Effect of height on nerve conduction velocity

R Soudmand, L C Ward, T R Swift

    Neurology
    |April 1, 1982
    PubMed
    Summary

    Body height significantly impacts nerve conduction velocity (NCV) in the legs, but not the arms. Correcting NCV for height improves diagnostic accuracy for nerve conditions.

    Area of Science:

    • Neuroscience
    • Clinical Electrophysiology

    Background:

    • Nerve conduction velocity (NCV) is a key electrophysiological measure.
    • Factors influencing NCV, such as body height, require careful consideration for accurate interpretation.

    Purpose of the Study:

    • To investigate the relationship between body height and NCV in different peripheral nerves.
    • To assess the clinical significance of height-related NCV variations.

    Main Methods:

    • Studied 41 healthy subjects.
    • Measured peroneal, sural, median motor, and sensory NCV.
    • Correlated NCV with subject height and estimated axonal length.

    Main Results:

    • Peroneal and sural NCV showed an inverse correlation with height and axonal length.
    • Median nerve NCV did not significantly correlate with height.
    • Findings support distal axonal tapering in lower extremities.

    Conclusions:

    • Body height is a significant factor affecting lower extremity NCV.
    • Adjusting NCV measurements for height enhances diagnostic sensitivity.
    • Developed regression equations to estimate NCV and latencies based on height, age, and other predictors.
