Slide 1
What do you do with a patient who presents with any of these balance problems?
Anyone with a history of head trauma  with dysequilibrium, dizziness and/or vertigo, falls
History of exposure to environmental/chemical toxins
Patients undergoing Chemo or Antibiotic Therapy
Whenever an ENG is indicated consider the VAT and the Balance Master
Any senior with Hx of Falling or imbalance at risk of Falling
Post CVA, Parkinson, Alzheimers c caregiver.
Post Joint replacement, hip or knee and amputees, ak or bk.
Three Objectives to Learn
1)  Falling can be prevented
     Regardless of Age
A Dangerous Loss of Balance
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..."
Balance related falls result in more than 300,000 hip fractures annually with a mortality rate of 30% within one year
"Solving the Problem:"
Solving the Problem:  Diagnostics
Identifying individuals at risk

P.E.
Dx Testing
VAT
Balance Master
Audiometry
BSR

Solving the Problem: Rehabilitation
  The Treatment

Key Protocols Developed from Specific Diagnostic Finding
Individualized for Each Patient

Slide 9
What causes Dizziness?
Balance occurs at an unconscious level
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
Central Sensory Integration
Cerebro-vascular atherosclerosis
Cerebellar atrophy
Other Central Neuropathies
Post stroke
Trauma, chronic or acute
Poly-pharmacy
Slide 12
"Berg Balance Test et al"
Berg Balance Test et al
14 elements which provides a quantitative prediction of chance of falling
"Specific Hx focusing on systemic..."
Specific Hx focusing on systemic disease that can cause dizziness and balance disorders:
"Specific Hx focusing on Stabilizing..."
Specific Hx focusing on Stabilizing Sensory &
Integration Systems that can cause balance disorders:
"Dizziness:"
Dizziness: assoc sx’s and anatomical locations
Inner Ear Hearing loss, tinnitus, pressure, pain
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..."
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.)
Vestibulo-Ocular Reflex
vs
Vestibulo-Spinal Reflex
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..."
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.
VAT Characteristics
High Frequency: 2-6 Hz
Active Head Movements
Horizontal VOR
Vertical VOR
Testing in the Light
Comfortable - Repeated Testing
Portable - Bedside Testing

"ENG"
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"
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:
          C.T.S.I.B. - Clinical Test for Sensory Integration of
          Balance
          L.O.S  -  Limits Of  Stability

"Balance Retraining - addresses non..."
Balance Retraining - addresses non-vestibular disorders, decreased mechanical stability
Vestibular Rehabilitation - visual exercises with head and body movement
BPPV - Benign Paroxysmal Positional Vertigo
Self-Directed - exercises continued at home
"Patient’s with or without vestibular..."
Patient’s with or without vestibular dysfunction but with significant visual, musculoskeletal, or somatosensory deficits
P.T. focus on enhancing function of non-affected faculties
Basis of Support Exercises
Muscle strengthening exercises
Learn a variety of Movement Strategies
"Adaptation"
Adaptation
Gaze stabilization exercises - re-adaptation of CNS to differential vestibular inputs
Substitution
Strengthen remaining sensory inputs to compensate for decreased or damaged input
Effects of Vestibular Rehab on Dizziness and Balance
         Prospective, blinded Outcomes for 3 groups:
Pt’s in Customized Program of Vestibular Rehabilitation and Balance Retraining
Pts in General Conditioning Program
Pt’s receiving Rx’s:, Dramamine, Meclizine, etc.**
After 6 weeks, only Vestib Rehab Decreased Dizziness;  . .  Horak et al, Otolaryg Hd & Neck Surgery 106:p175;
Problem Oriented Approach
 Customized Disease Management
Obtain an Extensive Medical History
Determine Precise Diagnostic Information from Advanced Instrumentation
Identify all Problem Areas during the Evaluation
Treatment Progression
Increase and alternate speed of exercises
Perform exercises in various positions and activities (sitting, standing, walking, obstacles, etc).
Exercise in decreasing visual &/or somatosensory input (eyes open,closed, feet together, wide apart, etc.
Change Environment (Curbs, grass, stairs, malls, walking in neighborhood, etc.)
67 y.o. mechanic with a  2 yr Hx of dizziness, progressing to disability.  Rx Meclizine without relief.

This is a summary slide of VAT test taken BEFORE VOR retraining.  Note grossly abnormal vertical gain and phase.
Same patient as last slide became asymptomatic after only 3 therapy sessions with the VOR retraining exercises.

Note that the vertical gain and threshold in the VAT tracings were NORMAL.
Case Study: 85 yo Male, Recent Multiple Fall Hx,  Fear of Falling

"Falling related injuries - Major..."
Falling related injuries - Major contributor to senior morbidity and mortality
Effective screening can ID who’s at risk
Accurate Dx:
Quantitation of Vestibular and Balance function now possible with VAT et al testing
Testing is non-invasive and convenient
"Successful treatment of most Balance..."
Successful treatment of most Balance-related Disorders that resulted from Disease and/or Injury
Results:
     _ 75%+ Returned to normal or
        near normal function
Seniors reacquire their active lives
Reduce their Fear of Falling
Decrease their morbidity and mortality from Fall related injuries by 1/3
