    This study introduces a BASIC program to analyze nystagmus data from electronystagmography (ENG) tracings. The program efficiently calculates key metrics like slow phase velocity and fixation indices for improved vestibular assessment.

    Area of Science:

    • Vestibular system research
    • Ophthalmology
    • Neurology

    Context:

    • Electronystagmography (ENG) is a standard diagnostic tool for assessing vestibular function.
    • Nystagmus analysis requires precise measurement of frequency, amplitude, and slow phase velocity.
    • Traditional manual analysis of ENG tracings can be time-consuming and prone to error.

    Purpose:

    • To develop and validate a computational method for analyzing post-caloric nystagmus.
    • To automate the calculation of key nystagmus parameters using a pocket computer program.
    • To enhance the efficiency and accuracy of vestibular function testing.

    Summary:

    • A BASIC program was developed for pocket computers to analyze electronystagmography (ENG) data.
    • The program calculates post-caloric nystagmus frequency and amplitude from ENG tracings.

  • Key derived parameters include slow phase velocity, PD, PL, and ocular fixation indices.

    • Impact:

    • Provides a portable and efficient tool for vestibular laboratories.
    • Facilitates more rapid and objective assessment of vestibular disorders.
    • Potential to improve diagnostic accuracy and patient management in neuro-otology.
