Circuit Training on Vertigo, Oscillopsia and Dizziness in Vestibular Hypo Function Hypo- Functions

March 29, 2021 updated by: Riphah International University

Effects of Circuit Training on Vertigo, Oscillopsia and Dizziness in Patients With Vestibular Hypo-function

In this research, the main purpose is to determine the effects of Circuit Training consisting of Structured Vestibular rehabilitation Program under the strict supervision of Neuro-Therapist versus Medicines and General (simple) Rehabilitation (only Home-based) in community-dwelling population of people diagnosed with Vestibular disorders. A booklet consisting of general instructions, simple vestibular exercises which are to be made a part of daily routine, specific diet plan and specific precautions to be taken by patients reporting with vertigo, oscillopsia and dizziness will also be provided to all the patients. This is a community service addition, added so that everyone in the society can have easy access to the instructions, will be cost effective, and will reduce their visits to the therapist.

Detailed Description

People diagnosed with vestibular disorders often experience dizziness , oscillopsia, trouble with vision, balance or mobility. The vestibular disorders that are called unilateral and peripheral (UPVD) are those that affect one side of the vestibular system (unilateral)and (BPVD) are those affect both sides of the vestibular system (bilateral) and only the portion of the system that is outside of the brain (peripheral-part of the inner ear). Examples of these disorders include benign paroxysmal positional vertigo (BPPV), vestibular neuritis, labyrinthitis, one-sided Ménière's disease or vestibular problems following surgical procedures such as labyrinthectomy or removal of an acoustic neuroma. Vestibular rehabilitation for these disorders is becoming increasingly used and involves various movement-based regimes.

Dizziness, oscillopsia and disequilibrium are common complaints reported by adults during visits to their doctor. Dizziness, oscillopsia, vertigo and disequilibrium are not a disease-they are symptoms that can result from a vestibular disorder or from difficulties unrelated to the inner ear, such as cardiovascular, neurological, metabolic, vision, or psychological disorders. However, as many as 45% of people with dizziness symptoms have problems in the vestibular system (balance organs of the inner ear.

Vestibular rehabilitation therapy (VRT) is an exercise-based program for reducing the symptoms of vertigo, dizziness, oscillopsia and disequilibrium with vestibular pathology (disease or disorder). A common neuro-otological approach for managing such symptoms is to prescribe medication that suppresses vestibular function. However, in the long term, such suppressants can interfere with a person's ability to make necessary adaptations. In addition, many of these medications cause drowsiness that may limit a person's ability to be active.

Vestibular habituation exercises have been recommended for these non-Ménière's patients. Although the exercises are popular, there are only a few studies in patients with chronic unilateral vestibular dysfunction. Those studies were performed with limited cases or with a wide variety of diagnoses. Herdman et al.,in their review, stressed that studies were retrospective, nonrandomized, consisting of groups that were not comparable, uncontrolled studies and, although they offer interesting descriptions of the patient population, do not provide the evidence necessary to justify the use of these exercises for treatment.

the previous study conducted a research in 2009 to find the Short-term effects of vestibular rehabilitation in patients with chronic unilateral vestibular dysfunction, a randomized controlled study. Their objective was to evaluate the short-term effects of vestibular rehabilitation on a symptom, disability, balance, and postural stability in patients with chronic unilateral vestibular dysfunction. Significant improvements were seen in symptom, disability, balance, and postural stability in chronic unilateral vestibular dysfunction after an exercise program.

in 2013 study was conducted on finding out the effects of Vestibular rehabilitation with virtual reality in Meniere disease. Their aim was to verify the effect of a virtual reality-based balance rehabilitation program for patients with Meniere disease. They concluded that Virtual reality-based balance rehabilitation effectively improved dizziness, quality of life, and limit of stability of patients with Meniere's disease.

in 2006 a study was conducted to Compare between Oculomotor Rehabilitation and Vestibular Electrical Stimulation in Unilateral Peripheral Vestibular Deficit. The aim of their study was to evaluate the effects of oculomotor rehabilitation (group 2) on static balance and a dizziness handicap and to compare those with the effects to vestibular electrical stimulation (group 1). Analysis of the equilibrium system subcomponents did not show any variation. Oculomotor exercises, employed in most rehabilitative protocols and including head movements to improve vestibular adaptation, have proved to reduce the perceived overall impairment and postural sway in patients with recent unilateral vestibular disorders, even though the disorders are not associated with head movements. Comparison of our two study groups did not show any significant difference, revealing that both forms of therapy are effective.

in 2013, a study evaluated the feasibility of integrating vestibular rehabilitation and cognitive behaviour therapy (VR-CBT) for people with persistent dizziness in primary care. This was a prospective single-group pre- and post-test study. Participants reported that the VR-CBT was relevant and led to an improvement in function.Dizziness Handicap Inventory (DHI) scores improved beyond a minimal important change in two out of five participants, and preferred gait velocity increased beyond a minimal important change in two out of three participants. The current tests and VR-CBT treatment protocols were feasible. Some changes are suggested to optimize the protocols, before conducting a randomized controlled trial.

Up-till now a properly structured Circuit Training consisting of Vestibular Rehabilitation exercises, in which each exercise is designed such that it specifically focus on each and every symptom separately has not developed. So, in this research a Circuit Training consisting of Vestibular exercises, each exercise included is focusing on a specific goal separately

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Visual Vertigo Analogue Scale
Time Frame: 4 week
changes from the baseline,this scale is used to measure the intensity of symptoms, 0-10 cm line zero anchor representing no dizziness and 10 anchor representing extreme dizziness or activity avoided due to dizziness
4 week
Vertigo Handicap Questionnaire
Time Frame: 4 week
changes from the baseline, this scale is used to assess the disability level in vestibular impairment. 25 Items measuring Four dimensions(restriction of Activity, social Anxieties, fear of Vertigo, severity of episodes). Item scaling is on 5 points likert scale from 0 (no handicap) to 4 (maximum handicap)
4 week
Dizziness Handicap Inventory
Time Frame: 4 week
changes from the baseline, this test is used to determine the physical, functional and emotional components of Dizziness. Item Scores are summed, there is a maximum score of 100 (28 points for physical, 36 for emotional and 36 for functional and a minimum score of 0. The higher the score, the greater the perceived handicap due to dizziness. Answers are graded: 0 (no), 2 (sometimes), 4 (Yes)
4 week

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Vestibular Disorders Activities of Daily Living Scale
Time Frame: 4 week

4 week
Berg Balance Scale
Time Frame: 4 week
changes from the baseline, Berg balance scale is used for functional balance. participants are asked to perform 14 tasks frequently used in daily life activities. The highest possible score is 56 points. A higher score indicates better balance.
