 (Presented to Seattle Dizzy Group on 4/13/19)

This presentation gives an overview of cervicogenic dizziness including common causes (such as neck, head, or brain injury), signs and symptoms, and how physical therapy can help.

What Is Cervicogenic Dizziness?

Cervicogenic Dizziness (CD) is dizziness associated with neck dysfunction and/or pain caused by direct injury to the neck. To understand CD, a basic understanding of the anatomy and pathophysiology of the neck is required.

  • The Neck Is Composed Of:
    • Seven vertebrae (bones of the neck)
    • These bones come together and form joints of our neck called facet joints
    • In-between these joints, nerves exit
    • Our neck has deep and superficial muscles

  • How Does Our Neck Help Us Balance?
    • Within our muscles and joints we have small sensors that send information about where our head/body is in space.
    • This information travels up the neck, through our nerves and into our brain.
    • These sensors are activated when our muscles stretch and shorten, or when our joints bend with movement.
    • This system is called proprioception.

Neck muscles

Possible Pathophysiology Of Cervicogenic Dizziness

  • It is believed that injury to the neck may interfere with the balance system by damaging muscles, joints, or nerves that send proprioception information to the brain.
  • Proprioception is one of many systems that help us maintain balance.
  • Our brain uses multiple systems/senses to help us balance:
    • Vision
    • Touch
    • Vestibular (inner ears)
    • Proprioception
  • All of these systems must come together in a process called “sensory integration” for us to balance properly.
  • If one system, such a proprioception, is sending inaccurate information or contradicts the information from other systems, this can trigger dizziness.
  • It is important to note that currently the pathophysiology of CD is theoretical and mostly based off of animal studies.

Balance sensory integration

What Are Common Causes Of Cervicogenic Dizziness?

Mechanical forces that cause inflammation or irritation of nerves, muscles, or facet joints in our neck, which may cause altered proprioception signals.

  • Common Causes:
    • Chronic neck pain: creating general neck stiffness and muscle tension
    • Whiplash Associated Disorders (WAD)
    • Concussion
  • Gate Control Theory of Chronic Pain:  Before they can reach the brain, pain messages encounter “nerve gates” in the spinal cord that open or close depending upon a number of factors (possibly including instructions coming down from the brain). When the gates open, pain messages “get through” more or less easily and pain can be intense. When the gates close, pain messages are prevented from reaching the brain and may not even be experienced. Pain messages may be overridden/modulated by other signals/inputs such as massage, heat, cold, TNS (transcutaneous nerve stimulation), acupuncture, etc. (Information from: www.spine-health.com/conditions/chronic-pain/gate-control-theory-chronic-pain).
  • Whiplash:  Neck injury due to forceful, rapid back-and-forth movement of the neck
    • This “whiplash” motion occurs during motor vehicles accidents, unexpected falls, or any direct blow to the head.
    • The quick “whip” like motion of the neck can cause muscle and joint damage.
    • Common symptoms of Whiplash Associated Disorders (WAD):
      • Neck pain, stiffness, muscle guarding, tension
      • Abnormal posture and movements:  moving “on block” or very rigid
      • Dizziness and instability
        • Dizziness correlates with high levels of neck pain
        • Only a small portion of patients suffering from WAD will experience dizziness

Whiplash

  • Concussion/Traumatic Brain Injury (TBI):  An injury to the brain that results in temporary loss of normal brain function.
    • There are two different mechanisms for sustaining a concussion:
      • Coup:  Occurs at the location of the initial impact
      • Counter Coup:  Occurs opposite of the initial impact due to momentum pushing the brain into the skull
    • Concussion may be caused by rapid head movement (without any direct hit/impact).
    • Head injuries may have concomitant neck injuries due to the high forces of the direct blow causing joint and muscle damage.
    • Often times prolonged concussion symptoms may be caused by undiagnosed neck dysfunction, including WAD and CD.

Symptoms Of Cervicogenic Dizziness

  • Whiplash and Concussion/Traumatic Brain Injury may cause “sensory integration” problems resulting in vestibular symptoms such as:
    • Dizziness
    • Imbalance
    • Headache/Migraine
    • Vision Problems
    • Brain Fog
  • The onset of vestibular symptoms may be delayed 1-2 weeks after injury.

How Physical Therapy Can Help

  • Head and neck injuries as well as sensory integration problems may be improved with physical therapy exercises.
  • Usual recovery with physical therapy is about 3-6 weeks (for about 50% of patients).
  • If regular activity is resumed too quickly prior to fully recovering from injury and sensory integration problems, the patient may decompensate and experience a relapse of symptoms.

