    Geriatric patients commonly exhibit ankle jerks, contrary to previous reports. This study suggests timing and testing methods may influence findings in elderly individuals.

    Area of Science:

    • Geriatric Medicine
    • Neurology
    • Clinical Assessment

    Background:

    • Ankle reflexes are a key neurological indicator.
    • Previous studies report varying prevalence of ankle jerks in geriatric populations.
    • Standardized assessment protocols are crucial for reliable findings.

    Purpose of the Study:

    • To assess the prevalence of ankle jerks in geriatric patients.
    • To investigate potential factors influencing ankle jerk assessment in this demographic.
    • To compare findings with existing literature on geriatric neurological reflexes.

    Main Methods:

    • Prospective assessment of 200 consecutive geriatric admissions.
    • Ankle jerks evaluated by two independent observers on hospital days 2-3.

  • Utilized a plantar strike method with a standard patellar hammer.

    • Main Results:

    • 188 out of 200 patients (94%) demonstrated present ankle jerks.
    • This prevalence significantly differs from some prior reports.
    • The observed variation may be attributed to testing methodology and timing.

    Conclusions:

    • Ankle jerks are frequently present in geriatric patients.
    • The method and timing of reflex testing can impact observed prevalence.
    • Further research should standardize geriatric neurological assessment techniques.
