  • Vestibular-Oculomotor Screen (VOMS)

  • Purpose: The VOMS testing was developed to assess vestibular and ocular motor impairments via patient reported symptom provocation after each assessment. The VOMS consists of 5 domains: Smooth Pursuits (0-10), Horizontal and Vertical Saccades (0-10), Convergence (0-10), Horizontal and Vertical Vestibular Reflex (VOR)(0-10), and Visual Motion Sensitivity (0-10). Baseline symptoms are taken in reference to Headaches, Dizziness, Nausea, and Fogginess. The symptoms are reassessed after each test. The testing is looking for provocation of symptoms (2 point increase in any symptom from baseline (Mucha et al. 2015; Elbin et al. 2018). The VOMS test is designed to help establish vestibular / oculomotor dysfunction and help guide rehabilitation and potentially academic accommodations. If positive, initial rehabilitation corresponds to VOMS findings.

  • Additional Vestibular Testing (VOMS Passed)

  • VOR Cancellation: The VOR Cancellation Test (Cerebellar Test) evaluates the cerebellar inhibition on the Vestibulo-Occular Reflex (VOR). The test is performed by having the patient lock both arms in front of them with the fingers laced and the thumbs up (Visual Motion Sensitivity Test). The patient rotates back and forth with the head and arms moving together. Result: The patient’s eyes were able to remain fixed on the thumbs without slippage which indicates the cerebellum is functioning properly.

  • Dynamic Visual Acuity: The patient stands 10' from a wall with the Snellen Eye Chart. Patient reads the chart with their head stationary; the last line read correctly is the "reference line". The examiner manually oscillates the patient's head 20 degrees in each direction at a rhythmic frequency of 2 Hz. The patient reads the chart while the head is being moved and the last line read correctly is the "Test Line". 

    Calculating Score: Subtract "Test Line" from "Reference Line" to find DVA Score. 

    DVA = 0; visual acuity is the same with and without head movements. 

    DVA => 2; dynamic visual acuity is abnormal. If abnormal, management is Gaze Stabilization / Vestibulo-Ocular Rehab.

  • Benign Positional Paroxysmal Vertigo (BPPV)

  • Purpose:  Benign Positional Paroxysmal Vertigo (BPPV) is one of the most common causes of vertigo -- the sudden sensation that a patient is spinning or the inside of the head is spinning. BPPV causes brief episodes of mild to intense vertigo which is usually triggered by specific changes in head position.

  • Dix-Hallpike: Dix-Hallpike tests for otoliths affecting the posterior
    canals (85%-90% of BPPV cases). The test is performed by the patient
    performing 30° of neck extension and 45° of neck rotation. The patient
    is quickly laid down on their back (unaffected side first). The
    examiner observes for nystagmus/vertigo (upbeating nystagmus). There
    may be a latency so the patient is held in the position for up to 30
    seconds.

                   *  

  • Supine Roll Test: If Dix-Hallpike normal but still suspecting BPPV, the Supine Roll Test is performed for Horizontal Canal BPPV. The Supine Roll Test is performed with the patient supine and the head in slight flexion. The head is rotated quickly to the left 90° looking for lateral nystagmus and/or vertigo sensation. The head is brought back to neutral and then quickly rotated to the right 90° and observed for nystagmus and/or vertigo. When present, we will likely be positive bilaterally; however, the effected side will be the side that presents the greatest symptoms.

  • DIAGNOSES (ICD-10)

  • PLAN / RECOMMENDATIONS

  • Time: Today, I spent   *  minutes reviewing the patient’s current status, outcome measures, performing a Vestibulo-Ocular evaluation, discussing my recommendations, documenting my findings and completing the chart note. The patient indicated an understanding of our discussion and we will implement the above treatment plan.