Functional Neurology and Neuroplasticity

Functional Neurology

Functional Neurology & Neuroplasticity

Help Your Brain, Help Your Body

by Dr. Daniel Hanson, D.C.  D.A.C.N.B

of Hanson Chiropractic Neurology 

 (Presented to Seattle Dizzy Group on 3/16/19)

This presentation gives an overview of functional neurology including how brain-based therapies work to promote natural healing through neuroplasticity which can help improve balance and reduce chronic vestibular symptoms such as dizziness, headache, and brain fog.

What is Functional Neurology?

Many people with neurological or vestibular/balance disorders suffer from debilitating imbalance and dizziness/motion sickness (feeling of being on a boat, spinning of the room, abnormal sensations of movement, etc.).  Functional neurology utilizes chiropractic techniques and specialized therapies to restore balance in the musculoskeletal, cerebellar, vestibular, and cortical system. Personalized functional neurology exercises create neuroplasticity which helps to alleviate a patient’s chronic symptoms and improve their balance issues.

  • Conditions Functional Neurology Can Treat:
    • Balance Problems
    • Dizziness
    • Headache
    • Brain Fog
    • Chronic Pain or Fatigue
    • Mal de Debarquement Syndrome

Neuroplasticity

What is Neuroplasticity? 

Neuroplasticity is the ability of the brain to reorganize itself, both in the structure and how it functions.

  • How does it work?
    • “The brain that fires together, wires together”
    • Cellular Immediate Early Gene Production
      • Leads to mitochondrial production of protein (i.e. “the building blocks of life”)
  • How do we implement this?
    • Brain-based therapies in clinic and functional neuro exercises specific to the individual for homework

What are the Benefits of Functional Neurology & Neuroplasticity?

  • Long Term Results
    • Works best with intensive programs
  • “Plastic” Change
  • Overall brain health improved
  • Influence any aspect of your life!

Advancements in Restoring Balance & Hearing with Prostheses

Cochlear implant

Treating Chronic Vestibular & Hearing Loss with Cutting Edge Implanted Devices

by James Phillips, PhD

Director of the Dizziness & Balance Center at University of Washington Medical Center 

 (Presented to Seattle Dizzy Group on 11/10/18)

This presentation gives an overview of vestibular and auditory prostheses including how the University of Washington Medical Center is currently evaluating these cutting edge implanted devices which will hopefully help to improve the quality of life for many with chronic vestibular and hearing loss.

What is the Vestibular System?

  • The vestibular system includes the structures in the inner ear that contribute to balance and orientation.
  • It includes the nerves that relay balance and orientation information from the inner ear to the brain.
  • It includes the neurons in the brain that make sense of that information, by combining information from a variety of sources:
    • different parts of each inner ear
    • from both ears
    • from the visual system
    • from the muscles and joints

Balance System

What Parts of the Inner Ear are Parts of the Vestibular System?

  • Semicircular canals
    • Posterior canal
    • Lateral canal
    • Anterior canal
      • Detect turning
  • Otolith organs
    • Utricle
    • Saccule
      • Detect front-back, right-left, up-down
      • Detect tilt
  • Vestibular Ganglia

The Internal Ear

What are the Semicircular Canals?

  • 3 canals (posterior, lateral, anterior)
  • Orthogonal
    • Fluid filled
  • Ampula
    • Location of hair cells.  (Our sense of balance starts with hair cells!).
      • Like the hair cells in the cochlea for hearing
    • Neural transduction
      • Convert movement into neural signals

How Do the Semicircular Canals Work?

  • When you turn your head fluid moves in the semicircular canals.
  • Each ampula contains a cupula, which billows when the fluid moves, which in turn bends the hairs of the hair cells.
    • Gelatinous tongue
    • Embedded hair cells
    • Sense rotational acceleration

How Do the Otolith Organs Work?

  • The otolith organs contain a gelatinous cap (otolithic membrane) and otoliths (otoconia, calcium carbonate crystals).  They also contain hair cells.
  • When we slide or tilt, the gelatinous cap deforms, and the hairs of the hair cells bend.
    • Shear
    • Sense of tilt and linear acceleration

Otolith Organs

What Happens When the Inner Ear Vestibular System Fails Bilaterally?

Both ears fail to work:

  • No whirling vertigo
  • Significant Disorientation
    • Swimmy headed feeling
  • Nausea and fatigue
    • Conflicting sensory input
  • Anxiety
  • Cognitive Impairment
  • Oscillopsia
    • Failure to stabilize your eyes when you turn your head
    • The visual world moves when you move
    • Reduces your vision
  • Postural and Gait Instability

Is There Compensation for Inner Ear Vestibular Loss?

