Effectiveness of Osteopathic Manipulative Treatment (OMT) and Vestibular Rehabilitation Therapy (VRT) in Individuals With Vertigo

Overview

Western University of Health Sciences is seeking men and women to participate in a study on the effectiveness of Osteopathic Manipulative Treatment (OMT) and Vestibular Rehabilitation Therapy (VRT) in patients with vertigo. The purpose of this study is to examine the efficacy of OMT in the treatment of individuals with vertigo, alone and in combination with Vestibular Rehabilitation Therapy (VRT). Because of the health care costs associated with vertigo, the cost effectiveness of OMT and VRT will also be examined.

Full Title of Study: “Effectiveness of Osteopathic Manipulative Treatment (OMT) and Vestibular Rehabilitation Therapy (VRT) Alone or in Combination on Balance and Visual Function in Individuals With Vertigo and Somatic Dysfunction”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Factorial Assignment
    • Primary Purpose: Treatment
    • Masking: Single (Care Provider)
  • Study Primary Completion Date: August 2014

Interventions

  • Other: Osteopathic Manipulative Treatment (OMT)
    • Direct action OMT procedures, including HVLA, involve the application of a force in the direction of restricted joint motion in order to resolve somatic dysfunction. Indirect techniques, including counterstrain, balanced ligamentous tension and myofascial release, entail applying a force away from the restrictive barrier of a joint or soft tissue structure.
  • Other: Vestibular Rehabilitation Therapy (VRT)
    • Participants categorized as having a peripheral motion hypersensitivity will receive habituation exercises that reproduce the provocative motion, seated and standing balance exercises with gaze stabilization, kinesthetic and proprioceptive retraining. Participants will be given a monthly exercise log at onset and will be asked to report exercise levels at subsequent follow up periods.

Arms, Groups and Cohorts

  • Active Comparator: OMT Group
    • Participants will receive Osteopathic Manipulative Treatment (OMT) with the objective of treating diagnosed somatic dysfunction and this will entail the use of specific indirect and direct techniques, including soft tissue, inhibitory, myofascial release, articulatory and high-velocity / low-amplitude (HVLA) techniques.
  • Active Comparator: VRT Group
    • Participants will receive Vestibular Rehabilitation Therapy (VRT), which includes balance exercises in sitting and standing positions that include gaze stabilization, kinesthetic and proprioceptive retraining.
  • Active Comparator: OMT – VRT Group
    • Participants will receive both Osteopathic Manipulative Treatment (OMT) and Vestibular Rehabilitation Therapy (VRT).
  • No Intervention: Control Group

Clinical Trial Outcome Measures

Primary Measures

  • Change from Baseline in Dizziness Handicap Inventory (DHI) at 1 week
    • Time Frame: Baseline to 1 week
    • The Dizziness Handicap Inventory (DHI) is a questionnaire that was developed to measure the self-perceived level of handicap associated with the symptom of dizziness.
  • Change from Baseline in Dizziness Handicap Inventory (DHI) at 3 weeks
    • Time Frame: Baseline to 3 weeks
    • The Dizziness Handicap Inventory (DHI) is a questionnaire that was developed to measure the self-perceived level of handicap associated with the symptom of dizziness.
  • Change from Baseline in Dizziness Handicap Inventory (DHI) at 12 weeks
    • Time Frame: Baseline to 12 weeks
    • The Dizziness Handicap Inventory (DHI) is a questionnaire that was developed to measure the self-perceived level of handicap associated with the symptom of dizziness.
  • Change from Baseline in Computerized Dynamic Posturography (CDP) at 1 week
    • Time Frame: Baseline to 1 week
    • Computerized dynamic posturography (CDP), also called test of balance (TOB), is a non-invasive specialized clinical assessment technique used to quantify the central nervous system adaptive mechanisms (sensory, motor and central) involved in the control of posture and balance, both in normal (such as in physical education and sports training) and abnormal conditions (particularly in the diagnosis of balance disorders and in physical therapy and postural re-education).

    • Evaluation of visual acuity and refractive status, oculomotor function and visual field status.
  • Change from Baseline in Neuro-Optometric Evaluation at 3 weeks
    • Time Frame: Baseline to 3 weeks
    • Evaluation of visual acuity and refractive status, oculomotor function and visual field status.
  • Change from Baseline in Neuro-Optometric Evaluation at 12 weeks.
    • Time Frame: Baseline to 12 weeks
    • Evaluation of visual acuity and refractive status, oculomotor function and visual field status.
