested by abnormal distress and anxiety in reaction to falling or the possibility of falling. It is a primal fear.”
![Page 24: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/24.jpg)
From Carol Stock KranowitzThe Out-of-Sync Child
“Indeed, our need to know where we are in relation to the earth is more compelling than our need for food, for tactile comfort, or even for a mother-child bond.”
![Page 25: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/25.jpg)

What do we do?
TEAM
With OT knowledgeable about SI to develop menu of interventions
To plan flexible schedule related to fatigue and need for breaks
To select / train staff to respect individual differences in behavior, performance, pacing
With family to gain insight to home challenges, child preferences and for support
![Page 30: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/30.jpg)
What do we do?
MODIFY
Seating to address postural concerns Positioning for visual and auditory tasks Materials and learning environment
(isolate lines of text, reduce distractions) Activities to incorporate SI approaches Pacing Schedule (general / day-to-day) Staffing patterns
![Page 31: TETN # 30910 Visually Impaired Students with Vestibular Issues Presented by](https://reader035.vdocument.in/reader035/viewer/2022062520/56815da8550346895dcbd57f/html5/thumbnails/31.jpg)
What do we do?
RESPECT
Student challenges in learning Family struggle to address
challenges / knowledge of the child Staff challenges to adapt
programming and the expertise each has to offer
