## TL;DR

This study presents a systematic method to accurately diagnose the affected side in lateral canal peripheral positional vertigo using specific tests.

## Contribution

The paper introduces a neurophysiological approach for lateralization in LC-PPV based on endolymphatic flow dynamics.

## Key findings

- The Bow and Lean test and supine roll test were analyzed for endolymphatic flow dynamics.
- A systematic diagnostic approach was developed to determine the affected side in LC-PPV.

## Abstract

Lateral semicircular canal peripheral positional vertigo (LC-PPV) is a common condition, even though accurate determination of the affected side remains a diagnostic challenge that is crucial for effective treatment. The aim of this study is to provide a systematic diagnostic approach for lateralization in LC-PPV, based on analysis of endolymphatic flow dynamics elicited by the Bow and Lean test and supine roll test.
