Horizon Balance and Dizziness Center

Therapy and Treatment

             As balance specialists, we make it our job to assess all factors and develop a specific treatment plan for you. There is significant evidence that balance training will help poor balance if the rehabilitation program is specific to the problems found in a good evaluation, performed by a qualified clinician (Medical Management of Balance and Mobility Disorders, Nashner, L., Advance for Directors in Rehabilitation, July 1999).

 

Factors that are tested and treated:

            - Amount of sway in standing

            - How you sense posture

            - Ability to reach and lean

            - How you sense balance (with eyes, inner ear, and feet)

            - Ability to balance on uneven ground

            - Leg strength and joint health

            - Foot and ankle movements

            - Endurance of trunk muscles

            - Confidence

            - Inner ear

            - Neck

 

What is important in recovery?

        Dizziness can be bad and can cause additional problems such as stress, depression and poor confidence. Usually, people will stop moving to make the dizziness better. Although holding steady helps the dizziness feel better, it does not help in recovering from it and returning to normal activities. There are two facts of dizziness: holding the head still prevents recovery, and movement of the head speeds up recovery. The exercises for dizziness are well-researched and have had over 20 years of clinical success and a 90% success rate for those who don't give up. Yes, they can increase dizziness and nausea in the beginning, but if done within tolerance, dizziness can improve. The hardest thing to convince people of is that if they stick to the program, they will improve with very few exceptions. Stay motivated and don't give up!

            - Dizziness occurs when signals going to the brain are bad.

            - The brain will stop the dizziness when it detects the bad signals and corrects.

            - When the head is moved, the bad signals momentarily make the dizziness worse but it also helps the brain to compare and correct the signals that are causing the problem.

            - Head movement equals improvement. Pace yourself and don't give up!

The Four Conditions of Recovery (Adaptation)

        In the 1940's, Dr. Cawthorne (ENT) and Cooksey (P.T.) observed that people with dizziness recovered faster when they remained active versus the people that limited their movement. They developed a set of exercises (Cawthorne-Cooksey Exercises) (1) that speed up adaptation. Adaptation is when the brain corrects the bad inner ear signals. There are four conditions of adaptation that guide treatment:

            - Adaptation is frequency dependent. The brain adapts only at the speed that it is trained. Therefore, a patient needs to train with head movements in a variety of speeds to adapt to the different demands of daily life.(2)

            - Adaptation requires time.(3) Once the signals are calibrated, symptoms should improve.

            - Adaptation requires concentration to focus the brain's attention on adapting.(4) Exercises should cause a tolerable level of dizziness.

            - Adaptation requires multiple system stresses.(5) Since there are three systems that interact (vestibular, visual, and somatosensory) exercises should vary to emphasize each system.

        The inner ear exercises are designed to speed up adaptation and improve dizziness. Assessment and treatment should be performed only by one trained in balance and vestibular disorders.

Dedication to Scientific Based Treatments

        There is a great concerned in rising medical costs. Insurance premiums are going up at alarming rates. One way to fight raising medical costs is to be efficient by using proven scientifically-based treatment models.

        The majority of the patients we see have spent months or years suffering with dizziness or balance problems, going from doctor to doctor and having a borage of expensive tests that often come back normal. How can a physician treat a problem if there is no positive findings?

        It is common to see a patient who has been dizzy with poor balance to stop their normal activities and fall into depression. Sometimes the dizziness has lasted for 10, 20, or 30 years only to be completely resolved in one to three treatments. Of course, not all balance and dizziness problems are so quickly reversed, but there is a specific order of tests that can identify many dizziness problems.

        Why should assessment and treatment be performed only by one trained in balance and vestibular disorders?

            - Patients get the right treatment

            - Less cost and better recovery

            - Complete assessment and treatment

            - Patients are well-educated

            - Limits prolonged suffering and improves the quality of life

            - Understanding dizziness reduces fear and anxiety

The Dizziness/Balance Management Model

            - Pathology Diagnosis: The diagnosis give by a physician that is supported by patient history, exam and diagnosis.

            - Impairment Diagnosis: Impairments of specific systems that limit functional activities. The functional problems associated with this may be imbalance, limits in independent walking or falls.

The primary tests to determine impairments are:

Postural Integration Tests:

            - Modified Control Test for sensory integration for balance

            - Posturography

Vestibular Testing: ENG/VNG

            - Care Plan: a written outline of the actions that will most efficiently resolve functional limits, symptoms and maximize the quality of life.

            - Surgical/Pharmacological Intervention

            - Balance/Vestibular Rehabilitation: training of impaired systems for balance with emphasis in regaining independent quality function and reduction of symptoms.

            - Progression Indicators: specific objective pre-determined tests such as functional tests, balance tests, Posturography, dizziness scale scores, and gait assessment.

            - Lifestyle Modifications: changes a person makes in a variety of areas that will best control symptoms (i.e. low salt diet or avoidance of poorly lit environments).

Lower Extremity Neuropathy and Balance

When Neuropathy is the cause of poor balance:

        It is a misconception that imbalance cannot be improved if lower extremity neuropathy is a coexisting problem. I have often heard my patients say, my imbalance is because of my neuropathy. They can make inference that if their neuropathy cannot be helped then their balance cannot be helped. They problem with this assumption is that the patient has a false preconceived negative outcome to any treatment with not hope for improvement.

        Lower extremity neuropath can reduce balance because it is one of the sensory systems involved in balance and body orientations. The most important realization that one can have is that there are two more sensory systems of balance that can be trained to compensate for lower extremity neuropathy. Permanent balance problems can exist with neuropathy but the extent of the imbalance depends on the condition of the vestibular system and the ability of the CNS (Central Nervous System) to use visual stimuli for balance. These re the two systems that can compensate for neuropathy.

        The best way to determine the functional condition of balance systems are to assess each system through an ENG/VNG and Posturography. Only with this information can a decisive and accurate conclusion be made as to the prognosis of balance.
