<div>Four interventions for treating AC-BPPV showed a high symptom resolution rate. "All four of the interventions were easy to administer and could be safely applied to individuals of various ages and physical abilities" (Level 4 Evidence; p. 84).</div>
<ul>
<li>The treatment described by Yacovino et al. (2009) resulted in the best one-treatment resolution rate in 100% of patients. This maneuver required the subject to: sit with head in neutral, move to supine position with head extended 30 degrees off the table, move to a flexed position after 30 seconds, and then move to seated position with head in neutral after 30 seconds.</li>
<li>Casani et al. (2011) described an intervention similar to Yacovino et al. (2009) that required longer periods of time to complete the maneuver.</li>
<li>After two treatments, the Korres et al. (2010) treatment resulted in 100% resolution. This treatment involved 45 degree and 90 degree head rotations.</li>
<li>The treatment described by Kim et al. (2005) exhibited resolution after: two treatments in 80% of patients, three treatments in 93% of patients, and four in 97% of patients with AC-BPPV. This treatment included a 45 degree head rotation toward the unaffected side, followed by 45 degree head extension off the end of the table in supine position for 2 minutes, then returning to neutral position for 1 minute. Finally, the patient moves to a seated position with a 30 degree head flex and then back to neutral.</li>
