Presentation Transcript


Introduction: The Balance System

  • Integration of Multiple Cues

  • To facilitate orientation & navigation

  • To maintain

    • upright posture

    • visual focus

  • Through stimulation of

    • postural muscles

    • eye muscles


Balance Is…

the ability to control the

center of gravity

over the

base of support

in any given

sensory environment


Disorders of the Balance System

  • Can Produce:

    “dizziness,” vertigo, lightheadedness, presyncope, nausea, unsteadiness, vexion, pulsion, ataxia, diplopia, oscillopsia, ...

    With varying degrees of influence on functional health and lifestyle.


Disorders of Balance

Benign Paroxysmal Positional Vertigo

Meniere’s Disease

Vestibular Neuronitis

Autoimmune Inner Ear Disease

Trauma

Toxic Substances/Medications


Disorders of Balance

Migraine

Acoustic Neuroma

Vascular Disorders

Multiple Sclerosis

Cervical Vertigo


The Audiologist’s Role:

  • Detection

  • Assessment

  • Rehabilitation

  • Referral


Case History

  • Nature of the dizziness (true vertigo, imbalance, presyncope)

  • Timing/Duration of Spells

  • What triggers spells?

  • Other otologic symptoms

  • General Health issues

  • Neurologic symptoms


Electronystagmography

  • Recording eye movements (nystagmus)

  • Using electrodes to measure

  • the Corneo-retinal potential


Video-nystagmography


The ENG Battery

Gaze Testing

Tracking/Oculomotor Testing

Dix-Hallpike Maneuver

Positional Testing

Caloric Testing


The Dix-Hallpike Maneuver


Rotary Testing

  • Rotary Chair

  • Vestibular Autorotation Test (VAT)


VAT Results
