|
Seniors represent the fastest growing segment of
our population est > 75 Million. |
|
Dizziness and loss of Balance is the #1
Complaint for our senior population. |
|
Each year 40% of our seniors experience falls. |
|
|
|
|
Balance related falls result in more than 300,000
hip fractures annually with a mortality rate of 30% within one year |

|
Mechanisms of Balance: |
|
|
|
Internal, Vestibular- where is my head in space,
where is it moving to? |
|
Sensory Integration - at CNS level |
|
External Visual + Somatosensory |
|
Musculo-skeletal
Integrity |
|
|
|
Conflict of any three = perception of
movement without actual motion |

|
|
|
|
|
Inner Ear Hearing loss, tinnitus,

|
Internal Auditory canal Hearing loss,
tinnitus, facial weakness |
|
Cerebello-pontine angle Hearing loss,
tinnitus, facial weakness, and numbness, incoordination |
|
Brainstem Diplopia, dysarthria,
perioral numbness, extreme weakness |
|
Cerebellum Imbalance, incoordination |
|
Temporal Lobe Absence spells, visual,
olfactory, or gustatory hallucinations |
|
|
|
|
According to the National Institute of Health 60+%
of dizziness involves Vestibular disturbances. |
|
|
|
The best way to Dx Vestibular Disorders is
measure the Vestibulo-Ocular Reflex (V.O.R.) with the Vestibular Autorotation
Test (V.A.T.) |
|
|
|
|
V O R |
|
|
|
Generates eye movements to maintain clear vision while head is in motion |
|
Utilizes all vestibular and occular affarents
and vestibular nuclei |
|
|
|
V S R |
|
|
|
Generates compensatory body movements in order
to maintain head and postural stability |
|
|
|
Receives vertical vestibular inputs |
|
|
|
|
Interaction between the Internal and External
signals |
|
Normal use: to fix on a visual target while
moving the head. |
|
Reflex does not activate until head movement of >2
HZ. |
|
|
|
|
High Frequency: 2-6 Hz |
|
Active Head Movements |
|
Horizontal VOR |
|
Vertical VOR |

ENG |
|
|
|
Measures the function of only one
semicircular canal
(on the horizontal axis) |
|
|
|
Measures function at <1 Hz (non-physiological) |
|
VAT |
|
|
|
Measures the function of all three semicircular
canals |
|
|
|
Measures function at 6 Hz (physiological) |
|
|
|
|
|
Determine the patient’s current status: |
|
|
|
1. Functional Fall risk assessments |
|
Utilize the Berg, Tinnetti, and Functional Reach Tests |
|
|
|
2. Analyze current movement
strategies |
|
|
|
3. Which movements provoke
dizziness, vertigo ? |
|
|
|
4. Utilize Neurocom Balance
Master to determine: |
