OBJECTIVES.: Self-administered canalith repositioning procedure (CRP) for benign paroxysmal positional vertigo (BPPV) is often limited by inaccurate head positioning. We evaluated the feasibility of an inertial measurement unit (IMU)-guided CRP system relative to specialist-performed CRP and explored head motion parameters associated with outcomes....

Discussion
Signed responses from readers of the wire.
Findings are preliminary and feasibility-only; audiologists and vestibular clinicians should monitor the research but no practice change is warranted yet.
If validated in larger trials, IMU-guided self-administered canalith repositioning could extend effective BPPV care beyond the clinic and reduce re-visits.
- 01Wearable IMU sensor designed to provide real-time guidance during self-performed canalith repositioning for BPPV.
- 02Study focus is feasibility — not efficacy — so no conclusions on treatment success rates can be drawn.
- 03Inaccurate head positioning during home maneuvers is a known cause of treatment failure.
- 04Idiopathic BPPV (no identifiable cause) was the target population.
- 05Results lay groundwork for a future powered RCT to test clinical outcomes.
Inaccurate head positioning during canalith repositioning procedures contributes to treatment failure.
