HITCal: a software tool for analysis of video head impulse test responses Rey Martínez, Jorge Batuecas Caletrio, Ángel Matiño, Eusebi Pérez Fernández, Nicolás Algorithm Head impulse test Fitter Saccades analysis Vesticular physiology vHIT VOR [EN] The developed software (HITCal) may be a useful tool in the analysis and measurement of the saccadic video head impulse test (vHIT) responses and with the experience obtained during its use the authors suggest that HITCal is an excellent method for enhanced exploration of vHIT outputs. Objective: To develop a (software) method to analyze and explore the vHIT responses, mainly saccades. Methods: HITCal was written using a computational development program; the function to access a vHIT file was programmed; extended head impulse exploration and measurement tools were created and an automated saccade analysis was developed using an experimental algorithm. For pre-release HITCal laboratory tests, a database of head impulse tests (HITs) was created with the data collected retrospectively in three reference centers. This HITs database was evaluated by humans and was also computed with HITCal. Results: The authors have successfully built HITCal and it has been released as open source software; the developed software was fully operative and all the proposed characteristics were incorporated in the released version. The automated saccades algorithm implemented in HITCal has good concordance with the assessment by human observers (Cohen’s kappa coefficient = 0.7). 2021-02-02T08:39:50Z 2021-02-02T08:39:50Z 2021-02-02T08:39:50Z 2015 info:eu-repo/semantics/article Rey Martínez, J. ; Batuecas Caletrio, A.
