✦ The Dispatch

Active head-impulse tests may help detect acute unilateral vestibulopathy: a preliminary study

A dispatch from PubMed — filed

Apart from conventional head-impulse tests (i.e., passive HITs), patency of the vestibulo-ocular reflex (VOR) can also be evaluated through self-generated HITs (i.e., active HITs). We aimed to evaluate the usefulness of active (self-generated) HITs in patients with acute unilateral vestibulopathy/vestibular neuritis (AUVP/VN) during the acute stages.

Discussion

Signed responses from readers of the wire.

Clinical Takeaway

Findings are preliminary; no practice change is warranted yet, but active head-impulse testing warrants attention as a potential complement to passive vHIT in acute unilateral vestibulopathy workups.

Why It Matters

If validated in larger trials, active head-impulse testing could expand bedside diagnostic options for acute vestibular disorders without requiring an examiner to physically move the patient's head.

Key Points
  1. 01Preliminary study comparing active (self-generated) vs. passive head-impulse tests for vestibular reflex evaluation.
  2. 02Target condition is acute unilateral vestibulopathy (sudden one-sided inner-ear balance failure).
  3. 03Active HITs are proposed as a complement — not a replacement — to conventional passive VOR testing.
  4. 04Published in Frontiers in Neurology; small/preliminary design limits generalisability.
  5. 05Results could inform future bedside or remote vestibular screening protocols.
Claims & Evidence

Active (self-generated) head-impulse tests can detect acute unilateral vestibulopathy.
