Summary
HITCal software offers a new way to analyze saccadic video head impulse test (vHIT) responses. This open-source tool shows good agreement with human assessment for improved vHIT data exploration.
Area of Science:
- Ophthalmology
- Neurology
- Vestibular System
Background:
- The video head impulse test (vHIT) is crucial for assessing vestibular-ocular reflex function.
- Accurate analysis of vHIT responses, particularly saccades, is essential for clinical diagnosis.
- Existing methods for vHIT analysis may lack comprehensive saccade detection capabilities.
Purpose of the Study:
- To develop and validate HITCal, an open-source software for analyzing saccadic video head impulse test (vHIT) responses.
- To enhance the exploration and measurement of vHIT data, focusing on saccade detection.
Main Methods:
- HITCal software was developed using a computational programming environment.
- Automated saccade analysis was implemented using an experimental algorithm within HITCal.
- A retrospective database of head impulse tests (HITs) from three centers was used for laboratory testing and comparison with human assessment.
Main Results:
- HITCal software was successfully developed and released as open-source, incorporating all planned features.
- The automated saccade detection algorithm in HITCal demonstrated good concordance with human observers (Cohen's kappa coefficient = 0.7).
Conclusions:
- HITCal provides a valuable tool for the analysis and measurement of saccadic vHIT responses.
- The software facilitates enhanced exploration of vHIT data and is recommended for its efficacy.
