  • *Each of these estimates represents the summed values of symptom provocation (0–10) test differences (from baseline) across all symptom tests (headache, fogginess, dizziness, nausea), except near point of convergence (convergence) which measured in centimetres.

  • VOMS, vestibular and ocular motor screening.