  • YES
  • Over time we can compensate well for vestibular loss
    • Especially true of children
    • Our brains are designed to adjust for loss of input
  • Compensation is dependent on learning:
    • not to misinterpret sensory cues from a non-working vestibular system
    • to use contextually appropriate cues
    • to develop a general strategy that is adaptive over a range of situations
    • to substitute useful information from other sensory systems:
      • Somatosensory System
      • Visual System
  • Compensation requires sensory stability
    • Defeated by change of fluctuation

Can We Replace the Inner Ear Vestibular System?

Yes, with a vestibular prosthesis!

Vestibular Prosthesis

Who Could Be Treated with a Vestibular Prosthesis?

  • Not patients with a single acute transient loss of function.
  • Patients with bilateral loss of balance function.
    • Often iatrogenic
      • Exposure to ototoxic drugs
  • Patients with uncompensated unilateral loss of balance function.
    • Large numbers of patients do not adapt to a loss from one ear
  • Patients with fluctuating balance function.
    • Meniere’s Disease
      • Extreme intermittent vertigo
        • Destructive therapy
          • Injected ototoxin, surgical ablation, nerve section
          • These devices would take the place of a labyrinthectomy
  • Usher Syndrome patients:
    • Bilateral loss of balance dysfunction
    • Combined with hearing loss
      • Usher Syndrome patients may already have inner ear implants (cochlear implants for hearing loss).
    • To effectively treat Usher Syndrome vestibular loss requires a combined vestibular and auditory implant.

UWMC Road to Human Trials

  1. Design a device to stimulate vestibular afferent fibers.
    • Leverage a highly developed existing technology
      • Cochlear implant
    • Modify the software and hardware
      • Create a minimally invasive electrode technology
      • Create appropriate stimulation strategies
        • FM not AM
    • Partner with an existing Cochlear Implant manufacturer
  2. Develop a simple surgical approach with the right target.
    • Three semicircular canals
      • Coherent rotational information
  3. Construct prototype devices.
    • Identical to the final production device

UWMC Road to Clinical Trials

  1.   Evaluate the device in animal model.
    • Implanted devices in 14 rhesus monkeys
      • Similar inner ear anatomy to humans
      • Test in intact and lesioned animals
        • Ideal model for unilateral and bilateral loss
      • Evaluate risk
        • Longitudinally evaluate inner ear function
          • Using identical clinical tests to those that are used diagnostically in humans
      • Evaluate efficacy
        • Longitudinally evaluate prosthetically elicited function
          • Using clinically relevant behavioral and physiological measures
  2. Test the device in human patients with vestibular loss.
    • In 4 Meniere’s Disease patients
      • Can the device restore vestibular function lost from the destructive treatment?
  3. Modify our devices to create a combined cochlear and vestibular prosthesis.
  4. Test the new device in rhesus monkeys.
  5. Modify our existing FDA IDE to test patients with hearing and vestibular loss with the new combined implant.
  6. Test the new device in human patients with combined hearing and vestibular loss (2 additional patients, 6 total).

Turning the Implanted Device On

  • Electrical stimulation with biphasic pulse trains
  • Produces:
    • Eye movements – eVOR (Vestibulo-Ocular Reflex)
    • Body sway
    • Sensation of motion
  • Effective vestibular stimulation does not produce:
    • Nausea
    • Pain
    • Sound sensation
    • Facial nerve activation

UWMC Research Team Conclusions

  • We know that a vestibular implant works!
  • We have tested such a device in animals and humans.
  • We have an existing approval to test these devices in patients.
  • We have built a combined vestibular and cochlear implant.
  • We are currently testing it in monkeys.
  • We are working with the FDA to modify our existing human trial to test this new device.
  • We are not the only ones doing this!  (John Hopkins is researching similar implanted devices).

Chronic Illness Dilemmas

Dilemma Question 3.png

Strategies for Making Decisions with Unpredictable Health

It can be challenging to make decisions with unpredictable health.  The uncertainty of fluctuating symptoms and fatigue makes it difficult to plan ahead and keep commitments.  A common dilemma for the chronically ill is when to say “yes” to making plans and when to say “no” to invitations.  It is important to practice self care and pacing, consider the opportunity costs and possible health impact of activities, and try to find a good balance between pushing yourself sometimes and also knowing your limits.

These articles offer suggestions for common chronic illness dilemmas:

Take Steps to Prevent Falls

 

Falls are Preventable!

The vestibular system deteriorates as we age, and as a result many older people begin to feel unsteady.  Dizziness is a common symptom affecting about 30% of adults over the age of 65 and 1/3 of adults over age 65 fall each year.  Falls can take a serious toll on seniors health, quality of life and independence.  However, falls are NOT a normal part of aging and are preventable!

More information:  www.vestibular.org/seniors

The first week of Fall each year is Falls Prevention Awareness Week with the goal of raising awareness about how to prevent falls among older adults.
