Somatic (headache, dizziness, nausea, fogginess) and eye symptom provocation (eyestrain, eye discomfort, pressure around the eyes) were assessed at baseline and after each visual function test using a Likert scale. Chi\u2010squared tests compared rates of failure and Kruskal\u2013Wallis tests compared measures between groups. Symptom provocation between groups and baseline versus postvisual function tests were compared using one\u2010way ANCOVA and two\u2010way repeated measures ANOVA, respectively.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Patients with PPPD (median 10.0 Diopters (D) IQR [8.8\u201311.6]) had the lowest mean AA measures relative to those with other vestibular disorders (median 13.3D IQR [10.4\u201315.8],\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u00a00.01) and controls (median 13.5D IQR [12.2\u201317.0],\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.001).
