# Variations in Visual Search Behavior Before Freezing of Gait Episodes: A Case Series

## TL;DR

This study explores how visual search behavior changes before freezing of gait episodes in patients with progressive supranuclear palsy.

## Contribution

The study reveals significant individual variability in gaze behavior during freezing of gait, challenging previous assumptions.

## Key findings

- Substantial individual variability was observed in gaze fixation patterns during freezing of gait episodes.
- Blink rates varied among patients during doorway walking trials.
- The relationship between visual search behavior and freezing is more complex than previously understood.

## Abstract

Reports on the relationship between freezing of gait (FoG) and visual search behavior in Parkinsonian syndrome remain limited. This study aimed to examine gaze behavior in three patients with progressive supranuclear palsy during doorway walking trials. Contrary to previous case reports, substantial individual variability was observed in gaze fixation patterns and blink rates during the FoG episodes. In conclusion, the relationship between visual search behavior and freezing is more complex than previously understood.
