Minimum Stimulus Strategy: A step-by-step diagnostic approach to BPPV.

Area of Science:

• Neurology
• Otolaryngology
• Vestibular System Disorders

Background:

• Benign Paroxysmal Positional Vertigo (BPPV) is a prevalent vestibular disorder causing brief, intense vertigo spells triggered by head movements.
• It results from otoconial debris migrating into the semicircular canals, disrupting normal vestibulo-ocular reflexes.
• Accurate diagnosis is crucial for effective management and patient relief.

Purpose of the Study:

• To introduce and evaluate the Upright BPPV Protocol (UBP) as a diagnostic tool for BPPV.
• To demonstrate the efficacy of the UBP in identifying the affected semicircular canal and side of involvement.
• To highlight the advantages of upright diagnostic maneuvers over traditional supine methods.

Main Methods:

• The UBP involves diagnosing BPPV in a sitting position using gravity-assisted head movements monitored by video-Frenzel goggles.
• Key maneuvers include the upright Head Pitch Test (uHPT) for vertical/horizontal canal assessment and the upright Head Roll Test (uHRT) for horizontal canal side determination.
• Additional tests like uRALP and uLARP can enhance diagnostic accuracy for specific canal involvement.

Main Results:

• The UBP successfully diagnoses most forms of BPPV in the upright position.
• The uHPT effectively differentiates posterior canal involvement, while uHRT aids in identifying horizontal canal laterality.
• The protocol allows for immediate transition to physical treatment post-diagnosis.

Conclusions:

• The Upright BPPV Protocol offers a patient-friendly and efficient method for diagnosing BPPV.
• Performing diagnostic maneuvers in the upright position simplifies the process and facilitates prompt treatment.
• UBP represents a significant advancement in the clinical management of BPPV, enhancing patient experience and therapeutic outcomes.
